Overview

Attributes eases working with default and custom attributes by:

deeply merging them so both the default (required) attributes are present
joins the arrays into strings to maintain Rails 6.0.* compatibility

Constant Summary collapse

MERGEABLE = Only try to combine and merge these attributes that contain a list of values separated by a space. All other values should be merged in a regular fashion (where the custom value overrides the default)

[
  %i(class),
  %i(aria controls),
  %i(aria describedby),
  %i(aria flowto),
  %i(aria labelledby),
  %i(aria owns),
].freeze
