Ruby 在 Rails 上没有为 Controller 创建视图

Question

I'm definitely very new to Ruby on Rails. I created a new rails folder like this:

Edit: Sorry for the inconvienience, but I did use the --api tag.

rails new <project-name> -d mysql --api

since I use mysql instead of sqlite . Then, in the tutorial they used a command like this:

rails generate controller Welcome index

I did the exact same thing, however in the log it shows this:

   create  app/controllers/welcome_controller.rb
   route  get 'welcome/index'

It didn't seem to create the view. I don't know why it's doing this. After I start the server with rails server I can go to the localhost:3000/welcome/index but it just takes me back to the home page, and in the log it says Started GET.... No Content... . So it couldn't find the view. How can I fix this?

Answer 1

Unless you created an API only project with the --api flag, the rails generate controller Welcome index command should have created an index.html.erb file in the views folder.

You can either delete the welcome_controller.rb file and the generated line from the route.rb file and run the command again or you can manually create the view with the touch command (assuming your OS supports the touch command):

touch app/views/welcome/index.html.erb

or through you favourite text editor or IDE. On a side note, controller names should be plural ( WelcomePagesController for example).
