railsチュートリアルの10章の10.3.3 ページネーションで
ruby
1<% provide(:title, 'All users') %> 2<h1>All users</h1> 3 4<%= will_paginate %> 5 6<ul class="users"> 7 <% @users.each do |user| %> 8 <li> 9 <%= gravatar_for user, size: 50 %> 10 <%= link_to user.name, user %> 11 </li> 12 <% end %> 13</ul> 14 15<%= will_paginate %> 16
index.html.erbに<%= will_paginate %>を入れてindexアクションも
ruby
1def index 2 @users = User.paginate(page: params[:page]) 3 end
と書き換えたのですが
ArgumentError in Users#index
wrong number of arguments (given 0, expected 1)と表示され
<%= will_paginate %>に原因があるとされどうすればいいか分かりません。
またrails consoleでUser.paginate(page: 1)と打つと User Load (3.3ms) SELECT "users".* FROM "users" LIMIT ? OFFSET ? [["LIMIT", 11], ["OFFSET", 0]]
ArgumentError: wrong number of arguments (given 0, expected 1)とエラーが表示されました
