[Rails] Problems with master-detail relationship
I have two tables. Let say headers and details. On headers_controller.rb I have has_many :details On details_controller.rb I have belongs_to :header I have in my model for header (just for testing): def list @headers = Headers.sort( headers.kind ASC) end So when i run after loading the proper data a header.details.size it returns me the number of details for the selected header. But when I try to display header.details.size in a list view for the headers I get an arror saying Unrecognized constant Header::Detail I try to get this in the list with: %= header.details.size % What am I doing wrong? -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.
