How to handle those cases when you just can't deal with how Rails Hash.to_query uses '+' instead of '%20'

spacey_hash.rb

#  Add this to initializers
#
#   { foo: 'real foo' }.to_query  =>  real+foo
#   { foo: 'real foo' }.to_spacey_query =>  real%20foo

Hash.class_eval do
  def to_spacey_query
    collect do |key, value|
      "#{ key.to_param }=#{ ERB::Util::u(value.to_param.to_s)} "
    end.sort * '&'
  end
end
