python-3.x - 通过表单提交数据但未存储在数据库中

问题描述

我已经创建了models.py和views.py，想通过首页提交数据，那些需要存储在数据库中但未能发送数据的人。当我在填写表单后单击提交时，它会转到 views.py 中提到的 else 块，但不检查 if 语句。帮助申请。

模型.py

from django.db import models

# Create your models here.

# creating modeles here and storing in database acts as mysql

class Contact(models.Model):
    usn = models.CharField(max_length=50, primary_key=True)
    name = models.CharField(max_length=50, default="")
    sem = models.CharField(max_length=50, default="")
    phone = models.CharField(max_length=50, default="")
    email = models.CharField(max_length=50, default="")

    def __str__(self):
        return self.name

视图.py

from django.shortcuts import render, redirect, HttpResponse
from django.conf import settings
from .models import Contact


# Create your views here.
def index(request):
    if request.method=="POST":
        usn = request.POST.get('usn','')
        name = request.POST.get('name','')
        sem = request.POST.get('sem','')
        phone = request.POST.get('phone','')
        email = request.POST.get('email', '')

        if usn and name and sem and phone and email:
            contact = Contact(usn = usn, name = name, sem = sem, phone = phone, email = email)
            contact.save()
        else:
            return HttpResponse("Enter all details")
    return render (request, 'index.html')
