Rails 4 - will_paginate

[英]Rails 4 - will_paginate

This is my first attempt using will_paginate (I know! Where have I been??) 这是我第一次尝试使用will_paginate(我知道!我去过哪里了?)

titles_controller.erb titles_controller.erb

  def index
    @titles = Title.active.sorted.paginate(:page => params[:page])
  end

index.html.erb index.html.erb

<% will_paginate @titles.each do |title| %>

Error: 错误:

undefined method `total_pages' for #<Enumerator:0x00000002bacaf0>

WTF am I doing wrong? WTF我做错了吗? Thanks in advance. 提前致谢。

Please read will paginate docs . 请阅读paginate docs You need to write: 你需要写:

<%= will_paginate @posts %>

There is no need for adding each . 无需添加each

So entire view would look like: 所以整个视图看起来像:

<% @titles.each do |title| %>
  <!-- do smth with title -->
<% end %>

<%= will_paginate @titles %>

In your case you dont acctually need to write: 在你的情况下,你不需要写:

<%= will_paginate @titles %>

Because it is in the context of the title_controller, will_paginate will assume their is a @titles variable available. 因为它位于title_controller的上下文中,所以will_paginate将假设它们是一个可用的@titles变量。 Thus it is possible to just write: 因此可以写:

<%= will_paginate %>
