我应该如何保存到数据库？

Question

我在 Django 中创建了一个客户模型，但无法将数据保存到数据库表中，当我单击注册按钮时，它只会将我重定向回主页。 我在客户模型和注册功能下方附上了。 ...请帮我解决问题。 客户.py

from django.db import models

class Customer(models.Model):
    first_name= models.CharField(max_length=50)
    last_name= models.CharField(max_length=50)
    phone=models.CharField(max_length=15)
    email=models.EmailField()
    password=models.CharField(max_length=500)

    def register(self):
        self.save()

views.py

def signup(request):
    if request.method == 'GET':
        return render(request, 'signup.html')
    else:
        postData=request.POST
        first_name=postData.get('firstname')
        last_name=postData.get('lastname')
        phone=postData.get('phone')
        email=postData.get('email')
        password=postData.get('password')
        print(first_name,last_name,phone,email,password)
        customer=Customer(first_name=first_name,last_name=last_name,phone=phone,email=email,password=password)
        customer.register()
        return HttpResponse("Signup success")
