Hi all,
I just found out some weird thing working with @with_transaction, and was
wondering whether I'm doing something wrong or it's expected Python
behavior.
I have a class method that receives some parameters.
In the method, I have a @with_transaction function to write things on the
database, using the method's input parameters (through a closure).
It works fine, unless the function itself has some code that writes to a
variable named like one of the parameters.
In this case, I get an unbound local variable error when trying to use the
input parameter.
I guess this is just standard Python closures behavior, but wanted to check
with you guys anyway:
def save_stuff(self, t_action, t_id, t_name):
@with_transaction(self.env)
def do_save_stuff(db):
cursor = db.cursor()
if t_action == 'ADD':
# "Offending" row
t_id = self.get_next_id()
cursor.execute("""
INSERT INTO stuff (id, name)
VALUES (%s,%s)
""", (t_id, t_name))
else:
# I get an error here for unbound local t_id variable
# unless I comment out the "t_id = self.get_next_id()" row
above
cursor.execute("""
UPDATE stuff
SET name = %s
WHERE id = %s
""", (t_name, t_id))
Ciao,
Roberto
