Add fields dynamically in django ModelForm

Question

my model

class MyModel(models.Model):
    remark = models.CharField(max_length=120)
    data_1 = models.BooleanField(default=False)
    data_2 = models.BooleanField(default=False)
    data_3 = models.BooleanField(default=False)
    data_4 = models.BooleanField(default=False)

Form

class MyModelForm(forms.ModelForm):
    CHOICES= (("data_1", "data_1"),
               ("data_2", "data_2"),
               ("data_3", "data_3"),
               ("data_4", "data_4"),)
    my_choice = forms.MultipleChoiceField(choices=CHOICES, widget=forms.CheckboxSelectMultiple())
    class Meta:
        model = MyModel
        fields = ["remark"]

view

class MyView(UpdateView):
    model = MyModel
    form_class = MyModelForm
    template_name = "mytemplate.html"

    def form_valid(self, form):
        selected_choices = self.request.POST.getlist("my_choice")
        for item in selected_choices:
            form.instance.item = False
        form.instance.remarks = form.cleaned_data["remark"]
        form.instance.save()
        return super(MyView, self).form_valid(form)

what i want is, i want to take the selected choices and change its value to False by checking the checkbox and remaining must be unaffected.Please help....

This question is hard to understand and doesn't seem to have anything to do with adding fields to forms. But I think you are looking for setattr:

    for item in selected_choices:
        setattr(form.instance, item, False)
