Validation that works in the controller

Rails
1

Hi,

Is there a way of validating input inside the controller? or an
equivalent to
ActiveRecord::Validations::ClassMethods.validates_presence_of ?

Cheers,

just override the validate method

class Foo < ActiveRecord::Base
def validate
errors.add(:name, “is blank”) if name.nil? or name == “”
# other validations
end
end

then you can call @user.valid? at any time

I have a Rails Weenie tip for validating non-model data. It basically
creates a table-less model you can use for a form:
