Question

Supposing I have 3 tables: Users, Roles and UserRoles. I can fetch the user_roles in the request: users/1/user_roles but what if I want to fetch the roles of a user such as: users/1/roles.

My relation is as follows:

has_many :roles, :through => :user_roles

Is it possible?

Answer 1

The relation in your model has no direct relevance to the url you go to. You need to replicate your existing behaviour for routes rather than user_routes by either adding a new action or new controller and creating new views etc.

At the moment you probably have either:

• an action called user_routes in the UsersController
• an action called index in the UserRoutesController

So either:

• Add an action called routes in the UsersController
• Add an controller called RoutesController with an index action.

Regardless to which method you are using, in your action set your instance variable to user.roles instead of user.user_roles.

You can then write whatever view code you need.
