  • Dynamic mod_rewrite or how to plan a dynamic website

    - by Sophia Gavish
    Hi, I'm trying to make a clean url for a blog on a dynamic website, but I think that the problem is that I don't know how to plan the website schema. I read about how to use mod_rewrite and all I found is how to make "http://www.website.com/?category&date&post-title" to "http://www.website.com/category/date/post-title". that's works o.k for me. The problem is that If my url looks like "http://www.website.com/blog/?id=34" this method won't work as far as I got it. So, I have two questions: 1. Is there a way to use mod_rewrite (maybe read from a txt file) to read the post title of my blog and rewrite my url by date and post-title? 2. Should I rewrite my website to query the data from one index file in the homepage and use mod_rewrite to write the nice url? should I query also the date and the title of the post instead just the post ID?

  • How to retrieve row count of one-to-many relation while also including original entity?

    - by kaa
    Say I have two entities Foo and Bar where Foo has-many Bar's, class Foo { int ImportantNumber { get; set; } IEnumerable<Bar> Bars { get; set; } } class FooDTO { Foo Foo { get; set; } int BarCount { get; set; } } How can I efficiently sum up the number of Bars per Foo in a DTO using a single query, preferrably only with the Criteria interface. I have tried any number of ways to get the original entity out of a query with ´SetProjection´ but no luck. The current theory is to do something like SELECT Foo.*, BarCounts.counts FROM Foo LEFT JOIN ( SELECT fooId, COUNT(*) as counts FROM Bar GROUP BY fooId ) AS BarCounts ON Foo.id=BarCounts.fooId but with Criterias, and I just can't seem to figure out how.

  • PLINQ delayed execution

    - by tbischel
    I'm trying to understand how parallelism might work using PLINQ, given delayed execution. Here is a simple example. string[] words = { "believe", "receipt", "relief", "field" }; bool result = words.AsParallel().Any(w => w.Contains("ei")); With LINQ, I would expect the execution to reach the "receipt" value and return true, without executing the query for rest of the values. If we do this in parallel, the evaluation of "relief" may have began before the result of "receipt" has returned. But once the query knows that "receipt" will cause a true result, will the other threads yield immediately? In my case, this is important because the "any" test may be very expensive, and I would want to free up the processors for execution of other tasks.

  • JPQL get most recent rows

    - by Vinnie
    Let's say I have the following tables my_profile_data ------------- integer: profile_id date: date_changed string: value my_profile ------------- integer: profile_id string: name I want to get the most recent profile information. In plain SQL this would look something like: select mpd.profile_id, mpd.value, max(mpd.date_changed) from my_profile_data mpd, my_profile mp where mpd.profile_id = mp.profile_id and mp.name='The Profile I Want' group by mpd.profile_id I've tried different variants of the following JPQL query, but cant get it to work. SELECT mpd FROM MyProfileData mpd LEFT JOIN (SELECT mpd.profileId profileId, MAX(mpd.dateChanged) FROM MyProfileData mpd LEFT JOIN mp.profile WHERE mp.name = :name GROUP BY mpd.profileId) recent ON (rp.profileid = recent.profileId) Is this query doable in JPA? I'm using EclipseLink as my JPA provider. The innermost exception I get when I try to run this is Caused by: NoViableAltException(81!=[506:7: (n= joinAssociationPathExpression ( AS )? i= IDENT | t= FETCH n= joinAssociationPathExpression )]) at org.eclipse.persistence.internal.jpa.parsing.jpql.antlr.JPQLParser.join(JPQLParser.java:3669) ... 73 more

  • Combine multiple dataset columns to one dataset

    - by Matt
    I have multiple datasets that I would like to combine into one. There is a common ID field that can be associated to each row. Calling Merge on the dataset will add additional rows to the dataset, but I would like to combine the additional columns. There are too many fields to do this in one query and therefore would make it unmanageable. Each individual query would be able to handle ordering to ensure the data is placed in the correct row. For Example lets say I have two queries resulting in two datasets: SELECT ID, colA, colB SELECT colC, colD The resulting dataset would look like ID colA colB colC colD 1 a b c d 2 e f g h Any ideas on ways to accomplish this?

  • Using Raw SQL with Doctrine

    - by Levi Hackwith
    I have some extremely complex queries that I need to use to generate a report in my application. I'm using symfony as my framework and doctrine as my ORM. My question is this: What is the best way to pass in highly-complex sql queries directly to Doctrine without converting them to the Doctrine Query Language? I've been reading about the Raw_SQL extension but it appears that you still need to pass the query in sections (like from()). Is there anything for just dumping in a bunch of raw sql commands?

  • Article search engine in php

    - by Jason
    Hello, I am using sphinx as a search engine on my website its working perfect and I have no complain with it. The only thing it lacks is, it does not allow me to search articles whose query length is more than 15 words. I know in reality people don't use more than 3-4 words i want to use it for finding duplicate contents. I was wondering if there is any alternative solution to sphinx. I want to cope with duplicate contents. My main articles table is in innodb but I am also caching articles into MyISAM table as well for full text searching but when I search an article it takes ages to perform one search. Its not the query problem, i think mysql lacks the fulltext searching facility. Thanks Jason

  • SubSonic Alias/Where Clause

    - by JohnBob
    Hey, I want to convert the following SQL Query to a SubSonic Query. SELECT [dbo].[tbl_Agency].[ParentCompanyID] FROM [dbo].[tbl_Agency] WHERE REPLACE(PhoneNumber, ' ', '') LIKE REPLACE('%9481 1111%', ' ', '') I thought I would do it like below, but I just can't get it to produce valid SQL. //SubSonic string agencyPhoneNumber = "9481 1111"; SubSonic.SqlQuery subQueryagencyPhoneNumber = new SubSonic.Select(Agency.ParentCompanyIDColumn.ColumnName); subQueryagencyPhoneNumber.From(Agency.Schema.TableName); //WHERE subQueryagencyPhoneNumber.Where("REPLACE(" + Agency.PhoneNumberColumn.ColumnName + ", ' ', '')").Like("%" + agencyPhoneNumber + "%"); Does anyone out there know how to fix this - I'm using SubSonic 2.2. I feel like I'm taking crazy pills here - this should be straightforward, right? Cheers, JohnBob

  • Finding the distance between 2 points in Android using Cursor and the distanceTo() method

    - by LordSnoutimus
    Hello, I am trying to calculate the distance between the first GPS point stored in a SQLite database and the last GPs point stored. My code so far is this: private double Distance() { SQLiteDatabase db1 = waypoints.getWritableDatabase(); Cursor cursor = db1.query(TABLE_NAME, FROM, null, null, null, null,ORDER_BY); Cursor cursor1 = db1.query(TABLE_NAME, FROM, null, null, null, null,ORDER_BY); Double lat = cursor.getDouble(2); Double lon = cursor.getDouble(1); cursor.moveToFirst(); cursor.moveToLast(); cursor.close(); distance = cursor.distanceTo(cursor1); } I realise I need to return a value but the error I am receiving is for the distanceTo method "The method distanceTo(Cursor) is undefined for the type Cursor" Thanks.

  • SQL Oracle LEFT JOIN and SUBQUERY error: ORA-00905: missing keyword

    - by Curro
    Hello everyone. Asking for your help on this Oracle query. It's giving me the error 2 "ORA-00905: missing keyword". It was working fine before I added the LEFT JOIN statement. Obviously it won't deliver the information as we need it without the LEFT JOIN statement. Please provide any help to know which keyword is missing in this query Thanks a lot!: DB Tables: DW.TICKETS DW.TICKET_ACTLOG Subquery table: TABLE_RESOLVERS SELECT TO_CHAR(DW.TICKETS.RESOLVED_TIMESTAMP,'YYYY-MM-DD HH24:MI:SS') AS RESOLVED_DATE, DW.TICKETS.SUBJECT, DW.TICKETS.OWNER_CORE_ID, DW.TICKETS.TICKET_NUMBER, TABLE_RESOLVERS.SUBMITTER AS RESOLVER_CORE_ID FROM DW.TICKETS LEFT JOIN (SELECT TICKET_NUMBER, SUBMITTER FROM DW.TICKET_ACTLOG WHERE TYPE = 'Final Resolution' AND (SUBMITTER = 'B02666' OR SUBMITTER = 'R66604') ORDER BY CREATE_TIMESTAMP DESC ) AS TABLE_RESOLVERS ON DW.TICKETS.TICKET_NUMBER = TABLE_RESOLVERS.TICKET_NUMBER WHERE DW.TICKETS.RESOLVED_TIMESTAMP >= to_date('05-03-2010','dd-mm-yyyy') AND DW.TICKETS.RESOLVED_TIMESTAMP < to_date('8-03-2010','dd-mm-yyyy') AND DW.TICKETS.TICKET_NUMBER LIKE 'TCK%' AND DW.TICKETS.TICKET_NUMBER IN (SELECT TICKET_NUMBER FROM DW.TICKET_ACTLOG WHERE (SUBMITTER = 'B02666' OR SUBMITTER = 'R66604') ) ORDER BY DW.TICKETS.CREATE_TIMESTAMP ASC

  • hibernate and ehcache replication

    - by cachingsol
    Hi, I am working on a cache replication solution between nodes Node A - master node = Hibernate + Database + Ehcache as secondary cache Node B - regional node= Ehcache as prmiary cache. no Hibernate Node B is used only as near-by cache for query. Now I am updating data (Say SudentInfo) in Node A, it gets persisted and cached correctly. On replication side (I am using JMS) it sends a message to Node B. But the problem is, the message it sends is of instance CacheEntry(deep Inside Element), there is no way to resurrect the original object (StudentInfo). What I got in node B is CacheEntry with some attributes of Students but not actually an Student Object. Please note that I don't need Hibernate session/persistence in Node B, node B is only for fast query, persistence is done through Node A. So has anybody tried any solution like this? Is there any way to convert CacheEntry to actual object? or Tell ehcache to replicate original object rather than CacheEntry. Thanks for the help

  • Using LINQ to fetch result from nested SQL queries

    - by Shantanu Gupta
    This is my first question and first day in Linq so bit difficult day for me to understand. I want to fetch some records from database i.e. select * from tblDepartment where department_id in ( select department_id from tblMap where Guest_Id = @GuestId ) I have taken two DataTable. i.e. tblDepartment, tblMap Now I want to fetch this result and want to store it in third DataTable. How can I do this. I have been able to construct this query up till now after googling. var query = from myrow in _dtDepartment.AsEnumerable() where myrow.Field<int>("Department_Id") == _departmentId select myrow; Please provide me some link for learning Linq mainly for DataTables and DataSets. EDIT: I have got a very similar example here but i m still not able to understand how it is working. Please put some torch on it.

  • Specifying culture for http request/reponse

    - by Akash
    I have a ReSTful web service which needs to parse culture-sensitive data from the request. This data could either be in an XML body or part of the query string. Is there any acepted way of determining which culture the data is being sent in (and by extension the culture in which the response should be sent)? One option is simply to specify to the clients the culture in which all requests should be sent. A friendlier option seems to be to allow the client to specify the culture. I've considered: a) using the accept-language http header to encode this information. b) using the xml:lang attribute for XML POSTs, and an extra field for query strings (e.g. ...&culture=en-GB) http://www.w3.org/International/questions/qa-accept-lang-locales warns of limitations in using the accept-language header, but most of the warnings seem to center around requests originating from browsers. In my case the requests will come from other applications. All advice greatly appreciated!

  • Full-text indexing? You must read this

    - by Kyle Hatlestad
    For those of you who may have missed it, Peter Flies, Principal Technical Support Engineer for WebCenter Content, gave an excellent webcast on database searching and indexing in WebCenter Content.  It's available for replay along with a download of the slidedeck.  Look for the one titled 'WebCenter Content: Database Searching and Indexing'. One of the items he led with...and concluded with...was a recommendation on optimizing your search collection if you are using full-text searching with the Oracle database.  This can greatly improve your search performance.  And this would apply to both Oracle Text Search and DATABASE.FULLTEXT search methods.  Peter describes how a collection can become fragmented over time as content is added, updated, and deleted.  Just like you should defragment your hard drive from time to time to get your files placed on the disk in the most optimal way, you should do the same for the search collection. And optimizing the collection is just a simple procedure call that can be scheduled to be run automatically.   beginctx_ddl.optimize_index('FT_IDCTEXT1','FULL', parallel_degree =>'1');end; When I checked my own test instance, I found my collection had a row fragmentation of about 80% After running the optimization procedure, it went down to 0% The knowledgebase article On Index Fragmentation and Optimization When Using OracleTextSearch or DATABASE.FULLTEXT [ID 1087777.1] goes into detail on how to check your current index fragmentation, how to run the procedure, and then how to schedule the procedure to run automatically.  While the article mentions scheduling the job weekly, Peter says he now is recommending this be run daily, especially on more active systems. And just as a reminder, be sure to involve your DBA with your WebCenter Content implementation as you go to production and over time.  We recently had a customer complain of slow performance of the application when it was discovered the database was starving for memory.  So it's always helpful to keep a watchful eye on your database.

  • Book Review - Programming Windows Azure by Siriram Krishnan

    - by BuckWoody
    As part of my professional development, I’ve created a list of books to read throughout the year, starting in June of 2011. This a review of the first one, called Programming Windows Azure by Siriram Krishnan. You can find my entire list of books I’m reading for my career here: http://blogs.msdn.com/b/buckwoody/archive/2011/06/07/head-in-the-clouds-eyes-on-the-books.aspx  Why I Chose This Book: As part of my learning style, I try to read multiple books about a single subject. I’ve found that at least 3 books are necessary to get the right amount of information to me. This is a “technical” work, meaning that it deals with technology and not business, writing or other facets of my career. I’ll have a mix of all of those as I read along. I chose this work in addition to others I’ve read since it covers everything from an introduction to more advanced topics in a single book. It also has some practical examples of actually working with the product, particularly on storage. Although it’s dated, many examples normally translate. I also saw that it had pretty good reviews. What I learned: I learned a great deal about storage, and many useful code snippets. I do think that there could have been more of a focus on the application fabric - but of course that wasn’t as mature a feature when this book was written. I learned some great architecture examples, and in one section I learned more about encryption. In that example, however, I would rather have seen the examples go the other way - the book focused on moving data from on-premise to Azure storage in an encrypted fashion. Using the Application Fabric I would rather see sensitive data left in a hybrid fashion on premise, and connect to for the Azure application. Even so, the examples were very useful. If you’re looking for a good “starter” Azure book, this is a good choice. I also recommend the last chapter as a quick read for a DBA, or Database Administrator. It’s not very long, but useful. Note that the limits described are incorrect - which is one of the dangers of reading a book about any cloud offering. The services offered are updated so quickly that the information is in constant danger of being “stale”. Even so, I found this a useful book, which I believe will help me work with Azure better. Raw Notes: I take notes as I read, calling that process “reading with a pencil”. I find that when I do that I pay attention better, and record some things that I need to know later. I’ll take these notes, categorize them into a OneNote notebook that I synchronize in my Live.com account, and that way I can search them from anywhere. I can even read them on the web, since the Live.com has a OneNote program built in. Note that these are the raw notes, so they might not make a lot of sense out of context - I include them here so you can watch my though process. Programming Windows Azure by Siriram Krishnan: Learning about how to select applications suitable for Distributed Technology. Application Fabric gets the least attention; probably because it was newer at the time. Very clear (Chapter One) Good foundation Background and history, but not too much I normally arrange my descriptions differently, starting with the use-cases and moving to physicality, but this difference helps me. Interesting that I am reading this using Safari Books Online, which uses many of these concepts. Taught me some new aspects of a Hypervisor – very low-level information about the Azure Fabric (not to be confused with the Application Fabric feature) (Chapter Two) Good detail of what is included in the SDK. Even more is available now. CS = Cloud Service (Chapter 3) Place Storage info in the configuration file, since it can be streamed in-line with a running app. Ditto for logging, and keep separated configs for staging and testing. Easy-switch in and switch out.  (Chapter 4) There are two Runtime API’s, one of external and one for internal. Realizing how powerful this paradigm really is. Some places seem light, and to drop off but perhaps that’s best. Managing API is not charged, which is nice. I don’t often think about the price, until it comes to an actual deployment (Chapter 5) Csmanage is something I want to dig into deeper. API requires package moves to Blob storage first, so it needs a URL. Csmanage equivalent can be written in Unix scripting using openssl. Upgrades are possible, and you use the upgradeDomainCount attribute in the Service-Definition.csdef file  Always use a low-privileged account to test on the dev fabric, since Windows Azure runs in partial trust. Full trust is available, but can be dangerous and must be well-thought out. (Chapter 6) Learned how to run full CMD commands in a web window – not that you would ever do that, but it was an interesting view into those links. This leads to a discussion on hosting other runtimes (such as Java or PHP) in Windows Azure. I got an expanded view on this process, although this is where the book shows its age a little. Books can be a problem for Cloud Computing for this reason – things just change too quickly. Windows Azure storage is not eventually consistent – it is instantly consistent with multi-phase commit. Plumbing for this is internal, not required to code that. (Chapter 7) REST API makes the service interoperable, hybrid, and consistent across code architectures. Nicely done. Use affinity groups to keep data and code together. Side note: e-book readers need a common “notes” feature. There’s a decent quick description of REST in this chapter. Learned about CloudDrive code – PowerShell sample that mounts Blob storage as a local provider. Works against Dev fabric by default, can be switched to Account. Good treatment in the storage chapters on the differences between using Dev storage and Azure storage. These can be mitigated. No, blobs are not of any size or number. Not a good statement (Chapter 8) Blob storage is probably Azure’s closest play to Infrastructure as a Service (Iaas). Blob change operations must be authenticated, even when public. Chapters on storage are pretty in-depth. Queue Messages are base-64 encoded (Chapter 9) The visibility timeout ensures processing of message in a disconnected system. Order is not guaranteed for a message, so if you need that set an increasing number in the queue mechanism. While Queues are accessible via REST, they are not public and are secured by default. Interesting – the header for a queue request includes an estimated count. This can be useful to create more worker roles in a dynamic system. Each Entity (row) in the Azure Table service is atomic – all or nothing. (Chapter 10) An entity can have up to 255 Properties  Use “ID” for the class to indicate the key value, or use the [DataServiceKey] Attribute.  LINQ makes working with the Azure Table Service much easier, although Interop is certainly possible. Good description on the process of selecting the Partition and Row Key.  When checking for continuation tokens for pagination, include logic that falls out of the check in case you are at the last page.  On deleting a storage object, it is instantly unavailable, however a background process is dispatched to perform the physical deletion. So if you want to re-create a storage object with the same name, add retry logic into the code. Interesting approach to deleting an index entity without having to read it first – create a local entity with the same keys and apply it to the Azure system regardless of change-state.  Although the “Indexes” description is a little vague, it’s interesting to see a Folding and Stemming discussion a-la the Porter Stemming Algorithm. (Chapter 11)  Presents a better discussion of indexes (at least inverted indexes) later in the chapter. Great treatment for DBA’s in Chapter 11. We need to work on getting secondary indexes in Table storage. There is a limited form of transactions called “Entity Group Transactions” that, although they have conditions, makes a transactional system more possible. Concurrency also becomes an issue, but is handled well if you’re using Data Services in .NET. It watches the Etag and allows you to take action appropriately. I do not recommend using Azure as a location for secure backups. In fact, I would rather have seen the examples in (Chapter 12) go the other way, showing how data could be brought back to a local store as a DR or HA strategy. Good information on cryptography and so on even so. Chapter seems out of place, and should be combined with the Blob chapter.  (Chapter 13) on SQL Azure is dated, although the base concepts are OK.  Nice example of simple ADO.NET access to a SQL Azure (or any SQL Server Really) database.

  • Linq-to-SQL statement issue

    - by Anicho
    I am basically looking to bind a search query to a gridview which is nice, but this must be done by a users input query (sort of like a search function). I can get single values and rows returned, but how would I get it to search all columns in my database for the inputted values and return it? My code so far is: Void SearchFunction() { TiamoDataContext context = new TiamoDataContext(); var search = from p in context.UserProfiles where = p.DanceType == UserSearchString select p; UserSearchGrid.DataSource = search; UserSearchGrid.DataBind(); } I tried p.equals but am pretty sure thats not the way to go about it.

  • How do I use WMI with Delphi without drastically increasing the application's file size?

    - by Mick
    I am using Delphi 2010, and when I created a console application that prints "Hello World", it takes 111 kb. If I want to query WMI with Delphi, I add WBEMScripting_TLB, ActiveX, and Variants units to my project. If I perform a simple WMI query, my executable size jumps to 810 kb. I Is there anyway to query WMI without such a large addition to the size of the file? Forgive my ignorance, but why do I not have this issue with C++? Here is my code: program WMITest; {$APPTYPE CONSOLE} uses SysUtils, WBEMScripting_TLB, ActiveX, Variants; function GetWMIstring(wmiHost, root, wmiClass, wmiProperty: string): string; var Services: ISWbemServices; SObject: ISWbemObject; ObjSet: ISWbemObjectSet; SProp: ISWbemProperty; Enum: IEnumVariant; Value: Cardinal; TempObj: OLEVariant; loc: TSWbemLocator; SN: string; i: integer; begin Result := ''; i := 0; try loc := TSWbemLocator.Create(nil); Services := Loc.ConnectServer(wmiHost, root {'root\cimv2'}, '', '', '', '', 0, nil); ObjSet := Services.ExecQuery('SELECT * FROM ' + wmiClass, 'WQL', wbemFlagReturnImmediately and wbemFlagForwardOnly, nil); Enum := (ObjSet._NewEnum) as IEnumVariant; if not VarIsNull(Enum) then try while Enum.Next(1, TempObj, Value) = S_OK do begin try SObject := IUnknown(TempObj) as ISWBemObject; except SObject := nil; end; TempObj := Unassigned; if SObject <> nil then begin SProp := SObject.Properties_.Item(wmiProperty, 0); SN := SProp.Get_Value; if not VarIsNull(SN) then begin if varisarray(SN) then begin for i := vararraylowbound(SN, 1) to vararrayhighbound(SN, 1) do result := vartostr(SN[i]); end else Result := SN; Break; end; end; end; SProp := nil; except Result := ''; end else Result := ''; Enum := nil; Services := nil; ObjSet := nil; except on E: Exception do Result := e.message; end; end; begin try WriteLn('hello world'); WriteLn(GetWMIstring('.', 'root\CIMV2', 'Win32_OperatingSystem', 'Caption')); WriteLn('done'); except on E: Exception do Writeln(E.ClassName, ': ', E.Message); end; end.

  • How to get MAX value of a version-number (varchar) column in T-SQL

    - by Ogre Psalm33
    I have a table defined like this: Column: Version Message Type: varchar(20) varchar(100) ---------------------------------- Row 1: 2.2.6 Message 1 Row 2: 2.2.7 Message 2 Row 3: 2.2.12 Message 3 Row 4: 2.3.9 Message 4 Row 5: 2.3.15 Message 5 I want to write a T-Sql query that will get message for the MAX version number, where the "Version" column represents a software version number. I.e., 2.2.12 is greater than 2.2.7, and 2.3.15 is greater than 2.3.9, etc. Unfortunately, I can't think of an easy way to do that without using CHARINDEX or some complicated other split-like logic. Running this query: SELECT MAX(Version) FROM my_table will yield the erroneous result: 2.3.9 When it should really be 2.3.15. Any bright ideas that don't get too complex?

  • Images missing after moving Django to new server

    - by miszczu
    I'm moving Django project to new server. I'm newbie in Django, and I don't know where should be upload folder. There are all images which should be displayed on website. In config file I haven't seen upload folder I could specify, so I'm guessing it always should be the same location for django projects or I just can't find it. Locations are saved in database. When I've put uploaded files into media folder, so url was like domain.co.uk/media/upload/media/images/year/month/day/image_name.ext and the same is on the old website, images on website ware still missing. All images are visible if I put url by hand, but django doesn't seems to see files. Also I check django log file: 2012-05-30 09:13:33,393 ERROR render: Thumbnail tag failed: [in /usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/templatetags/thumbnail.py (line 49)] Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/templatetags/thumbnail.py", line 45, in render return self._render(context) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/templatetags/thumbnail.py", line 97, in _render file_, geometry, **options File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/base.py", line 50, in get_thumbnail cached = default.kvstore.get(thumbnail) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/kvstores/base.py", line 25, in get return self._get(image_file.key) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/kvstores/base.py", line 123, in _get value = self._get_raw(add_prefix(key, identity)) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/kvstores/cached_db_kvstore.py", line 26, in _get_raw value = KVStoreModel.objects.get(key=key).value File "/usr/lib/python2.6/site-packages/django/db/models/manager.py", line 132, in get return self.get_query_set().get(*args, **kwargs) File "/usr/lib/python2.6/site-packages/django/db/models/query.py", line 344, in get num = len(clone) File "/usr/lib/python2.6/site-packages/django/db/models/query.py", line 82, in __len__ self._result_cache = list(self.iterator()) File "/usr/lib/python2.6/site-packages/django/db/models/query.py", line 273, in iterator for row in compiler.results_iter(): File "/usr/lib/python2.6/site-packages/django/db/models/sql/compiler.py", line 680, in results_iter for rows in self.execute_sql(MULTI): File "/usr/lib/python2.6/site-packages/django/db/models/sql/compiler.py", line 735, in execute_sql cursor.execute(sql, params) File "/usr/lib/python2.6/site-packages/django/db/backends/util.py", line 34, in execute return self.cursor.execute(sql, params) File "/usr/lib/python2.6/site-packages/django/db/backends/mysql/base.py", line 86, in execute return self.cursor.execute(query, args) File "/usr/lib64/python2.6/site-packages/MySQLdb/cursors.py", line 174, in execute self.errorhandler(self, exc, value) File "/usr/lib64/python2.6/site-packages/MySQLdb/connections.py", line 36, in defaulterrorhandler raise errorclass, errorvalue DatabaseError: (1146, "Table 'thumbnail_kvstore' doesn't exist") 2012-05-30 09:13:33,396 DEBUG execute: (0.000) SELECT `freetext_freetext`.`id`, `freetext_freetext`.`key`, `freetext_freetext`.`content`, `freetext_freetext`.`active` FROM `freetext_freetext` WHERE (`freetext_freetext`.`active` = True AND `freetext_freetext`.`key` = office-closed-message ); args=(True, u'office-closed-message') [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] 2012-05-30 09:13:33,399 DEBUG execute: (0.000) SELECT `menus_menu`.`id`, `menus_menu`.`name`, `menus_menu`.`slug`, `menus_menu`.`base_url`, `menus_menu`.`description`, `menus_menu`.`enabled` FROM `menus_menu` WHERE (`menus_menu`.`enabled` = True AND `menus_menu`.`slug` = about ); args=(True, u'about') [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] 2012-05-30 09:13:33,401 DEBUG execute: (0.000) SELECT `menus_menuitem`.`id`, `menus_menuitem`.`menu_id`, `menus_menuitem`.`title`, `menus_menuitem`.`url`, `menus_menuitem`.`order` FROM `menus_menuitem` INNER JOIN `menus_menu` ON (`menus_menuitem`.`menu_id` = `menus_menu`.`id`) WHERE `menus_menu`.`slug` = about ORDER BY `menus_menuitem`.`order` ASC; args=(u'about',) [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] 2012-05-30 09:13:33,404 DEBUG execute: (0.000) SELECT `freetext_freetext`.`id`, `freetext_freetext`.`key`, `freetext_freetext`.`content`, `freetext_freetext`.`active` FROM `freetext_freetext` WHERE (`freetext_freetext`.`active` = True AND `freetext_freetext`.`key` = contactdetails-footer ); args=(True, u'contactdetails-footer') [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] I checked database and there is no table calls thumbnail_kvstore, but I have database backup, and in backup files this table doesn't exist.

  • Programmatically specifying Django model attributes

    - by mojbro
    Hi! I would like to add attributes to a Django models programmatically, at run time. For instance, lets say I have a Car model class and want to add one price attribute (database column) per currency, given a list of currencies. What is the best way to do this? I had an approach that I thought would work, but it didn't exactly. This is how I tried doing it, using the car example above: from django.db import models class Car(models.Model): name = models.CharField(max_length=50) currencies = ['EUR', 'USD'] for currency in currencies: Car.add_to_class('price_%s' % currency.lower(), models.IntegerField()) This does seem to work pretty well at first sight: $ ./manage.py syncdb Creating table shop_car $ ./manage.py dbshell shop=# \d shop_car Table "public.shop_car" Column | Type | Modifiers -----------+-----------------------+------------------------------------------------------- id | integer | not null default nextval('shop_car_id_seq'::regclass) name | character varying(50) | not null price_eur | integer | not null price_usd | integer | not null Indexes: "shop_car_pkey" PRIMARY KEY, btree (id) But when I try to create a new Car, it doesn't really work anymore: >>> from shop.models import Car >>> mycar = Car(name='VW Jetta', price_eur=100, price_usd=130) >>> mycar <Car: Car object> >>> mycar.save() Traceback (most recent call last): File "<console>", line 1, in <module> File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/django/db/models/base.py", line 410, in save self.save_base(force_insert=force_insert, force_update=force_update) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/django/db/models/base.py", line 495, in save_base result = manager._insert(values, return_id=update_pk) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/django/db/models/manager.py", line 177, in _insert return insert_query(self.model, values, **kwargs) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/django/db/models/query.py", line 1087, in insert_query return query.execute_sql(return_id) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/django/db/models/sql/subqueries.py", line 320, in execute_sql cursor = super(InsertQuery, self).execute_sql(None) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/django/db/models/sql/query.py", line 2369, in execute_sql cursor.execute(sql, params) File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/django/db/backends/util.py", line 19, in execute return self.cursor.execute(sql, params) ProgrammingError: column "price_eur" specified more than once LINE 1: ...NTO "shop_car" ("name", "price_eur", "price_usd", "price_eur... ^

  • Get Members of Band

    - by user168083
    If I look at the Freebase page for the band '311', I see Chad Sexton listed. http://www.freebase.com/view/en/311 I am trying to query for the members of a band : { "name" : "311", "/music/artist/album" : [{"name":null, "id":null, "optional": true}], "type|=" : ["/music/artist","/music/musical_group"], "/award/award_winner/awards_won" : ["award":null, "optional" => true], "/award/award_nominated_work/award_nominations" : ["award":null, "optional" => true], "/music/artist/supporting_artists":[{}] } I thought supporting_artists would return the band member names, but the array is always empty. But if I query for all properties related to Chad Sexton, I don't see 311 mentioned. But he is listed as member on the Freebase web info page (which is correct). { "*": null, "name": "Chad Sexton", "type": "/music/artist" } How can I grab the band member names along with the band info?
