Methods
(static) _clearAllState()
Static methods
(static) createWithoutData(id) → {Parse.Object}
Creates a reference to a subclass of Parse.Object with the given id. This does not exist on Parse.Object, only on subclasses.
A shortcut for:
var Foo = Parse.Object.extend("Foo"); var pointerToFoo = new Foo(); pointerToFoo.id = "myObjectId";
Parameters:
Name | Type | Description |
---|---|---|
id |
String
|
The ID of the object to create a reference to. |
(static) destroyAll(list, options) → {Parse.Promise}
Destroy the given list of models on the server if it was already persisted.
Unlike saveAll, if an error occurs while deleting an individual model, this method will continue trying to delete the rest of the models if possible, except in the case of a fatal error like a connection error.
In particular, the Parse.Error object returned in the case of error may be one of two types:
- A Parse.Error.AGGREGATE_ERROR. This object's "errors" property is an array of other Parse.Error objects. Each error object in this array has an "object" property that references the object that could not be deleted (for instance, because that object could not be found).
- A non-aggregate Parse.Error. This indicates a serious error that caused the delete operation to be aborted partway through (for instance, a connection failure in the middle of the delete).
Parse.Object.destroyAll([object1, object2, ...], { success: function() { // All the objects were deleted. }, error: function(error) { // An error occurred while deleting one or more of the objects. // If this is an aggregate error, then we can inspect each error // object individually to determine the reason why a particular // object was not deleted. if (error.code === Parse.Error.AGGREGATE_ERROR) { for (var i = 0; i < error.errors.length; i++) { console.log("Couldn't delete " + error.errors[i].object.id + "due to " + error.errors[i].message); } } else { console.log("Delete aborted because of " + error.message); } }, });
Parameters:
Name | Type | Description |
---|---|---|
list |
Array
|
A list of |
options |
Object
|
A Backbone-style callback object. |
(static) disableSingleInstance()
Disable single instance objects, where any local objects with the same Id share the same attributes, and stay synchronized with each other. When disabled, you can have two instances of the same object in memory without them sharing attributes.
(static) enableSingleInstance()
Enable single instance objects, where any local objects with the same Id share the same attributes, and stay synchronized with each other. This is disabled by default in server environments, since it can lead to security issues.
(static) extend(className, protoProps, classProps) → {Class}
Creates a new subclass of Parse.Object for the given Parse class name.
Every extension of a Parse class will inherit from the most recent previous extension of that class. When a Parse.Object is automatically created by parsing JSON, it will use the most recent extension of that class.
You should call either:
var MyClass = Parse.Object.extend("MyClass", { Instance methods, initialize: function(attrs, options) { this.someInstanceProperty = [], Other instance properties } }, { Class properties });or, for Backbone compatibility:
var MyClass = Parse.Object.extend({ className: "MyClass", Instance methods, initialize: function(attrs, options) { this.someInstanceProperty = [], Other instance properties } }, { Class properties });
Parameters:
Name | Type | Description |
---|---|---|
className |
String
|
The name of the Parse class backing this model. |
protoProps |
Object
|
Instance properties to add to instances of the class returned from this method. |
classProps |
Object
|
Class properties to add the class returned from this method. |
Returns:
- Type:
-
Class
A new subclass of Parse.Object.
(static) fetchAll(list, options)
Fetches the given list of Parse.Object. If any error is encountered, stops and calls the error handler.
Parse.Object.fetchAll([object1, object2, ...], { success: function(list) { // All the objects were fetched. }, error: function(error) { // An error occurred while fetching one of the objects. }, });
Parameters:
Name | Type | Description |
---|---|---|
list |
Array
|
A list of |
options |
Object
|
A Backbone-style callback object. |
(static) fetchAllIfNeeded(list, options)
Fetches the given list of Parse.Object if needed. If any error is encountered, stops and calls the error handler.
Parse.Object.fetchAllIfNeeded([object1, ...], { success: function(list) { // Objects were fetched and updated. }, error: function(error) { // An error occurred while fetching one of the objects. }, });
