Hi,
I''m developing a app with dynamic field using hstore ( postgres ).
The app works great, but now, i''m trying to implement validations.
my code is:
#model
..
def initialize_custom_fields
class_eval do
validates field.f, :presence => true
end
end
..
#user controller
def create
user = User.new
user.initialize_custom_fields
user.attributes = params[:user]
user.save
end
The first time I press "save" button, the validations works as well,
but
the second one i''m getting this error:
undefined local variable or method `_callback_before_170045'' for
#<User:0x007f80f9990558>
Anyone have a idea for solution this error.. ?
Thanks,
Diego
