Sphinx crossref targets for Field and it's methods are mislinked

[Gabriel Hurley]

In the howto/custom-model-fields doc, all of the methods on django.db.models.Field are linked to django.db.models, preventing any useful cross-references from being generated. Moreover, django.db.models.Field is linked as django.db.models.django.db.models.Field.

This doc needs a good bit of reST/Sphinx cleanup.
