DjangoCon Europe 2016 - Going with the Flow with Django Admin

Speaker: Maria Lowas-Rzechonek (twitter) Django developer and involved with Django Girls.

Goals

Model workflows in Django Admin.

• Add custom workflow-related fields
• Add custom URLs
• Override default templates
• add a column to the ListView with a calculated column

Methods

• use fieldsets to separate content from workflow data
• write methods for each transition in the state model
• add get_urls(return my_urls + super_urls)
• change templates/damin/bla/keks/change_form.html to make workflow actions appear in the toolbar
• add calculated column to list
  • write method calculating the value
  • method.boolean = True for icons
  • method.admin_order_field = 'method' for ordering

  • use an annotated queryset:

    class Greater(CombinedExpression): def init__self, lhs, rhs): super(Greater, self).__init(lhs, '>', rhs, output_field=BooleanField)

    in manager: use Greater in get_queryset - add some css
