Class Form
This class uses the member variable "constraints" as a list to store
elements of type class Field. The form then represents a form of
user input controls, perhaps an HTML form. Add fields to this class,
call the validate() method and let the magic begin.
It is expected that you will usually just subclass this class and modify
self.constraints at that time. Obviously you don't need to do
this.
Setting up rules is done when you add a Field and is documented there

(Constructor)

isValid(self)
Call this after doing a validate(). Returns true if the form is
100% valid and false otherwise
-
|
validate(self,
values)
The main magic worker. Loops over each of the field elements stored
in self.constraints and calls its validate() method. Takes
the results returned by the validation and updates its results dict.
Returns a dictionary containing all of the fields we validated,
indexed by field name.
