Now I have 3 models, item category and sub-category and 3 Tables in my database.
I planed to set the association like this. Item Belongs_to :category Belongs_to :sub-category category Has_many :items Has_many :sub_category sub_category belongs_to :category Has_many :items And now I want to have some dynamic drop down list in the items/new page When I chose one category, and the sub-category will dynamically updated. what other move do I need? Is that right? It makes me feel confused with these associations. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
