how can i implement django input form with the default values

writing an online store
I have a form to add items to cart with different quantities.
I have implemented this through "TypedChoiceField":

class CartAddProductRetailForm(forms.Form):

    quantity = forms.TypedChoiceField(
        choices=PRODUCT_RETAIL_QUANTITY_CHOICES,
        coerce=int,
        label='quantity',
    )

But it looks ridiculous.

Can you tell me how to implement it with a "CharField" or "DecimalField" with a default ‘1’ value.

quantity = forms.DecimalField(max_value=999, min_value=1, )

Thanks!

>Solution :

Use Form.initial (docs).

#when instantiating your form
quantity = forms.DecimalField(max_value=999, min_value=1, initial={'quantity':1})

or

#when defining your form
class CartAddProductRetailForm(forms.Form):

    quantity = forms.DecimalField(
        choices=PRODUCT_RETAIL_QUANTITY_CHOICES,
        coerce=int,
        label='quantity',
        initial=1,
    )
