Class Method Detail

def self.flatten_params(object : Hash, parent_key : String | Nil = nil) : Array(Tuple(String, Crest::ParamsValue)) #

Transform deeply nested params containers into a flat array of {key, value}.

parent_key — Should not be passed (used for recursion)

Crest::NestedParamsEncoder.flatten_params({:key1 => {:key2 => "123"}})
# => [{"key1[key2]", "123"}]

Instance Method Detail

def encode(params : Hash) : String #

Converts the given params into a URI query string. Keys and values will converted to strings and appropriately escaped for the URI.

Crest::NestedParamsEncoder.encode({"a" => ["one", "two", "three"], "b" => true, "c" => "C", "d" => 1})
# => 'a=one&a=two&a=three&b=true&c=C&d=1'
