Populating a drop-down from Database in Django - django

Question

Hi so basically I am trying to populate a drop-down menu from a database I currently have. This will enable a 'Teacher' to select a 'Student' they input grades for. I am struggling to understand any of the tutorials online due to most of them being for django 1.9 whereas I am using 2.1.
Please if you could help, it would be much appreciated.
Template:
<form action="{% url 'subject1_view' %}" method="post">
{% csrf_token %}
<div class="form-group row">
<label class="col-2 col-form-label" for="information">Student Name</label>
<div class="col-10">
<form method="POST">
<select class="form-control" name="student_name" id="information">
{% for ?? %}
<option value="{{ ?? }}">{{ ?? }}</option>
{% endfor %}
</select>
</form>
</div>
</div>
URLs:
from django.urls import path, include
from . import views
urlpatterns = [
path('teacher_login', views.teacher_login, name='teacher_login'),
path('t_dashboard', views.t_dashboard, name='t_dashboard'),
path('subject1_view', views.subject1_view, name='subject1_view'),
path('loguserout', views.loguserout, name='loguserout'),
]
Views:
def subject1_view(request):
if request.method == 'POST':
student_name = (request.POST.get('student_name'))
current_grade = (request.POST.get('current_grade'))
previous_grade = (request.POST.get('previous_grade'))
target_grade = (request.POST.get('target_grade'))
incomplete_homework = (request.POST.get('incomplete_homework'))
behaviour_rank = (request.POST.get('behaviour_rank'))
i = Subject1(student_name=student_name, current_grade=current_grade, previous_grade=previous_grade,
target_grade=target_grade, incomplete_homework=incomplete_homework, behaviour_rank=behaviour_rank)
i.save()
return render(request, 'Teacher/dashboard.html')
else:
return render(request, 'Teacher/subject1.html')
Models:
from django.db import models
from Student.models import Student
# Create your models here.
class Subject1(models.Model):
student_name = models.ForeignKey(Student, on_delete=models.CASCADE)
current_grade = models.CharField(max_length=2)
previous_grade = models.CharField(max_length=2)
target_grade = models.CharField(max_length=2)
incomplete_homework = models.CharField(max_length=2)
behaviour_rank = models.CharField(max_length=2)
def __str__(self):
return self.student_name

Use a Django Form, and populate the choices on the form's init method:
class SelectForm(forms.Form):
student = forms.ChoiceField(widget=forms.Select(attrs={'class': 'form-control'}))
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.fields['student'].choices= [(student.id, student.name) for student in Student.objects.all()]
Template:
<form action="{% url 'subject1_view' %}" method="post">
{% csrf_token %}
<div class="form-group row">
<label class="col-2 col-form-label" for="information">Student Name</label>
<div class="col-10">
{{ form }}
</div>
</div>
</form>
Also add add form to context from View.
