Description

GenUpdate and GenUpdateModal are generic classes of Cdenerix used to generate a form automatically that handle the task of editing objects and their validation. Is recomended that the name of each class which inherit from GenUpdate or GenUpdateModal follow this pattern: NameModel+Update or NameModel+UpdateModal respectively. Both GenUpdate and GenUpdateModal usually are created at the same time.

• Example:

  If model is User, then, GenUpdate declarations should be, class UserUpdate(GenUpdate):

  If model is User, then, GenUpdateModal declarations should be, class UserUpdateModal(GenUpdateModal):
