I have a function and two convenience functions, like this:
@defer.inlineCallbacks
def round_value_and_percent(id, value, percent):
daily = 1.
params = dict(nutidin=id, valuein=value, dvin=daily)
query = "ROUND_NUT_DV"
q_result = yield named_query_param(ctx, "nut", query, params)
// db query
rounded = {}
rounded["value"] = q_result[0][0]
rounded["percent"] = q_result[0][1]
defer.returnValue((rounded['value'], rounded['percent']))
@defer.inlineCallbacks
def round_val(id, value, rule):
"""
Return first element of round_value_and_percent
"""
defer.returnValue(round_value_and_percent(id, value, 0, rule)[0])
@defer.inlineCallbacks
def round_per(id, percent, rule):
"""
Return second element of round_value_and_percent.
"""
defer.returnValue(round_value_and_percent(id, 0, percent, rule)[1])
When I do:
result = yield round_val(1, 2, 3)
I get this: Deferred instance has no attribute '__getitem__'
Clues appreciated!
