Field 'id' expected a number but got <QuerySet [<Department: GEE>]>
I can't find the mistake here. I saw some similar questions but still can't fix it. here is my models.py class Department(models.Model): name = models.CharField(max_length=100) class CustomUser(AbstractUser): department = models.ManyToManyField(Department, blank=True) class Student(models.Model): user = models.OneToOneField(CustomUser, on_delete=models.CASCADE, primary_key=True) department = models.ManyToManyField(Department, blank=True) forms.py class StudentRegisterForm(UserCreationForm): class Meta(UserCreationForm): model = CustomUser fields = ['department', ..] widgets = {'department': forms.CheckboxSelectMultiple()} def __init__(self, *args, **kwargs): super(StudentRegisterForm, self).__init__(*args, **kwargs) self.fields['department'].required = True def clean_department(self): value = self.cleaned_data.get('department') if len(value) > 1: raise forms.ValidationError("You can't select more than one department!") return value def save(self, commit=True): user = super().save(commit=False) user.save() student = Student.objects.create(user=user) student.department.add(self.cleaned_data.get('department')) <-- got error on this line return (user, student) When the CustomUser object is created, the Student object will also be created within save method. But for some reasons it gave me an error TypeError: Field 'id' expected a number but got <QuerySet [<Department: GEE>]>. Noticed that the Department objects were created within admin panel and also the department field within the Student model works just fine if I create it inside admin panel. -

What is the better way to have Flutter app consume Python code?
The easier approach seems to be using Python as api(django/flask), but has anyone explored the starflut package and how it can be used to consume Python code. Saw an earlier question also on this but not much helpful responses on this? Import python module in flutter using starflut. Please share your experiences if you have tried this out and the limitations and approach for this. -

How can I let my users update their post through a modal in django?
I have a view that allows users to update their post: class UpdatePostView(UpdateView): model = Post template_name = 'posts/post_update.html' form_class = PostUpdateForm success_url = '/posts' def form_valid(self, form): form.instance.author.user = self.request.user return super(UpdatePostView, self).form_valid(form) def get(self, request, *args, **kwargs): self.object = self.get_object() if self.object.author.user != request.user: return HttpResponseRedirect('/') return super(UpdatePostView, self).get(request, *args, **kwargs) Via a form to be rendered to a template: class PostUpdateForm(forms.ModelForm): class Meta: model = Post fields = ['content', 'image', 'category'] And the template itself: <form method="post" enctype="multipart/form-data"> {% csrf_token %} {% for field in form %} {{ field }} {% endfor %} <button type="submit" value="submit">Update Post</button> </form> It is working okay but what I would like to do is, instead of sending the user to a separate page to update their post, allow them to update via a modal on the same page as their post.

DJango getting static bootstrap stylesheet to apply in view
I am scratching my head on this because none of this is making sense. I am running a Django project in dev mode. I have a base.html that I include in many of my pages. Here is my file structure: Here is the simple base.html code: <!doctype html> <html lang="en"> <head> <!-- Required meta tags --> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <!-- Bootstrap CSS--> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous"> <title>RAHQ Locations {% block head_title %} {% endblock %}</title> </head> <body style="background-color: #26272b; color: #fff"> {% include 'navbar.html' %} <div class='container-fluid'> {% block content %} {% endblock %} </div> {% include 'js.html' %} <br> <br> {% include 'footer.html' %} </body> </html> Everything is working PERFECT like this. But I want to make changes to the bootstrap css, so I download the bootstrap css file, rename it to styles.css, and place it in my static folder. so I replace the bootstrap href with everything I can to access my static styles.css I follow all the online guides that tell me to tweak my settings.py and url.py to allow the use of static files.

Changing the column header of a table in a postgres database
I am trying to rename a column in my database. I did heroku pg:psql ALTER TABLE discounts_discount RENAME COLUMN percentagediscountm TO percentagediscount And that had no impact.

I tried making the change using make migrations and migrate but then got this error. django.core.exceptions.FieldDoesNotExist: discounts.discount has no field named 'percentagediscountm' I am really trying to avoid having to drop my database or rolling back Heroku to an earlier build. -

I will summarize here the scope of what I need, otherwise it would be too extensive.
