Hello,
I have found one solution to set an desired arbitrary order to the Order
Form fields. The solution involved setting an alternative OrderForm class
for the checkout process. And, inside that new class, edit the list
field_order, an attribute of OrderForm.
To do this I've created a file checkout.py inside /app/app/ folder. Then
copied to the new file some parts of the original "class OrderForm" from
cartridge/shop/forms.py. At the end, the field:order list of the form is
populated on the desired order. Fields not included in field:order will be
shown on its default position.
import cartridge.shop.forms
class OrderForm(cartridge.shop.forms.OrderForm):
@classmethod
def preprocess(cls, data):
print("""
A preprocessor for the order form data that can be overridden
by custom form classes. The default preprocessor here handles
copying billing fields to shipping fields if "same" checked.
""")
for field in data:
print("field:",field)
if data.get("same_billing_shipping", "") == "on":
for field in data:
bill_field = field.replace("shipping_detail",
"billing_detail")
if field.startswith("shipping_detail") and bill_field in
data:
data[field] = data[bill_field]
# Change the order of the fields of the OrderForm
# Ex.: Country and city will be the first and second fields.
cls.field_order = ['billing_detail_country', 'billing_detail_city']
return data
and edited /app/app/settings.py
# Set an alternative OrderForm class for the checkout process.
# SHOP_CHECKOUT_FORM_CLASS = 'cartridge.shop.forms.OrderForm'
SHOP_CHECKOUT_FORM_CLASS = 'app.checkout.OrderForm'
