在没有形式的情况下以Django更新数据

Question

我在没有形式的情况下进行CRUD操作。我想通过其ID更新数据。我的数据正在更新，但在诸如此响应之类的额外替补中获取数据

：{'customer_id'：2，'customer_name'：“（'shweta'，），'pin'：“（'400456'，），”，“，”，“） 'city'：“（'dsaa'，）”，'state'：“（'Maharashtra'，），'country'：“（'印度'，），”，“）， 'customer_address'：“（'印度'，）”，'Contact_person_name'：“（'80979998823'，）“），'Phone'：“（'7418529634'，），'，'电子邮件，'电子邮件'： “/cdn-cgi/l/电子邮件保护” class =“ __ cf_email__” data-cfemail =“ e0898e868fce94858388E8989839281869493A0878D81898CCE838F8D”> [email＆nbsp; nbsp; procected] 'ship_to'：“（'thane'，）”，'备注'：“（'na'，）”}

views.pys.py

def updateCustomer(request,id):
customer=Customer.objects.get(pk=id)
response = model_to_dict(customer)
print ("response:" , response)
if request.method == "POST":
    # customer_id= request.POST['customer_id'],
    customer_name= request.POST['customer_name'],
    pin= request.POST['pin'],
    city= request.POST['city'],
    state= request.POST['state'],
    country= request.POST['country'],
    customer_address= request.POST['customer_address'],
    contact_person_name= request.POST['contact_person_name'],
    phone= request.POST['phone'],
    email= request.POST['email'],
    gst= request.POST['GST'],
    bill_to= request.POST['bill_to'],
    ship_to= request.POST['ship_to'],
    remarks= request.POST['remarks'],
    
    update_customer=Customer.objects.filter(customer_id=id).update(customer_name=customer_name,pin=pin,city=city,state=state,country=country,customer_address=customer_address,contact_person_name=contact_person_name,phone=phone,email=email,GST=gst,bill_to=bill_to,ship_to=ship_to,remarks=remarks)
    print("update query set: ",update_customer)
    
return render(request,"customers/update-customer.html",{"customer":response})

我如何获取我的数据像没有酒吧一样干净吗？

Answer 1

未经验证的更新是错误的方式。

但是你可以做到：

def updateCustomer(request,id):
    ... # something, what you want
    data = request.POST
    customer=Customer.objects.get(pk=id)
    [setattr(customer, field.name, data.get(field.name)) for field in customer._meta.fiellds if field.name in data]
    customer.save()
    ... # something, what you want
