has value in a console but it's nil in my controller and my view?

I have this strange behavior and I don’t undertand why. Here is the thing:

I have this record in my payment model:

1.9.3p286 :019 > u.payment.  last
Payment Load (0.3ms)  SELECT "payments".* FROM "payments" WHERE "payments"."user_id" = 10
 => [#<Payment id: 37, bank_name: "Mercantil", plan: "Plan Uno", date: "2012-12-25", reference_number: "3452435", coupon: "", user_id: 10, created_at: "2012-12-25 21:56:12", updated_at: "2012-12-25 21:58:31", active_until: "2013-01-24">]

As you can see, I have one record for my user: 10.

If I try to get the same information in my controller I don’t get any exception, but

@user.payment.last.active_until

is empty, the same in the view.

For example if I try this in my view:

<%= @user.payment.last.active_until %>

I didn’t get anything, is blank.

If I try this

<%= @user.payment %>

I got the same as my console

[#<Payment id: 37, bank_name: "Mercantil", plan: "Plan Uno", date: "2012-12-25", reference_number: "3452435", coupon: "", user_id: 10, created_at: "2012-12-25 21:56:12", updated_at: "2012-12-25 21:58:31", active_until: "2013-01-24">, #<Payment id: nil, bank_name: nil, plan: nil, date: nil, reference_number: nil, coupon: nil, user_id: 10, created_at: nil, updated_at: nil, active_until: nil>]

I really don’t understand what happend here. Any help please.

Thanks in advance.

PD: The user could has many payments, but I need just the last.

it seem some code create one nil record, maybe in controller

notice the payment id in console is 37, and in view, you get that record but not the last one

A quick style note - if a User record has many Payment objects, the naming convention is to use the plural form - so the association in User would be ‘has_many :payments’, not ‘has_many :payment’. Not related to the problem here, but fixing it will make the code easier to read for other developers.

I got the same as my console

[#<Payment id: 37, bank_name: "Mercantil", plan: "Plan Uno", date: "2012-12-25", reference_number: "3452435", coupon: "", user_id: 10, created_at: "2012-12-25 21:56:12", updated_at: "2012-12-25 21:58:31", active_until: "2013-01-24">, #<Payment id: nil, bank_name: nil, plan: nil, date: nil, reference_number: nil, coupon: nil, user_id: 10, created_at: nil, updated_at: nil, active_until: nil>]

Actually you didn’t get the same as in console - there’s that extra record with all fields set to nil. Does your controller call ‘@user.payment.build’ someplace?
