Problem with migrating my Database using Django
I currently have a database using Heroku and want to migrate it to AWS, where both use PostgresSQL. So, after some digging on how to get it done I followed the steps as on this youtube video. I initially ran python manage.py dumpdata > dumpdata.json with my Heroku database credentials in Django.

The idea is a user will create a post on this page and fill out the title and content. Once they submit this form, a Post instance will be created with the inputs of the user for title and content. This instance will also have the id of the user associated to it. I've done a print test which yields the outputs I'm looking for but it appears that the form is not valid. Any thoughts? #views.py class LocationDetail(View): def post(self, request, locationname): current_user = request.user user_profile = Profile.objects.get(user_id = current_user) form = PostCreate() found_location = Location.objects.get(name = locationname) context = {"found_location": found_location, "form": form} if request.method == "POST": post_author = user_profile.user_id post_title = request.POST['title'] post_content = request.POST['content'] print(post_author) print(post_title) print(post_content) if form.is_valid(): Post.objects.create( title = post_title, content = post_content, author_id = post_author, ) form.save() return render(request,'location-detail.html', context) #forms.py + models.py class PostCreate(ModelForm): class Meta: model = Post fields = ['title', 'content'] class Profile(Model): user = models.OneToOneField(User, on_delete=models.CASCADE) name = models.CharField(max_length = 30) profile_location = models.CharField(max_length = 80, blank=True, null=True) join_date = models.DateTimeField(auto_now_add=True) def __str__(self): return self.name class Post(Model): author = models.ForeignKey(Profile, on_delete=models.CASCADE, related_name="posts") title = models.CharField(max_length = 30) content = models.CharField(max_length=300) created_at = models.DateTimeField(auto_now_add=True) def __str__(self): return f'{self.author} - … -

Django InlineFormset: Size based on number of models
I am creating a gradebook app. With the following models: class Student(models.Model): student_id = models.IntegerField() first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) class Component(models.Model): CATEGORY_CHOICES = [ ('QZ', 'Quiz'), ('AS', 'Assignment'), ('TS', 'Test'), ] name = models.CharField(max_length=50) category = models.CharField( max_length = 2, choices = CATEGORY_CHOICES, default='AS', ) due_date = models.DateField() grade_total = models.PositiveIntegerField() class Score(models.Model): value = models.PositiveIntegerField() component = models.ForeignKey(Component, on_delete=models.CASCADE) student = models.ForeignKey(Student, on_delete=models.CASCADE) How can I populate a formset based on the number of students with a Component instanced?
