### 基于 Python 的医院挂号系统代码示例 #### 功能概述 该系统实现了基本的医院挂号功能，包括患者信息录入、预约科室选择以及医生排班查看等功能。通过 Django 框架构建 Web 应用程序，并利用 Vue.js 进行前端页面渲染[^1]。 #### 数据库模型定义 首先，在 `models.py` 文件中定义数据库表结构： ```python from django.db import models class Patient(models.Model): name = models.CharField(max_length=50, verbose_name='姓名') gender = models.CharField(max_length=10, choices=(('male', '男'), ('female', '女')), default='male', verbose_name='性别') age = models.IntegerField(verbose_name='年龄') class Meta: db_table = 'patient' verbose_name_plural = '患者' class Department(models.Model): dept_name = models.CharField(max_length=50, unique=True, verbose_name='科室名称') class Meta: db_table = 'department' verbose_name_plural = '科室' class Doctor(models.Model): doc_name = models.CharField(max_length=50, verbose_name='医生姓名') department = models.ForeignKey(Department, on_delete=models.CASCADE) class Meta: db_table = 'doctor' verbose_name_plural = '医生' class Appointment(models.Model): patient = models.ForeignKey(Patient, on_delete=models.CASCADE) doctor = models.ForeignKey(Doctor, on_delete=models.CASCADE) appointment_date = models.DateTimeField(auto_now_add=False, verbose_name='预约时间') class Meta: db_table = 'appointment' verbose_name_plural = '预约记录' ``` #### 视图逻辑处理 接着编写视图函数来处理用户的请求并返回响应数据给前端展示： ```python from django.shortcuts import render, redirect from .forms import PatientForm, AppointmentForm from .models import * def index(request): departments = Department.objects.all() context = {'departments': departments} return render(request,'index.html',context=context) def make_appointment(request,id=None): if request.method == "POST": form = AppointmentForm(data=request.POST) if form.is_valid(): obj=form.save(commit=False) obj.patient_id=id obj.save() return redirect('/') else: form = AppointmentForm(initial={'patient':id}) patients = Patient.objects.filter(id=id).first() doctors = Doctor.objects.select_related().all() context={ 'form':form, 'patients':patients, 'doctors':doctors } return render(request,"make_appointmet.html",context=context) def add_patient(request): if request.method=="POST": form=PatientForm(data=request.POST) if form.is_valid(): form.save() return redirect('/add-patient/') else: form=PatientForm() context={"form":form} return render(request,'add_patient.html',context=context) ``` 上述代码片段展示了如何创建一个简单的基于Django框架的Web应用程序用于实现医院挂号系统的部分核心业务流程。 #### 表单设计 为了方便用户提交信息，还需要准备对应的HTML模板文件和表单类来进行交互操作。这里省略具体细节，主要关注后端逻辑实现。 ---
