# Review a controller file to make sure using simplified syntax for render.

# See the best practice details here http://rails-bestpractices.com/posts/62-simplify-render-in-controllers.
#
# Implementation:
#
# Review process:
# check all render method commands in controller files,
# if there is a key 'action', 'template' or 'file' in the argument,
# then they should be replaced by simplified syntax.
