In a rails application,
I have a set_lang() and a write_to_log() method in
app/controllers/application.rb

set_lang() calls write_to_log().
Nothing happens. I should expect that write_to_log is either called or
an exception is thrown. However, it seems that it is silently ignored.
To prove this I called write_to_log00(), which does not exist. Still
the same behavior.

Is this normal?
Is there a workaround?
