Question

Have AttributeError 'QueryDict' object has no attribute 'first_name' Get examples from here. I'm don't understand what is the problem
models.py
class Employee(models.Model):
first_name = models.CharField(max_length=30)
second_name = models.CharField(max_length=30)
patronymic = models.CharField(max_length=30)
birth_date = models.DateField()
views.py
def edit_employee_action(request, employee_id):
if request.method == "POST":
form = AddEmployeeForm(request.POST)
if form.is_valid():
edited = Employee.objects.filter(pk=employee_id)
edited.update(
first_name = request.POST.first_name,
second_name = request.POST.second_name,
patronymic = request.POST.patronymic,
birth_date = request.POST.birth_date
)
else:
form = AddEmployeeForm()
form = AddEmployeeForm()
return render(
request,
'edit_employee.html',
context={'form': form}
)
The parameter employee_id is correct (debugged).

Answer 1

you need to get the value from request.POST like this:
request.POST['first_name']
(this approach will raise KeyError if first_name is not available in request.POST)
or
request.POST.get('first_name')

Answer 2

You are using incorrectly the request.POST. It is actually a `dictionary. Try the following.
def edit_employee_action(request, employee_id):
if request.method == "POST":
form = AddEmployeeForm(request.POST)
if form.is_valid():
edited = Employee.objects.filter(pk=employee_id)
edited.update(
first_name = request.POST.get('first_name'),
second_name = request.POST.get('second_name'),
patronymic = request.POST.get('patronymic'),
birth_date = request.POST.get('birth_date')
)
else:
form = AddEmployeeForm()
form = AddEmployeeForm()
return render(
request,
'edit_employee.html',
context={'form': form}
)
This way even if the key does not exist you'll get a None value instead of an exception. Also be sure that the key values are the same in your template.
