Forms in Django allow encapsulating form data and validation logic. This document discusses advanced form techniques in Django, including: - Dynamically generating forms based on models to handle multiple forms of different types. - Altering form fields dynamically based on request data, such as restricting a dropdown to related objects owned by the user. - Fully dynamic form building by defining form fields from database models, such as a survey application where questions are defined in models. - Common techniques like subclassing form methods, type() function to dynamically generate form classes, and leveraging standard Python to extend Django's capabilities.
