Use %i
or %I
for an array of symbols. Open
before_action :check_user, only: [:show, :edit, :update, :destroy]
- Read upRead up
- Exclude checks
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 of
3` 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]
Put empty method definitions on a single line. Open

- Read upRead up
- Exclude checks
This cop checks for the formatting of empty method definitions.
By default it enforces empty method definitions to go on a single
line (compact style), but it can be configured to enforce the end
to go on its own line (expanded style).
Note: A method definition is not considered empty if it contains comments.
Example: EnforcedStyle: compact (default)
# bad
def foo(bar)
end
def self.foo(bar)
end
# good
def foo(bar); end
def foo(bar)
# baz
end
def self.foo(bar); end
Example: EnforcedStyle: expanded
# bad
def foo(bar); end
def self.foo(bar); end
# good
def foo(bar)
end

Omit parentheses for ternary conditions. Open
(eql && sort_asc) ? 'desc' : 'asc'
- Read upRead up
- Exclude checks
This cop checks for the presence of parentheses around ternary
conditions. It is configurable to enforce inclusion or omission of
parentheses using EnforcedStyle
. Omission is only enforced when
removing the parentheses won't cause a different behavior.
Example: EnforcedStyle: requirenoparentheses (default)
# bad
foo = (bar?) ? a : b
foo = (bar.baz?) ? a : b
foo = (bar && baz) ? a : b
# good
foo = bar? ? a : b
foo = bar.baz? ? a : b
foo = bar && baz ? a : b
Example: EnforcedStyle: require_parentheses
# bad
foo = bar? ? a : b
foo = bar.baz? ? a : b
foo = bar && baz ? a : b
# good
foo = (bar?) ? a : b
foo = (bar.baz?) ? a : b
foo = (bar && baz) ? a : b
Example: EnforcedStyle: requireparentheseswhen_complex
# bad
foo = (bar?) ? a : b
foo = (bar.baz?) ? a : b
foo = bar && baz ? a : b
# good
foo = bar? ? a : b
