Measures when model cannot be created

I am creating an application with Ruby on rails, and when I did rails g model hoge (model name), I could not make a model for some reason, so I will write the cause and solution.

error contents

The result is as follows.

The name Diary means that it cannot be used because it is already in use. Since the application name was diary, I thought that I should change it, so I changed the folder name. After making the change, I did rails g model diary again ...

I got the exact same error: sweat:

Conclusion

You need to change the application name in the config file.

before

app/config/application.rb

module Diary ← The application name is displayed here
  class Application < Rails::Application
    config.load_defaults 6.0
  end
end

after

app/config/application.rb

module EveryDiary ← Change
  class Application < Rails::Application
    config.load_defaults 6.0
  end
end

By changing the name, I was able to create a model safely! I felt that I also needed to check the config file.
