Hi all
I'm trying to make one of my first apps running but always getting weird
errors Attribute/Type for models.DecimalField as well as for DateField.
In case I want to store anything into sqlitedb I always get:
TypeError: 'datetime.datetime' object is unsubscriptable, same for
Decimal/int
For the case I already have any records in db and just want to display them
in admin interface:
Request Method: GET Request URL: http://127.0.0.1:8000/admin/energie/el/
Django
Version: 1.5 Exception Type: AttributeError Exception Value:
'Decimal' object has no attribute 'encode'
