django-snippets

Django app containing a few useful snippets and tools for reducing boilerplate code:

• For Django Admin:

  • a mixin that allows format strings to be used for list_display e.g. list_display = ('id', ('amount', '{:.2f} EUR'), ('interest', '{:.2%}'))
  • a PercentField that stores percentages on 0-1 scale but displays them in admin as 0-100% with a '%' suffix
  • tweaks for inputs that display a given prefix/suffix (e.g. '%' or 'GBP')
  • build_admin_models: a method for automatically generating most admin model classes, using mixins on models where necessary to overide features
  • a Next/Previous button for viewing models (use NextPreviousAdminMixin - used automatically if you use build_admin_models)

• For Django Models:

  • a "at least one not null" Mixin for model clean form
  • an AddedByMixin
  • a UniqueNameModel

• urls:

  • model instance to admin changeform url

• widgets:

  • read only value/foreign key widgets

• forms:

  • workaround for ensuring "extra" fields on a ModelForm are preserved in "initial" when using modelformset_factory

• caching:

  • a basic hierarchical cache implementation

Note that "django-snippets" should be included in your Django project's "INSTALLED_APPS"
