• Django: Generating a queryset from a GET request

  - by Nimmy Lebby

  I have a Django form setup using GET method. Each value corresponds to attributes of a Django model. What would be the most elegant way to generate the query? Currently this is what I do in the view: def search_items(request): if 'search_name' in request.GET: query_attributes = {} query_attributes['color'] = request.GET.get('color', '') if not query_attributes['color']: del query_attributes['color'] query_attributes['shape'] = request.GET.get('shape', '') if not query_attributes['shape']: del query_attributes['shape'] items = Items.objects.filter(**query_attributes) But I'm pretty sure there's a better way to go about it.

• Is it worth moving from stored procedures to linq ?

  - by Josef

  I'm looking at standardizing programming in an organisaiton. Half uses stored procedures and the other half Linq. From what i've read there is still some debate going on on this topic. My concern is that MS is trying to slip in it's own proprietry query language 'linq' to make SQL redundant. If a few years back microsoft had tried to win customers from oracle and sybase with their MSSQL database and stated that it didn't use SQL by their own proprietry query langues ie linq. I doubt many would have switched. I believe that is exactly what is happening now by introducting it into the applicaiton business layer. I have used MS for many years but there is one gripe that I have with them and that is that they change their direction a lot. By a lot I mean new releases of .net, silverlight etc are more than 30% different from previous version. So by the time you become productive a new release is on the way. As things stand now a web developer using .net would need to know either vb.net or c#, xml, xaml,javascript,html, sql and now linq. That doesn't make for good productivity in my books. My concern is that once we all start using linq MS will start changing it between releases. and it will become an ever changing landscape. I believe that 'linq to sql' has already been deprecated. At leas with SQL we are dealing with a more stable and standardized language. Are we looking at a programming revolution or a marketing campaign? As far as I know other languages like Cobol have stayed the same for years. A cobol program from 20 years ago could pick up todays code and start working on it. Could a Vb3 person work on a modern .net web app ? Would these large changes need to be made if the underlying original foundation had been sound ? I worry about following MS shaking roadmap with it's deadends and double backs. are there any architects out there who feel the same ? regards Josef

• What is the difference between a segmentation fault and a stack overflow?

  - by AruniRC

  For example when we call say, a recursive function, the successive calls are stored in the stack. However, due to an error if it goes on infinitely the error is 'Segmentation fault' (as seen on GCC). Shouldn't it have been 'stack-overflow'? What then is the basic difference between the two? Btw, an explanation would be more helpful than wikipedia links (gone through that, but no answer to specific query).

• How do I use an ADO.NET managed provider in Excel?

  - by Eli

  I have an ADO.NET Managed Data Provider that is registered in machine.config in DbProviderFactory - It is available for use from, say, Analysis Services, so I know it is correctly registered. However, I need to be able to query the managed provider from Excel, but the managed provider doesn't appear as a choice from Data Link Properties | All Ole Db Providers. How do I get an ADO.NET Managed Data Provider to appear there, or is there another technique I need to use? Thanks in advance, Eli.

• Database-independant SQL String Concatenation in Rails

  - by Craig Walker

  I want to do a database-side string concatenation in a Rails query, and do it in database-independent way. SQL-92 specifies double-bar (||) as the concatenation operator. Unfortunately it looks like MS SQL Server doesn't support it; it uses + instead. I'm guessing that Rails' SQL grammar abstraction has solved the db-specific operator problem already. If it does exist, how do I use it?

• Testing a Doctrine2 Entity with assertEquals results in fatal out-of-memory error

  - by Matt

  I have a PHPUnit test that's using a Doctrine2 custom repository and Doctrine Fixtures. I wanted to test that a query gave me back an expected entity from my fixture. But when I try $this->assertEquals($expectedEntity, $result);, I get Fatal error: out of memory. I'm guessing it is recursing into all the relations and the entity manager and whatnot. Is there a good way to test this equality? Should I just assertEquals on the IDs of the entities?
