Snippet List
Search results pagination
**Problem**: You search by firing POST and paginate by firing GET, so search results disappear on GET. I want to preserve searching results, so user can paginate them. First I try to use some static class to keep search results, but this solution has bug (thanks to svetlyak). In multiuser environment other user searching got results from previous one. No @cache_control(private=True) helps so I decided to change searching schema by using GET in the first place and to supply query string on each 'paging' request. Also added some memory cache that expires after 5 min **In template** Please append query to each paging link: <a href="?page={{ page_number }} &search_query={{ query|urlencode }}"> {{ page_number }}</a> This snippet should keep search results on pagination in multiuser environment.

Dynamic Form Class
Nutshell: Subclass this form with the required fields defined to automatically generate a form based on a model in a similar fashion to how form_for_model works, but in a way that tries to be a little easier if you want to customize the form. It handles updates and creations automatically as long as any database field requirements are met. This is something I made while trying to understand newforms, and is my own attempt at something between the simplicity of a stock form_for_model form, and a full blown custom form. The proper way is to use a callback function to customize form_for_model, but that felt cumbersome so I did it my way :) It works for me, but I'm relatively new to both python and Django so please test yourself before trusting.

Generate a CSV file for a model
This code generates a CSV file for a model. The URL is http://example.com/spreadsheets/app_label/model_name/ (replace spreadsheets for admin, from the URL for the model's admin page.)

Convert newlines into <p> and </p> tags
Based upon (i.e., mostly lifted from) the built-in "linebreaks" and "linebreaksbr" filters, this one works as they do: `{{ object.text|paragraphs }}`

Authenticate with Email Address
This code gives you the ability to authenticate a user by their email address instead of the username. I've also added the ability to authenticate via LDAP. Some code used from this [snippet](http://www.djangosnippets.org/snippets/74/)
- admin
- user
- authenticate
- ldap
Django Registration with GMail account
This code works with Django-registration app found here: http://code.google.com/p/django-registration/ If you plan to use this django-registrtion code in your website to allow user registration but do not run your own email server,this snippet can be handy. It uses gmail server to send out email. You have to install libgmail module first. Add two lines to your `settings.py` GMAIL_USERNAME = '[email protected]' GMAIL_PASSWORD = 'your_password' Change models.py - create_inactive_user(...) as given above

MediaWiki Markup
This is a copy paste job of mediawiki's syntax parser built in Python. You'll probably have to edit it to fit your needs MediaWiki-style markup parse(text) -- returns safe-html from wiki markup code based off of mediawiki

Subclassing a model.field for newforms
The newforms fields are more capable than the django models fields. In this snippet, we subclass models.IntegerField, and add min_value and max_value. e.g. age = MMIntegerField('How old are you?', min_value=13, max_value=120)

TestCase helpers
I use these helper methods in my unit tests. They turn many simple getting-and-posting tests into one-liners. Definitely a work in progress, and I can't be the only person who has done this sort of thing -- comments are more than welcome.

Require login across entire site
Middleware that locks down an entire site, requiring the user to login to view any page. Great for development/beta-testing.

Digg Style URL String Parser
Does a digg url effect to a string, can be useful for using an item's title in the url, from this: .hi's., is (a) $ [test], will it "work"/ \ to this: his_is_a_test_will_it_work I understand this isn't a very well made script, I am not very good at string manipulation. But I would be happy if someone would recode it in a faster, more managable way. I recomend saving the rendering.

WordWrap template tag
Basically a clone of the default "wrap" filter. I use it to generate plaintext e-mail that has to be broken at 75 characters. {% wordwrap 80 %} Some text here, including other template tags, includes, etc. {% endwordwrap %} I prefer this over the {% filter wordwrap:80 %} as my template (e-mail) writers keep screwing it up.
