在没有Form的情况下更新django中的数据

Question

我正在做没有表单的CRUD操作。我想通过id更新数据。我的数据正在更新，但在额外的后台获取数据，像这样

反应:{"customer_id":2,"customer_name":"("什维塔")","销":"("400456")","城市":"("DSAA")","状态":"("马哈拉施特拉邦")","国家":"("印度",)","customer_address":"("印度",)","contact_person_name":"(‘8097998823’)","电话":"("7418529634")","电子邮件":"("[e-mail]")","消费税":"("741852")","bill_to":"("领主")","ship_to":"("领主")","备注":"("NA")"}

views.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})

如何使我的数据像没有桶一样干净?

Answer 1

不经过验证的更新是错误的。

但是你可以这样做:

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
