And then execute:
Or install it yourself as:
$ gem install process_chain
class UpdateUserProcess include ProcessChain def assignee_attributes(attrs) if_success do return_success user: results.user.assigne_attributes(attrs) end end def validate_user if_success do if results.user.valid? return_fail errors: results.user.errors, user: results.user else return_success end end end def save_user user = results.user if_success do if user.save return_success user: user else return_fail user: results.user end end end end ## Controller def create process = UpdateUserProcess.new(input: user) .assignee_attributes(permitted_params) .validate_user .save_user if process.success? render status: :ok, json: process.results.user else render status: :bad_request, json: process.results.errors end end
