  • Ruby on rails - Radrails IDE - mysql issues.

    - by ThomasReggi
    I have been trying to get Ruby on Rails to migrate a database for the good part of today, the problems all seem to result with this issue, can someone please help! If its a radrails specific problem I guess Ill take this to their forums. Something is telling me this is an easy fix. >rake db:migrate (in C:/Users/Thomas/My Documents/Aptana RadRails Workspace/rp) !!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql. rake aborted! 126: The specified module could not be found. - C:/Ruby/lib/ruby/gems/1.8/gems/mysql-2.8.1-x86-mswin32/lib/1.8/mysql_api.so (See full trace by running task with --trace)

  • 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 :)

  • Survey on logging classes / frameworks / writers

    - by ts
    I am curious what writers (handlers, loggers) are you using. Text file and db its quite obvious, but what are other possibilities ? Firephp maybe (as in Zend_Log), mail, jabber, url ? Is anyone using syslog() or error_log() ? Are you using streams (especially custom ones) ? Are you using custom error levels or you limit yourself to predefined values? Are you logging common php errors / warning / notices? And last question - is there anything new in the town, worth consideration, apart of Zend_Log ? Or are you using your homebrew class?

  • Hash of unique value = unique hash?

    - by Nebs
    Theoretically does hashing a unique value yield a unique value? Let's say I have a DB table with 2 columns: id and code. id is an auto-incrementing int and code is a varchar. If I do ... $code = sha1($id); ... and then store $code into the same row as $id. Will my code column be unique as well? What about if I append the current time? eg: $code = sha1($id . time()); Thanks.

  • capybara selenium and JavaScript Destroy

    - by dorelal
    I am using rails 2.3.5 and this is what I did. I have latest cucumber, cucumber-rails and capybara installed. rails demo cd demo ruby script/generate cucumber --rspec --capybara ruby script/generate feature post title:string body:text published:boolean ruby script/generate scaffold post title:string body:text published:boolean rake db:migrate rake cucumber All the tests are passing. Now I want to test using Javascript.

  • 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!

  • 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

  • Run a shell command with arguments from powershell script

    - by Mike Weerasinghe
    Hello, I need to extract and save a some tables from a remote SQL database using bcp. I would like to write a powershell script to invoke bcp for each table and save the data. So far I have this script that creates the necessary args for bcp. However I can not figure out how to pass the args to bcp. Every time I run the script it just shows the bcp help instead. This must be something really easy that I am not getting. #commands bcp database.dbo.tablename out c:\temp\users.txt -N -t, -U uname -P pwd -S <servername> $bcp_path = "C:\Program Files\Microsoft SQL Server\90\Tools\Binn\bcp.exe" $serverinfo =@{} $serverinfo.add('table','database.dbo.tablename') $serverinfo.add('uid','uname') $serverinfo.add('pwd','pwd') $serverinfo.add('server','servername') $out_path= "c:\Temp\db\" $args = "$($serverinfo['table']) out $($out_path)test.dat -N -t, -U $($serverinfo['uid']) -P $($serverinfo['pwd']) -S $($serverinfo['server'])" #this is the part I can't figure out & $bcp_path $args

  • 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

  • NHibernate CreateSQLQuery data conversion from bit to boolean error

    - by RemotecUk
    Hi, Im being a bit lazy in NHibernate and using Session.CreateSqlQuery(...) instead of doing the whole thing with Lambda's. Anyway what struct me is that there seems to be a problem converting some of the types returned from (in this case the MySQL) DB into native .Net tyes. The query in question looks like this.... IList<Client> allocatableClients = Session.CreateSQLQuery( "select clients.id as Id, clients.name as Name, clients.customercode as CustomerCode, clients.superclient as SuperClient, clients.clienttypeid as ClientType " + ... ... .SetResultTransformer(new NHibernate.Transform.AliasToBeanResultTransformer(typeof(Client))).List<Client>(); The type in the database of SuperClient is a bit(1) and in the Client object the type is a bool. The error received is: System.ArgumentException: Object of type 'System.UInt64' cannot be converted to type 'System.Boolean'. It seems strange that this conversion cannot be completed. Would be greatful for any ideas. Thanks.

  • 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?

  • 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.

  • 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?

  • 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?

  • 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?

  • 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?

  • 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?

  • 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

  • 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

  • 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.

  • 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...
