Django Forms

To support creating and editing objects in Django, you’ll need to learn about Django Forms. Here are some readings to keep in mind as you progress:

• Start by learning how to work with forms in general
• Follow that up with reading about ModelForms and what they provide
• Make sure you understand form and field validation so you can ensure proper data is submitted
• Particularly complex forms, or forms which require javascript or special css, will need to utilize form assets
• You’ll want to keep a reference open for the Forms API
• Keep in mind that the custom form field you imagine may already have been created and check the Forms category on http://www.djangopackages.com
• Screencasts about Django Class-Based Views: Part 1, Part 2, and Part 3
