I''m trying to generate a report for the average number of calls a
person
makes per-day. The following generates the correct list, but if a user
didn''t make any calls a certain day it doesn''t show up.
from_date = Time.now.at_beginning_of_month.to_s(:db)
to_date = Time.now.tomorrow.to_s(:db)
ave_calls = @current_user.calls.average(:num_of_calls,
:group => "DATE(calls.start_time_stamp)",
:conditions => ["calls.created_at BETWEEN ? AND ?",
from_date, to_date])
What is the best way of doing this? An example I have right now, I have
data from August 3rd til Today, no calls were made August 2nd or August
1st. The list comes back and starts at the 3rd.

Its just reporting the DB data in an aggregated format. Merge the returned ave_calls with a list built out of an iteration of from_date to to_date by day to fill the gaps. -- Posted via http://www.ruby-forum.com/.

So I went into my debugger to see what was happening. irb(#<ReportsController:0x47b7524>):008:0> call_aves[0] => [Sat Aug 01 00:00:00 -0400 2009, 0] As I go up in the array, i notice it''s only incrementing by seconds, not by days. For example: irb(#<ReportsController:0x47b7524>):009:0> call_aves[30] => [Sat Aug 01 00:00:30 -0400 2009, 0] How do I get this to go up by the day, not the second? -- Posted via http://www.ruby-forum.com/.
> > How do I get this to go up by the day, not the second?Change your grouping function in the SQL, rather than DATE(calls.start_time_stamp) can you use just the day of the month portion? Perhaps DAYOFMONTH(calls.start_time_stamp) (or just DAY(calls.start_time_stamp)) as long as you''re selecting within a month, like start of month to current date. -- Posted via http://www.ruby-forum.com/.
