Question

I am trying to use namespaces to declare an api.

My routes.rb contains:

  devise_scope :user do
    namespace :api do
      namespace :v1 do
        match 'log_in', :to => 'token_authentications#log_in', :via => "post"
      end
    end
  end

And my *token_authentications_controller.rb* looks like this:

class Api::V1::TokenAuthenticationsController < ApplicationController

...

  def log_in

  ...

  end

...

end

When I hit: api/v1/log_in I get:

Routing Error
uninitialized constant Api

So do I need to declare the namespace somewhere?

Answer 1

Rails expects namespaces to follow directory structure, unless I’m mistaken.

Given your class name for your controller, Api::V1::TokenAuthenticationsController, rails expects it to live in app/controllers/api/v1/token_authentications_controller.rb.

If you just move your controller to the correct folder, I think you should be fine.

You might also want to make sure to actually declare the namespace modules somewhere, like for instance refactoring your controller as such:

module Api
  module V1
    class TokenAuthenticationsController

...

    end
  end
end
