def tag_cloud(tags, classes)
  return if tags.empty?
  max_count = tags.sort_by(&:count).last.count.to_f
  tags.each do |tag|
    index = ((tag.count / max_count) * (classes.size - 1)).round
    yield tag, classes[index]
  end
end

#tag_cloud_links(tags, key, options = {}) ⇒ Object

Renders span.tag_list from an array of tag objects (respond to .name and .count). Resolves URL via ‘key_tag_url(name)` in the current view context.

tag_cloud_links(contact.available_tags, :contact)   # → contact_tag_url(name)
tag_cloud_links(tags_cloud, :people)                # → people_tag_url(name)

Raises:

  • (NoMethodError)
