module ActionController # Specify binary encoding for parameters for a given action. module ParameterEncoding extend ActiveSupport::Concern module ClassMethods def inherited(klass) # :nodoc: super klass.setup_param_encode end def setup_param_encode # :nodoc: @_parameter_encodings = {} end def binary_params_for?(action) # :nodoc: @_parameter_encodings[action.to_s] end # Specify that a given action's parameters should all be encoded as # ASCII-8BIT (it "skips" the encoding default of UTF-8). # # For example, a controller would use it like this: # # class RepositoryController < ActionController::Base # skip_parameter_encoding :show # # def show # @repo = Repository.find_by_filesystem_path params[:file_path] # # # `repo_name` is guaranteed to be UTF-8, but was ASCII-8BIT, so # # tag it as such # @repo_name = params[:repo_name].force_encoding 'UTF-8' # end # # def index # @repositories = Repository.all # end # end # # The show action in the above controller would have all parameter values # encoded as ASCII-8BIT. This is useful in the case where an application # must handle data but encoding of the data is unknown, like file system data. def skip_parameter_encoding(action) @_parameter_encodings[action.to_s] = true end end end end
