RuboCop Rails v2.35.3

Bug fixes

• #1630: Fix a false positive in Rails/StrongParametersExpect when negating params[:key] with !, such as !params[:key]. (@​koic)
• #1629: Fix false positives in Rails/StrongParametersExpect when using the safe navigation operator (&.) on params[:key]. Autocorrecting params[:key]&.downcase to params.expect(:key).downcase silently changes behavior — a missing param goes from returning nil to raising ActionController::ParameterMissing. (@​lucasmazza)

RuboCop Rails v2.35.2

Bug fixes

• #1625: Fix false positives in Rails/StrongParametersExpect when using collection methods (such as delete, keys, merge, slice, dig, fetch, or transform_values) on params[:key], as well as block-style calls such as params[:key].each { ... } or params[:key].map(&:to_s). (@​koic)
• #1627: Fix false positives in Rails/StrongParametersExpect for usages like params[:key].try(:method) and params[:key].try!(:method). (@​nicholasdower)

RuboCop Rails v2.35.1

Bug fixes

• #1616: Fix false positives in Rails/StrongParametersExpect when using nil-safe conversion methods such as to_i, to_s, to_a, to_f, and to_h on params[:key]. (@​koic)
• #1622: Fix false positives in Rails/StrongParametersExpect when using key-check methods such as key?, has_key?, include?, and member? on params[:key]. (@​koic)
• #1620: Fix false positives in Rails/StrongParametersExpect when using type-check methods such as is_a?, kind_of?, and instance_of? on params[:key]. (@​koic)

RuboCop Rails v2.35.0

Bug fixes

• #1595: Fix a false negative for Rails/I18nLocaleTexts when using redirect_back_or_to with a flash message. (@​55728)

Changes

• #1571: Add more detection patterns on Rails/ResponseParsedBody. ([@​r7kamura][])
• #1583: Extend Rails/StrongParametersExpect to detect params[:key] in method calls and raising finder methods. (@​koic)
• #1584: Add support for case statements to Rails/UnknownEnv. (@​lovro-bikic)
• #1592: Fix false negative for != comparison in Rails/UnknownEnv. (@​lovro-bikic)
