I am calling commit, right after updated those two values.
Any suggestion on what else to check?
what is the exact column type given to this column, are there any
event.listen() things going on, and also what does a repr() of the
object's __dict__ look like?
in particular, Python has a really sneaky issue where if you happen to
have an errant comma:
x = "foo" ,
you get:
("foo", )

When I try to update a row using ORM in the following way, it
shows the following error:
InterfaceError: (InterfaceError) Error binding parameter 0 -
probably unsupported type. u'UPDATE table_name SET unicode_col=?,
int_col=? WHERE table_name.id <http://table_name.id> = ?'
((u'abcd',), 1, 2)
I suspect the problem is that the value corresponding to
unicode_col is (u'abcd',) as opposed to a simple u'abcd'.
that is the problem.
Here is how I update the database:
1) I first query it and obtain an object representing the row
that I need --> file_row
2) I perform some checks and change the values -->
file_row.int_col = 1 followed by file_row.unicode_col = u"abcd"
3) I call commit on the session
looks fine, so, I'd imagine that somehow that unicode_col =
u'abcd' is not what it seems. Either that's not what's there or
something is interfering with it after the fact.
I am pretty sure the problem is not the original type of value of
the unicode_col since the following succeeds without error:
query(TableName).filter(TableName.id == file_row.id
<http://file_row.id>).update({'unicode_col': u"abcd", 'int_col': 1})
Any idea how to fix the error?
Thanks
