This is my model.
class Project(models.Model):
id = models.AutoField(primary_key=True)
user = models.ForeignKey(CustomUser, on_delete=models.PROTECT, editable=False)
name = models.CharField(max_length=20)
total = models.DecimalField(max_digits=7, decimal_places=2, default=0)
created = models.DateTimeField(auto_now_add=True)
updated = models.DateTimeField(auto_now=True)
comission_owed = models.DecimalField(max_digits=7, editable=False, decimal_places=2, default=0)
comission_paid = models.DecimalField(max_digits=7, editable=False, decimal_places=2, default=0)
def __str__(self):
return self.name
And this is my model form:
class ProjectForm(ModelForm):
required_css_class = 'required'
class Meta:
model = Project
fields = '__all__'
def __init__(self, *args, **kwargs):
self.user = kwargs.pop('user')
super().__init__(*args, **kwargs)
self.fields['user'].initial = self.user
and then here's my view:
def add_project(request):
submitted = False
if request.method == "POST":
form = ProjectForm(data=request.POST, user=request.user)
if form.is_valid():
form.save()
return HttpResponseRedirect('/add_project/?submitted=True')
else:
form = ProjectForm()
if 'submitted' in request.GET:
submitted = True
return render(request,
'add_project.html',
{'form': form, 'submitted': submitted}
)
I am trying to get the "user" filled by getting the logged in user but when loading the url "add_project/" where the form should load and let me submit I get an error that traces back to
KeyError at /add_project/

You are getting this error because you are not passing the user object to your ProjectForm in the else block.
def add_project(request):
submitted = False
if request.method == "POST":
...
else:
# Here, you should pass the user object too
form = ProjectForm(user=request.user)
...
def add_project(request):
submitted = False
if request.method == "POST":
project = ProjectForm.save(commit=False)
project.user = request.user
else:
.....
you can try this to get the user, and save in projectv.user

You aren't passing the required session argument in this line:
view=ViewCount(blogview=blog, ip_address=ip, session=request.session.session_key)
Since the user isn't logged in, the value is Null.
Allow the value to be Null:
`session=models.CharField(max_length=50, null = True)`
Or generate a session for an anonymous user.
I have a function in my Post model, a get_absolute_url which is a reverse for 'post-detail', it has kwargs for primary key , how do i add another for slug; which is in my Profile model.

Your get_absolute_url in Post doesn't have slug in kwargs or I'm missing something? 'slug': self.user_name.profile.slug

Since you have override the __init__(...) method, Django expects the arguments in the different order.
So change
form = ImamForm(request.POST, instance=masjid)
to
form = ImamForm(masjid,request.POST)
I input qualified content to form but was checked as invalid by form.is_valid,
Here is my views:

return redirect(f"/article/detail/{ pk }")
def post(self, request, pk):
self.article = Article.objects.get(id=pk)
form = CommentForm(request.POST)
print(request.POST) # test input
if form.is_valid():
print("form is valid.") #assert valid
comment = form.save(commit=False)
print(f"Comment: {form.cleaned_data}")
comment.owner = request.user
comment.article = self.article
comment.status = 0
comment.save()
return redirect(f"/article/detail/{ pk }")
else:
print("form is invalid.") #assert invalid
comments = (Comment.objects
.filter(article=self.article, status=0)

context = {'article': self.article,

"form": form}
return render(request, self.template_name, context)
The Comment model data`:

How to solve such a problem?
I'm trying to do a form so a user can upload a video, the problem is i can't get current user or it's id as a foreign key on my video model
Error: IntegrityError
Exception Value: (1048, "Column 'owner_id' cannot be null")
How can i solve the problem please, i looked at django documentation but doesn't find answer.
My models.py:
class Videowtm(models.Model):
name = models.CharField(max_length=50, blank=True)
description = models.CharField(max_length=255, blank=True)
uploaded_at = models.DateTimeField(auto_now_add=True)
owner = models.ForeignKey(User)
video = models.FileField(upload_to='videos/')
My forms.py:
class VideowtmForm(forms.ModelForm):
class Meta:
model = Videowtm
fields = ('name', 'description', 'video', )
My views:
#login_required
def model_form_upload(request):
if request.method == 'POST':
form = VideowtmForm(request.POST, request.FILES)
form.owner = request.user
if form.is_valid():
form.save()
return redirect('home')
else:
form = VideowtmForm()
return render(request, 'model_form_upload.html', {
'form': form
})
Try this one:
first add blank=True to the owner in your model:
###No need for this if you don't include it in your form fields###
class Videowtm(models.Model):
name = models.CharField(max_length=50, blank=True)
description = models.CharField(max_length=255, blank=True)
uploaded_at = models.DateTimeField(auto_now_add=True)
owner = models.ForeignKey(User, blank=True)
video = models.FileField(upload_to='videos/')
and then:
views.py:
#login_required
def model_form_upload(request):
if request.method == 'POST':
form = VideowtmForm(request.POST, request.FILES)
if form.is_valid():
video = form.save(commit=False)
video.owner = request.user
video.save()
return redirect('home')
else:
form = VideowtmForm()
return render(request, 'model_form_upload.html', {
'form': form
})
