Open

      super || object.kind_of?(klass)
Severity: Minor

var.is_a?(Date)
var.is_a?(Integer)

module Draper
Severity: Minor
Found in lib/draper/compatibility/global_id.rb by rubocop

This cop is designed to help upgrade to Ruby 3.0. It will add the comment # frozen_string_literal: true to the top of files to enable frozen string literals. Frozen string literals may be default in Ruby 3.0. The comment will be added below a shebang and encoding comment. The frozen string literal comment is only valid in Ruby 2.3+.

Example: EnforcedStyle: when_needed (default)

# The `when_needed` style will add the frozen string literal comment
# to files only when the `TargetRubyVersion` is set to 2.3+.
# bad
module Foo
  # ...
end

# good
# frozen_string_literal: true

module Foo
  # ...
end

Example: EnforcedStyle: always

# The `always` style will always add the frozen string literal comment
# to a file, regardless of the Ruby version or if `freeze` or `<<` are
# called on a string literal.
# bad
module Bar
  # ...
end

# good
# frozen_string_literal: true

module Bar
  # ...
end

Example: EnforcedStyle: never

# The `never` will enforce that the frozen string literal comment does
# not exist in a file.
# bad
# frozen_string_literal: true

module Baz
  # ...
end

# good
module Baz

Replace class var @@default_query_methods_strategy with a class instance var.

      @@default_query_methods_strategy = strategy
Severity: Minor
Found in lib/draper/configuration.rb by rubocop

This cop checks for uses of class variables. Offenses are signaled only on assignment to class variables to reduce the number of offenses that would be reported.

Use Hash#key? instead of Hash#has_key?.
Open

        @context = object.context unless options.has_key?(:context)
Severity: Minor
Found in lib/draper/decorator.rb by rubocop

This cop (by default) checks for uses of methods Hash#haskey? and Hash#hasvalue? where it enforces Hash#key? and Hash#value? It is configurable to enforce the inverse, using verbose method names also.

Example: EnforcedStyle: short (default)

# bad Hash#haskey? Hash#hasvalue?

# good Hash#key? Hash#value?

Example: EnforcedStyle: verbose

# bad Hash#key? Hash#value?

# good Hash#haskey? Hash#hasvalue?

Severity: Minor
Found in lib/draper/query_methods.rb by rubocop

This cop checks for the presence of method_missing without also defining respond_to_missing? and falling back on super.

Example:

rspec_guard spec_paths: 'spec/integration', env: {'RAILS_ENV' => 'production'} do
Severity: Minor
Found in Guardfile by rubocop

Checks that braces used for hash literals have or don't have surrounding space depending on configuration.

Example: EnforcedStyle: space

# The `space` style enforces that hash literals have
# surrounding space.

# bad
h = {a: 1, b: 2}

# good
h = { a: 1, b: 2 }

Example: EnforcedStyle: no_space

# The `no_space` style enforces that hash literals have
# no surrounding space.

# bad
h = { a: 1, b: 2 }

# good
h = {a: 1, b: 2}

Example: EnforcedStyle: compact

# The `compact` style normally requires a space inside
# hash braces, with the exception that successive left
# braces or right braces are collapsed together in nested hashes.

# bad
h = { a: { b: 2 } }

# good
h = { a: { b: 2 }}

%w-literals should be delimited by [ and ].
Open

rspec_guard spec_paths: %w{spec/draper spec/generators} do
Severity: Minor
Found in Guardfile by rubocop

This cop enforces the consistent usage of %-literal delimiters.

Specify the 'default' key to set all preferred delimiters at once. You can continue to specify individual preferred delimiters to override the default.

Example:

# Style/PercentLiteralDelimiters:
#   PreferredDelimiters:
#     default: '[]'
#     '%i':    '()'

# good
%w[alpha beta] + %i(gamma delta)

# bad
%W(alpha #{beta})

# bad
%I(alpha beta)
