UpdateView Decimal Field Initial Value

[tango ward]

Hi,

I am working on an UpdateView of a form. I am having hard time displaying the initial value of grades per subject. I can display the subjects fine in the template, however I can't display the grades using the DecimalField. If change DecimalField to ModelChoiceField in forms.py, I can view the grades in a drop down menu in template but this is not what I want. I want the user to be able to edit using DecimalField.

forms.py

class GradeUpdateForm(CrispyFormMixin, forms.ModelForm):
s_name = forms.ModelChoiceField(queryset=Subject.objects.none(), empty_label=None)
final_grade = forms.DecimalField(widget=forms.NumberInput(attrs={'style':'width:80px'}), decimal_places=2, max_digits=5,)
class Meta:
    model = SGrade
    fields = [
        's_name',
        'final_grade',
    ]

I tried playing around with for loop in my views but no good.

views.py
class SchoolDashboardGradesUpdateView(SchoolStudentMixin, UpdateView):
template_name = 'education/dashboard/grades_update.html'
model = SubjectGrade
form_class = GradeUpdateForm

# def get_object(self):
#     return get_object_or_404(Recipient, pk=self.kwargs['pk'])

def get(self, request, *args, **kwargs):
    self.object = None
    form_class = self.get_form_class()
    form = self.get_form(form_class)
    form.fields['subject_name'].queryset = Subject.objects.filter(
                                                                sgrade__recipient__id=self.kwargs.get('pk'),
                                                                sgrade__status='approved').values_list('name', flat=True)
    form.fields['final_grade'].queryset = SGrade.objects.filter(
                                                                    recipient__id=self.kwargs.get('pk'),
                                                                    status='approved').values_list('final_grade', flat=True)
student = Student.objects.get(id=self.kwargs.get('pk')
for x in student.sgrade_set.all():
 if x.status == 'approved':
  forms.fields['final_grade'].initial = x.final_grade

for st in student.subjectgrade_set.all():
            if st.status == 'approved':
                test_dict[st.subject.name] = st.final_grade

        print test_dict
        for key, value in test_dict.iteritems():
            if key in subject_names:
                form.fields['final_grade'].initial = value

I also tried putting the keys and values in a dictionary and in my html

template

<!-- Before the test_dict variable in views.py -->

<tbody>
      {% for instance in form.subject_name.field.choices %}
        <tr>
         <td>{{instance.1}}</td>
         <td>{{form.final_grade}}</td>
        </tr>

      {% endfor %}

    </tbody>
test_dict = {}

<!-- After the test_dict variable in views.py --)
{% for key, value in test_dict.iteritems %}
            <tr>
              <td>{{key}}</td>
              <td></td>
              <td></td>
              <td></td>
              <td></td>
              <td><input type="number" name="first_quarter_grade" value="{{value}}" style="width:120px"></td>
            </tr>
          {% endfor %}

Problem with the second test in HTML, I can't assign the value of test_dict's value in form.field['final_grade']

       

Apologies for the long post.

All suggestions are highly appreciated.

Thanks,

J
