Hi,
I have a problem when i perform a select() on a model with an
"ReferenceProperty" Field.
I'am getting this error:
*("'ReferenceProperty' object has no attribute 'startswith'",)*
*
*
related but nor sure it's the same:
https://groups.google.com/forum/?fromgroups#!topic/web2py/M7civkMWRyo
and it occurs at this line in dal.py:
def represent(self, obj, fieldtype):
* field_is_type = fieldtype.startswith*
if isinstance(obj, CALLABLETYPES):
obj = obj()
if isinstance(fieldtype, SQLCustomType):
return fieldtype.encoder(obj)
if isinstance(obj, (Expression, Field)):
raise SyntaxError("non supported on GAE")
if self.dbengine == 'google:datastore':
if isinstance(fieldtype, gae.Property):
return obj
Now, at the time the exception occurs the Fieldtype is of type
"ReferenceProperty" which does not have a "startswith" attribute.
When i move this line to another position, the error is gone.
But i'm not familiar enough with the code to be sure this i the correct
solution.
Maybe the source of the problem lies somewhere else..
this works:
def represent(self, obj, fieldtype):
if isinstance(obj, CALLABLETYPES):
obj = obj()
if isinstance(fieldtype, SQLCustomType):
return fieldtype.encoder(obj)
if isinstance(obj, (Expression, Field)):
raise SyntaxError("non supported on GAE")
if self.dbengine == 'google:datastore':
if isinstance(fieldtype, gae.Property):
return obj
*field_is_type = fieldtype.startswith*
Any idea?
thanks!
