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.

Authenticate with Email Address

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

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.

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.

Better render_to_response

I'm finding this much more efficient (from a coding perspective) than using the `render_to_response` shortcut. It looks complex, but it's simple to use: just look at the example in the docstring. Call this script `renderer.py` and chuck it in your project root.

{% with %} template tag

Add a value to the context (inside of this block) for easy access. Provides a way to stay DRYer in your templates. **NOTE:** This tag is now in Django core, so if you have Django >0.96 (or SVN) then you do NOT need this.
