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]”

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.

ModelAdminRedirectOnDeleteMixin

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.

Template themes

You can change the default theme colors.

EDC_MODEL_ADMIN_CSS_THEME = "edc_indigo"

Options are:

• edc_indigo

• edc_deep_purple

• edc_purple

ModelForm Save Delay

You can configure the save buttons on the CRF and PRN model forms to disable for a few seconds after clicked by the user.

# settings.py
EDC_MODEL_ADMIN_SAVE_DELAY = 3000 # delay for 3 seconds

The default is 0 seconds.

Where internet connections are slow a user may think they did not click the save button and click it again. This may lead to multiple submissions of the same form and raise an IntegrityError. Save delay disables the button for 3 seonds (or as configured) to minimize the chance of this type of error occuring.
