• What kind of authorization I should use for my facebook application

  - by JSmith

  I am building a social reader Facebook application using Django where I am using Google Data API (Blogger API). But I am unable to deal with the authorization step to use the API (currently using ClientLogin under development). I tried to read the OAuth documentation but couldn't figure out how to proceed. I don't want my users to provide any login credentials for google.. which makes the app completely absurd. So, can anyone help me on my project and tell me what kind of authorization I should actually use and how ? (I am using gdata lib)

• Is backing up a MySQL database in GIT a good idea?

  - by wobbily_col

  I am trying to improve the backup situation for my application. I have a Django application and MySQL database. I read an article suggesting backing up the database in Git. On the one hand I like it, as it will keep a copy of the data and the code in synch. But GIT is a designed for code, not for data. As such it will be doing a lot of extra work diffing the mysql dump every commit, which is not really necessary. If I compress the file before storing it, will git diff the files? (The dump file is currently 100MB uncompressed, 5.7Mb when bzipped). Edit: the code and database schema definitions are already in GIT, it is really the data I am concerned about backing up now.

• py.test import context problems (causes Django unit test failure)

  - by dhill

  I made a following test: # main.py import imported print imported.f.__module__ # imported.py def f(): pass # test_imported.py (py.test test case) import imported def test_imported(): result = imported.f.__module__ assert result == 'imported' Running python main.py, gives me imported, but running py.test gives me error and result value is moduletest.imported (moduletest is the name of the directory I keep the test in. It doesn't contain __init__.py, moduletest is the only directory containing *.py files in ~/tmp). How can I fix result value? The long story: I'm getting strange errors, while testing Django application. A call to reverse() from (django.urlresolvers). with function object foo as argument in tests crashes with NoReverseMatch: Reverse for 'site.app.views.foo'. The same call inside application works. I checked and it is converted to 'app.views.foo' (without site prefix). I first suspected my customised test setup for Django, but then I made above test.

• Windows + Django + mod_wsgi = "DLL load failed"

  - by Kyle MacFarlane

  For a long time I was using Python 2.5 to do all this fine but recently upgraded to 2.7 since building stuff for 2.5 is a real pain. I also updated mod_wsgi to 3.3 for Python 2.7. Everything is working fine with Apache + mod_wsgi on CentOS and also in the Django runserver on both Windows and CentOS, but not with Apache + mod_wsgi on Windows. Whenever I try to access a page in my Django app I get the following (note that Apache starts fine): ImportError at / DLL load failed: The specified module could not be found. Which is caused by things like: from Crypto.Cipher import AES Etree and others cause the exact same error and it is not limited to any specific packages. Anything with pyd files fails. Googling around suggests reinstalling Python "for all users", but the installer doesn't give you that option anymore anyway. For good measure I've tried reinstalling Python 2.7 as an administrator and also told it to register itself as the default version of Python but neither helped. I think the solution might have something to do with: The fact that I have 2.5, 2.6 and 2.7 installed on this machine and mod_wsgi might be loading the DLLs for 2.5 instead of 2.7. Something to do with WSGIPythonPath, which I usually don't need to set.

• How to write php->mysql queries?

  - by Bluemagica

  Is there any good tutorial that has all the basic rules for writing queries to store $_Post vars from php to mysql? Like when to use backticks and singleqoutes, and how to safely write code with functions like get_magic_quotes_gpc()? Another thing is, assuming there is no javascript validation(since the user can easily turn it off), how should I handle empty form fields being sent as empty $_post variables and throwing errors? Do I have to use isset() call on all the post variables? What is the best way to handle users turning off javascript validation on a form?

• Help combining these two queries

  - by Horace Loeb

  I need a SQL query that returns results matched by EITHER of the following SQL queries: Query 1: SELECT "annotations".* FROM "annotations" INNER JOIN "votes" ON "votes".voteable_id = "annotations".id AND "votes".voteable_type = 'Annotation' WHERE (votes.vote = 't' AND votes.voter_id = 78) Query 2: SELECT "annotations".* FROM "annotations" INNER JOIN "songs" ON "songs".id = "annotations".song_id INNER JOIN "songs" songs_annotations ON "songs_annotations".id = "annotations".song_id INNER JOIN "users" ON "users".id = "songs_annotations".state_last_updated_by_id WHERE (annotations.referent IS NOT NULL AND annotations.updated_at < '2010-04-05 01:51:24' AND (body = '?' OR body LIKE '%[?]%') AND ((users.id = songs.state_last_updated_by_id and users.needs_edit = 'f' and songs.state != 'work_in_progress') OR (songs.state = 'published')) Here's what I tried, but it doesn't work: SELECT "annotations".* FROM "annotations" INNER JOIN "songs" ON "songs".id = "annotations".song_id INNER JOIN "songs" songs_annotations ON "songs_annotations".id = "annotations".song_id INNER JOIN "users" ON "users".id = "songs_annotations".state_last_updated_by_id INNER JOIN "votes" ON "votes".voteable_id = "annotations".id AND "votes".voteable_type = 'Annotation' WHERE ((votes.vote = 't' and votes.voter_id = 78) OR (annotations.referent IS NOT NULL and annotations.updated_at < '2010-04-05 01:43:52' and (annotations.body = '?'

• Simpler Linq to XML queries with the DLR

  - by Xavier

  Hi folks, I have a question regarding Linq to XML queries and how we could possibly make them more readable using the new dynamic keyword. At the moment I am writing things like: var result = from p in xdoc.Elements("product") where p.Attribute("type").Value == "Services" select new { ... } What I would like to write is something like: var result = from p in xdoc.Products where p.Type == "Services" select new { ... } I know I can do this with Linq to XSD which is pretty good already, but obviously this requires an XSD schema and I don't always have one. I am sure there should be a way to achieve this using the new dynamic features of .NET 4.0 but I'm not sure how or if anyone already had a go at this. Obviously I would loose some of the advantages of Linq to XSD (typed members and compile time checks) but it wouldn't be worse than the original solution and would certainly be more readable. Anyone has an idea? Thanks

• Using sub filters/queries in Google App Engine

  - by fredrik

  Hi, I'm trying to use figure out how to sub query a query that uses a filter. From what I've figured out so far while using .filter() it changes the original query, that leads to a second .filter() would also have to match the first filter. I would like to make something like this: modules = data.Modules.all().filter('page = ', page.key()) modules.filter('name = ', 'Test') modules.filter('name = ', 'Test2') I can't get the "Test2" filter to work. The only solution I have at the moment is to make all new queries. data.Modules.all().filter('page = ', page.key()).filter('name = ', "Test").get() data.Modules.all().filter('page = ', page.key()).filter('name = ', "Test2").get() Or write the same as an GQL. But for me it seams quite stupid way to go. I've looked at using ancestors, but I don't quite understand it and honestly don't know if that's the way to go. Any ideas? ..fredrik

• How can I run NHibenate queries asynchronously?

  - by andrey-tsykunov

  Hello, One way to increase scalability of the server application is to run IO-bound operation (reading files, sockets, web requests, database requests etc) asynchronously. This does not mean run then in the ThreadPool which will just block threads while operation is being executed. The correct way is to use asynchronous API (BeginRead, BeginGetResponse, BeginExecuteReader etc). The problem is well described in CLR vi C# book. Here is some article about asynchronous queries in Linq to SQL. Are any ways to execute Nhibernate query asynchonously? What about Linq to NHibernate? Thank you, Andrey

• Need to debug LINQ simple queries in Visual Studio 2010

  - by maxima120

  I often get in a position when I need to know why my LINQ doesnt work as intended... I use object collections and extensions. I dont want spend more than couple of minutes on it. LINQ supposed to make developer's life easier not harder. I hoped VS 2010 will have it fixed but I now use RC and it still doesnt let me type LINQ and check what is going on... Says as before "Expression cannot contain lambda expressions"... Is there some add-on for Visual Studio so I can quickly and effectively run ad-hoc queries and find out what is going on and where I am wrong?

• Making complex queries through SQLiteDatabase

  - by Luca

  Hi! I'm using the Android MediaProvider application to get information regarding the resources registered in the media library. The only way I found to do this is to use the ContentProvider class provided by the MediaProvider application. Unfortunately, it seems to me this is quite a limitation, isn't it? Is it possible this way to create complex queries with subqueries and using other functions of SQLite? I thought that it may be possible using the SQLiteDatabase class, but it seems it is not possible to open the database directly with its path, and anyway, the query method seems not to allow subqueries. Any solution to this? Thanks!

• Linq To Sql: Compiled Queries and Extension Methods

  - by Beni

  Hi community, I'm interessted, how does Linq2Sql handles a compiled query, that returns IQueryable. If I call an extension method based on a compiled query like "GetEntitiesCompiled().Count()" or "GetEntitiesCompiled().Take(x)". What does Linq2Sql do in the background? This would be very bad, so in this situation I should write a compiled query like "CountEntitiesCompiled". Does he load the result (in this case "GetEntitiesCompiled()") into the memory (mapped to the entity class like "ToList()")? So what situations make sense, when the compiled queries return IQueryable, that query is not able to modify, before request to the Sql-Server. So in my opinion I can just as good return List. Thanks for answers!

• Compiled Queries and "Parameters cannot be sequences"

  - by David B

  I thought that compiled queries would perform the same query translation as DataContext. Yet I'm getting a run-time error when I try to use a query with a .Contains method call. Where have I gone wrong? //private member which holds a compiled query. Func<DataAccess.DataClasses1DataContext, List<int>, List<DataAccess.TestRecord>> compiledFiftyRecordQuery = System.Data.Linq.CompiledQuery.Compile <DataAccess.DataClasses1DataContext, List<int>, List<DataAccess.TestRecord>> ((dc, ids) => dc.TestRecords.Where(tr => ids.Contains(tr.ID)).ToList()); //this method calls the compiled query. public void FiftyRecordCompiledQueryByID() { List<int> IDs = GetRandomInts(50); //System.NotSupportedException //{"Parameters cannot be sequences."} List<DataAccess.TestRecord> results = compiledFiftyRecordQuery (myContext, IDs); }

• Using a table-alias in Kohana queries?

  - by Aristotle

  I'm trying to run a simple query with $this->db in Kohana, but am running into some syntax issues when I try to use an alias for a table within my query: $result = $this->db ->select("ci.chapter_id, ci.book_id, ci.chapter_heading, ci.chapter_number") ->from("chapter_info ci") ->where(array("ci.chapter_number" => $chapter, "ci.book_id" => $book)) ->get(); It seems to me that this should work just fine. I'm stating that "chapter_info" ought to be known as "ci," yet this isn't taking for some reason. The error is pretty straight-forward: There was an SQL error: Table 'gb_data.chapter_info ci' doesn't exist - SELECT `ci`.`chapter_id`, `ci`.`book_id`, `ci`.`chapter_heading`, `ci`.`chapter_number` FROM (`chapter_info ci`) WHERE `ci`.`chapter_number` = 1 AND `ci`.`book_id` = 1 If I use the full table name, rather than an alias, I get the expected results without error. This requires me to write much more verbose queries, which isn't ideal. Is there some way to use shorter names for tables within Kohana's query-builder?

• How to implement dynamic queries for MNesia?

  - by Kerem

  I'm trying to implement a function that generates dynamic queries for MNesia. For example, when function is called with these arguments; dyn_query(list, person, [name, age], ["jack", 21]) I want to query MNesia to list items whose name is "jack" and age is 21 in person table. I've tried to implement this by using qlc:q(ListComprehension) and qlc:string_to_handle("ListComprehension"). First failed because of compile errors, compiler didn't let me to use functions instead of ListComprehentions and variables instead of record names like "Item#Table.Member". Second failed, because erl_eval couldn't handle records and throwed exceptions like {undefined_record, person}. Which method should I use? How could i solve these problems? Or should I use a different method? Thanks.

• web2py error while using distinct in the queries

• Minimizing SQL queries using join with one-to-many relationship

  - by Brian

  So let me preface this by saying that I'm not an SQL wizard by any means. What I want to do is simple as a concept, but has presented me with a small challenge when trying to minimize the amount of database queries I'm performing. Let's say I have a table of departments. Within each department is a list of employees. What is the most efficient way of listing all the departments and which employees are in each department. So for example if I have a department table with: id name 1 sales 2 marketing And a people table with: id department_id name 1 1 Tom 2 1 Bill 3 2 Jessica 4 1 Rachel 5 2 John What is the best way list all departments and all employees for each department like so: Sales Tom Bill Rachel Marketing Jessica John Pretend both tables are actually massive. (I want to avoid getting a list of departments, and then looping through the result and doing an individual query for each department). Think similarly of selecting the statuses/comments in a Facebook-like system, when statuses and comments are stored in separate tables.

• NHibernate Linq queries not returning data saved in the same transaction

  - by Andrew

  Hi, I have a situation where I am using NHibernate in a WCF service and using a TransactionScope for the transaction management. NHibernate enlists in the ambient transaction fine, but, any changes I make and save inside the transaction, are not visible to any queries I make while still in that transaction. So if I add an entity and session.save() it, then further on in the code, there is a linq query against that entities table, the entity I just added is not returned. Strangely this seems to work fine if I use explicit NHibernate transactions in my tests. Anyone have any ideas as to why and what I can do about it? Many thanks Andrew

• C# failing LDAP queries

  - by jpkomick

  I'm trying to access an LDAP directory via the SearchRequest object in C#. I can make the same calls via an LDAP library running in and iPhone app, as well as directly via a terminal session. However, the C# queries all seem to fail. var search = new SearchRequest("ou=calendar,dc=ualberta,dc=ca", "term=*,course=094398,class=*", System.DirectoryServices.Protocols.SearchScope.Subtree, attributeLst); This returns a list of terms for the course calendar. However, making the following calls won't return results for specific courses var search = new SearchRequest("ou=calendar,dc=ualberta,dc=ca", "term=1330,course=094398", System.DirectoryServices.Protocols.SearchScope.Subtree, attributeLst); The attributeLst object has proper attribute names included, but the query always returns with zero results. Any suggestions anyone has would be greatly appreciated. Thanks.

• MySQL slow queries

  - by jack

  The MySQL slow query log often shows a bunch of following entries in sequence. SET timestamp=1268999330; commit; # User@Host: username[username] @ localhost [] # Query_time: 4.172700 Lock_time: 0.000000 Rows_sent: 0 Rows_examined: 0 SET timestamp=1268999330; commit; # User@Host: username[username] @ localhost [] # Query_time: 3.628924 Lock_time: 0.000000 Rows_sent: 0 Rows_examined: 0 SET timestamp=1268999330; commit; # User@Host: username[username] @ localhost [] # Query_time: 3.116018 Lock_time: 0.000000 Rows_sent: 0 Rows_examined: 0 ... Usually 6-7 "commit" queries in sequence. Anyone what they are and what's the preceding query of each of them? Thanks in advance.

• how to combine these queries

  - by mmcgrail

  and get meaningful results. Currently I am running these three queries: SELECT t.type,t.id,s.title FROM db1.tags t INNER JOIN db1.st s ON s.id=t.id WHERE id LIKE '%%' AND t.tag='foo' AND t.type='s' ORDER BY tag desc LIMIT 0, 19 SELECT t.type,t.id,v.title FROM db1.tags t INNER JOIN db1.vi v ON v.id=t.id WHERE id LIKE '%%' AND t.tag='foo' AND t.type='v' ORDER BY tag desc LIMIT 0, 19 SELECT t.type,t.id,i.ca AS title FROM db1.tags t INNER JOIN db2.tablename i ON i.id=t.id WHERE id LIKE '%%' AND t.tag='foo' AND t.type='i' ORDER BY tag desc LIMIT 0, 19 then trying to combine the data results but what I would really prefer is if I could combine them into a single query. Any thoughts?

• Hierarchical Hibernate, how many queries are executed?

  - by ghost1

  So I've been dealing with a home brew DB framework that has some seriously flaws, the justification for use being that not using an ORM will save on the number of queries executed. If I'm selecting all possibile records from the top level of a joinable object hierarchy, how many separate calls to the DB will be made when using an ORM (such as Hibernate)? I feel like calling bullshit on this, as joinable entities should be brought down in one query , right? Am I missing something here? note: lazy initialization doesn't matter in this scenario as all records will be used.

• Where to put conditionals in ANSI-syntax SQL queries

  - by RenderIn

  What's the difference between these two queries? I've been resistant to jumping on the ANSI-syntax bandwagon because I have not been able to unravel various syntactical ambiguities. Is 1) returning the product of the join and only then filtering out those joined records which have weight = 500? And is 2) filtering out those prior to the join? Is 2 bad syntax? Why might I use that? 1: SELECT SOMETHING FROM FOO INNER JOIN BAR ON FOO.NAME = BAR.NAME WHERE BAR.WEIGHT < 500 2: SELECT SOMETHING FROM FOO INNER JOIN BAR ON FOO.NAME = BAR.NAME AND BAR.WEIGHT < 500

• Advanced queries in HBase

  - by Teflon Ted

  Given the following HBase schema scenario (from the official FAQ)... How would you design an Hbase table for many-to-many association between two entities, for example Student and Course? I would define two tables: Student: student id student data (name, address, ...) courses (use course ids as column qualifiers here) Course: course id course data (name, syllabus, ...) students (use student ids as column qualifiers here) This schema gives you fast access to the queries, show all classes for a student (student table, courses family), or all students for a class (courses table, students family). How would you satisfy the request: "Give me all the students that share at least two courses in common"? Can you build a "query" in HBase that will return that set, or do you have to retrieve all the pertinent data and crunch it yourself in code?
