Ruby on Rails 资源#index 缺少请求格式的模板：text/html

Question

while trying to familiarize with using resources for planning routes, I encountered a weird error:

No template for interactive request

ShoppersController#index is missing a template for request formats: text/html

Here are the routes mapping

routes.rb

Rails.application.routes.draw do
 resources :shoppers 
end

shoppers_controller.rb

class ShoppersController < ApplicationController

  def index 
  end

  def create
    @shopper = Shopper.new
  end

end

shoppers.html.erb

<h1>Welcome Shoppers</h1>

Does anyone know how to solve this?

Thanks for all the feedbacks you share.

Answer 1

It's because the name of your view is wrong. As the error you're getting says: 'Rails expects an action to render a template with the same name contained in a folder named after its controller'

So in your case, the structure needs to be:

• app
  • controllers
    • shoppers_controller.rb
  • views
    • shoppers
      • index.html.erb
      • new.html.erb

Answer 2

Create a view with the name of the action in the controller!
