表结构设计
from django.db import models
# Create your models here.
from django.db import models
from django.contrib.auth.models import AbstractUser
class UserInfo(AbstractUser):
tel=models.CharField(max_length=32)
class Room(models.Model):
"""
会议室表
"""
caption = models.CharField(max_length=32)
num = models.IntegerField()
def __str__(self):
return self.caption
class Book(models.Model):
"""
会议室预定信息
"""
user = models.ForeignKey('UserInfo')
room = models.ForeignKey('Room')
date = models.DateField()
time_choices = (
(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'),
)
time_id = models.IntegerField(choices=time_choices)
class Meta:
unique_together = (
('room','date','time_id'),
)
def __str__(self):
return str(self.user)+"预定了"+str(self.room)
共三张表，用户表，会议室房间表和会议室预定情况表
URL设计
from django.conf.urls import url
from django.contrib import admin
from app01 import views
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^index/', views.index),
url(r'^login/', views.login),
url(r'^book/', views.book),
]
index页面用来显示所以会议室的预定情况，login用来登录，book用来处理用户发送的数据和逻辑
index视图
def index(request):
current_date = datetime.datetime.now().date()
book_date = request.GET.get("book_date", current_date.strftime("%Y-%m-%d"))
book_date = datetime.datetime.strptime(book_date, "%Y-%m-%d")
time_choices = Book.time_choices
room_list = Room.objects.all()
book_list = Book.objects.filter(date=book_date)
html = ""
for room in room_list:
s = '<tr><td>{0}({1})</td>'.format(room.caption, room.num)
for item in time_choices:
flag = False
for book in book_list:
if book.room.caption == room.caption and book.time_id == item[0]:
flag = True
break
if flag:
if request.user.pk != book.user.pk:
s += '<td class="active_other item" room_id="{0}" time_id="{1}">{2}</td>'.format(room.pk, item[0],
book.user.username)
else:
s += '<td class="active item" room_id="{0}" time_id="{1}">{2}</td>'.format(room.pk, item[0],
book.user.username)
else:
s += '<td class="item" room_id="{0}" time_id="{1}"></td>'.format(room.pk, item[0])
s += "</tr>"
html += s
return render(request, 'index.html', locals())
首先我们要从访问的url中取出用户访问的日期，如果没有则默认为当天的日期，然后要取到所有的会议室信息和日期对应的会议室预定情况，如果将这些信息直接传到前端，渲染时由于一些逻辑无法使用，会造成一定的困难，所以我们直接在后端进行逻辑判断，将要渲染的标签内容生成字符串，然后再床给前端

添加和删除JS效果以及ajax发送数据

点击某一个房间的时间段时我们应该让他变颜色，并且我们需要利用一种数据格式来存放我们要添加的内容，最后利用ajax直接发送到后端
