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,
