Question

我试图在单个视图中显示current_user帖子以及他或她关注帖子的用户。无论出于何种原因，我已经创建的帖子都没有加载到视图中。目前数据库中有5个。

def feed
  following_ids = current_user.following_users.map(&:id)
  @following_activities = Post.where('user_id in (?)', following_ids.push).order('created_at desc').paginate(page: params[:page])
end

feed.html.erb

  <% if @following_activities.any? %>
      <% @following_activities.each do |user| %>
          <%= link_to(image_tag(user.post.avatar.url(:thumb), style: 'text-decoration: none;', class: 'round-image'), user_path(user)) %>
          <%= user.post.username %>
          <%= user.post.body %>
          <%= image_tag(user.post.photo.url(:medium), style: '') %>
      <% end %>
  <% else %>
      <h1>No new posts</h1>
  <% end %>

Answer 1

似乎你没有向id数组推送任何东西，你应该推current_user.id。您可以使代码略微清晰，如：

user_ids = current_user.following_users.pluck(:id).push(current_user.id)
@following_activities = Post.where(user_id: user_ids).order('created_at desc').paginate(page: params[:page])

Answer 2

通过三个步骤，我能够将两者结合起来，现在它正常运作。

def feed
    following_ids = current_user.following_users.map(&:id)
    following_ids << current_user.id
    @following_activities = Post.where(user_id: following_ids).order("created_at desc").paginate(page: params[:page])
end
