Question

我正在使用'public_activity'gem来创建活动Feed。我跟着this tutorial

本教程向您介绍如何为关注某些人的用户创建活动Feed。

class ActivitiesController < ApplicationController
  def index
    @activities = PublicActivity::Activity.order("created_at desc").where(owner_id: current_user.followed_user_ids, owner_type: "User")
  end

...

如何添加current_user的id，以便在索引页面上看到他跟随的人加上他自己的活动？

Answer 1

您可以创建另一个变量并将其放在索引视图中的@activities变量之前吗？

这样的东西就是控制器：

class ActivitiesController < ApplicationController
  def index
@activities_current_user = PublicActivity::Activity.order("created_at desc").where(owner_id: current_user.id, owner_type: "User")
@activities = PublicActivity::Activity.order("created_at desc").where(owner_id: current_user.followed_user_ids, owner_type: "User")
  end

然后在视图中：

<% @activities_current_user.each do |activity| %>
  <div class="activity">
    <%= link_to activity.owner.name, activity.owner if activity.owner %>
    <%= render_activity activity %>
  </div>
<% end %>

<% @activities.each do |activity| %>
  <div class="activity">
    <%= link_to activity.owner.name, activity.owner if activity.owner %>
    <%= render_activity activity %>
  </div>
<% end %>
