module Decidim
module Core
# An abstract class with the logic for the GraphQL endpoint for a single component to be searchable.
# Normal components (such as Proposal) can inherit from this class and just
# add the needed search arguments
#
# Usually something like:
#
# class ProposalFinderHelper < Decidim::Core::ComponentFinderBase
# argument :id, !types.ID, "The ID of the proposal"
# end
#
# For an example check
# decidim-proposals/app/types/decidim/proposals/proposals_type.rb

end

@query = { component: component }
args.keys.each do |key|
@query[key] = args[key]
end

end
# By default, any model in its defaul scope
# Particular implementations may restrict this by adding
# additional constrains
