Session 5 & 8

[Jia Ying]

Hi,

I have questions regarding these 2 sessions.

Session 5 Step 2: How do we create a template that accommodates the plural forms?

Session 8: How do we make use of a guard to display a message like "No schedule" if the user requests to display the schedule when it's empty?

I tried this but it didn't work:
Q: Display

A: schedule #empty? true % No schedule.

A: ${ schedule display }

Are there other types of guards besides same? and id! ?
