I would like to escape the data from a model attribute...
Here a example:
Old model:
-------------------------------------------------------------
class Page(models.Model):
...
name = models.CharField()
...
-------------------------------------------------------------
I have changed the model to this:
-------------------------------------------------------------
class Page(models.Model):
...
__name = models.CharField(
db_column='name'
)
def __get_name(self):
return escape(self.__name)
def __set_name(self, data):
self.__name = data
name = property(__get_name, __set_name)
...
-------------------------------------------------------------
Now, i have a problem :(
This works, fine:
page = Page.objects.all()[0]
print page.name
But here i get a 'FieldDoesNotExist' Traceback:
print Page.objects.values("name")
The complete traceback:
-------------------------------------------------------------
Traceback (most recent call last):
File "./PyLucid_shortcuts_test.py", line 24, in <module>
print Page.objects.values("name")
File "./django/db/models/query.py", line 108, in __repr__
return repr(self._get_data())
File "./django/db/models/query.py", line 482, in _get_data
self._result_cache = list(self.iterator())
File "./django/db/models/query.py", line 597, in iterator
fields = [self.model._meta.get_field(f, many_to_many=False) for f in
self._fields]
File "./django/db/models/options.py", line 131, in get_field
raise FieldDoesNotExist, '%s has no field named %r' % (self.object_name,
name)
django.db.models.fields.FieldDoesNotExist: Page has no field named 'name'
-------------------------------------------------------------
Why?
Is this a bug?
