Ruby on rails, how to return the number of days of objects created over this period of time

Question

Say I have channela has many entries. This channel may contain entries for many users daily. I want to report how many records there were during the week, but I want to show how many days the record was created. Therefore, I do not want to show how many records were created this week, how many days the recording took.

Example:

channel.entries.for_week(current) returns all records that were made this week.

I just want to return the number of days that were made for this channel. Does anyone have a good solution for this?
