ModelChoiceField - get request.user.username-CodePudding

I need to choose User to form by the request.user.username and save into the database. Here I have a code of forms.py

class Send(forms.ModelForm):
  sender = forms.ModelChoiceField(queryset=User.objects.order_by('username')

Here is the models.py, where I am going to save the data about the user:

class SendM(models.Model):
 sender = models.ForeignKey(User, null=True, blank=False, on_delete=models.CASCADE)

And here is views.py, where I get the data

def form_create(request):
   if not request.user.is_anonymous:
        form = Send(request.POST or None, initial={'sender': request.user.username})

   if request.method == "POST":
      if form.is_valid():
         send = SendM(sender=User.objects.get(username=form.cleaned_data['sender']))
      send.save()
      return redirect("/")

To understand I want to pre-filled the array with the user found in database.

Thank you very much!!

CodePudding user response：

The initial value in the form is the user reference, not the username, because you're using a ModelChoiceField. I don't really remember now if it's the model instance (initial={'sender': request.user}) or the model primary key (initial={'sender': request.user.pk}) .

Then after form.is_valid(), there is no need to get the user from the database again. You just need to call the save method on the form. Django does the rest.


if form.is_valid():
    send = form.save()
