@param key<Object> The key for the param. @param value<Object> The value for the param.
@return <String> This key value pair as a param
@example normalize_param
(:name, “Bob Jones”) #=> “name=Bob%20Jones”

to_params()

@return <String> This hash as a query string
@example
{ :name => "Bob", :address => { :street => '111 Ruby Ave.', :city => 'Ruby Central', :phones => ['111-111-1111', '222-222-2222'] } }.to_params #=> "name=Bob&address[city]=Ruby Central&address[phones][]=111-111-1111&address[phones][]=222-222-2222&address[street]=111 Ruby Ave."
# File lib/nori/core_ext/hash.rb, line 18 def to_params map { |k, v| normalize_param(k,v) }.flatten.join('&') end
to_xml_attributes()
click to toggle source
@return <String> The hash as attributes for an XML tag.
@example
{ :one => 1, "two"=>"TWO" }.to_xml_attributes #=> 'one="1" two="TWO"'
# File lib/nori/core_ext/hash.rb, line 43 def to_xml_attributes map do |k, v| %{#{k.to_s.snakecase.sub(/^(.{1,1})/) { |m| m.downcase }}="#{v}"} end.join(' ') end
