How to add extra parameter to resources in routes

routes, ruby-on-rails

Solution

`resources` method doesn't allow you to do that. But you can do something similar using the `path` option and including extra parameters:

resources :users, path: "users/:another_param"

That will generate urls like this:

users/:another_param/:id
users/:another_param/:id/edit

In this case you will need to send `:another_param` value to routing helpers manually:

edit_user_path(@user, another_param: "another_value")
# => "/users/another_value/#{@user.id}/edit"

Passing `:another_param` value is not required if a default value has been set:

resources :users, path: "users/:another_param", defaults: {another_param: "default_value"}

edit_user_path(@user) # => "/users/default_value/#{@user.id}/edit"

Or you can even make the extra parameter not mandatory in the path:

resources :users, path: "users/(:another_param)"

edit_user_path(@user) # => "/users/#{@user.id}/edit"

edit_user_path(@user, another_param: "another_value")
# => "/users/another_value/#{@user.id}/edit"

# The same can be achieved by setting default value as empty string:
resources :users, path: "users/:another_param", defaults: {another_param: ""}

If you need extra parameters for particular actions, it can be done this way:

 resources :users, only: [:index, :new, :create]
 # adding extra parameter for member actions only
 resources :users, path: "users/:another_param/", only: [:show, :edit, :update, :destroy]

Problem

I want member routes generating by `resources` to contain additional parameter. Something like: ``` resources :users ``` with folowing routes: ``` users/:id/:another_param users/:id/:another_param/edit ``` Any ideas ?
