XX. Generating HTML forms from models
|
|
|
|
This is mostly just a reworking of the ``form_for_model``/``form_for_instance``
|
|
tests to use ``ModelForm``. As such, the text may not make sense in all cases,
|
|
and the examples are probably a poor fit for the ``ModelForm`` syntax. In other
|
|
words, most of these tests should be rewritten.
