Hello, I'm programming a database front end. In many cases I want to constrain the data written to the database. Therefore I implement some checks either through real database constraints or trough some logic in the model, so it will throw an exception when the constraints are not met.
e.g.: unique constraint on a database column. Now, when I write my form validation, I have to implement the same logic again, since form validation takes place before a save() is even considered. Like this: >>> if form.is_valid(): >>> form.save() Is there a better way to do it? Is there a good way to avoid this duplicate logic?
