Adding a comment section form to my Django app - django

Question

I get 2 different errors the first one is
Django Model IntegrityError: NOT NULL constraint failed:
I checked the solution for this, people said I've to make my FK attributes null = true and blank = true
so this solved that.
The second error I got after that was in my views.py
'CommentForm' object has no attribute 'cleaned_data'
My Views.py file:
def project(request, pk):
form = CommentForm()
project = ProjectModel.objects.get(id=pk)
contextt ={
"project": project,
"form":form,
}
if request.method == "POST":
form.save()
return redirect(request, "/dashboard")
else:
return render(request, "projects.html", contextt)
and my Models.py:
class ProjectModel(models.Model):
caption = models.CharField(max_length=100)
video = models.FileField(upload_to="video/%y", validators=[file_size])
ProjectName = models.CharField(max_length=50, )
ProjectDescription = models.TextField(max_length=1000,)
Project_Background_picture = models.ImageField(
upload_to=settings.MEDIA_ROOT, default='/static/img/default.png')
Approved = models.BooleanField(default=False)
Finished = models.BooleanField(default=False)
Goal = models.DecimalField(
decimal_places=3, max_digits=6, blank=True, null=True)
Pledges = models.DecimalField(
decimal_places=3, max_digits=6, blank=True, null=True)
Number_of_investors = models.IntegerField(blank=True, null=True)
FirstReward = models.TextField(max_length=1000, default=' 10$ ')
SecondReward = models.TextField(max_length=1000, default=' 25$')
ThirdReward = models.TextField(max_length=1000, default='50$')
FourthReward = models.TextField(max_length=1000, default='100$ +s')
def __str__(self):
return self.caption
class comment(models.Model):
ProjectModel = models.ForeignKey(
ProjectModel, related_name='comments', on_delete=models.CASCADE, null=True, blank=True)
name = models.CharField(max_length=255)
CommentBody = models.TextField(default='comment here!', max_length=1000 )
date_added = models.DateTimeField(auto_now_add=True)
def _str_(self):
return '%s - %s' % (self.ProjectModel.caption, self.name)

try this:
def project(request, pk):
form = CommentForm()
project = ProjectModel.objects.get(id=pk)
contextt ={
"project": project,
"form ":form ,
}
if request.method == 'POST' :
form = CommentForm(data=request.POST)
if form.is_valid():
form= form.save(commit=False) #new line
form.ProjectModel = project #new line
form.save()
return redirect("/dashboard")
else:
return render(request, "projects.html", contextt)
