In line 58 you can see me adding "print_report_check":True,
my form
class PrintReportModelForm(ModelForm):
print_report_check = forms.BooleanField(widget=forms.CheckboxInput(),
required=False)
class Meta:
fields = ["PAN_ID", "print_report_check"]
model = User
widgets = {"PAN_ID": forms.HiddenInput()}
def __init__(self,*args, **kwargs):
super().__init__(*args, **kwargs)
self.fields["PAN_ID"].disabled = True
# self.fields["print_report_check"].initial = True
def save(self, commit=True):
logger.info(" Method not meant to save anything ")
pass
