Class: Notification

TrellinatorCore.Notification(notification)

The Notification object takes a notification from the Trello API sent to a webhook and makes it easy to determine what type of event took place and to get access to the entities that were part of the notification. The notifications passed into this constructor are always sent to webhooks registered at the board level. There are 4 types of method:

  • methods that return an object that was the source or origination of this notification, throwing an exception if that object is not present which indicates in turn that type of notification did not occur. The first part of the function name is the verb, with the object coming after, eg. archivedCard or completedChecklistItem.

  • methods that return an entity that was part of the notification, such as board(), card() and member(). Given these notifications are always at the board level, there is always a board() and given every notification originates with an action by a member there is always a member() however there is not always a card(), so if for example this notification is a list name being updated the card() method will throw an InvalidActionException

  • Finally there are a couple of convenience functions that are just shorthand for a few different common scenarios such as actionOnDueDate and replyToMember

  • Static methods that are used globally and are simply grouped within this class for logical reasons

There are some methods that are deprecated or used internally by other class methods so you can ignore those, they are marked as such in the code comments, but aren't included in the API documentation.

Even though all methods are marked as "static" by jsdoc, the ones that start with "this." aren't static. I don't know how to make jsdoc display them as non-static, so if you do then please send a pull request :)

Methods that deal with detecting whether an action took place will throw an InvalidActionException if that action did not take place.

Unless you want to explicitly take action in the case that some action didn't occur, you don't need to catch these exceptions; Trellinator will catch them for you. An InvalidActionException is not considered "fatal", neither is an InvalidDataException (typically thrown by entity classes or the IterableCollection).

If you do want to catch exceptions, you should look at the Exceptions.js documentation and the two static methods on this class Notification.logException and Notification.expectException to see how to do this according to Trellinator best practices

Constructor

new Notification(notification)

Parameters:
Name Type Description
notification Object

an object that has been posted to a webhook from the Trello API

Source:

Methods

(static) Notification.expectException(type, e)

When you catch an exception, throw it again if it is not the type you expected. This is useful when catching exceptions thrown by entity classes such as Card and Board. These will throw InvalidDataExceptions but will never intentionally throw a ReferenceError for example.

Parameters:
Name Type Description
type function

the constructor function of an exception, typically one from Exceptions.js

e Object

the exception you caught

Source:
Example
var notif = new Notification(posted);
//Remove any labels that were added that
//aren't "Urgent"
try
{
    var label = notif.addedLabel("Urgent");
}

catch(e)
{
    Notification.expectException(InvalidDataException,e);
    notif.card().removeLabel(notif.addedLabel());
}

(static) Notification.logException(message, e)

Log a message in the Info Log tab if this is a non fatal exception, or what is considered an "Expected Exception" from the types in Exceptions.js. These are exceptions thrown by the Notification class and entity classes like Card and Board. This static method will write any message from an "expected" exception to Info Log and rethrow the exception if it isn't one of these types. This method is used by Trellinator when executing functions anyway so you don't need to wrap all your functions using this try/catch, however it can be useful to have a shorthand way of creating a log entry for expected exceptions and then taking some other action, but halting execution if the exception was not expected

Parameters:
Name Type Description
message string

prepend the exception message

e Object

the exception that was caught

Source:
Example
var notif = new Notification(posted);

try
{
    notif.card().postComment("Hi there!");
}

catch(e)
{
    Notification.logException("We didn't see a card",e);
}

(static) this.actionOnDueDate(function_name, signature, callback)

Schedule a function to be executed by the Execution Queue at some point relative to the due date on a card, even if the due date was not added as part of the notification.

It is therefore important to use this in conjunction with another notification type because otherwise any notification for a card with a due date will schedule the function to execute.

By default, will execute on the due date, but you can optionally pass in a callback to modify the date relative to the due date of the card.

Parameters:
Name Type Description
function_name string

the name of the function to execute

signature string

an arbitrary string but usually just the signature passed into the original function

callback function

(optional) a function into which the due date as a Date object, and a second argument with the notification params that will be passed into the function

Source:
Example
try
{
    var notif = new Notification(posted);
    notif.createdCard();
    //Action 3 days after the due date on a card only
    //if the card was just created
    notif.actionOnDueDate("doSomething",signature,function(date,params)
    {
        date.addDays(3).at("9:00");
        params.arbitrary_string = "I ain't afraid of no ghost";
    });
}

(static) this.actionOnDueDateAdded(function_name, signature, callback)

Schedule a function to be executed by the Execution Queue at some point relative to the due date added to or edited on a card.

By default, will execute on the due date, but you can optionally pass in a callback to modify the date relative to the due date of the card.

Parameters:
Name Type Description
function_name string

the name of the function to execute

signature string

an arbitrary string but usually just the signature passed into the original function

callback function

(optional) a function into which the due date as a Date object, and a second argument with the notification params that will be passed into the function

Source:
Example
new Notification(posted).actionOnDueDateAdded("doSomething",signature,function(date,params)
{
    date.addDays(3).at("9:00");
    params.arbitrary_string = "I ain't afraid of no ghost";
});

(static) this.addedCard(optionaly)

Return a Card object if a card was added to a list as part of this notification.

If none of these things happened throws an InvalidActionException
