发布会签到系统_系统开发_数据库表设计

本项目做的是一个基于django的发布会签到系统，本文进一步实现了数据表设计。关于数据表设计的详细思路及相关知识点将以思维导图模式放在本文。实现代码将放在文末。

数据表设计：
1.通过模型（models.py）完成表的创建
2.进行数据迁移（migrate）
3.通过后台或shell命令操作表的数据
4.由于django自带的SQLite3数据库不适用于大型项目，所以配置MySQL

【models.py】

from django.db import models


class Event(models.Model):   # 发布会表
    name = models.CharField(max_length=100)   # 发布会标题
    limit = models.IntegerField()  # 参加人数
    status = models.BooleanField()  # 状态
    address = models.CharField(max_length=200)    # 地址
    start_time = models.DateTimeField('events time')   # 发布会时间
    create_time = models.DateTimeField(auto_now=True)  # 创建时间（自动获取当前时间）

    def __str__(self):
        return self.name


class Guest(models.Model):  # 嘉宾表
    event = models.ForeignKey(Event)      # 关联发布会id
    realname = models.CharField(max_length=64)  # 姓名
    phone = models.CharField(max_length=16)   # 手机号
    email = models.EmailField()  # 邮箱
    sign = models.BooleanField()  # 签到状态
    create_time = models.DateTimeField(auto_now=True)  # 创建时间（自动获取当前时间）

    class Meta:
        unique_together = ('event', 'phone')

    def __str__(self):
        return self.realname

【admin.py】

from django.contrib import admin
from sign.models import Event, Guest


# Register your models here.
class EventAdmin(admin.ModelAdmin):
    list_display = ['id', 'name', 'status', 'address', 'start_time']
    search_fields = ['name']   # 搜索栏
    list_filter = ['status']    # 过滤栏


class GuestAdmin(admin.ModelAdmin):
    list_display = ['realname', 'phone', 'email', 'sign', 'create_time', 'event']
    search_fields = ['realname', 'phone']   # 搜索栏
    list_filter = ['sign']           # 过滤栏


admin.site.register(Event, EventAdmin)
admin.site.register(Guest, GuestAdmin)
