ActionController::Parameters#to_param

Returns a string representation of the receiver suitable for use as a URL
query string:

  params = ActionController::Parameters.new({
    name: "David",
    nationality: "Danish"
  })
  params.to_query
  # => "name=David&nationality=Danish"

An optional namespace can be passed to enclose key names:

  params = ActionController::Parameters.new({
    name: "David",
    nationality: "Danish"
  })
  params.to_query("user")
  # => "user%5Bname%5D=David&user%5Bnationality%5D=Danish"

The string pairs "key=value" that conform the query string
are sorted lexicographically in ascending order.

This method is also aliased as +to_param+.
