I realize that, but the exception is of the
ActiveRecord:StatementInvalid class, which I should be able to catch
in
the controller with a rescue clause. But, I am not getting this to
work
at the moment. I thought that this should at least produce some out
put
but it never does:
def create
@entity = Entity.new(params[:entity])
...
respond_to do |format|
...
end
end
rescue => my_exception
puts "Rescue clause invoked!"
puts my_exception
end
For now, all I want is to see the rescue clause invoked, but it is
not.
have I put this clause in the wrong place? Am I specifying it wrong?
You can try "rescue Exception" which rescues from all exceptions, not
just ones which inherit from StandardError. (rescue without an
explicit error class *only* rescues from StandardExceptions and error
classes which derive from it):

Also - I believe this only works in 1.8.6 and above, so if you're
still on 1.8.5 I'd recommend an upgrade.
