• Loading fixtures in django unit tests

  - by loder

  I'm trying to start writing unit tests for django and I'm having some questions about fixtures: I made a fixture of my whole project db (not certain application) and I want to load it for each test, because it looks like loading only the fixture for certain app won't be enough. I'd like to have the fixture stored in /proj_folder/fixtures/proj_fixture.json. I've set the FIXTURE_DIRS = ('/fixtures/',) in my settings.py. Then in my testcase I'm trying fixtures = ['proj_fixture.json'] but my fixtures don't load. How can this be solved? How to add the place for searching fixtures? In general, is it ok to load the fixture for the whole test_db for each test in each app (if it's quite small)? Thanks!

• I'm going to write 'Unit of Work', please help me find out all gimmicks

  - by o..o

  Hi everybody, I'm going to write my own DAL in C#. I decided to use 'Unit of Work' pattern (next mentioned as uow) with request as a scope and Identity map stored in HttpContext.Items. I have right now question about implementing of CRUD methods. How/where are they implemented? Are they implemented in every single business class (as in active records pattern) or are implemented somehow in uow class (if so, how)? I also suppose that I need to use as the scope not just the request, but also the db connection. But how? Should I open the connection a the start of the request and close it on uow disposing? Every advice is strongly appreciated, especially Your "real world" experiences. Thank you all :)

• Web serivce time out errors in delphi

  - by JD

  Hi, I have a client application that makes SOAP requests. I have set the timeout to 20 minutes. However, sometimes I see the timeout error occurring after 10 seconds. I have the following in code: RIO.HTTPWebNode.ReceiveTimeout := 1200000 Do I need to set the ConnectTimeout and SendTimeOut? Currently they are set to the default values of 0. What difference would setting these make? I am using Delphi 2007. Looking further at the error message I see I get "The operation timed out....". So should I be setting my ReceiveTimeOut to zero since I really do not want any timeout at all?

• Accessing unbound DetailsView cell values when Detailsview DefaultMode is Edit

  - by Nickson

  i have a DetailsView that is populated by a Linq to Entities query. Example query is below. Dim Record = From L In db.MyRecords _ Where L.RecordID = 100 _ Select ID = L.RecordID, L.column1, L.column2, L.column3, L.column4 DetailsView2.DataSource = Record DetailsView2.DataBind() The defaultMode for the DetailsView is Edit. Now if this Detailsview was bound to a datasource control, i would convert a column to a templateColumn and programatically access cell values like so Dim NameTextBox As System.Web.UI.WebControls.TextBox = CType(DetailsView2.Rows(1).Cells(1).FindControl("TextBox1"), System.Web.UI.WebControls.TextBox) such that i can then say NameTextBox.Text to get the Name value. But the problem i have is, with this detailsview which is unbound, i have no column at design time to convert to a template, and yet i want to access its cell values. help is appreciated.

• Django - Form validation error

  - by Igor G.

  Hello, I have a model like this: class Entity(models.Model): entity_name = models.CharField(max_length=100) entity_id = models.CharField(max_length=30, primary_key=True) entity_parent = models.CharField(max_length=100, null=True) photo_id = models.CharField(max_length=100, null=True) username = models.CharField(max_length=100, null=True) date_matched_on = models.CharField(max_length=100, null=True) status = models.CharField(max_length=30, default="Checked In") def __unicode__(self): return self.entity_name class Meta: app_label = 'match' ordering = ('entity_name','date_matched_on') verbose_name_plural='Entities' I also have a view like this: def photo_match(request): ''' performs an update in the db when a user chooses a photo ''' form = EntityForm(request.POST) form.save() And my EntityForm looks like this: class EntityForm(ModelForm): class Meta: model = Entity My template's form returns a POST back to the view with the following values: {u'username': [u'admin'], u'entity_parent': [u'PERSON'], u'entity_id': [u'152097'], u'photo_id': [u'2200734'], u'entity_name': [u'A.J. McLean'], u'status': [u'Checked Out'], u'date_matched_on': [u'5/20/2010 10:57 AM']} And form.save() throws this error: Exception in photo_match: The Entity could not be changed because the data didn't validate. I have been trying to figure out why this is happening, but cannot pinpoint the exact problem. I can change my Entities in the admin interface just fine. If anybody has a clue about this I would greatly appreciate it! Thanks, Igor

• Deleting windows.edb and unchecking Indexing service lead to hard drive file records swapping

  - by linni

  I followed the instructions listed here:http://www.mydigitallife.info/2007/09/18/turn-off-and-disable-search-indexing-service-in-windows-xp/ to free up space on hard drive by deleting the windows.edb indexing file... I also stopped windows search service as mentioned in the comments following the article. In addition to unchecking the "Allow Indexing Service to index this disk for fast file searching" check box on the properties dialog for the C:\ drive, I did the same for two usb connected hard drives (J:\ and I:\ ). I'm not sure why I did that, thought it might shrink the windows.edb file so I wouldn't have to delete it (which sounded a bit risky in my ears at the time). The file of course didn't shrink so I ended up deleting it and freeing up over 3 GB of space, yeehaw. However, as soon as I had done this I could not access the usb connected hard drives anymore. The error I got was "I:\photos is not accessible" "The file or directory is corrupted and unreadable" when I tried to open the photos directory on I:\ Here is where I enter the twilight zone... I try disconnecting I:\ usb hard drive. But XP shows me that instead J:\ drive has disconnected and I:\ is still there. So I disconnect both drives and restart the computer. I then connect one drive, but it lists up the contents of the other drive on root level. I tried connecting the drives vice versa and the same thing happens. I try taking one of the hard drives to another computer and when I connect it there it lists up not its own contents but the contents of the other hard drive and gives the same error as above when I try and access any of the folders (even folders on the root that have the same name as folders on the other drive (e.g. J:\photos and I:\photos)??? And no, this is not a me mixing up my drive letters. Computer Manager - Disk management shows the same result as explorer: The drive size is correct (one is 500GB, the other is 640GB) but the drive name is of the opposite drive, as long as the contents. Also, one drive was full of data and the other almost empty but they incorrectly show their free space status of the other drive. Somehow the usb drives seem to have switched file tables, file records, boot records or something, extremely weird! Even weirder, if I try and create a text file or folder on this drive, it works fine, accessing them, saving, whatever, all good, but accessing any other data on the drive gives me an error. Does anyone have a clue what is going on and more importantly, how I can restore the correct folder listings to access my family photos ??? cheers, linni

• How to make QT support HTML 5 database?

  - by Mickey Shine

  I am using Qt 4.7.1 and embedded a webview in my app. But I got the following error when trying to visit http://webkit.org/demos/sticky-notes/ to test the HTML 5 database feature Failed to open the database on disk. This is probably because the version was bad or there is not enough space left in this domain's quota I compiled my static Qt library with the following command: configure --prefix=/usr/local/qt-static-release-db --accessibility --multimedia --audio-backend --svg --webkit --javascript-jit --script --scripttools --declarative --release -nomake examples -nomake demos --static --openssl -I /usr/local/ssl/include -L /usr/local/ssl/lib -confirm-license -sql-qsqlite -sql-qmysql -sql-qodbc

  - by Baget

  Hi I'm developing a Smart card Minidriver and I'm trying to Sign an Email using Outlook 2007. I have implemented all of the necessary functions in the minidriver. I'm able to create a "Smartcard User" certificate and save it and it's private key on the smartcard (using Microsoft Certificate Services via the Minidriver). When I try to sign an EMail via Outlook I'm getting Error Message (Internal Error), the last call to the minidriver is for ReadFile with "cmapfile" When I try to sign an EMail via Outlook with a difference non-smartcard certificate it's work fine. When I try to sign a Data using CryptoAPI (based on Windows SDK Sample) it's working fine. I'm using Windows 7. someone got any idea how to debug this issue? I tried to enable the CAPI2 eventlog, it don't give me any good information.

• [C#][Win32 API] PostMessage Help?

  - by Rudi

  I've looked at sites and MSDN documentation but I still don't understand the last parameter of PostMessage(). On forums in which people ask how to use PostMessage, people reply with one of two implementations: PostMessage(WindowHandle, WM_KEYDOWN, KeyCode, MapVirtualKey(KeyCode, 0) << 16); PostMessage(WindowHandle, WM_KEYDOWN, KeyCode, 0); What's the difference? Why can the last parameter be left as 0 in some instances, but has to be 'shifted' and all that in other instances? Just a quick question. Don't need essay replies (although they would be much appreciated). Any insight is appreciated. Thanks in advance.

• How to organize a large number of objects

  - by shane

  We have a large number of documents and metadata (xml files) associated with these documents. What is the best way to organize them? Currently we put them into a series of nested folders: /repository/category/date(when they were loaded into our db)/document_number.pdf and .xml We use the path as a unique identifier for the document in our system. This is more versatile than putting them all in a single flat folder. also it is independent from our database/application, so we can reload them in case of failure. Yet, it introduces some limitations. for example we can't move the files once they've been placed in this structure, also it takes work to put them this way. What is the best practice? How websites such as Scribd deal with this problem?

• MySQL installation question.

  - by srtriage

  I am far from a DBA and have a question. Recently I installed MySQL. On my machine C:\ is a 50GB partition of two mirrored 10k SAS drives. The remaining space on those drives is allocated to D:. I also have a SSD mounted as E:. When I installed MySQL, I installed it to E:\ assuming that that is where the database information would be held since I had installed it there. I am now seeing C:\ProgramData\MySQL\MySQL Server 5.1\data\peq, peq being the name of my main database. Is my database being stored in C:\ and if so, how do I fix it to store the DB on the SSD?

• Python equivalent of mysql_real_escape_string, for getting strings safely into MySQL?

  - by AP257

  Hi all Is there a Python equivalent of PHP's mysql_real_escape_string? I'm trying to insert some strings into a MySQL db direct from Python, and keep getting tripped up by quotes in the strings. mysql_string = "INSERT INTO candidate (name, address) VALUES " for k, v in v_dict.iteritems(): mysql_string += " ('" + v_dict['name'] + "', '" + v_dict['address'] + "'), " mysql_string += ";" cursor.execute(mysql_string) I've tried re.escape() but that escapes every non-alphanumeric character in the strings, which isn't what I need - I just need to escape single quotes in this instance (plus more generally anything else that might trip up MySQL). Could do this manually I guess, but is there a smarter way to do it in Python?

• Select and Insert across dblink

  - by Domtar

  I am having a bit of trouble with a select into insert across a dblink in oracle 10. I am using the following statement: INSERT INTO LOCAL.TABLE_1 ( COL1, COL2) SELECT COL1, COL2 FROM REMOTE.TABLE1@dblink s WHERE COL1 IN ( SELECT COL1 FROM WORKING_TABLE) When I run the statement the following is what gets run against the remote server on the DB Link: SELECT /*+ OPAQUE_TRANSFORM */ "COL1", "COL2" FROM "REMOTE"."TABLE1" "S" If I run the select only and do not do the insert into the following is run: SELECT /*+ */ "A1"."COL1" , "A1"."COL2" FROM "REMOTE"."TABLE1" "A1" WHERE "A1"."COL1" = ANY ( SELECT "A2"."COL1" FROM "LOCAL"."TABLE1"@! "A2") The issue is in the insert case the enitre table is being pulled across the dblink and then limited localy which takes a fair bit of time given the table size. Is there any reason adding the insert would change the behavior in this manner?

• C# Class Library wont register for COM

  - by Jordan S

  Hello All, I am trying to gain access to a .NET class library in Microsoft Excel. To do this I know that the .NET class library must be registered with COM. So I tried going to my Assembly Info and Setting COM Visible to true. Then on the build tab I set Register for COM Interop for true also. I checked the AssemblyInfo.cs file and it does contain [assembly: ComVisible(true)]. But for some reason when I try to add a reference to the Class Lib in Excel the namespace does not show up in the list. I made a quick test Class library with nothing in it and did the same thing (set COM Vis = true , and Register For COM Interop = true) and that one does show up on the list of available references. I can't figure out what the difference is between the two classes. I am not sure if my class is actually being registered for COM interop or not. Does anyone know what I can do to fix this???

• double.NaN Equality in MS Test

  - by RichK

  Why am I getting this result? [TestMethod] public void nan_test() { Assert.AreEqual(1, double.NaN, 1E-1); <-- Passes Assert.AreEqual(1, double.NaN); <-- Fails } What difference does the delta have in asserting NaN equals a number? Surely it should always return false. I am aware of IsNaN, but that's not useful here (see below). Background: I have a function returning NaN (erroneously) , it was meant to be a real number but the test still passed. I'm using the delta because it's double precision equality, the original test used 1E-9.

• How to use LIKE query in sqlite & iPhone

  - by 4thSpace

  I'm using the following for a LIKE query. Is this technique for LIKE correct? selectstmtSearch = nil; if(selectstmtSearch == nil){ const char *sql = "SELECT col1, col2 FROM table1 t1 JOIN table2 t2 ON t1.cityid = t2.cityid where t1.cityname like ?001 order by t1.cityname"; if(sqlite3_prepare_v2(databaseSearch, sql, -1, &selectstmtSearch, NULL) == SQLITE_OK) { sqlite3_bind_text(selectstmtSearch, 1, [[NSString stringWithFormat:@"%%%@%%", searchText] UTF8String], -1, SQLITE_TRANSIENT); } } The problem I'm having is after a few uses of this, I get an error 14 on sqlite3_open(), which is unable to open database. If I replace the LIKE with something such as: SELECT col1, col2 FROM table1 t1 JOIN table2 t2 ON t1.cityid = t2.cityid where t1.cityname = ? order by t1.cityname It works fine. I do open/close the DB before after the above code. Is there a way to troubleshoot exactly why the database can't be opened and what its relationship to my LIKE syntax is?

• How to link a SQlite Extension Source File into Xcode for iPhone?

  - by crunchyt

  I use a statically linked library for Sqlite in an iPhone Xcode project. I am now trying to include a .C extension to Sqlite in this project. However, I am having trouble making the Sqlite in the build SEE the extension. The statically linked Sqlite library works fine. Also the .C extension works on my desktop, and builds fine as a statically linked library in Xcode. However, the custom functions it defines are missing when called. For example, I load the extension as so with no errors. SELECT load_extension('extension_name.so'); But when I try to call a function defined in the extension, I get this message DB Error: 1 "no such function: custom_function" Does anyone know much about linking a Sqlite extension into an Xcode project?

• Background processing in rails

  - by hashpipe

  Hi, This might seem like a FAQ on stackoverflow, but my requirements are a little different. While I have previously used BackgroundRB and DJ for running background processes in ruby, my requirement this time is to run some heavy analytics and mathematical computations on a huge set of data, and I need to do this only about the first 15 days of the month. Going by this, I am tempted to use cron and run a ruby script to accomplish this goal. What I would like to know / understand is: 1 - Is using cron a good idea (cause I'm not a system admin, and so while I have basic idea of cron, I'm not overly confident of doing it perfectly) 2 - Can we somehow modify DJ to run only on the first 15 days of the month (with / without using cron), and then just stop and exit once all the jobs in the queue for the day are over (don't want it to ping the DB every time for a new job...whatever the jobs will be in the queue when DJ starts, that will be all). I'm not sure if I have put the question in the right manner, but any help in this direction will be much appreciated. Thanks

• [LINQ]InsertOnSubmit NullReferenceException

  - by Kurresmack

  Hello, I have a rather annoying issue with LinqToSql. I have created a class that is derived from the class in the DataContext. The problem is that as soon as I use "InsertOnSubmit(this);" on this derived class I get a NullReferenceException. I've seen some people with the same issue. However they've used a custom constructor and solved the issue by calling ": this()" like this thread http://social.msdn.microsoft.com/Forums/en-US/linqprojectgeneral/thread/0cf1fccb-6398-4f16-920b-adef9dc4ac9f The difference is that I use a default constructor which causes the base constructor to be called so there should not be any problem! Could someone please help me with this, starts to get annoying! Thanks :)

• MembershipProvider, IPrincipal, IIdentity?

  - by MRFerocius

  Hello guys; I have a conceptual question... I am making an Intranet application (Web platform) for a company. I have a SQL Server DB with these tables: Users (userID, userName, userPass, roleID) Roles (roleID, roleName) Pages (pageID, pageURL) RolesXPages(pageID, roleID) How is the best way to create a structure to store all this information while the user navigates the site, I mean, on the thread I should be able to check his role, his pages (the ones he can access) I have been reading and there is a lot of stuff there where Im confused, I saw the MembershipProvider, IPrincipal, IIdentity, etc classes but Im not sure what should be the best one for me. Any thoughts... Thanks in advance! Edit: Everytime gets more confusing... I just want to handle those structures at runtime and be able to mantain state during page callbacks or changing pages...

• Include params/request information in Rails logger?

  - by Dan Hill

  Hi everyone, I'm trying to get some more information into my Rails logs, specifically the requested URI or current params, if available (and I appreciate that they won't always be). However I just don't seem able to. Here's what I've done so far: #config/environments/production.rb config.logger = Logger.new(config.log_path) config.log_level = :error config.logger.level = Logger::ERROR #config/environment.rb class Logger def format_message(level, time, progname, msg) "**********************************************************************\n#{level} #{time.to_s(:db)} -- #{msg}\n" end end So I can customize the message fine, yet I don't seem to be able to access the params/request variables here. Does anyone know if this is possible, and if so how? Or if there's a better way to get this information? (Perhaps even something Redis based?) Thanks loads, Dan

• Share application in local network

  - by hedgehogrider

  I would like to eventually create a managerial program that shares and updates information for multiple computers that are on the same network. I am fairly familiar with Python, C++ and a bit of Java, is there a library I could use with any of these languages to design such a program? I could probably create the local interface from where I am right now, but when it comes to packing and sharing data I could not be more clueless; any advice would be platinum. The program will need to differentiate between administrative and user access if that makes a difference.

• SqlDataReader / DbDataReader implementation question

  - by Jose

  Does anyone know how DbDataReaders actually work. We can use SqlDataReader as an example. When you do the following cmd.CommandText = "SELECT * FROM Customers"; var rdr = cmd.ExecuteReader(); while(rdr.Read()) { //Do something } Does the data reader have all of the rows in memory, or does it just grab one, and then when Read is called, does it go to the db and grab the next one? It seems just bringing one into memory would be bad performance, but bringing all of them would make it take a while on the call to ExecuteReader. I know I'm the consumer of the object and it doesn't really matter how they implement it, but I'm just curious, and I think that I would probably spend a couple hours in Reflector to get an idea of what it's doing, so thought I'd ask someone that might know. I'm just curious if anyone has an idea.
