之前发布的文章实现一个简单的停车场管理系统，有很多同学私信了多修改项。

【Python+Django】一个简单Web停车场管理系统的快速实现（极简版）文章浏览阅读688次，点赞4次，收藏13次。本文利用Python的Django框架从0开始最终实现一个简单的Web 停车场管理系统。目前一个典型的停车场管理包含如下几个功能：1、扫描车牌识别自动出入场2、会员管理（充值，提醒充值。。等）3、收费（如果是有效期内的会员就免费）为了实现上面几个功能，我们先简单的做下数据库和页面的设计。● 停车场管理系统 ○ 会员管理 ■ 会员充值 ■ 会员查看 ○ 车辆入场管理 ■ 车牌识别 ■ 入场记录 ○ 车辆出场管理 ■ 车牌识别 ■ 出场记_parkmanage 数据库iphttps://blog.csdn.net/agelee/article/details/130229606

花了一些时间在原来的基础上做了些升级改造，完善了注册登录及页面的样式的优化。

软件及版本

开发相关的技术和软件版本如下：

服务端：Python 3.9

Web框架：Django 4.10

数据库：MySQL mysql-8.0.13-winx64

开发工具IDE：Pycharm

大家参考学习的时候最好使用相同的版本。

停车场管理系统的功能模块设计

一个典型的停车场管理系统，主要包含如下几个功能模块：

1、会员管理：会员注册，会员充值，会员查看和修改。

2、车辆入场管理：车牌扫描，入场记录

3、车辆出场管理：车牌扫描，出场记录，收费管理

4、报表数据管理：dashboard，出入场记录

5、用户管理：用户注册及登录

数据库设计

按照前面的功能模块，我们需要自定义数据表如下：

会员表：vip_user

车辆记录表：car_record

后续为了实现车牌扫描功能，我们还需要增加扫描结果记录表：license_plate

另外我们为了快速实现系统，用户管理功能实现我们直接基于Django自带的用户及认证模块。

以下是各表结构

vip_user 表:

car_record 表:

License_plate 表:

Charge_type 表:

页面及功能设计

为了实现我们前面的功能模块我们设计如下几个功能页面：

1、登录页面：

其中需要登录，校验，登录后同时需要存储用户信息在Session中，以备登录后的页面使用。

2、注册页面：

提供注册信息表单，提交注册通过后，系统生成一个新的用户。

3、首页（Dashboard）：

通过卡片和图表的形式展示停车场的关键信息

4、车辆入场管理：

车牌扫描，入场记录

5、车辆出场管理：

车牌扫描，出场记录，收费管理

6、报表数据管理：

dashboard，出入场记录

7、用户管理：

完整文件结构目录

系统实现代码

代码较多，以下为一些关键代码

定义注册登录的Form

app01/forms.py

# 引入表单类from django import forms# 引入 User 模型from django.contrib.auth.models import User# 登录表单，继承了 forms.Form 类class UserLoginForm(forms.Form):username = forms.CharField()password = forms.CharField()# 注册用户表单class UserRegisterForm(forms.ModelForm):# 复写 User 的密码password = forms.CharField()password2 = forms.CharField()class Meta:model = Userfields = ('username', 'email')# 对两次输入的密码是否一致进行检查def clean_password2(self):data = self.cleaned_dataif data.get('password') == data.get('password2'):return data.get('password')else:raise forms.ValidationError("密码输入不一致,请重试。")

定义模型

app01/models.py

from django.db import modelsfrom django.contrib.auth.models import User# Create your models here.class vip_uer(models.Model):name = models.CharField(max_length=32, verbose_name='姓名')carnum = models.CharField(max_length=32, unique=True, verbose_name='车牌号')phone = models.CharField(max_length=32, verbose_name='手机号')begintime = models.DateTimeField(auto_now=False, auto_now_add=False)endtime = models.DateTimeField(auto_now=False, auto_now_add=False)user = models.OneToOneField(User, on_delete=models.CASCADE)class car_record(models.Model):carnum = models.CharField(max_length=32, verbose_name='车牌号')intime = models.DateTimeField(auto_now=False, auto_now_add=False, verbose_name='入场时间')outtime = models.DateTimeField(auto_now=False, auto_now_add=False, verbose_name='出场时间', null=True, blank=True)paytime = models.DateTimeField(auto_now=False, auto_now_add=False ,verbose_name='收费时间', null=True, blank=True)amount = models.IntegerField(verbose_name='收费金额', null=True, blank=True)class License_plate(models.Model):car_img = models.ImageField(upload_to='car_imgs',unique=True, blank=True, null=True)car_num = models.CharField(max_length=32, unique=True, verbose_name='车牌号', null=True)color = models.CharField(max_length=32, verbose_name='车牌颜色')class Charge_type(models.Model):type = models.CharField(max_length=32, verbose_name='套餐')amount = models.IntegerField(verbose_name='费用（元）', null=True, blank=True)remark = models.CharField(max_length=50, verbose_name='备注')

视图实现

调用百度云图像识别视图
