No route matches [POST] OmniAuth Steam Callback

Question

I'm building Rails API for AngularJS app. I'm using devise_token_auth and omniauth-steam gems. When I try to authenticate user using the Steam there is an error:

ActionController::RoutingError (No route matches [POST] "/omniauth/steam/callback"

I've added devise_token_auth routes, but they don't create POST callbacks. I've tried to manually create POST route for callback, but it hasn't worked and I'm not sure if it is even correct solution. I'm trying to solve this problem from yesterday and I can't find anyone with the similar one.

config/routes.rb

Rails.application.routes.draw do
  namespace 'api' do
    namespace 'v1' do
      mount_devise_token_auth_for 'Api::V1::User', at: 'auth'
    end
  end
end

config/initializers/omniauth.rb

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :steam, ENV['steam_api_key']
end

I use figaro gem and save steam_api_key in application.yml file.

rake routes task

                                       GET    /omniauth/:provider/callback(.:format)    devise_token_auth/omniauth_callbacks#redirect_callbacks

                                       GET    /api/v1/auth/:provider(.:format)          redirect(301)

I know that it's a bit messy because of namespaces, but it shouldn't cause this problem, right?

EDIT: I did some research and here is the link https://github.com/lynndylanhurley/devise_token_auth#usage-tldr it says that /:provider/callback url should have GET/POST action, but as we can see I don't have POST action for callback.

Answer 1

Finally I've solved this problem by adding below line to the routes.rb file.

post '/omniauth/steam/callback', to: 'overrides/omniauth_callbacks#redirect_callbacks'

I've created omniauth_callbacks_controller.rb file in controllers/overrides folder and removed below line.

skip_before_action :set_user_by_token, raise: false

The last step was editing line with redirect route. I've changed this:

redirect_route = "#{request.protocol}#{request.host_with_port}/#{Devise.mappings[devise_mapping].fullpath}/#{params[:provider]}/callback"

To hard-coded route.

redirect_route = "/api/v1/auth/steam/callback"
