Hello list :)
I'm using SQLAlchemy in a mod_python application. I'm using the
autoload=True to load the tables definition from the SQL Server
(Postgresql).
I like to do this way, and it works fine except that it takes a lot of
time and it slow down the application the first time the handler loads
(after it's cached by mod_python).
I thought to "pickle" the table definition once and reuse it later (good
idea ? bad idea ?), but I got an error when I call the .dump() method of
cPickle :
>>> tables
<open file 'blah.dmp', mode 'w' at 0xb7b02720>
>>> type(invasives)
<class 'sqlalchemy.schema.Table'>
>>> cPickle.dump(invasives, tables, 2)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
TypeError: 'NoneType' object is not callable
>>> cPickle.dump(invasives, tables)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/lib/python2.3/copy_reg.py", line 83, in _reduce_ex
dict = getstate()
TypeError: 'NoneType' object is not callable
I suspect that __getstate__ is in a class but is not a function ...
any idea ?
thanks
