django - Django Forms AttributeError 'NoneType' object has no attribute 'disabled'

Question

I keep having trouble with a custom Django form that I am trying to implement. I really didn't know any way for getting the data from the frontend besides trying to pull the data by force through request.POST.get(), but once I started doing that I ran into an AttributeError that kept saying 'NoneType' object has no attribute 'disabled', and the error referenced the form.save() line as the problem in my views.py. Here is the code for the views.py

@login_required
def volunteer_instance_creation(request):
    form = VolunteerInstanceForm(request.POST or None, request.FILES)
    values_dict = {
        "organization": request.POST.get('organization'),
        "supervisor_Name": request.POST.get('supervisor_Name'),
        "supervisor_Phone_Number": request.POST.get('supervisor_Phone_Number'),
        "volunteering_Duration": request.POST.get('volunteering_Duration'),
        "volunteering_Date": request.POST.get('volunteering_Date'),
        "description": request.POST.get('description'),
        "scanned_Form": request.POST.get('scanned_Form'),
    }
    for i in values_dict:
        form.fields[i] = values_dict[i]
    if form.is_valid:
        obj = form.save(commit = False)
        obj.student_id = get_student_id(str(User.objects.get(pk = request.user.id)))
        obj.grad_year = get_grad_year(str(User.objects.get(pk = request.user.id)))
        obj.save()
        return redirect("submission_success")
    return render(request, "members_only/yes_form.html")

Here is my models.py

class VolunteerInstance(models.Model):
student_id = models.CharField(
    blank = True, 
    editable = True, 
    default = 'No Student ID Provided',
    max_length = 255
)
grad_year = models.CharField(
    blank = True, 
    max_length = 255,  
    default = 'No Graduation Year Provided', 
    editable = True
)
organization = models.CharField(
    blank = False,
    max_length = 255
)
description = models.TextField(
    blank = False, 
)
supervisor_Name = models.CharField(
    blank = False, 
    max_length = 255
)
supervisor_Phone_Number = models.CharField(
    blank = True, 
    null = True, 
    max_length = 10
)
volunteering_Date = models.DateField()
volunteering_Duration = models.FloatField()
scanned_Form = models.FileField(
    null = True,
    blank = True, 
    upload_to = 'scanned_files', 
)
approved = models.BooleanField(
    default = False, 
    blank = True
)

And here is the template that has been causing problems for me.

<form action = '.' method = "POST"> 
    {% csrf_token %}
    <div class="form-group row">
        <label class="col-sm-12 col-md-2 col-form-label">Nonprofit Agency</label>

    </div>
    <input type = "submit" class = "btn btn-success" value = "Submit" name = "submit"/> 
</form>
{% if form.non_field_errors %}
        {% for error in form.non_field_errors %}
            <p class="text-danger">{{ error }}</p>
        {% endfor %}
{% endif %}
