Yet Another Image Resizer

There's a whole range of examples online for resizing images in Django some of which are incredibly comprehensive with a wide variety of options. Here's my take on the task that serves as a simple drop in for when you don't want to include a separate app. - Only generates the resized image when first requested. - Handles maintaining proportions when specifying only a width or a height. - Makes use of PIL.ImageOps.fit for cropping without reinventing the wheel.

Formset Form

Template designers often require access to individual form fields or sets of form fields to control complex form layouts. While this is possible via looping through form fields in the template it can lead to ugly logic inside templates as well as losing the ability to use the as_* form rendering methods. This class when mixed into a form class provides hooks for template designers to access individual fields or sets of fields based on various criteria such as field name prefix or fields appearing before or after certain fields in the form, while still being able to use the as_* form rendering methods against these fields.

Template Tag Render Decorator

I often find myself needing to create a template tag and all I'm interested in is the token and the render function. This decorator abstracts away the boilerplate code around creating the template node class which is the same each and every time.

View decorator to automate templates.

Place the above code in your view, and then you can use it to specify what template to use. Set elements of the context as a dictionary and that gets passed to the template as well. For example: In view.py: #################################### @with_template('friends/index.html') def friends(request, context, username): context['user'] = User.objects.get(username = username) in friends/index.html: {% extends "base.html" %} {% block content %} <h1>{{ user.username }}'s Friends</h1>

integrated jinja2 which could use generic view ,my djangojinja2.py

I tried a few snippets of integrated jinja2 in django, which provided ?.render_to_string and ?.render_to_response in the way of jinja2. **But those snippets could not use the generic view**, because of the generic views is use default django template. so i write this snippet which could use generic view, and use the basic django.shortcuts.render_to_string, django.shortcuts.render_to_string. #in yourproject/urls.py : #install default environment is very simple djangojinja2.install() #install environment of specified Environment class from jinja2.sandbox import SandboxedEnvironment djangojinja2.install(SandboxedEnvironment) #alternative you can install sepcified environment env=Environment(...) ... djangojinja2.install(env) #something could be set in settings.py TEMPLATE_DIRS = (path.join(path.dirname(__file__),"templates"),) JINJA_GLOBALS=['myapp.myutil.foo',] JINJA_FILTERS=['django.template.defaultfilters.date',] JINJA_TESTS=('foo.mytest',) JINJA_EXTS=['jinja2.ext.i18n'] #there is no change need for app.views from django.shortcuts import render_to_response def foo(request): return render_to_response('/myjinja2.html',{'request':request}) test in django development version of r12026 , jinja2 2.2.1, python 2.5

Currency formatting filter

See the function **docstring** for usage. This template filter has a couple of drawbacks: * Uses **locale.setlocale** which, according to the [Python docs](http://docs.python.org/library/locale.html#locale.setlocale), is not thread safe. I don't know how this may affect Django applications. * Requires Python 2.5+. Updated 2011-03-16.
