Autogenerate admin classes in admin.py

Tired of adding admin classes to admin.py whenever you add a model? This admin.py automatically keeps itself up-to-date with your models.py file. It assumes if you have a model: MyModel, you want an admin class called AdminMyModel. Regards, Luke Miller

auto image field w/ prepopulate_from & default

Given such code: class ProductImage(models.Model): fullsize = models.ImageField(upload_to= "products/%Y/%m/%d/") display = AutoImageField(upload_to= "products/%Y/%m/%d/",prepopulate_from='fullsize', size=(300, 300)) thumbnail = AutoImageField(upload_to="products/%Y/%m/%d/",null=True,default='/media/noimage.jpg')) display will be automatically resized from fullsize, and thumbnail will default to /media/noimage.jpg if no image is uploaded Note: At some point the code broke against trunk, which has now been updated to work properly

Automatic stripping textual form fields

Here is a class decorator that allows not to bother with stripping leading and trailing white space from user input provided via forms. This could be a temporary solution for an issue addressed in the ticket [#6362](http://code.djangoproject.com/ticket/6362). The documentation is provided in the form of doctest. The decorator works with `ModelForm`'s just as well as with ordinary forms. Note however that this is not a 100% panacea. Your models still could become malformed if theirs data is obtained from another source, not forms.

Smarter USPhoneNumberField

The original USPhoneNumberField only validates xxx-xxx-xxxx values. This field validates... > (xxx) xxx xxxx > xxx-xxx-xxxx > (xxx)-xxx-xxxx > many others. **Explanation of the regular expression:** 1. Accepts either (xxx) or xxx at the start of the value. 2. Allows for any amount of dashes and spaces (including none) before the next set of digits. 3. Accepts 3 digits 4. Allows for any amount of dashes and spaces (including none) before the next set of digits. 5. Accepts 4 digits, finishing the value. This field saves in the same format that the original USPhoneNumberField does (xxx-xxx-xxxx). Enjoy!

RefreshSessionMiddleware

This middleware refreshes the session before it expires to avoid dropping the session of an active (but read-only) user. By default it refreshes the session after half the expiry time has elapsed. (This middleware does nothing for browser-length sessions.)

isUnique validator for newforms

This is a generic unique field value validator for use with newforms. ( It's handy to plug into newforms-admin.) Example, with newforms-admin: ` class LinkAdminForm( ModelForm ): def clean_url( self ): return isUnique( self.instance, 'url', self.cleaned_data['url']) class LinkAdmin( ModelAdmin ): form = LinkAdminForm site.register( Link, LinkAdmin ) `

PermanentRedirectMiddleware

This is a simple middleware that redirects the exactly URL requested with the correct domain. It is useful when you have more than one domain (most of cases with "www." or IP) to access a website. To make it works, download the snippet file as the name "permanent_redirect.py" and add its path as the first item in MIDDLEWARE_CLASSES setting in settings.py. Later you must inform a setting called `HTTP_HOST_DOMAIN` with the correct domain.

Translated choices fields

- Choices are saved as the key integers. - Admin will show the correct translation in forms. - You can reuse the make_choices function for other choices fields. - Bad side: bin/make_messages.py won't get the choices values automatically, you have to add them in the .po's by hand.

Parse TemplateTag Variables Safely

Often times I want to be able to interchangeably pass either literal strings or context variables to a custom templatetag. This function first checks a string for the existence of surrounding quotes and uses the string inside. If the string didn't explicitly use quotes it checks to see if it can resolve the string as a context variable. As a fallback the function will simply return the full string. Example: {% get_latest_by_tag 'django' %} {% get_latest_by_tag object.tag %}
