how can users upload file into Django model? - django

Question

With these codes, I want each user to be able to upload their own file in their own model
forms.py:
class sp_UserNewOrderForm(forms.Form):
file= forms.FileField()
models.py:
class sp_Order(models.Model):
owner = models.ForeignKey(User, on_delete=models.CASCADE)
def __str__(self):
return self.owner.username
class sp_OrderDetail(models.Model):
order = models.ForeignKey(sp_Order, on_delete=models.CASCADE)
file= models.FileField()
def __str__(self):
return self.order.owner.username
views.py:
#login_required
def add_user_order(request):
new_order_form = sp_UserNewOrderForm(request.POST or None)
if new_order_form.is_valid():
order = sp_Order.objects.filter(owner_id=request.user.id).first()
if order is None:
order = sp_Order.objects.create(owner_id=request.user.id)
file= new_order_form.cleaned_data.get('file')
order.sp_orderdetail_set.create(file=file)
# todo: redirect user to user panel
# return redirect('/user/orders')
return redirect('/')
return redirect('/')
HTML:
<form method="post" action="/add_sp">
{% csrf_token %}
{{ form.count }}
<button type="submit" class="btn btn-primary container">
upload
</button>
</form>
But these codes do not create the model. what is the problem?

Answer 1

The problem appears to be in this line:
order = sp_Order.objects.filter(owner_id=request.user.id).first()
I think you should replace owner_id = request.user.id with owner = request.user
owner_id is not an attribute of the model you're trying to filter or create

Answer 2

You need to include request.FILES when instantiating the form for the POST request.
def add_user_order(request):
if request.method == 'POST':
new_order_form = sp_UserNewOrderForm(request.POST, request.FILES)
if new_order_form.is_valid():
order = sp_Order.objects.filter(owner_id=request.user.id).first()
if order is None:
order = sp_Order.objects.create(owner_id=request.user.id)
file= new_order_form.cleaned_data.get('file')
order.sp_orderdetail_set.create(file=file)
# todo: redirect user to user panel
# return redirect('/user/orders')
return redirect('/')
