ルーティング（route.rb）について
以下のroutes.rbに対するルーティングを
app/routes.rb
Rails.application.routes.draw do
devise_for :users, controllers: {
sessions: 'users/sessions',
registrations: 'users/registrations',
}
# For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html
root 'homes#top'
get 'mypage', to: 'homes#about'
# For details on the DSL available within this file, see https://guides.rubyonrails.org/routing.html
end
以下のコマンドでどのようなルーティングとなっているか確認しましょう。
$ rails routes

viewについて
まず、users下にできるviewファイルには以下があります。
homes
top.html.erb
about.html.erb
自分はファイル名を mypage -> about に変更してます。users
confirmations/new.html.erb
mailer/confirmation_instructions.html.erb
mailer/email_changed.html.erb
mailer/password_change.html.erb
mailer/reset_password_instructions.html.erb
mailer/unlock_instructions.html.erb
passwords/edit.html.erb
passwords/new.html.erb
registrations/edit.html.erb
registrations/new.html.erb
sessions/new.html.erb

新規登録の動作
1.1.
localhost:3000に接続
1.2.
routes.rbの
root GET / homes#top
を参照して home_controller.rbのtop -> views/homes/top.html.erbを表示する。
1.3.
新規登録をクリック
1.4.
top.html.erbの<%= link_to '新規登録', new_user_registration_path %>によって、routes.rbの以下の行を参照して
new_user_registration GET /users/sign_up(.:format) users/registrations#new
users/regstrations_controller.rbにnewがないので、何も実行せずにusers/registrations/new.html.erbを表示。
1.5.
name,email,password,確認用passwordを入力して新規登録をクリック。
1.6.
<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
この部分は調べてもわからなかった。また今度詳しく調べる。
1.7.
DBに入力した情報が登録されてmypage.html.erbを表示する。
