I'm going through an weird behavior with Kernel#send and *I think* it might be related to ActiveRecord (I'm using Rails 2.3.11). I have a User model that has the following fields: email: String status: Integer (among others) If I do: some_arg_that_might_come_in_a_local_var = true method = 'email' @user.send(method,some_arg_that_might_come_in_a_local_var) => 'email@example.com' So, email doesn't expect the additional var (it's an AR accessor AFAIK, so it should not accept any args), but it doesn't throw the ArgumentError exception. The some_arg_that_might_come_in_local_var is an argument that will be passed to certain methods that DO accept a second boolean argument, but it happens that sometimes the method argument sent to send can be email or status. But if I do: some_arg_that_might_come_in_a_local_var = true @user.send(method,some_arg_that_might_come_in_a_local_var) ArgumentError: wrong number of arguments (1 for 0) I then get the exception. Any ideas? Cheers, - Marcelo.
