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

Why not use @dummy.save_without_validation method to skip validations altogether? I prefer do something like this:

if @dummy.valid?
  @dummy.save # no problem saving a valid record
else
  if @dummy.errors.size == 1 and @dummy.errors.on(:field)
    # skip validations b/c we have exactly one error and it is the validation that we want to skip
    @dummy.save_without_validation 
  end
end

You could put this code in your model or in the controller, depending on your needs.
