Re: Initial data doesn't go complelely in the modelformset

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

in line 38 i have that print statement, it's output is at the top , I dont know why that initial data is not going into that model formset.

actually one data the PAN_ID actually went into the modelform, but the checkbox's "checked" didnt. You can see the html of the formset and the checkbox field doesnt has a checked.
