Show Notes

Big News (1:37)

• Official Django 1.0 Announcement
  • Version 1.0 Roadmap
  • Original Proposal on Google Groups

EuroPython Django Sprint –
We are holding an official Django sprint, July 10th until saturday July 12th, during the EuroPython conference. Join us in the push to 1.0.

Tracking Trunk (9:19)

• Fixed serialization for multi-model inheritance (7600)
  • Serializers were including all superclass fields in their output. Now only local fields are included.
  • Implicit OneToOne? primary keys were not correctly added to the metamodel, so they were always marked to be serialized, even though they were primary
  • Model saving was too aggressive about creating new parent class instances during deserialization. Raw save on a model now skips saving of the parent class.

• Prevent update on sliced queryset (7601) – Update doesn’t reliably support limit and offset.

• Added an —exclude option to dumpdata (7615) – This makes it possible to exclude a particular application from the output.

• Corrected empty QuerySet.values call when combined with extra (7636)

• Abstracted some more database options into DatabaseFeatures (7643) – This makes it easier to control behavior through the database backend.

• Added list_display Admin options to FlatPage (7651)

• Improved fixture error reporting (7653) – It now displays the entire traceback.

Branching and Merging (17:06)

• newforms-admin is now trunk feature compatible.
  • Implemented save_as functionality. This also properly makes inlines work as well. (7603)
  • Implemented max_num on formsets and model formsets. Added a hook on InlineModelAdmin to customize in the admin interface. (7613)
  • Implemented ModelAdmin.radio_fields to match trunk’s radio_admin. (7626)

• Improvements to the ModelAdmin API.
  • Added ability to pass extra_context argument to ModelAdmin’s add_view, change_view, changelist_view, delete_view and history_view methods. (7627)
    • This makes it easier to customise those pages; you can over-ride the methods in your subclass and call the super method with extra_context to feed additional variables to your custom admin templates.
  • Made it easier to specify a custom template to be used in the admin section. (7630)
    • You can now specify index_template and login_template properties on an AdminSite subclass, and change_form_template, change_list_template, object_history_template and delete_confirmation_template properties on a ModelAdmin subclass.

• Formsets API is now finalized. Documentation was committed for formsets. (7606)

• Initial admin documentation is now available (7616) and (7617).
  • Watch for changes to newforms-admin documentation.

Community Catchup (29:58)

• Callcast – Discussion with Eric Florenzano – Nice interview by Kevin Fricovsky with Eric Florenzano. A little raw but enjoyable.

• Django Dash Results – Congratulations to all the participants. Check the results for information on all the winners.
  • 1st Place – Benjamin Pollack and Tyler Hicks-Wright – Their site was a code review site with Mercurial integration.
  • 2nd Place – Eric Florenzano and Tony Hauber – Feedalizer is a syndication feed aggregation based on popular feeds ranked by users.
  • 3rd Place – Justin Lilly and Jannis Leidel – A site connecting developers & translators with rankings for translators and groupings.

• A Better Serialization Framework – A series of interesting posts by fiam on creating what he calls a better serialization framework.
  • Part 1
  • Part 2
  • Part 3

• DebugFooter middleware with Pygments sql syntax highlighting – In a never-ending quest to create the ultimate debug footer, Andreas Marr has created yet another version.
  • django-logging

• js-forms – Jonathan Buchanan has been busy porting newforms to Javascript.

Tip of the Week (41:59)

If you have a template tag that you want to automatically load into context for all of your templates, you can take the same approach Django does with the built-in template tags.

This must be done early on in the load process, so in your <i>init</i>.py for the app or project, just do:

from django.template import add_to_builtins
add_to_builtins('template_utils.templatetags.generic_content')

• django-template-utils – James Bennett’s excellent template utilities

Thank You! (44:56)

  • Firebug Extension – excellent for Javascript debugging.
  • Webkit – Open source rendering engine used in Safari.

• Django-SQLAlchemy
