module Decidim
# A helper to allow only Decidim params to be added to a link.
# This is useful when we want to preserve the params from a search, ordering
# or paginating results. Using this, we can link back to where the user was
# at the show page.
module FilterParamsHelper
# Public: Builds a hash to be added to a _path or _url method with only
# allowed params.
#
# params - An optional Hash with the values of the params. It will try to
# get them from the controller if none are present.
#
# Returns a Hash.
