Use safe navigation (&.) instead of try!.
Open

    @ongoing_match ||= Table.default.try!(:ongoing_match)
Severity: Minor
Found in app/controllers/application_controller.rb by rubocop

This cop converts usages of try! to &.. It can also be configured to convert try. It will convert code to use safe navigation if the target Ruby version is set to 2.3+

Example:

# ConvertTry: false
  # bad
  foo.try!(:bar)
  foo.try!(:bar, baz)
  foo.try!(:bar) { |e| e.baz }

  foo.try!(:[], 0)

  # good
  foo.try(:bar)
  foo.try(:bar, baz)
  foo.try(:bar) { |e| e.baz }

  foo&.bar
  foo&.bar(baz)
  foo&.bar { |e| e.baz }


# ConvertTry: true
  # bad
  foo.try!(:bar)
  foo.try!(:bar, baz)
  foo.try!(:bar) { |e| e.baz }
  foo.try(:bar)
  foo.try(:bar, baz)
  foo.try(:bar) { |e| e.baz }

  # good
  foo&.bar
  foo&.bar(baz)
  foo&.bar { |e| e.baz }

Use %i or %I for an array of symbols.

This cop can check for array literals made up of symbols that are not using the %i() syntax.

Alternatively, it checks for symbol arrays using the %i() syntax on projects which do not want to use that syntax.

Configuration option: MinSize If set, arrays with fewer elements than this value will not trigger the cop. For example, a MinSize of3` will not enforce a style on an array of 2 or fewer elements.

Example: EnforcedStyle: percent (default)

# good
%i[foo bar baz]

# bad
[:foo, :bar, :baz]

Example: EnforcedStyle: brackets

# good
[:foo, :bar, :baz]

# bad
%i[foo bar baz]
