Question

我在RoR 5.2中安装了我的应用，但收到错误消息：

ArgumentError in StaticPages#home
wrong number of arguments (given 0, expected 1)

此代码错误的第一行出现：

<% if @feed_items.any? %>
  <ol class="microposts">
    <%= render @feed_items %>
  </ol>
  <%= will_paginate @feed_items %>
<% end %>

当我转到“主页”页面时出现此错误，并且代码在这里：

<div class="col-md-8">
  <h3>Micropost Feed</h3>
  <%= render 'shared/feed' %>
</div>

我也在我的项目目录中搜索了涉及此实例变量'@feed_items'的项目，它位于此处：

static_pages控制器：

      def home
        if logged_in?
          @micropost  = current_user.microposts.build
          @feed_items = current_user.feed.paginate(page: params[:page])
        end
      end

microposts_contoller

     def create
        @micropost = current_user.microposts.build(micropost_params)
        if @micropost.save
          flash[:success] = "Micropost created!"
          redirect_to root_url
        else
          @feed_items = []
          render 'static_pages/home'
        end
      end

此处完全错误：

ActionView::Template::Error (wrong number of arguments (given 0, expected 1)):
    1: <% if @feed_items.any? %>
    2:   <ol class="microposts">
    3:     <%= render @feed_items %>
    4:   </ol>
