helpers. A minimal implementation could be: class Person # Required dependency for ActiveModel::Errors extend ActiveModel::Naming def initialize @errors = ActiveModel::Errors.new(self) end attr_accessor :name attr_reader :errors def validate! errors.add(:name, :blank, message: "cannot be nil") windows error message sound if name.nil? end # The following methods are needed to be minimally implemented error message generator text def read_attribute_for_validation(attr) send(attr) end def self.human_attribute_name(attr, options = {}) attr end def self.lookup_ancestors [self] end end The last three error message generator mac methods are required in your object for Errors to be able to generate error messages correctly and also handle multiple languages. Of course, if you extend your object with ActiveModel::Translation you will http://php.net/manual/en/function.trigger-error.php not need to implement the last two. Likewise, using ActiveModel::Validations will handle the validation related methods for you. The above allows you to do: person = Person.new person.validate! # => ["cannot be nil"] person.errors.full_messages # => ["name cannot be nil"] # etc..

I want to the know the difference of usage between Generate Error activity and https://community.tibco.com/questions/whats-difference-between-using-generate-error-activity-and-catch-activity catch activity Oct 23, 2015 - 3:39pmmuthu121521 Flag as Inappropriate + Add a Comment (2) Answers 0 reset Hi Muthu, Generate Error Activity : It is mainly used to implement user defined exception. Lets discuss one simple scenario https://www.drupal.org/project/generate_errors to understand the usage of this activity. Assume we have to implement a rule where we should only allow a person of age <= 60 (Age is Integer type variable). Now we have to generate error when receive age field error message as 60+. I am passing 61 in the input and system should not allow this value to process. But, In normal execution system accept this value because 61 is a valid Integer. Here comes the concept of user defined exception. We will make one condition where we check that if age > 60 then we have to raise one error/exception. To achieve this we can use Generate Error Activity. Here we can add suitable messages for the source I.e. error message generator Invalid age or age should be less/equal to 60. On the other-hand Catch Activity is used to handle error/exception at the runtime. The error in the above example can be handled by using Catch activity. Here we can add the suitable process flow, which inform sender/source about violation of rule(Invalid Data : Age > 60).

Any errors in Subprocess with a) Alone Catch will not be propgated to Main process. b) With Catch and Generate, error will be propgated to Main process. Thanks Lokesh Sarma.

"Do I know exactly how my server will respond in error conditions?" "I haven't seen a E_STRICT error, I wonder what that looks like?" Wonder no longer. Generate Errors is a module that provides an user interface for developer to manually generate errors. A developer can intentionally: Select or manually specify HTTP status code in the response header and optionally exit Throw an uncaught PHP Exception Exhaust memory in an infinite loop Trigger a PHP error level, including E_ERROR, E_WARNING, E_PARSE, E_NOTICE, E_USER_ERROR, E_USER_WARNING, E_USER_NOTICE, E_STRICT, and E_RECOVERABLE_ERROR Benchmark PHP execution in error conditions The selected error will occur only once, allowing a developer or systems administrator to test system behaviors, such as custom error messages from the server and so forth. A status message will be shown describing the generated error, and a log message will be recorded in watchdog prior to the triggered error to document who did what and when. This module should not be deployed in any public-facing environment and is intended for development and testing purposes only.Supporting organizations: Four KitchensCurrent Development PantheonInitial Development Project InformationMaintenance status: Actively maintainedDevelopment status: Under active developmentModule categories: Developer, UtilityReported installs: 5 sites currently report using this module.
