Need 'return' statement following 'fail' call in a Ruby method? -
i got following code rails tutorial:
def do_something # code here.... if @user.blank? fail notauthenticatederror return end # more code here... end
is return
statement necessary, or fail
call sufficient stop rest of code in method running? perhaps depends on how notauthenticatederror
handled?
no, don't need return.
def do_something puts "start" fail notauthenticatederror puts "this doesn't print" end
that code never last line.
