Version 3 (modified by Adrian Holovaty, 13 years ago) (diff)

Added 'Done' note to two Roadmap elements.

The newforms-admin branch

This branch aims to integrate Django's admin site with the newforms library. Along the way, we'll take the opportunity to add extra customization hooks to the admin site, in preparation for a complete admin-site refactoring in the future.

We're aiming to get it merged into trunk by Jan. 31, 2007.

How to get the branch

svn co

See our branch policy for full information on how to use a branch.


In no particular order, here are the goals of this branch. This list may expand as we get more ideas.

  • Core goals
    • Change the admin site to use newforms instead of automatic manipulators.
    • Enable developers to declare custom widgets for particular fields in a model.
    • Enable developers to declare custom admin-only validation for a model (i.e., validation logic that is applied only in the admin site, nowhere else).
  • "Would be nice, and we're going to try our hardest to get this in" goals
    • Give developers extra hooks into the admin-site functionality. (Yes, this is a broad goal. More examples are forthcoming.)
    • Integrate some ideas from #2248: Remove core=True, specify inline models in the model itself rather than in the related model, specify which fields should be displayed inline.

The django.contrib.formtools.preview.FormPreview application (not yet documented, but fully implemented) elegantly allows for fine-grained customization of the application by subclassing. A similar approach would be a great fit for the Django admin site: Write a class that subclasses a base class called, say, ModelAdminView, and specify whichever customizations you need to make -- from the current basic admin options such as list_display and search_fields to full-on Python hooks, such as defining arbitrary Python code to run before or after a model object is saved via the admin.

We should keep in mind this future goal as we implement the newforms-admin branch. Although we don't have to implement all of this hooks for the time being, we should ensure this branch's changes are future-compatible with these plans.


Changed admin URLconf so that the five model-specific views (change_list, add_stage, history, delete_stage, change_stage) point to the class Admin in the appropriate model, rather than pointing at the django.contrib.admin view functions. Done in [4315]
Create a class django.contrib.admin.views.main.ModelAdminView, which will implement the admin hooks for a particular model. Done in [4315]
Change model infastructure/metaclass so that the inner class Admin automatically subclasses ModelAdminView. (This is a bit of black magic, but it's necessary for backwards compatibility. We may require an explicit subclass declaration in the future.) Not done
Implement ModelAdminView.add_stage, using newforms instead of the automatic manipulator. Not done
Implement ModelAdminView.change_stage, using newforms instead of the automatic manipulator. Not done
Implement ModelAdminView.change_list. Not done
Implement ModelAdminView.history. Not done
Implement ModelAdminView.delete_stage. Not done
