Changing variables on Left hand side.

How do i take changing-variables on left hand side? I am trying it like this, but gives me an error that "expected end" at line no. 50.

Abc.all.each do |a|   "@some_array_#{a.name}" = do_something --line number 50 end

Is there any way to achieve this?

In this particular case you can use instance_variable_set. However i'd usually not do this - I'd probably build up a hash instead.

Yups, I have used hash. That is much more clearer as well in code.:slight_smile:

Thanks.
