  end
end

#search_related_to ⇒ Object

Filters Proposals by the name of the classes they are linked to. By default, returns all Proposals. When a ‘related_to` param is given, then it camelcases item to find the real class name and checks the links for the Proposals.

The ‘related_to` param is expected to be in this form:

"decidim/meetings/meeting"

This can be achieved by performing ‘klass.name.underscore`.

Returns only those proposals that are linked to the given class name.
