django_select2_autofill

django_select2_autofill is a Django app that allows newly added Django admin inline form autocomplete fields to be automatically filled with data from the last user-selected option of the same autocomplete field in a form produced by a shared formset.

This allows end-users to more efficiently input new data in instances where one value may be shared across ModelAdmin formset form autocomplete fields.

Install

1. With a Django project virtual environment activated:

   python -m pip install django-select2-autofill

2. Add django_select2_autofill to your Django INSTALLED_APPS setting:

   INSTALLED_APPS = [
      # ...
      "django_select2_autofill",
   ]

3. Use the AutofillAutocompleteSelect widget in the ModelForm containing autocomplete_fields:

   from django import admin, forms
   from django_select2_autofill import AutofillAutocompleteSelect
   
   
   class CustomForm(forms.ModelForm):
       class Meta:
           widgets = {
               "model_field_name": AutofillAutocompleteSelect(
                   CustomModel.model_field_name.field, admin.site
               ),
           }

   Note that admin.site can be replaced with a custom AdminSite instance, if necessary:

   # ...
   from app.admin import CustomAdminSite
   
   
   # ...
   widgets = {
       "model_field_name": AutofillAutocompleteSelect(
           CustomModel.model_field_name.field, CustomAdminSite()
       ),
   }
