Question

I am trying to get custom routes based on the username rather than the ID. I have it working to get to the show page of the user but I am also trying to nest the resources so that I can see his posts and comments using the same syntax.

Example:

Works… “mysite.com/users/username/”

Does not work… “mysite.com/users/username/posts/”

routes.rb

...
# Users with the Username...
match 'users/:username' => "users#show" do
    get :posts
    get :comments
end

# Users with the ID...
resources :users do
    get :posts
    get :comments
end
...

Answer 1

Perhaps you can use the to_param method and update your nested routes/resources:

routes.rb:

resources :users do
    resources :posts
    resources :comments
end

user.rb

class User < ActiveRecord::Base
  def to_param
   username
  end
end

..for finds in the UserController:

 @user = User.find_by_username(params[:id])

(or any variation of finding by the username criteria)
