后台内容添加和展示
一、添加入口
二、添加访问接口
// 分类管理首页
router.get('/content',function(req,res,next){
var page=Number(req.query.page||1);
var limit=10;
var totalpages=0;
Content.count().then(function(count){
totalpages=Math.ceil(count/limit);
page=Math.min(page,totalpages);
page=Math.max(page,1);
var skip=(page-1)*limit;
// 降序排序
Content.find().sort({_id:-1}).limit(limit).skip(skip).then(function(contents){
console.log("文章内容: "+contents);
res.render('admin/content.html',{
userInfo:req.userInfo,
contents:contents,
page:page,
limit:limit,
count:count,
totalpages:totalpages,
});
})
})
}); 三、添加内容页面
{% extends 'moban.html' %}
{% block main %}
<!--面包屑导航-->
<br>
<ul class="breadcrumb">
<li><a href="/admin" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" >管理首页</a></li>
<li><span>内容管理</span></li>
</ul>
<!-- 操作列表 -->
<hr>
<button type="button" class="btn btn-info">编辑</button>
<button type="button" class="btn btn-primary" onclick='window.open("/admin/content/add")'>添加</button>
<button type="button" class="btn btn-danger">删除</button>
<button type="button" class="btn btn-danger">批量删除</button>
<!--表格内容-->
<h1>内容管理</h1>
<table class="table table-striped table-hover table-responsive">
<thead>
<tr>
<th>ID</th>
<th>标题</th>
<th>分类</th>
<th>简介</th>
<th>内容</th>
</tr>
</thead>
<tbody>
{% for content in contents %}
<tr>
<td>{{content._id.toString()}}</td>
<td>{{content.title}}</td>
<td>{{content.category.id.toString()}}</td>
<td>{{content.description}}</td>
<td>{{content.content.slice(0,30)+"........"}}</td>
</tr>
{% endfor %}
</tbody>
</table>
<!-- 分页 -->
<br>
<br>
<ul class="pager">
<li id="frontpage"><a href="/admin/content?page={{page-1}}" target="_blank" rel="external nofollow" >上一页</a></li>
<li> 第{{page}}页，共{{totalpages}}页;每页显示{{limit}}条数据，共{{count}}条数据 </li>
<li id="nextpage"><a href="/admin/content/?page={{page+1}}" target="_blank" rel="external nofollow" >下一页</a></li>
</ul>
{% endblock %} 四 、添加内容添加访问接口
// 内容添加
router.get('/content/add',function(req,res,next){
Category.find().then(function(categories){
res.render('admin/content_add.html',{categories:categories});
})
}); 五、添加内容添加页面
{% extends 'moban.html' %}
{% block main %}
<!--面包屑导航-->
<br>
<ul class="breadcrumb">
<li><a href="/admin" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" >管理首页</a></li>
<li><a href="/admin/content" target="_blank" rel="external nofollow" >内容管理</a></li>
<li><span>内容添加</span></li>
</ul>
<!--表格内容-->
<br>
<h1>内容添加</h1>
<hr>
<div class="container">
<div class="row clearfix">
<div class="col-md-12 column">
<form class="form-horizontal" role="form" method="POST" action="/admin/content/add">
<div class="form-group">
<label for="inputEmail3" class="col-sm-2 control-label">标题</label>
<div class="col-sm-10">
<input type="text" class="form-control" name="title" id="inputEmail3" />
</div>
</div>
<div class="form-group">
<label for="inputPassword3" class="col-sm-2 control-label">简介</label>
<div class="col-sm-10">
<textarea class="form-control" name="description" rows="3"></textarea>
</div>
</div>
<div class="form-group">
<label for="inputPassword3" class="col-sm-2 control-label">内容</label>
<div class="col-sm-10">
<textarea class="form-control" name="content" rows="7"></textarea>
</div>
</div>
<div class="form-group">
<label for="inputPassword3" class="col-sm-2 control-label">选择分类</label>
<div class="col-sm-10">
<select class="form-control" name="category">
{% for category in categories %}
<option value="{{category._id.toString()}}">{{category.categoryName}}</option>
{% endfor %}
</select>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default">提交</button>
</div>
</div>
</form>
{% if msg %}
<div class="alert alert-warning">
<a href="#" target="_blank" rel="external nofollow" class="close" data-dismiss="alert">
×
</a>
<strong>结果:</strong>{{msg}}
</div>
{% endif %}
</div>
</div>
</div>
<!-- 分页 -->
<br>
<br>
<!-- 通过包含来使用模板 -->
{% include 'page.html' %}
{% endblock %} 六、添加内容提交接口
// 内容提交
router.post('/content/add',function(req,res,next){
if(req.body.title==""||req.body.description==""||req.body.category=="")
{
var msg="必须输入!"
res.render('admin/content_add.html',{msg:msg});
}
else
{
new Content({
title:req.body.title,
description:req.body.description,
content:req.body.content,
category:req.body.category
}).save().then(function(re){
var msg="内容提交成功";
res.render('admin/content_add.html',{msg:msg});
})
}
}); 七、添加数据模型
///shemas/content.js
var mongoose=require('mongoose');
module.exports= new mongoose.Schema({
title:String,
// 分类的ID-关联字符
category:
{
// 类型
type:mongoose.Schema.Types.ObjectId,
// 引用
ref:"centent"
},
description:
{
type:String ,
default:''
},
content:
{
type:String ,
default:''
}
}) ///modules/Conten.js
var mongoose=require('mongoose');
var contentSchema=require('../schemas/content');
module.exports= mongoose.model('Content',contentSchema); 七、结果
