Assigning a value to a Django form field in a view?

Question

Django

There is a page with a table that contains database objects. I want to make it so that when you click on a record in this table, a new window opens with a form for editing this database object. I set everything up except for displaying the existing form fields. The fact is that the form is displayed empty, and in it (logically) there should be already filled fields in order to see what you are editing. Tell me how best to pass the value from the object to the form field. I tried to create a form in the view and pass an object to it as an instance, but for some reason only text fields are pulled up.

views.py

@login_required
def EditProjectView(request):
    obj = Project.objects.get(id=request.GET.get('objId'))
    form = EditProjectForm(instance=obj, objId=obj.id)

    return render(request, 'editProject.html', {
        'form': form
    })

forms.py

class EditProjectForm(forms.ModelForm):
    class Meta:
        model = Project
        fields = [
            'name',
            'number',
            'idKontr',
            'idTip',
            'idStatus',
            'idKv',
            'description'
        ]

        widgets = {
            'idKontr': forms.Select(attrs={
                'class': 'form-control'
            }),
            'idTip': forms.Select(attrs={
                'class': 'form-control'
            }),
            'idStatus': forms.Select(attrs={
                'class': 'form-control'
            }),
            'idKv': forms.Select(attrs={
                'class': 'form-control'
            }),
        }

    objId = forms.IntegerField()

    def __init__(self, *args, **kwargs):
        super(EditProjectForm, self).__init__(*args, **kwargs)

        self.fields['objId'].widget = forms.NumberInput(attrs={'class': 'd-none', 'id': 'edit_id_field'})

        self.fields['name'].widget = forms.TextInput(attrs={'class': 'form-control'})
        self.fields['description'].widget = forms.Textarea(attrs={'class': 'form-control'})

        self.fields['name'].required = False
        self.fields['number'].required = False
        self.fields['idKontr'].required = False
        self.fields['idTip'].required = False
        self.fields['idStatus'].required = False
        self.fields['idKv'].required = False
        self.fields['description'].required = False
