Method: Addressable::URI#query_values=

Defined in:
lib/addressable/uri.rb

#query_values=(new_query_values) ⇒ Object

Sets the query component for this URI from a Hash object. An empty Hash or Array will result in an empty query string.

Examples:

uri.query_values = {:a => "a", :b => ["c", "d", "e"]}
uri.query
# => "a=a&b=c&b=d&b=e"
uri.query_values = [['a', 'a'], ['b', 'c'], ['b', 'd'], ['b', 'e']]
uri.query
# => "a=a&b=c&b=d&b=e"
uri.query_values = [['a', 'a'], ['b', ['c', 'd', 'e']]]
uri.query
# => "a=a&b=c&b=d&b=e"
uri.query_values = [['flag'], ['key', 'value']]
uri.query
# => "flag&key=value"

Parameters:

  • new_query_values (Hash, #to_hash, Array) —

    The new query values.
