IsNullFieldListFilter

As the title does a pretty good job of condensing, this is a subclass of `FieldListFilter` for the Django 1.4 Admin system which allows you filter by whether a field is or is not `NULL`. For example, if you had an `Author` model and wanted to filter it by whether authors were also users of the site, you could add this to your `AuthorAdmin` class: list_filter = ( ('user_acct', IsNullFieldListFilter), ) For the record, it began life as a modified version of `BooleanFieldListFilter` from `django.contrib.admin.filters`.

drupal7 password check

Completely based on [snippet 2729](http://djangosnippets.org/snippets/2729/) (see that snippet for useful comments!). The above snippet did not work for me (something with MemoryError), so I looked at the Drula source code and reimplemented...

add port from settings file to an url

I'm working on a Project where on certain places I need absolute URL's, in development mode I need the port 8000 added to any absolute url. This piece of work, took me some time to figure out. Couldn't find something similiar on the net, it's based on Code from the Python urlparse module. You can change the "settings.PORT" part to "settings.DEBUG == True" if you like, and so on. META: replace parameters in URL, edit parameters in URL, edit URL, urlparse

Admin page without inlines dinamically

Sometimes the related objects needs that the main object exists in order to edit and save them properly. There are two main solutions: override the ModelAdmin.add_view() view or remove the inlines only from the add view page (and not from the change page). The former requires a lot of coding, the latter it's impossible without patching Django because the inlines are not dynamic. **This simple solution hides the inline formsets only from the add page, and not from the change page.** Adding an "if" structure it is possible to choose the inlines to use. Example use case: when a related inline model have to save a file to a path that needs the ID key of the main model, this solution prevent the user to use the related inline model until the model it's saved. Tested on Django-1.4, should work since Django-1.2.

SELECT FOR UPDATE in Django < 1.4

SELECT FOR UPDATE, which does row-level locking in the database, was added by Django only in version 1.4. This snippet emulates that feature in older versions of Django. Tested in Django 1.2, but should work in newer versions as well. select_related is removed because it causes errors when used with RawQuerySet.

Routing urls.py By Convention

No more entries in urls.py... This is the simple version of a central controller for an app that routes requests by names, thus keeping you from adding a line into urls.py for every, single, page. Assuming your app name is "account", add the following to your urls.py file: (r'^account/(?P<path>.*)\.dj(?P<urlparams>/.*)?$', 'account.views.route_request' ) The URL /account/mypage.dj will be routed directly to account.views.py -> process_request__mypage(request, parameters). You can read more about this on [my blog](http://warp.byu.edu/site/content/1100).

True Unique Boolean Model Decorator

This class decorator will help you when you want to keep a unique boolean (think a 'default' field which should only be only one set to true in a group). The interesting thing with this, is that it's possible to assign a subset of fields to be used, so that the uniqueness of the field will be guaranteed among only the subset (look at the Example section in the code to understand this behaviour). This is a better and improved way of doing http://djangosnippets.org/snippets/2676/
