"Dynamic" form with a hidden field

This code demonstrates two simple techniques: 1. so-called "dynamic" forms, in which the form is created at run time by the model 2. using a widget (forms.widgets.HiddenInput) for a field of the form. I feel like this could be highlighted more in the documentation. You need to do something similar to get a textarea (forms.CharField(widget=forms.widgets.Textarea()) and it took me too long to figure this out. There are, no doubt, good reasons not to do what I'm doing here the way I'm doing it. Peanut gallery?

Custom Admin Redirects

This little bit of code will let you reference parts of the admin but lets you control where it returns to. For instance, I have a list of objects in the admin and i want to have a delete link for each object. I don't want them to return to the changelist after a delete however, i want them to return to my list. cheers

django-noserun for testing

I wanted to use Nose with Django so I came up with this. `TEST_RUNNER = 'noserun.run_tests'` in settings.py It does not do setup/teardown implicitly between test methods, you need to call *nosetest.test.flush()* and *nosetest.test.loaddata()* manually if you want that. Enables the method names *setup* and *teardown* The environment variable *NOSE_COVER* runs coverage tests and *NO_DROPDB* preserves the test db.

Paginator Tag for 1.x

This is a [Paginator Tag](http://www.djangosnippets.org/snippets/73/) for 1.x. Since the context is less overfull, the template, paginator.html, needs more logic. Put the tag in your templatetags and the template at the root of a template-directory. The tag will work out of the box in a generic view, other views must provide `is_paginated` set to True, `page_obj`, and `paginator`. You can get the `object_list` from the `page_obj`: `page_obj.object_list`. See [the pagination documentation](http://docs.djangoproject.com/en/1.0/topics/pagination/).

themed_template_loader

I developed this template loader for adding themes support in [gitology](http://www.amitu.com/gitology/). In order to support theming django applications, add this template loader at as the first TEMPLATE_LOADERS settings.py setting. Anywhere you request base.html, blog/index.html, when the theme is set to "bw", it will look for bw/base.html or bw/blog/index.html files first. Takes care of both render_to_response() in view or {% load template %} in templates.

Pagination shortcut

This is a function wrapping the code from [example](http://docs.djangoproject.com/en/dev/topics/pagination/#using-paginator-in-a-view) from django docs. The required parameters are: `request` which is a `Request` object from a view, and `objects` - a list of objects to paginate. You may want to tune number of items per page by specifying `count` and the name of a GET parameter through `param_name` To use it in your view just wrap the paginated object into a function for example: def someview(request): articles = Article.objects.all() ... some other logics ... return render_to_response(template, {'articles': paginate(request, articles)}

Readonly fields on Form/Modelform

A Form and ModelForm which provides the ability to specify certain fields as readonly, meaning that they will display their value as text wrapped with a <span> tag. The user is unable to edit them, and they are protected from POST data insertion attacks. The recommended usage is to place a NewMeta inner class on the form, with a readonly attribute which is a list or tuple of fields, similar to the fields and exclude attributes on the Meta inner class. class MyForm(ReadonlyForm): foo = forms.TextField() bar = forms.TextField() class NewMeta: readonly = ('foo',) Use these forms as you would a standard form in your templates.
