one to many asscoaiation

I have an account and an account can have many creditcards, for example. So I have my models set as:

class Account < ActiveRecord::Base   has_many :creditcards end

and

class Creditcards < ActiveRecord::Base   belongs_to :account end

Now, in an .rhtml file I am trying to say something like this:

<% if @account.creditcards.count > 0 %>   Code to display all creditcards asscociated with this account <% end %>

Instead what I see is this error:

undefined method `creditcards' for "156429":String

I keep on looking at my code and I can't see anything wrong. Isn't this the correct way to set up a one-to-many relationship? Thanks,

Your setup seems to be ok.

But the error:

undefined method `creditcards' for "156429":String

says that @account is a string containing "156429". (maybe the id of the record) Anyway, the error is most likely in your find, please post the code that assigns @account

That was it! I had @account = params[:id] instead of @account = Account.find_by_id(params[:id]). Thanks for the help,
