How to remove validation using instance_eval clause in Rails?

Question

I would like to enhance existing class using instance_eval. There original definition contains validation, which require presence of certain fields, ie:

class Du         


        

Answer 1

This does not directly answer the question but here's an option you should consider in such a situation: instead of disabling validation, you could set the required fields in a before_validation hook.

Since you don't need those required fields, set them with some dummy data that satisfies the validation and forget about them.

No ugly monkey patching.
