django form default value

README.md

Objetivo: definir um valor default para um campo, simples né?

Pega a visão:

• __init__

class MyForm(forms.ModelForm):

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

        self.fields['preco'].initial = 0.0

• initial na views

def my_create(request):
    my_form = MyForm(request.POST or None, initial={'preco': 0.0})

https://docs.djangoproject.com/en/4.1/ref/forms/api/#initial-form-values

• Apelando com Javascript

document.getElementById("id_preco").defaultValue = "0"
