I am using django 2.2. My models are
class Group(models.Model):
group_name = models.CharField(max_length=100)
def __str__(self):
return self.group_nameclass Category(models.Model):
category_name = models.CharField(max_length=50)
def __str__(self):
return self.category_nameclass Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
board = models.CharField(choices=board_options,max_length=1,null=True)
group = models.ForeignKey(Group,on_delete=models.CASCADE,null=True)
class Subject(models.Model):
subject_name = models.CharField(max_length=50)
subject_category = models.ForeignKey(Category, on_delete=models.CASCADE)
subject_photo = models.ImageField(null=True,blank=True)
def __str__(self):
return self.subject_name
class Subject_Assignment(models.Model):
board = models.CharField(choices=board_options,max_length=1,null=True)
group = models.ForeignKey(Group,on_delete=models.CASCADE,null=True)
Subject = models.ForeignKey(Subject, on_delete=models.CASCADE)
class Mark_Survey(models.Model):
survey_name = models.CharField(max_length=50)
opens_at = models.DateField()
ends_at = models.DateField()
class Survey_Mark(models.Model):
mark_survey = models.ForeignKey(Mark_Survey,on_delete=models.CASCADE)
user = models.ForeignKey(User, on_delete=models.CASCADE)
Subject = models.ForeignKey(Subject, on_delete=models.CASCADE)
marks = models.IntegerField()
Here am creating a formset for Survey_Mark and my form should get marks of
all Subject. By using Subject_Assignment i can get all the subjects of the
particular user.The following view works for the get method but throws
error in post method.
def postsurvey(request,pk):
#post = get_object_or_404(Mark_Survey, pk=pk)
SurveyFormSet = modelformset_factory(Survey_Mark,
fields=('marks','Subject'),extra=0)
if request.method == "POST":
formset = SurveyFormSet(request.POST,request.FILES)
print(formset.data)
print(formset.errors)
if formset.is_valid():
post = formset.save(commit=False)
post.mark_survey=pk
post.user=request.user
post.save()
html = "<html><body>Success</body></html>" % now
return HttpResponse(html)
else:
print("failure")
html = "<html><body>failure </body></html>"
return HttpResponse(html)
else:
user=request.user
profile = get_object_or_404(Profile,user_id=user.id)
formset =
SurveyFormSet(queryset=Subject_Assignment.objects.filter(Q(board=profile.board)
& Q(group=profile.group)))
return render(request, 'subject_assignment_detail.html',
{'formset': formset})
Am getting id the field is required error. if i used {{ hidden }} in
template then am getting *Select a valid choice. That choice is not one of
the available choices* error in post method.I want to get marks of all the
subject in single form and save it in the corresponding table
