On Mobile App Action( mobileInfo : Object ) -> result : Object

Paramètres	Type		Description
mobileInfo	Object	<-	Information passée par l'application mobile
result	Object	<-	Statut de l'action & synchronisation des données

Description

The On Mobile App Action 4D database method is in charge of managing actions requested by the mobile application for a specific session.

note

The mobile application must have been authenticated by the On Mobile App Authentication database method.

This database method is called by 4D when a mobile application sends an action request.

The database method receives required information from the mobile application in the mobileInfo parameter (object), and must return the action status in the result parameter (object). You must declare and initialize these parameters as follows:

 //On Mobile App Action database method
#DECLARE ($mobileInfo : Object) -> $result : Object
  // ...Code for the method
$result:=New object() //do not forget to create the object to return

The following properties are received in the mobileInfo object parameter:

Nom de propriété		Type	Description
action		Text	Action name
	id	Text	UUID de l'objet Session sur le serveur 4D
	ip	Text	Session IP
parameters		Object	Action parameters sent from the mobile application
context		Object	Context parameters for the requested action
	dataClass	Text	4D dataclass name
	entity.primaryKey	Text, Longint	(optional, returned if the action is related to a selected entity). Primary key of the entity.
	entity.relationName	Text	(optional, returned if the action is related to a linked entity). Many-to-one relation name
	parent.primaryKey	Text, Longint	(optional, returned if the action is related to a linked entity). Primary key of the parent entity.
	parent.relationName	Text	(optional, returned if the action is related to a linked entity). One-to-many relation name
	parent.dataClass	Text	(optional, returned if the action is related to a linked entity). Name of the parent 4D dataclass.

note

You can access the Session object automatically created on the 4D server from this database method. You can use this object to control the mobile session.

After processing information, the database method must return an object with the following properties in result:

Nom de propriété	Type	Description
success	Boolean	True if action has been successfully processed, False otherwise.
statusText	Text	(Optional) Message to display on the mobile application. If success=true, display message; if success=false, can be used to provide user with an explanation.
errors	Collection d'objets	(Optional) Each object contains a pair of 'parameter'/'message' keys to display in the mobile application for rejected entries.
dataSynchro	Boolean	True if the entity or table selection needs to be refreshed, false otherwise. If True, the mobile application will automatically trigger a data synchronization

Example

  // On Mobile App Action
  // 2 actions sont définies : "done" et "postponeAll"

#DECLARE ($request : Object) -> $result : Object

var $o;$context : Object

 $context:=$request.context

 Case of

    :($request.action="done")
       $o:=New object(\
       "dataClass";$context.dataClass;\
       "ID";$context.entity.primaryKey;\
       "CompletePercentage";100)

       $result:=modifyStatus($o) //appel de votre méthode projet pour modifier le statut de l'entité

    :($request.action="postponeAll")
       $o:=New object("dataClass";$context.dataClass)

       $result:=postponeAll($o) //appel de votre méthode projet pour reporter toutes les entités de la dataClass

    Else //Requête inconnue
       $result:=New object("success";False)

 End case
