How to use 'until' and 'count' parameters to create a recurring event

[britaumich]

Hello, I can't find any documentation on using the 'until' and 'count' parameters in the recurring rules. I see a pull request Add option to end after a number of occurrances or on a date #117 opened on the same question. Could someone help me understand how to add 'until' and 'count' to the Set Schedule dialog? Or at least how to send 'until' and 'count' parameters to create a new recurring event? The hash with the rule looks like this:

"recurring"=>"{\"interval\":1,\"until\":null,\"count\":null,\"validations\":{\"day\":[0]},\"rule_type\":\"IceCube::WeeklyRule\",\"week_start\":0}"

where until and count are null.

Thank you
