Store multiple choice field in db using Django

I have three models class as below.

from django.forms import ModelForm


RATING_CHOICES = ((1, "Weak"), (2, "Average"), (3, "Good"), (4, "Excellent"))


class Question(models.Model):
    text = models.CharField(max_length=100)
    
    def __str__(self):
        return self.text


class Teacher(models.Model):
    name = models.CharField(max_length=50)

    def __str__(self):
        return self.name


class Answer(models.Model):
    question = models.ForeignKey(Question, on_delete=models.CASCADE)
    teacher = models.ForeignKey(Teacher, on_delete=models.CASCADE)
    answer = models.IntegerField(choices=RATING_CHOICES, default=1)

in the template I have access to my fields in this way:

  {% csrf_token %}
    <select name="teacher_selected">
      {% for teacher in teacher %}
        <option value="{{teacher}}">{{teacher}}</option>
        {% endfor %}
    </select>

  {% for question in question %}
      <ol>{{ question.text }}</ol>
      {% for choice in rating_choices %}
        <input type="radio" name="question_{{question.id}}" value="{{choice.0}}">{{choice.1}}
      {% endfor %}

  {% endfor %} <br>

  <input type="submit" value="Vote">
</form>

Now I know how to get the value of Teacher class teacher = request.POST.get(‘teacher_selected’), but I do not know how to store answers since it is a little different compare to teacher.
I asked this question in StackOverFlow but did not get the clear answer. They just gave me hints. For example, use formset or linking part 4 of Django documentation.
I need a proper views.py for my codes.
