I am working on a learning platform. I want to be able to track user progress of the chapters completed. I cerated a new model and inserted it into the html using a form. However when I submit, I keep getting a TypeError with the specifics that “Field ‘id’ expected a number but got <QueryDict: {‘csrfmiddlewaretoken’: [‘YMvOO6ZYGWVVfxfgoFLVEanZ9zK70CrqlRIx5Y2LOkbzH8Mx3UHPlQYczqLbq1Qt’], ‘chapter’: [‘2’], ‘completed’: [‘on’], ‘student’: [‘1’]}>“

I tried converting all the variables I was using to identify the user, student and chapter to their primary keys but I got even more complicated error. If there is an easier way to track the progress or a tutorial on a way to do it, please share.

Here’s what I tried

This is he StudemtProgress Model

class StudentProgress(models.Model):
    student = models.ForeignKey(
        Student, on_delete=models.CASCADE, related_name="student_progress"
    )
    chapter = models.ForeignKey(
        Chapter, on_delete=models.CASCADE, related_name="student_progress"
    )
    completed = models.BooleanField(default=False)

    

This is the form. Some of the code is to pick only the current logged in user and the chapter of th page that it is being displayed.

class StudentProgressForm(forms.ModelForm):
    class Meta:
        model = StudentProgress
        fields = ("chapter", "completed", "student")
        # widgets = {
        #     "student": forms.HiddenInput(),
        # }

    def __init__(self, user, student_slug, chapter_slug, *args, **kwargs):
        super(StudentProgressForm, self).__init__(*args, **kwargs)
        student_queryset = Student.objects.filter(user=user, student_slug=student_slug)

        if student_queryset.exists():
            self.instance.student = student_queryset.first()
        else:
            self.instance.student = None

        if student_queryset.exists():
            self.fields["student"].initial = student_queryset.first()

        current_chapter = Chapter.objects.filter(chapter_slug=chapter_slug).first()
        self.fields["chapter"].initial = current_chapter

    def get_current_chapter(self, current_chapter_slug):
        return Chapter.objects.filter(chapter_slug=current_chapter_slug).first()

This is the logic I used in the views.py file

    if request.method == "POST":
        form = StudentProgressForm(
            request.POST,
            instance=single_chapter,
            student_slug=student_slug,
            chapter_slug=chapter_slug,
        )
        if form.is_valid():
            form.save()
            return redirect("user_dashboard")

    else:
        form = StudentProgressForm(
            user=request.user,
            instance=single_chapter,
            student_slug=student_slug,
            chapter_slug=chapter_slug,
        )

And lastly the html file has this form

<form method="post">
      {% csrf_token %}
      {{ form.as_p }}
      <button type="submit">Submit</button>
    </form>
