edc-model-admin
---------------
Edc custom django ModelAdmin mixins, tags and templates
ModelAdminFormAutoNumberMixin
+++++++++++++++++++++++++++++
Overrides ModelAdmin's ``get_form`` to insert question numbers and the DB field names.
ModelAdminNextUrlRedirectMixin
++++++++++++++++++++++++++++++
Skips the ``changelist`` and redirects to the next CRF or Requisition listed in an edc visit schedule if "[Save and Next]"
is clicked instead of "[SAVE]"
.. code-block:: python
class BaseModelAdmin:
search_fields = ("subject_identifier",)
add_form_template = "edc_model_admin/admin/change_form.html"
change_form_template = "edc_model_admin/admin/change_form.html"
change_list_template = "edc_model_admin/admin/change_list.html"
@admin.register(CrfTwo)
class CrfTwoAdmin(BaseModelAdmin, ModelAdminNextUrlRedirectMixin, admin.ModelAdmin):
show_save_next = True
show_cancel = True
You need to use the included ``change_form.html`` to override the submit buttons on the ``admin`` form.
See also:: ``edc_visit_schedule``
ModelAdminRedirectOnDeleteMixin
+++++++++++++++++++++++++++++++
Redirects the admin form on save to a view other than the default ``changelist`` if ``post_url_on_delete_name`` is set.
.. code-block:: python
@admin.register(CrfFive)
class CrfFiveAdmin(ModelAdminRedirectOnDeleteMixin, admin.ModelAdmin):
post_url_on_delete_name = "dashboard2_app:dashboard_url"
def post_url_on_delete_kwargs(self, request, obj):
return {'subject_identifier': obj.subject_identifier}
You can also store url names in the request object if used together with the Middleware from ``edc_dashboard`` and ``edc_subject_dashboard``.
This is useful if you do not know the namespace until deployment.
For example, add to settings:
.. code-block:: python
MIDDLEWARE=[
...,
'edc_dashboard.middleware.DashboardMiddleware',
'edc_subject_dashboard.middleware.DashboardMiddleware',
],
DASHBOARD_URL_NAMES={
'subject_dashboard_url': 'dashboard_app:subject_dashboard_url',
},
and then declare the model admin class:
.. code-block:: python
@admin.register(CrfFive)
class CrfFiveAdmin(ModelAdminRedirectOnDeleteMixin, admin.ModelAdmin):
post_url_on_delete_name = "subject_dashboard_url"
def post_url_on_delete_kwargs(self, request, obj):
return {'subject_identifier': obj.subject_identifier}
``ModelAdminRedirectOnDeleteMixin`` will attempt to get the urlname from the request object using ``post_url_on_delete_name`` as a dictionary key.
