Question

I have a django app with several form that I am trying to migrate to ajax. I am doing this because I want to update my data without refreshing my screen. I used the dajax library and started moving some of my views.py code into ajax.py.

I am getting a “ValueError: too many values to unpack ” in code that worked fine in views.py. I’m not sure why this is happening or how to fix it. Advice?

ajax.py

def send_student_form(request, form):
  dajax = Dajax()
  #error is here
  student = Student.objects.get( form.get('student_id'))
  #student = Student()  # no ValueError, but it doesn't find my student.
  if student:
    print "Student Found!"
    sForm = StudentProfileForm(request.POST, instance=student) 
    print student
  else:
    print "Student Not Found"
    sForm = StudentProfileForm(request.POST)
    #TODO: new Student

Answer 1

You need to define which field you are querying, for example:

# Query by primary key
student = Student.objects.get(pk = form.get('student_id'))

Using non-keyword syntax is also allowed, but ugly. Non-keywords arguments are a special case in Django’s query building process, see constructor of the Q class if you want to know more.

student = Student.objects.get(("pk", form.get('student_id')))
