Re: Is the DoesNotExist exception the only way to check if an object exists?

This can work when you know you want to use the object once it's been retrieved. If all you want to do is check for existence then it's better to do the check with a: if Class.objects.filter(pk=pk).count() == 0: # Do object doesn't exist stuff else: # Do object does exist stuff -- G On

I'm a bit of a noob as well, and know nothing about Rails, but I'd like to comment on a few issues you mentioned. 1. Non-existent template variables are replaced with the value of the TEMPLATE_STRING_IF_INVALID setting. Set that to something besides its default (an empty string) to make

Dynamic forms through a class factory; 'string index out of range'

As the title suggests, I'm creating a dynamic form via a class factory. Here is what I'm doing inside the class factory itself (as far as actually making the class goes): class _QuestionAnswerForm(forms.Form): response =

Re: Dynamic forms through a class factory; 'string index out of range'

Honestly, I really don't like that method, mostly due to ugliness. I'm looking for a solution specifically to instantiating a form created via a class factory, unless that is some sort of Herculean task. On Apr 10, 10:13 am, Daniel Roseman wrote: > On Apr 10, 4:40 pm,

Re: Dynamic forms through a class factory; 'string index out of range'
