ruby-on-rails - RAILS中使用AJAX销毁微博时如何重新加载当前页面

Question

伙计们!我开始学习 RAILS。我有一个使用分页的微博列表。当我销毁微博时，它会转到第一页。但是我希望当我销毁微博时，它会重新加载当前页面。

这是我的代码:

static_pages_controller.rb

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

microposts_controller.rb

def destroy
    @micropost.destroy
    @feed_items = current_user.feed.paginate(page: params[:page])
    respond_to do |format|
      format.html { redirect_to request.referrer || root_url }
      format.js
    end
  end

销毁.js.erb

$("#microposts").html("<%= escape_javascript(render('shared/feed')) %>");

_microposts.html.erb

<% if current_user?(micropost.user) %>
      <%= link_to "Delete", micropost, remote: true,
                                       method: :delete,
                                       data: { confirm: "You sure?" } %>
    <% end %>

_micropost.html.erb

<ol class="microposts" id="microposts_profile">
  <%= render @microposts %>
</ol>
<%= will_paginate @microposts %>

你有什么想法来处理这个问题吗？

简单修复:

#app/views/microposts/destroy.js.erb
location.reload(); // Reloads current page (the :page param should be predefined from the URL)

正确修复:

#app/views/microposts/index.html.erb
<%= render @microposts %>
<%= will_paginate @microposts %>

#app/views/microposts/_micropost.html.erb
<%= link_to "Delete", micropost_path(micropost, page: params[:page]), remote: true, method: :delete, data: {confirm: "You sure?"} if current_user? == micrpost.user %>

#app/controllers/microposts_controller.rb
class MicropostsController < ApplicationController
   before_filter :authenticate
   respond_to :js, :html

   def index
      @microposts = current_user.feed.paginate
   end

   def destroy
      @micropost = Micropost.find params[:id]          
      @microposts = current_user.feed.paginate(page: params[:page]) if @micropost.destroy
   end

   private

   def authenticate
      return unless logged_in?
   end
end

这将允许您更新以下内容:

#app/views/microposts/destroy.js.erb
$("#microposts").html("<%=j render @microposts %>");
