Rebar makes your Django Forms stronger.
Rebar is a collection of tools that make it easier to work with Django forms and develop more complex abstractions. Rebar includes:
Form Groups
Treat a heterogeneous set of Forms or FormSets as a single logical Form.
State Validators
Validate that a Form is in a particular state. For some applications you want to allow users to save their work, even if they haven't completed the task. State Validators allow you to abstract the validation for specific states.
Testing Tools
Easily generate dictionaries of form data from a Form, FormSet, and FormGroup instances for use in unit tests.
Rebar supports Django 1.5 and later on Python 2.6, 2.7, and 3.3.
