  tagging_contexts.each {|context| set_tag_list_on(context, '') }
end

#has_tags? ⇒ Boolean

It should be noted that our usage of tag contexts is apparently incongruent with acts_as_taggable_on’s intentions. It goes to lengths to write class methods for each context with the apparent intention that these be used separately, whereas we needed contexts to be more dynamic (all contexts but “tags” are user defined).

The gem provides custom contexts but they’re not very well supported and somewhat broken (see #tagging_contexts below).

Because of the way AATO expects contexts to be used, it makes some assumptions, and writes a bunch of helper methods to the class for each. These are useless to us really and only serve to add some confusion to the scope. E.g. for acts_as_taggable_on :tags (the default), the following methods are created:

tag_taggings (has_many) tags (has_many) tags_list tags_list= all_tags_list

It’s important to note that these methods all only deal with the “tags” context and won’t return any tag which does not have it.

The actual associations on the taggable record are “taggings” and “base_tags”, which ignores context, returning all tags.

Returns:

  • (Boolean)
