Rails，更改控制器内POST操作的URL

Question

I want the URL to be changed when a call to an action within the controller is made. My current scenario:

Controller:

class EventController < ApplicationController
    def index 
        if city.blank?
            failure
        end
        ...
    end

    def failure
        ...
        render 'failure'
    end
end

Routes:

get '/event', to: 'event#index'
post '/event/failure' => 'event#failure'

But this code keeps the url as /events. The desired result is /events/failure

I've views for payment 'index' and 'failure'. I'm using rails ~ 5.0.0.

For the URL to change you will want to do a redirect, something like this :

class EventController < ApplicationController
    def index 
        if city.blank?
            redirect_to action: 'failure'
        end
        ...
    end

    def failure
        ...
        render 'failure'
    end
end

But, redirection is not possible for POST requests as given in HTTP/1.1

You might want to consider changing your strategy.
