从 gem 继承控制器类

Question

I am using the ShopifyApp gem, which has an action called receive in its WebhooksController . As seen here: Webhooks controller

In my WebhooksController controller I am trying to override that receive action by doing the following:

class WebhooksController < ShopifyApp::WebhooksController
  def receive
    binding.pry
  end
end

My route to my WebhooksController is this:

webhooks_receive POST   /webhooks/receive(.:format)  webhooks#receive

And the route put in by the Gem engine is:

webhooks POST /webhooks/:type(.:format)  shopify_app/webhooks#receive

I see the data come in, but for some reason its not hitting my receive action and stopping at my pry and I'm not sure why.

Found this and tried it, but no luck.

I tried this solution too and it didn't work..

Any thoughts?

Here are the top of my logs showing what's happening:

And my routes file

Rails.application.routes.draw do
root :to => 'home#index'
mount ShopifyApp::Engine, at: '/'
resources :store
resources :shipping_methods

post '/webhooks/receive', to: 'webhooks#receive'
post '/billing_plans', to: 'billing_plans#save_plan', as: 'save_plan'
get '/activate_charge', to: 'billing_plans#activate_charge', as: 'activate'
post '/create_charge', to: 'billing_plans#create_charge', as: 
'create_billing_plan'

Answer 1

After two days of troubleshooting I realized their Gemspec was including an old version of rails that did not contain the method they were calling..

I let them know and bumped my version from 4.2.5 to 4.2.6 and now it works.. frustrating but solved.. thanks everyone for your support!

If anyone else comes across this, in order to use the Shopify App gem Webhooks controller you will need to be running Rails 4.2.6.

Try putting routes in this order:

post '/webhooks/receive', to: 'webhooks#receive'
mount ShopifyApp::Engine, at: '/'

Answer 3

Rails routes are matched in the order they are specified, so if you have a resources :photos above a get 'photos/poll' the show action's route for the resources line will be matched before the get line. To fix this, move the get line above the resources line so that it is matched first.

So in order for your own route to take precedence over the one that is defined in the ShopifyApp gem, you need to define it before mounting the ShopifyApp engine.

Moving your own route post '/webhooks/receive', to: 'webhooks#receive' before mount ShopifyApp::Engine, at: '/' should fix the issue.
