A Django application that makes user creation of form fields simple, handling everything from form generation to data storage and retrieval.

This was initially built for `MUN Manager <https://modelun.co>`_ to allow conferences to collect whatever information they wanted to during all parts of the registration process. django-user-fields allows conferences to easily add their own extra fields to various forms using a simple admin interface creating a tailored experience.

Simple Installation and Usage Guide
===================================

1. Install ``django-user-fields``:

.. code-block::

    $ pip install django-user-fields

2. Add ``user_fields`` to your installed apps:

.. code-block::

    INSTALLED_APPS = (
        ...
        'user_fields',
        ...
    )

3. Run a database migration:

.. code-block::

    $ python manage.py migrate

4. Create an ``ExtendedExtraField`` model:

.. code-block::

    from user_fields.models import ExtraField

    class ExtendedExtraField(ExtraField):

        # You can add any custom fields you'd like here to make filtering fields easier.
        # A list of all predefined fields can be found below.

5. Add the ``@initialise_extra_fields`` decorator to your form:

.. code-block::

    from user_fields.decorators import initialise_extra_fields

    @initialise_extra_fields
    class ExampleForm(forms.ModelForm):

6. Add the ``UserFieldMixin`` to the object(s) you would like to have extra fields:

.. code-block::

    from user_fields.mixins import UserFieldMixin

    class ExampleObject(models.Model, UserFieldMixin):

7. Add a ``UserDataField`` to the object for storage and migrate:

.. code-block::

    from user_fields.models import UserDataField, ExtraField

    class ExampleObject(models.Model, UserFieldMixin):

        extra_data = UserDataField()

    $ python manage.py migrate

**Note**: If ``extra_data`` is taken and/or you would like to name the storage field something else, you can define ``USER_FIELDS_ATTR_NAME`` in your settings.

8. Create and pass some extra fields to your form:

.. code-block::

    extra_fields = ExtendedExtraField.objects.filter(parameter=something)

    form = ExampleForm(... extra_fields=extra_fields, ...)

9. Add an extra line to save the extra fields to your object:

.. code-block::

    object = form.save()
    object.save_extra_form_data(form) # Ensures that both object and form save functions are not overwritten.

Supported Fields
================

- ``CharField``
- ``CharField With Choices``
- ``TextField``
- ``BooleanField``
- ``EmailField``

Feel free to submit a pull request if you would like to add more fields. Most fields should be relatively easy to add, although ``FileField`` will be an interesting challenge!
