I'm learning Django by building a simple recipes app. I have a 1 table model using the 'choices' field option for recipe categories rather than using a 2nd 'categories' table and a foreign key relationship. So i created db table via syncdb and then loaded table with test data. When i go to admin and click on the 'Recipes' link in an atte...
I've got a Supplier Invoice (SupplierInvoice) parent model that holds a number of orders (SupplierOrder). Right now if the user puts together an invoice via django admin, django checks to see if there are price matches for that Supplier and Product in a cost price table and pulls through the respective fields. This process happens on a...

I have a webpage which interacts with several external APIs and in order to speed things up (the speed increase is almost linear because the majority of the time is spent waiting for http responses, etc), the code is threaded so that it pulls the content from several APIs at once. The problem is, I am running into database locking presu...
I have a Django project whereby every model inherits from a common "Object" model - which defines only two fields - the ID of the object (so every object in the entire system has a unique identifier) and a "type". The type is the type of object that particular instance is. This is a sort of "denormalized" field, making it faster to trave...

I'm new to Django, but the application that I have in mind might end up having URLs that look like this: http://mysite/compare/id_1/id_2 Where "id_1" and "id_2" are identifiers of two distinct Model objects. In the handler for "compare" I'd like to asynchronously, and in parallel, query and retrieve objects id_1 and id_2. Is there a...

basically i upgraded ubuntu to juanty, and with it came python2.6 so i decided to take the chance and make django work with it. i re-svn'd django into dist-packages, and made sure to properly sym-link my admin media.

I am a Java guy and therefore would prefer a Java based framework for an auction site that I am planning to develop from scratch. But all my colleagues and friends have pointed out to me that the better sites that are coming up now-a-days are mostly written either using Ruby on Rails, Django or ASP.net MVC framework. I was wondering ...

We have a nasty problem where we see that the python logging module is behaving differently when running with mod_python on our servers. When executing the same code in the shell, or in django with the runserver command or with mod_wsgi, the behavior is correct: import logging logger = logging.getLogger('site-errors') logging.debug('log...
I'm trying to create a mapping table between two generic (content_type) references, one for "agents" and one for "resources". So I take the usual way I make a generic foreign key : content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() resource = generic.GenericForeignKey('content_type', 'object_id') ...
