class Member(models.Model):# member db table
    userID      = models.CharField(max_length=80,primary_key=True) #user id 
    password    = models.CharField(max_length=32)# password
    nickname    = models.CharField(max_length=100)# user nickname
    penalty     = models.PositiveSmallIntegerField(max_length=10,default=0,null=True)
    participation=models.ForeignKey('Room',default=None,blank=True,null=True)

def __unicode__(self):
        return self.userID

def doJoin(request):
    if request.is_ajax() and request.method == 'POST':
        # check validation
        userID = request.POST['userID']
        userNickname = request.POST['nickname']
        if (checkID(userID) == False) and (checkNickname(userNickname) == False) :
            #save to the database
            newUser = Member()
            newUser.userID = userID
            newUser.nickname = userNickname
            newUser.password = request.POST['password']
            print newUser.userID , newUser.nickname , newUser.password , newUser.penalty , newUser.participation
            newUser.save() #<------------error line!!!!

            return HttpResponse('true')
        else:
            return HttpResponse('false')
    else:
        HttpResponse('false')

line about 8

In function doJoin:

newUser.save() # <--- error... so sad...

What should I do? Help me please.

What’s wrong in this source?

Answer 1

Do you have debugging turned off? If you’re getting a 500 and you have debugging turned on, you’ll get a stack trace with the exception.

What are checkID() and checkNickname() doing? If those are performing some sort of validation, you really should be doing that in a form class instead of in the view. I also wouldn’t be pulling values directly out of the request.POST to populate your model. I would highly recommend retrieving those values from a form’s cleaned_data dictionary.
