Django数据库无法存储数据，实例化appointment模型时报TypeError

问题代码与报错 #

views.py 相关代码 #

def thanks(request):
    if request.method == 'POST':
        name = request.POST['name']
        email = request.POST['email']
        phone= request.POST['phone']
        doctor = request.POST['doctor']
        msg = request.POST['reason']
        print(name, email, phone, msg)
        appointment_db = appointment(name=name, email=email, phone=phone, doctor=doctor, message=msg)
        appointment_db.save()
    return render(request, "thanks.html", {"name": name})

models.py 模型代码 #

from django.db import models

# Create your models here.
class appointment(models.Model):
    count=models.AutoField(primary_key=True)
    name= models.CharField(max_length=100)
    email= models.EmailField(max_length=1000)
    phone = models.IntegerField()
    message =models.TextField(max_length=5000)
    doctor = models.CharField(max_length=100)

    def __str__(self):
        return self.name + " | "+ "Doctor : "+ self.doctor

报错信息 #

TypeError: appointment() got an unexpected keyword argument 'name'

错误原因 #

虽然模型代码里明确定义了name字段，但报错提示该参数不被识别，最常见的原因是模型修改后未执行数据库迁移操作，导致数据库中的appointment表实际没有name字段，和代码中的模型类结构不匹配。此外也需要确认views.py中导入的appointment是否是你自己定义的模型，而非其他同名类。

解决方案 #

1. 生成迁移文件：在项目根目录下执行命令

python manage.py makemigrations

2. 应用迁移到数据库：接着执行

python manage.py migrate

3. 验证迁移结果：可以通过Django后台管理查看appointment数据是否能正常添加name字段，或者直接查看数据库表结构确认name字段存在。
4. 检查模型导入：确保views.py顶部的导入语句正确，比如：

from .models import appointment

避免导入了其他模块的同名appointment类。
