.build(keys, values, present) ⇒ Hash

the nested params for the pairs.

Examples:

ActionDispatch::ParamBuilder.build(["a[]"], ["1"], [true])   # => { "a" => ["1"] }

Parameters:

  • keys (Array<String>) —

    the decoded parameter names

  • values (Array<String>) —

    the decoded values ("" where the pair carried none)

  • present (Array<Boolean>) —

    which pairs carried a value

Returns:

  • (Hash) —

    the nested params; nil where the input is a 400

    store(params, keys[i], v, 0)
    i += 1
  end
  params
rescue ParamBuilder::Invalid
  nil
end

.from_query_string(s) ⇒ Hash

a query string (or an urlencoded body) straight to the nested params.

Examples:

ActionDispatch::ParamBuilder.from_query_string("a[b]=1")   # => { "a" => { "b" => "1" } }

Parameters:

  • s (String) —

    the raw query string

Returns:

  • (Hash) —

    the nested params; nil where the input is a 400
