Overview

Enforces the consistent use of action filter methods.

The cop is configurable and can enforce the use of the older something_filter methods or the newer something_action methods.

IMPORTANT: This cop is deprecated. Because the ‘*_filter` methods were removed in Rails 4.2, and that Rails version is no longer supported by RuboCop Rails. This cop will be removed in RuboCop Rails 3.0.

Examples:

EnforcedStyle: action (default)

# bad
after_filter :do_stuff
append_around_filter :do_stuff
skip_after_filter :do_stuff

# good
after_action :do_stuff
append_around_action :do_stuff
skip_after_action :do_stuff

EnforcedStyle: filter

# bad
after_action :do_stuff
append_around_action :do_stuff
skip_after_action :do_stuff

# good
after_filter :do_stuff
append_around_filter :do_stuff
skip_after_filter :do_stuff
