ContentType template filter

Custom template filter to retrieve a content type of a given model instance. Useful for ModelForms which want to set the content_type field (i.e: GenericForeignKey). ### A usage example: {% load helpers %} {% with instance|content_type as ctype %} <input type="hidden" name="content_type" value="{{ ctype.pk }}"> {% endwith %} Original idea from [this stackoverflow answer] [1] [1]: http://stackoverflow.com/a/12807458/484127

Fix for the bad behaviour of GenericForeignKey field

I don't know if you noticed but GenericForeignKey behaves badly in some situations. Particularly if you assign a not yet saved object (without pk) to this field then you save this object the fk_field does not get updated (even upon saving the model)- it's updated only upon assigning object to the field. So you have to save the related object prior to even **assigning** it to this field. It's get even more apparent when you have null=True on the fk/ct_fields, because then the null constrains won't stop you from saving an invalid object. By invalid I mean an object (based on a model with GFK field) which has ct_field set but fk_field=None. Maybe this problem is irrelevant in most use case scenarios but this behaviour certainly isn't logical and can introduce silent bugs to your code.

URL models

You can use `UrlModel` to provide URL functionality to any instance of any model and any language (language support can be removed from this). Each model must have own view method, that returns HttpResponse. I was inspired by Flatpages. It is useful for small sites and static pages. `class Page(UrlModel): text = models.TextField() def view(self, request) # do something here return HttpResponse(...)`

Improved model select field for generic relationships

Browse through the installed models using the content types framework. There are two difference in behavior with respect to the default field: 1. if a model provides a translation for its name (e.g.: verbose_name and/or verbose_name_plural), it shows that rather than a raw model name 2. allow to filter the models shown through the use of `choice` parameter Example: `mbf = ModelBrowseField(choices=['User', 'Session'])`
