Collapsed stacked inlines

A simple jQuery javascript that collapses all stacked inline rows for better handling of large inline fieldsets. It also adds "Show"/"Hide"-buttons for showing/hiding each row, which could be customized and styled using css. **Usage (see below for example):** Include the javascript on your admin page, together with jQuery, and it'll automatically affect all stacked inlines. **Developed for:** * jQuery 1.3.2 * Django trunk (tested in Django v1.0.2) * (Might work with other versions with or without adjustments, but not tested) **Use example: ** *admin.py:* class DateInline(admin.StackedInline): model = Date extra = 10 class EventAdmin(admin.ModelAdmin): inlines = [DateInline] class Media: js = ['js/jquery-1.3.2.min.js', 'js/collapsed_stacked_inlines.js',] admin.site.register(Event, EventAdmin)

This provides basic [Tenjin](http://www.kuwata-lab.com/tenjin/) integration, using a decorator. Tenjin is a blazingly fast templating system, the fastest pure-python system available. For usage and configuration, see the example in the code. I modeled this after Robert Thomson's code for Mako integration.

Custom Auth Backend to use E-Mail in Django

Instead of the default Django User the Auth Model is 'customer' from the usercp App. User's can use username as a display to the public, without disclosing their login information. This way they can use a forum with their username, which is seen by everyone. The login credentials, however are more privat, since it is the e-mail address. Allowing the user to not disclose any information.

Circular reference with Django ORM and Postgres without breaking NOT NULL FK constraints

The recipe uses deferred constraint validation to create circular references across database tables. The example requires Postgres (MySQL doesn't support deferred constraints). To achieve this, the following is required: * Insertions must be performed in a transaction. Foreign key constraints will be validated at the end of the transactions, allowing for insertion of rows with FKs pointing to rows that don't exist yet. * Primary keys need to be generated before insertion. That's what `prefetch_id` does by pulling the next value from the `*_id_seq` sequence.

Get Client IP Behind Proxy

If your application server is behind a proxy, `request.META["REMOTE_ADDR"]` will likely return the proxy server's IP, not the client's IP. The proxy server will usually provide the client's IP in the `HTTP_X_FORWARDED_FOR` header. This util function checks both headers. I use it behind Amazon's Elastic Load Balancer (ELB).
