Filter to adjust forloop.counter across pages in a paginated view

**Update:** Never mind. See [dc's comment](http://www.djangosnippets.org/snippets/1391/#c1763) below for a much easier way to do this. I recently had to write a template for a paginated view which displayed a serial number for each `object` in the `object_list`. I normally use `forloop.counter` for general purpose serial numbers. However this did not work with paginated views as the counter gets reset in each page. This caused the serial numbers to go from 1 to #-of-results-in-the-page and then repeat. **Assumptions:** The `adjust_for_pagination` filter adjusts the value of `forloop.counter` based on the current page. `Page` and `is_paginated` variables are expected to be present in the context. These should respectively denote the current page number (1 based) and if the results are paginated. `RESULTS_PER_PAGE` is currently taken from the settings file. I couldn't think of a way to pass this value also from the template.

iPhone Redirect Middleware

I didn't really like the current state of iPhone/Mobile redirect middleware mainly because I wanted something that was closer to twitters use case. So I came up with this. I don't think it a great snippet and I will probably fix it in the near future. But it works.

monkey-patch django to use jinja2 templates for 404/500 pages and 3rd-party apps

This is heavily inspired by [http://code.google.com/p/smorgasbord/](http://code.google.com/p/smorgasbord/). But that couldn't reuse an existing jinja2 Environment, nor set filters on the Environment it created. This code assumes that you have `env` declared previously in the file as your Jinja2 Environment instance. In `settings.py`, you should set KEEP_DJANGO_TEMPLATES = ( '/django/contrib/', ) so that your Django admin still works. You can also set any other places that you do want to use Django templates there.

Custom admin widgets by field type

There are probably ways to improve the implementation, but this was something I came up with when I wanted to change the default size of all of my CharField admin fields. Now all I have to do in my ModelAdmin class is: form = get_admin_form(model) or subclass BaseAdminForm if I need extra validation or more widget customization for an individual admin form.

Testing Email Registration

http://steven.bitsetters.com/articles/2009/03/09/testing-email-registration-flows-in-django/ Testing email registration flows is typically a pain. Most of the time I just want to sign up with a test user, get the email link and finish the flow. I also want to be able to automate the whole process without having to write some SMTP code to check some mail box for the email. The best way I’ve found to do this is just to write out your emails to some file instead of actually sending them via SMTP when your testing. Below is some code to do just that. I’ve also created a Django management script that will open the last email sent out from your application, find the first link in it and open it in your web browser. Quite handy for following email registration links without logging into your email and clicking on them manually.
