component_locals(locals) click to toggle source

because rails does some weird stuff to make it easy to access the locals in templates, this strips out any problem-causing key names (e.g. “class”), but gives you a new local, “prop” that has access to all the locals that were passed in (including the stripped out ones)

references:

# File lib/rails_components.rb, line 42
def component_locals(locals)
  locals ||= {}
  locals.extend(HtmlHelpers)
  locals.except(*COMPONENT_RESERVED_WORDS).merge(props: locals)
end
