It might be convenient for you to use ruby interpolations in a method
like describe. The following is equivalent to your method (you don’t
need return either - the last thing evaluated is always returned from a
method):
def describe
“#{name}#{email}#{mobile}#{category}#{other}”
end

to string, it is convention in ruby to call #to_s method on it. If you
use anything in an interpolation, ruby will call #to_s on this object
for you.
Thank you Michal, your post is at must help, however I have discovered a
new gem called fullcalendar. Do you think that with this, you can link
these id’s so that we can view each attribute in a calendar. So
basically like the day will be on the left but then I will be able to
display this persons “#{name}#{email}#{mobile}#{category}#{other}”
also on the calendar.?
