If I turn warnings into errors, the problem is still the same:
1) where the error occured as the code path in traceback is not
pointing to the place where select() has been bound with values
that would suggest your code has some less typical form where you are
creating a select() object in some distant place, storing it, and then
invoking it in some other place entirely? If so, you'd have to track
that. Bound parameter values aren't touched until execution time.
Turning on SQL logging will illustrate the statement being sent and you
can use some basic intuition to point it to what code is causing it.
2) you don't know what was the value

Hey,
you dan do:
import warnings
warnings.simplefilter('|error|')
This will raise an exception. and give you a stacktrace on where
the Unicode warnign happened.

Hi,
it happened to me many times during development, mainly when used
custom column types, that I passed wrong type of value to the query.
Then the the following warning was emitted:|
||
SAWarning: Unicodetype received non-unicode bindparam value
|
The problem with such warning is it does not say
1) were the problem occurred (the line number points to somewhere
in sqlalchemy and not to my application)
2) what was the value which caused the problem ( repr() of that
value would be nice to have)
I always had to hack sqlalchemy/sql/sqltypes.py and add print
value before the warning is emitted to actually see what was wrong.
Is there any convenient way how to solve such issue?
