Document newforms field types which handle relationships

[empty]

It seems that some aggressive cut and pasting in the interest of ModelForms removed the ModelChoiceField information entirely from the newforms documentation. It's still possible to use a non model based form but have choice information pulled from a lookup table. I think either this information should be re-included in newforms documentation or at least a reference to the ModelForms documentation included.

I had a look at the changeset:
​http://code.djangoproject.com/changeset/6844

I couldn't find documentation of ModelChoiceField in the old version (red) that was not in the
new version (green).

Please reopen this ticket if you still think something is missing.

The actual problem is that it was never part of the newforms docs themselves; it was always covered as part of the docs for helpers that generated forms. I'm re-titling this ticket to note that fact.
