Missing top-level class documentation comment. Open
class OrganizersAndModeratorsQuery
- Read upRead up
- Exclude checks
This cop checks for missing top-level documentation of classes and modules. Classes with no body are exempt from the check and so are namespace modules - modules that have nothing in their bodies except classes, other modules, or constant definitions.
The documentation requirement is annulled if the class or module has a "#:nodoc:" comment next to it. Likewise, "#:nodoc: all" does the same for all its children.
Example:
# bad
class Person
# ...
end
# good
# Description/Explanation of Person class

Use %i
or %I
for an array of symbols. Open
[:title, :date, :group_id]
- 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]
Redundant self
detected. Open
random_offset = rand(1..self.count - groups_number)
- Read upRead up
- Exclude checks
This cop checks for redundant uses of self
.
The usage of self
is only needed when:
Sending a message to same object with zero arguments in presence of a method name clash with an argument or a local variable.
Calling an attribute writer to prevent an local variable assignment.
Note, with using explicit self you can only send messages with public or protected scope, you cannot send private messages this way.
Note we allow uses of self
with operators because it would be awkward
otherwise.
Example:
# bad
def foo(bar)
self.baz
end
# good
def foo(bar)
self.bar # Resolves name clash with the argument.
end
def foo
bar = 1
self.bar # Resolves name clash with the local variable.
end
def foo
%w[x y z].select do |bar|
self.bar == bar # Resolves name clash with argument of the block.
end
end

Align the elements of a hash literal if they span more than one line. Open
message: "is already a member of the group"
- Read upRead up
- Exclude checks
Check that the keys, separators, and values of a multi-line hash literal are aligned according to configuration. The configuration options are:
- key (left align keys)
- separator (align hash rockets and colons, right align keys)
- table (left align keys, hash rockets, and values)
The treatment of hashes passed as the last argument to a method call can also be configured. The options are:
- always_inspect
- always_ignore
- ignore_implicit (without curly braces)
- ignore_explicit (with curly braces)
Example:
# EnforcedHashRocketStyle: key (default)
# EnforcedColonStyle: key (default)
# good
{
foo: bar,
ba: baz
}
{
:foo => bar,
:ba => baz
}
# bad
{
foo: bar,
ba: baz
}
{
:foo => bar,
:ba => baz
}
Example:
# EnforcedHashRocketStyle: separator
# EnforcedColonStyle: separator
#good
{
foo: bar,
ba: baz
}
{
:foo => bar,
:ba => baz
}
#bad
{
foo: bar,
ba: baz
}
{
:foo => bar,
:ba => baz
}
{
:foo => bar,
:ba => baz
}
Example:
# EnforcedHashRocketStyle: table
# EnforcedColonStyle: table
#good
{
foo: bar,
ba: baz
}
{
:foo => bar,
:ba => baz
}
#bad
{
foo: bar,
ba: baz
}
