二、业务流程

- 用户登录

- 预定会议室

- 退订会议室

- 选择日期;今日以及以后日期

三、表结构设计

- 用户表

- 会议室表

- 记录表

用户ID 会议室ID 时间 时间段

from django.db import models  # Create your models here. class MeetingRoom(models.Model):     '''会议室'''     name = models.CharField(max_length=32,verbose_name="会议室名称")     class Meta:         verbose_name_plural = "会议室"      def __str__(self):         return self.name  class ReserveRecord(models.Model):     '''预定记录表'''     data = models.DateField(verbose_name="预定日期")     user = models.ForeignKey(to="UserInfo",verbose_name="预订人")     room = models.ForeignKey(to="MeetingRoom",verbose_name="预定房间")     time1 = (         (1,"8.00"),         (2,"9.00"),         (3,"10.00"),         (4,"11.00"),         (5,"12.00"),         (6,"13.00"),         (7,"14.00"),         (8,"15.00"),         (9,"16.00"),         (10,"17.00"),         (11,"18.00"),         (12,"19.00"),         (13,"20.00"),     )     timeline = models.IntegerField(choices=time1,verbose_name="预定时间")     class Meta:         verbose_name_plural = "预订记录表"         unique_together = (             ('data', 'timeline', 'room')         )     def __str__(self):         return self.user.username  class UserInfo(models.Model):     '''用户信息'''     username = models.CharField(max_length=32,verbose_name="用户名",unique=True)     password = models.CharField(max_length=64,verbose_name="密码")     class Meta:         verbose_name_plural = "用户信息"      def __str__(self):         return self.username


四、操作细节以及设计的知识点

=========================后端页面=================

我们可以用ajax的方式,发送请求。后端返回数据,直接在页面中渲染。

如何生成这样的数据

data = [

[{"text":"天上人间","attrs":{}},{"text":"海燕","attrs":{"room_id":1,"time_id":1,"class":"chosen"}},{"text":"","attrs":{"room_id":1,"time_id":1}},{"text":"","attrs":{"room_id":1,"time_id":1}},{"text":"","attrs":{"room_id":1,"time_id":1}}],

[{"text":"夏威夷","attrs":{}},{"text":"","attrs":{"room_id":2,"time_id":2}},{"text":"Frank","attrs":{"room_id":1,"time_id":1,"class":"chosen"}}],

[{"text":"马尔代夫","attrs":{}},{"text":"","attrs":{"room_id":3,"time_id":3}},{"text":"","attrs":{"room_id":1,"time_id":1}}],

]


有可能有人已经预定了,当没有chosen的时候就没有预定.

预定信息都放在预定表里了

所以我们得去预定表里面取一些数据

那么怎么获取预定信息呢?获取指定日期所有的预定信息(也就是这一天的所有预定信息)

具体操作:

在数据库里面添加预定信息

到底查那天的是不确定的,应该是用户给发过来的,所以发ajax的时候得发过来一个日期

data:{choice_data:"2017-5-5"}

在views中,获取日期,但是这个日期是有限制的,必须是大于等于当前的日期,如果是前几天的就不能在选,都已经过去了,

当前日期等于....data类型

获取的日期等于...str类型。所以要转一下。


获取到的是一个queryset集合[

OBJ(1,room_id,user_id.time_id.data)

OBJ(1,room_id,user_id.time_id.data)

OBJ(1,room_id,user_id.time_id.data)

]

检测会议室在该时间段是否已预定

在上面这个数据存在则表示已经预定,不存在没预定

方式一:

利用两层循环来做,但是循环的效率不怎么高,所以也可以用结构化数据的方式


for bk in recording_list:         if room.id==bk.room.id and bk.timeline==tm[0]:             td={"text":bk.user.username,"attrs":{"room_id":room.id,"time_id":tm[0],"class":"chosen"}}                    # 如果没有预定就不加     tr.append(td)


下面是具体操作

View Code

吧[

OBJ(1,room_id,user_id.time_id.data)

OBJ(1,room_id,user_id.time_id.data)

OBJ(1,room_id,user_id.time_id.data)

]变成一个字典

查询中字典的查询速度是最快的

{

  2: {

    9: {'username': 'egon', 'user_id': 1}

  }

}

1表示room_id,5表示time_id


ecrding_dict = {}
for i in recording_list:
if i.room_id not in recrding_dict:
recrding_dict[i.room_id]={i.timeline:{"username":i.user.username,"user_id":i.user_id}}
else:
recrding_dict[i.room_id][i.timeline] = {i.timeline:{"username":i.user.username,"user_id":i.user_id}}
print(recrding_dict)


然后看一下它的room_id和time_id在不在字典里面。如果在里面已经被预定了,否则没有被预定

具体实现

前端页面


======================前端页面===================== 今天日期怎么获取、: d = new Date()   #当天日期 d.getFullYeat()  #年 d.getMonth()   #月 d.getDate()    #日 =========给字符串扩展的一个uuuu方法============ String.prototype.uuuu = function(){     return "zzzz" } =========给日期对象扩展的一个Format方法============ d = new Date() Date.prototype.Format = function(){     .. }    ===============加载框================= 和模态框一样,也有两层(遮罩层,加载层) .shade {             position: fixed;             z-index: 1040;             top: 0;             left: 0;             right: 0;             bottom: 0;             background-color: #999;             filter: alpha(opacity=50);             -moz-opacity: 0.5;             opacity: 0.5;         }          .loading {             position: fixed;             z-index: 1050;             top: 40%;             left: 50%;             height: 32px;             width: 32px;             margin: 0 0 0 -16px;             background: url(/static/img/loading.gif);         }  那么什么时候让他显示呢? 默认是隐藏的 当刚开始发ajax的时候加载,获取成功之后就让隐藏了 出错之后也给让加载    解决forbidden  function csrfSafeMethod(method) {         // these HTTP methods do not require CSRF protection         return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));     }     $.ajaxSetup({         beforeSend: function (xhr, settings) {             if (!csrfSafeMethod(settings.type) && !this.crossDomain) {                 xhr.setRequestHeader("X-CSRFToken", $.cookie('csrftoken'));             }         }     });

待续具体操作、、、、、、、、、、


绑定完以后预定或者退订

  1、预定的时候加个样式,当点完以后取消预定给移除了

  2、如果是本来就有的,先把有的背景去掉,而且文本清空

  3、点击保存吧选中的以及取消过的都发到后台,

    我要预定那些,我要取消那些。要把这些数据发送过去

    我们通过样式发过去有点麻烦,我们可以通过一个全局变量发过去

    POST——DATA = {

      "ADD":{},

      "DEL":{}

    }

    假如:

    POST——DATA = {

    "ADD":{

      room_id time_id

        4: [4,5]

      },

    "DEL":{}

    }

    现在来生成这样的结构,如果4存在。

    js中的{}对象如果key存在,就有值,如果不存在返回undified



  4、当一开始预定了,然后又不预定给删除了,这时的数据没有在数据库中,从add中吧数据删除

  5、js中的删除指定的值,   v= [1,2,3,4]

              v.indexOf(3) #找到就找到,找不到就等于-1

              当找到的时候用v.splice(index,1) #删除索引位置的一个


  6、增加的id有他,删除的id也有他,先删除还是先增加?

      POST——DATA = {

        "ADD":{

          1:[5,6]

          2:[5,6,7]

        },

        "DEL":{

          1:[6,7]

          }

        }

    先删除后添加,因为这是还没有数据库呢。原来数据库就已经有有值了,先从add,和del中删除了,数据库就不用再添加了。

    完了批量添加其他的值


  7、给保存按钮绑定事件

    吧用户预定记录的数据发送到后台

    发送ajax请求


function initSaveEvent() {         $("#save").click(function () {             $.ajax({                 url:"/recording/",                 type:"post",                 data:{                        data:JSON.stringify(POST_DATA),  //要发送的用户传过来的时间                        date:CHOISE_DATE,  //发送的日期时间                        csrfmiddlewaretoken:'{{ csrf_token }}'                     },                  success:function (data) {                     console.log(data);                     if (data.status){                         initRecoringInfo(CHOISE_DATE)                     }                     else {                         alert(data.msg)                     }                 }             })         })     }


  用户选择的日期date,怎么拿呢?在来一个全局变量

  默认是CHOISE_DATE = new Date().Format("yyyy-MM-dd")

  change 的时候会修改

    function change(){

        CHOISE_DATE = new Date().Format("yyyy-MM-dd")

        initserverecoing(CHOISE_DATE)

    }

    8、csrf验证的三种方式:

      1、带着数据发过去

      2、从cookie中拿到,带着请求头发给后台

      3、在发数据的时候{{ csrf_token }} #不推荐

========================数据发送到后台以后======================

发过来的日期和当前的日期还是进行一个比较,

然后在后端处理数据,,该保存的保存,该删除的删除(删除的时候用Q查询,外面是或关系,里面是or关系)

然后数据如果成功之后,再去发送ajax请求,调用函数

三、涉及到的相关知识点:

1、用户登录

用户登录成功之后吧用户id和用户名设置在session或者cookie中

注意:设置cookie的时候要设置成签名的cookie,也就是加密的cookie


obj = redirect("/index/")    obj.set_cookie("id",user.id)  #明文的cookie    obj.set_signed_cookie("id",user.id,salt="aaaa") #密文的cookie return obj



2、一周没免登录:也就是设置cookie和session的过期时间(默认是两周)


主动设置超时时间:request.session.set_expiry(60 * 60 * 24 * 30)



3、判断用户是否已经登录,有两种方式:

方式一:装饰器(就有几个函数的时候用装饰器)

方式二:中间件(大型项目的时候用中间件)

4、写功能的时候获取并显示数据

- 要么在用模板渲染

- 要么返回页面,ajax获取数据

5、前端发送数据

- Form表单提交

- Ajax提交
