Auto pre-fill form Django

问题

To pre-fill form fields in Django using the initial parameter, you can modify your OrderCreateForm in your Django forms.py like this:

class OrderCreateForm(forms.ModelForm):
    class Meta:
        model = Order
        fields = ['first_name', 'last_name', 'email', 'address', 'postal_code', 'city']

    def __init__(self, *args, **kwargs):
        super(OrderCreateForm, self).__init__(*args, **kwargs)
        if self.instance:
            # Pre-fill the form fields with data from the User class
            self.fields['first_name'].initial = self.instance.user.first_name
            self.fields['last_name'].initial = self.instance.user.last_name
            self.fields['email'].initial = self.instance.user.email

This code ensures that the first_name, last_name, and email fields in your order form are pre-filled with the corresponding data from the User class when forming the order form.

通过在创建表单实例时使用 initial 参数来传递“预填充”数据。

form = OrderCreateForm(initial={
    'first_name': user.first_name,
    'email': user.email,
})
英文:

Pass your "pre-fill" data using the initial argument when creating your form instance

form = OrderCreateForm(initial={
    'first_name': user.first_name,
    'email': user.email,
})
