Group assignment when adding a user to django-admin

Question

In my application, I have models that have a Users model as a foreign key, for example:

class Doctor(models.Model): username=models.ForeignKey(User, unique=True) ... 

In the admin site, when adding a new doctor, I have the opportunity to add a new user next to the username field. This is exactly what I want, but in the dialog that opens, it asks for the username and password for the new user; I would also like to be able to assign a group to this new user. What would be the best way to do this?

Thanks lokharkey

In your application, create "admin.py", where you will actually register your own model for the administrator, add the following code.

 from django.contrib.auth.models import User from django.contrib.auth.admin import UserAdmin from django.contrib.auth.forms import UserCreationForm class MyUserCreationForm(UserCreationForm): """ A form that overrides the UserCreationForm """ class Meta: model = User fields = ("username", "groups") UserAdmin.add_form = MyUserCreationForm admin.site.register(Doctor) 

Now you just need to override the template that displays this overridden form. Create a directory structure like,

 "your_project_root_directory"/templates/admin/auth/user/add_form.html 

and copy the contents as

 {% extends "admin/change_form.html" %} {% load i18n %} {% block after_field_sets %} <p>{% trans "First, enter a username and password. Then, you'll be able to edit more user options." %}</p> <fieldset class="module aligned"> <div class="form-row"> {{ form.username.errors }} {# TODO: get required class on label_tag #} <label for="id_username" class="required">{% trans 'Username' %}:</label> {{ form.username }} <p class="help">{{ form.username.help_text }}</p> </div> <div class="form-row"> {{ form.password1.errors }} {# TODO: get required class on label_tag #} <label for="id_password1" class="required">{% trans 'Password' %}:</label> {{ form.password1 }} </div> <div class="form-row"> {{ form.password2.errors }} {# TODO: get required class on label_tag #} <label for="id_password2" class="required">{% trans 'Password (again)' %}:</label> {{ form.password2 }} <p class="help">{% trans 'Enter the same password as above, for verification.' %}</p> </div> <div class="form-row"> {{ form.groups.errors }} {# TODO: get required class on label_tag #} <label for="id_groups" class="required">{% trans 'Groups' %}:</label> {{ form.groups }} <p class="help">{% trans 'All existing Groups listed here. If you are not seeing any group, means you dont have any groups object created.' %}</p> </div> <script type="text/javascript">document.getElementById("id_username").focus();</script> </fieldset> {% endblock %} 

And you are good to go. Its working fragment.

Just out of curiosity, is this type of solution considered kosher in Django? That is, it seems to copy / paste a large piece of code, as it does against the DRY principle that Django developers are touting.
