Edc custom django ModelAdmin mixins, tags and templates

Overrides ModelAdmin's get_form to insert question numbers and the DB field names.

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]"

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.

Redirects the admin form on save to a view other than the default changelist if post_url_on_delete_name is set.

@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:

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:

@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.
