You can't use Symbols, but you can use Regexps

szeryf · Feb 1, 20093 thanks

You can't use Symbol (although Symbol is accepted with +render+ +:action+ => +:new+), like:

assert_template :new # WON'T WORK!

But you can use Regexp, e.g.:

assert_template /new/ # WORKS OK

Note that the String matched with your Regexp is the full path to the template relative to the +view/+ directory of your app, so this will not work:

assert_template /^new$/ # WON'T WORK!

However this might:

assert_template /^employees\\/new.html.haml$/

As of v2.3.4 you can use Symbols
