I modified the core product/models.py code to add some print
statements:
~~~~~~~~~~~~~~~~~
def get_subtypes(self):
# If we've already computed it once, let's not do it again.
# This is a performance speedup.
if hasattr(self,"_sub_types"):
return self._sub_types
types = []
try:
for key in config_value('PRODUCT', 'PRODUCT_TYPES'):
app, subtype = key.split("::")
try:
subclass = getattr(self, subtype.lower())
print "########### app = " + app
print "########### subtype = " + subtype
print "########### subclass = " + str(subclass)
gettype = getattr(subclass, '_get_subtype')
print "########### gettype = " + str(gettype)
print ""
subtype = gettype()
if not subtype in types:
types.append(subtype)
except models.ObjectDoesNotExist:
pass
except SettingNotSet:
log.warn("Error getting subtypes, OK if in SyncDB")
self._sub_types = tuple(types)
return self._sub_types
~~~~~~~~~~~~~~~~~
If i load /admin/product/product i get this kind of list for existing
products ("Base Product" is the name of the product I created from a
plain Product and used as a custom order product):
########### app = product
########### subtype = ConfigurableProduct
########### subclass = robot-attack
########### gettype = <bound method ConfigurableProduct._get_subtype
of <ConfigurableProduct: robot-attack>>
########### app = product
########### subtype = CustomProduct
########### subclass = CustomProduct: Base Product
########### gettype = <bound method CustomProduct._get_subtype of
<CustomProduct: CustomProduct: Base Product>>
########### app = product
########### subtype = CustomProduct
########### subclass = CustomProduct: Base Product
########### gettype = <bound method CustomProduct._get_subtype of
<CustomProduct: CustomProduct: Base Product>>
########### app = product
########### subtype = CustomProduct
########### subclass = CustomProduct: Base Product
########### gettype = <bound method CustomProduct._get_subtype of
<CustomProduct: CustomProduct: Base Product>>
When I try to add a new custom product from my MyCustomProduct class,
I error out on MyCustomProduct' object has no attribute '_get_subtype'
and get this:
########### app = my_app
########### subtype = MyCustomProduct
########### subclass = Test special product
