[Zope] Use of mapply for calling ZSQL method
Mon, 22 Jul 2002 21:15:51 +0200
I need to call a ZSQL method from a product and after searching the
archives it seems the best solution is to make use of mapply as
directed in cduncans article which deals with this in zopeLabs:
Unfortunately, due to my lack of experience with Python, I cannot get
the syntax to work and would appreciate some advise.
Here's what I'm trying to do. Please don't laugh :-(
def __init__(self, sql_method_name):
def check_db(self, val1, val2, val3):
"""Check database to determine if item already exists"""
object = getattr(self.aq_parent, self.data_source_id)
res = mapply(object, (arg1=val1,arg2=val2, arg3=val3),
REQUEST, call_object,1, missing_name,
dont_publish_class, REQUEST, bind=1)
The ZSQL method I'm trying to call (sql_method_name) accepts 3
optional arguments, represented here by arg1, arg2, arg3 and returns
true or false depending on whether an item with the values supplied
can be found within the DB.
I'm sure it's pretty obvious where I'm going wrong.
