Question

如何按时间顺序显示我的帖子？（最新到最旧）我试图在控制器的show部分添加'all.order（“created_at DESC”）。paginate（：page =＆gt; params [：page]'但是，它不起作用。有什么想法吗？我知道我在这里错过了一些非常简单的事情。提前致谢！

用户/ Show.html

<div id="posts" class="transitions-enabled">
      <% @posts.each do |post| %>

        <div class="box panel panel-default">
          <%= link_to image_tag(post.image.url(:medium)), post %>
          <div class="panel-body">
          <%= post.description %><br/>
          <strong><%= post.user.name if post.user %></strong>

          <% if post.user == current_user %>
            <div class="actions">
            <%= link_to edit_post_path(post) do %>
            <span class="glyphicon glyphicon-edit"></span>
                Edit
              <% end %>
            <%= link_to post, method: :delete, data: { confirm: 'Are you sure?' } do %>
            <span class="glyphicon glyphicon-trash"></span>
                Delete
              <% end %>
           </div>
          <% end %>
        </div>
       </div> 
   <% end %>
  </div>

用户/控制器

def index
    @users = User.paginate(page: params[:page], :per_page => 20)
  end


  def show
    @user = User.find(params[:id])

    if @user 

        @posts = @user.posts.all
        render actions: :show
    else
        render file: 'public/404', status: 404, formats: [:html]
    end  

def destroy
    User.find(params[:id]).destroy
    flash[:success] = "Your account has been deleted."
    redirect_to root_path
  end

  def correct_user
      @user = User.find(params[:id])
      redirect_to root_path 
    end

  def admin_user
      redirect_to root_path unless current_user.admin?
  end


  end
end

Answer 1

@posts = @user.posts.order("updated_at DESC")

或

 @posts = @user.posts.sort{|a,b| b.updated_at > a.updated_at}
