Stripe: ActionController::UrlGenerationError | No route matches | missing required keys: [:id]

问题

I am just learning RoR and need I am having trouble with Stripe integration. I have done everything as it says here except I have changed "charges" to "charge."

The error I am receiving is: No route matches {:action=>"show", :controller=>"charge"} missing required keys: [:id].

It's not letting me do: <%= form_tag charge_path do %>

This is my controller:

class ChargeController < ApplicationController
def new
end

def create

# Amount in cents
@amount = 0

customer = Stripe::Customer.create(
:email => 'jon@jonkhaykin.com',
:card  => params[:stripeToken]
)

charge = Stripe::Charge.create(
:customer    => customer.id,
:amount      => @amount,
:description => 'Inspire App Charge',
:currency    => 'usd'
)

rescue Stripe::CardError => e
flash[:error] = e.message
redirect_to charge_path
end
end

My routes.rb file has: resources :charge

Thank you for your help!

You should not divert from Rails standards, that will most of the time punish you for it. You should rename your controller back to ChargesController and take a look at "Singular Resources" on how you can solve your issue.

So the changes that you need to fix your issues are as follows:

Rename app/controllers/charge_controller.rb to app/controllers/charges_controller.rb
Rename class ChargeController to class ChargesController
Replace resources :charge with resource :charge

By replaceing resources :charge with resource :charge you will be creating a singular charge resource with the path /charge.

With your current setup i.e. resources :charge you will see the following (which is not what you want):

charge_index   GET    /charge(.:format)              charge#index
               POST   /charge(.:format)              charge#create
new_charge     GET    /charge/new(.:format)          charge#new
edit_charge    GET    /charge/:id/edit(.:format)     charge#edit
charge         GET    /charge/:id(.:format)          charge#show
               PUT    /charge/:id(.:format)          charge#update
               DELETE /charge/:id(.:format)          charge#destroy

As you can see above the charge_path resolves to charge#show but if you look at the path it also requires an :id parameter which you are not supplying in your form_tag :charge_path call.

You need to change your controller name to ChargesController, change the path helper to charges_path and the routes to resources :charges.

Also, the form should be POSTing.
