New Features¶ ↑

• The convert! and convert_each! methods in the typecast_params plugin now support a :raise option for handling missing parameters specified as arguments to the methods.

  If the :raise option is set to false for convert! and the parameter argument is missing, then no conversion is done and an empty hash is returned:

  typecast_params.convert!('missing', raise: false) do |tp|
    # ...
  end
  # => {}
  

  If the :raise option is set to false for convert_each! and a :keys option is given, any key not present is ignored and nil will be returned for the converted value

  typecast_params.convert_each!(:keys=>['present', 'missing'], raise: false) do |tp|
    tp.int('b')
  end
  # => [{'b'=>1}, nil]
  

Other Improvements¶ ↑

• The :symbolize setting to the convert! and convert_each! methods in the typecast_params plugin is no longer persisted beyond the call to the method. This fixes unexpected behavior if you do:

  typecast_params.convert!(:symbolize=>true) do |tp|
    # ...
  end
  typecast_params.convert! do |tp|
    # ...
  end
