Fix issue with DecimalField for Django

I'm getting the following error when trying to save a "Subscription" object via Django and DecimalFields: 02/08 09:28:37> Decimal price: 0.00 02/08 09:28:37> Decimal price = None 02/08 09:28:37> Traceback (most recent call last): File "/home/payment/payment/web/api/[login to view URL]", line 170, in create [login to view URL]() File "/home/payment/payment/lib/python2.6/site-packages/django/db/models/[login to view URL]", line 410, in save self.save_base(force_insert=force_insert, force_update=force_update) File "/home/payment/payment/lib/python2.6/site-packages/django/db/models/[login to view URL]", line 483, in save_base values = [(f, f.get_db_prep_save(raw and getattr(self, [login to view URL]) or f.pre_save(self, True))) for f in meta.local_fields if not isinstance(f, AutoField)] File "/home/payment/payment/lib/python2.6/site-packages/django/db/models/fields/[login to view URL]", line 624, in get_db_prep_save return connection.ops.value_to_db_decimal(self.to_python(value), File "/home/payment/payment/lib/python2.6/site-packages/django/db/models/fields/[login to view URL]", line 598, in to_python return [login to view URL](value) File "/usr/lib/python2.6/[login to view URL]", line 649, in __new__ "First convert the float to a string") TypeError: Cannot convert float to Decimal. First convert the float to a string Here is the code: # standard pricing #[login to view URL] = str([login to view URL]['subscription_price']) [login to view URL] = Decimal("%.2f" % (float([login to view URL]['subscription_price']))) log('Decimal price: %s' % [login to view URL]) if [login to view URL] == Decimal("0.00"): [login to view URL] = None log('Decimal price = None') Models are as follows (I only pasted the relevant DecimalField fields): class Subscription([login to view URL]): # standard month to month, year to year, etc. pricing. price = [login to view URL](default=0.00, max_digits=10, decimal_places=2, null=True, blank=True) # Price of the item we auto-create every billing cycle (0 if None) # price for extra users price_per_extra_user = [login to view URL](default=0.00, max_digits=10, decimal_places=2, null=True, blank=True, help_text="The price for extra users.") # first billing interval first_price_per_num_dmy = [login to view URL](default=0.00, max_digits=10, decimal_places=2, null=True, blank=True, help_text="The first payment's price per user") Please let me know if you know of a quick fix. I can provide SVN source code access... but most programmers shoul
