Hi all,
I have an event containing a datetime and want to see if that datetime
is in the past.
I have a method in event
def future_event?
if self.start <= DateTime.now()
return true
end
false
end
on an event I can the do event.future_event?
This results in You have a nil object when you didn''t expect it!
The error occurred while evaluating nil.<
The strange thing is that self is definatly not nil? Is this a problem
with DateTime.now()?
regards,
Stijn

self.start indeed returns a nil value but the strange this is that it is when I look at the self.attributes -> start in the debugger it is correctly filled in. Is start a name you can''t use in rails?

I changed the name of ''start'' to ''begin'' and it works now in debug.
