Field limitation/filtering in model

on 9/14/13, 4:52 AM 959 views

Hello everyone! I'm new in OpenERP (just a few days) and I would like to create a simple model with 2 fields: "name" (text) and "age"(integer)

  • name - is required and can contain string not longer than 20 symbols - it's easy
  • age - is required and should contain integer greater or equal than 20

My question is - how I can verify or check imput values for field "age"?

Thanks a lot!

There are lots of ways you can go for.

  1. You have to override create and write method and in that method you can check whether value of age is greater than or equal to 20. You may find many examples about how to override create and write methods.
  2. Best way is to define a custom constraint on that field.

For ex:

def _check_age(self,  cr,  uid, ids, context=None):
    obj = self.browse(cr, uid, ids[0], context=context)
    if obj.your_age_field < 20:
        return False
    return True
_constraints = [(_check_age, 'Age must be greater than or equal to 20.', ['your_age_field']),]

Hope this will help you.

Thanks! Now I understend better how openerp works!
