how to apply Web2py's @cache decorator to a function with multiple parameters

[Carl]

When I add @cache as below in my default.py

@cache(request.env.path_info, 60, cache.ram)
def search_user_contacts(searchText):
from applications.init.modules.user import User
user = User(globals())
contacts = user.find_contacts(searchText)
return searchText, contacts

I get a runtime error: TypeError: <lambda>() takes no arguments (1
given)

In some way I'm failing to set-up this decorator to be smart enough to
call the function with the 'searchText' parameter.

Does anyone know where I've gone wrong?

This works but doubles up on the number of functions needed. But by
calling cache.ram directly I'm able to define a lambda function that
uses the 'searchText' parameter. can anyone take this one step
further?

def search_user_contacts_cached(searchText):

from applications.init.modules.user import User
user = User(globals())
contacts = user.find_contacts(searchText)

return searchText, contacts

@service.jsonrpc
def search_user_contacts(searchText):
return cache.ram('search_contact=%s'%searchText,
lambda: search_user_contacts_cached(searchText),
60)
