How can I use CSRF protection with WTForms and Pyramid?
In flask, there's a WTForms module which handles this.
What would be a way to have this with Pyramid as well without creating spaghetti code implemented in main logic and with all forms?
CSRF protection in WTForms is handled by subclasses of class SecureForm. You should implement a subclass of SecureForm that uses Pyramid's facilities to store tokens in user session and to obtain tokens as they come with a request for verification.
A good implementation to follow is the one for Flask, in flask.ext.wtf.Form class. This is a small class that should port to Pyramid without much effort.
