Kernel#send behaving strangely with ActiveRecord attribute methods

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)

=> ‘user@email.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?
