Question

很抱歉重复，经过大量搜索，我无法找到问题的答案。 {_ 1}}调用后，will_paginate无效。

删除操作后，它根本不显示页码（只返回所有结果）。
搜索操作后，页码不会更新，显示的页面数量应超过实际应用的页数。

这是控制器代码。

Ajax

这是索引视图：

class CitiesController < ApplicationController

 def index
     @cities = City.get_cities(params[:city_name],params[:city_population]).paginate(:page => params[:page])
  respond_to do |format|
    format.html 
    format.js
  end

 end

 def create
      @city = City.new(params[:city])

  if @city.save
       flash[:success] = "City information saved successfully"

       redirect_to cities_path
    else
        render 'index'
    end
 end


def new
    @city = City.new
end


 def destroy
   @city = City.find(params[:id]).destroy
   @city.destroy
   @cities = City.all
   respond_to do |format|
      format.html {redirect_to cities_path}
      format.js
    end
  end

 end

以下是该表的局部视图：

 <div class="row">
<h1>Search Cities or <%= link_to "Create New City", new_city_path %></h1>
<h3>99 random city information are generated in the database </h2>
<h3>Simply type any letter or city population between 0 and 10 to filter out</h3>
<%= form_tag "/cities/index", method: :get, remote: true do %>
  <%= label_tag(:q, "City Name:") %>
  <%= text_field_tag 'city_name' %>
  <%= label_tag(:q, "City Population greater than, in units of 1 million:") %>
  <%= text_field_tag 'city_population' %>
  <label></label>
  <%= button_tag("Search", :class => "btn") %>
<% end %>
<% flash.each do |key, value| %>
   <div class="alert alert-<%= key %>"><%= value %></div>
<% end %>


<div id='table' class="table table-striped">
    <%= render 'table' %> 
</div>


<%=will_paginate @cities %>
 </div>

Answer 1

自己找到解决方案。

将<%= will_paginate @cities %>添加到部分文件

中

并将@cities = City.all更改为

@cities = City.all.paginate（页面：params [：page]）

因为will_paginate不期望array个对象。

写入您的控制器

def index
  @cities = City.get_cities(params[:city_name],params[:city_population]).paginate(:page => params[:page])
  respond_to do |format|
   format.html 
   format.js  
  end 
end

在您的视图文件夹中创建index.js.erb并写入

$('id or class').html('<%=escape_javascript render :partial => which part you update %>')

Rails：AJAX调用后，Will_paginate无法正常工作
