Problem
The
Naming/PredicatePrefixtodo entry excluded six files so that predicate methods could keep theiris_/has_prefixes.Solution
Rename the offenders and remove the exclusions. Purely mechanical, no behaviour changes:
is_logged_in?→require_loginandhas_access?→require_accessinApplicationController(these redirect rather than return a boolean, so the predicate prefix was misleading anyway)Workshop#has_host?→host?,Workshop#has_valid_host?→valid_host?is_prefix, e.g.is_admin_or_organiser?→admin_or_organiser?,is_chapter_organiser?→chapter_organiser?user.is_admin?calls are untouched: that method is generated dynamically by Rolify, so there is no definition for the cop to flag.Split out from #2768; independent of the other RuboCop PRs.
