Method Overview

Return Type	Summary	Class
Promise<ServiceEditsResult []>	Applies edits to features in the feature service layers.	FeatureService
Promise<ServiceContents>	Triggers the loading of the feature service instance and fetches all layers and tables.	FeatureService
Promise	Triggers the loading of the feature service instance.	FeatureService

Method Details

applyEdits Method applyEdits(edits, options){Promise<ServiceEditsResult[]>}

Applies edits to features in the feature service layers. New features can be created and existing features can be updated or deleted. Feature geometries and/or attributes may be modified. Only applicable to layers in a feature service.

When calling the applyEdits method on a service that does not have vertical coordinate system information, the z-values of the geometries in the edits object will automatically be converted to match the spatial reference of the layer. Example: The service has a horizontal spatial reference with feet units, and applyEdits() is called with z-values based on meter units, then the method will automatically convert the z values from meter to feet units. applyEdits() will pass in a sessionId during an active edit session.

Parameters

Specification

edits Object []

Object containing features and attachments to be added, updated or deleted.

Specification

id Number

Specifies the layer id of the layer that needs to be edited.

identifierFields Object

Specification

globalIdField String

optional

Specifies the globalIdField of the layer being editied.

objectIdField String

Specifies the objectIdField of the layer being edited.

addFeatures Graphic []|Collection<Graphic>

optional

An array or a collection of features to be added. Values of non nullable fields must be provided when adding new features. Date fields must have numeric values representing universal time.

updateFeatures Graphic []|Collection<Graphic>

optional

An array or a collection of features to be updated. Each feature must have valid objectId. Values of non nullable fields must be provided when updating features. Date fields must have numeric values representing universal time.

deleteFeatures Graphic []|Collection<Graphic>|Object []

optional

An array or a collection of features, or an array of objects with objectId or globalId of each feature to be deleted. When an array or collection of features is passed, each feature must have a valid objectId. When an array of objects is used, each object must have a valid value set for objectId or globalId property.

addAttachments AttachmentEdit []

optional

An array of attachments to be added. Applies only when the options.globalIdUsed parameter is set to true. User must provide globalIds for all attachments to be added.

updateAttachments AttachmentEdit []

optional

An array of attachments to be updated. Applies only when the options.globalIdUsed parameter is set to true. User must provide globalIds for all attachments to be updated.

deleteAttachments String []

optional

An array of globalIds for attachments to be deleted. Applies only when the options.globalIdUsed parameter is set to true.

options Object

optional

Additional edit options to specify when editing features or attachments.

Specification

gdbVersion String

optional

The geodatabase version to apply the edits. This parameter applies only if the capabilities.data.isVersioned property of the layer is true.

globalIdUsed Boolean

optional

Indicates whether the edits can be applied using globalIds of features or attachments. This parameter applies only if the layer's capabilities.editing.supportsGlobalId property is true. When false, globalIds submitted with the features are ignored and the service assigns new globalIds to the new features. When true, the globalIds must be submitted with the new features. When updating existing features, if the globalIdUsed is false, the objectIds of the features to be updated must be provided. If the globalIdUsed is true, globalIds of features to be updated must be provided. When deleting existing features, set this property to false as deletes operation only accepts objectIds at the current version of the API.

When adding, updating or deleting attachments, globalIdUsed parameter must be set to true and the attachment globalId must be set. For new attachments, the user must provide globalIds. In order for an attachment to be updated or deleted, clients must include its globalId. Attachments are not supported in an edit payload when globalIdUsed is false.

honorSequenceOfEdits Boolean

optional

Added at 10.5 and works with ArcGIS Server services only. This parameter specifies whether to apply edits in the order they are submitted in the JSON. If true, edits will apply in the submitted order. If false, which is the default, edits will apply in ascending layer-ID order. All the edits for the layer with the lowest ID will apply first.

usePreviousEditMoment Boolean

optional

This option was added at 10.6. This is set by a client during long transaction editing on a branch version. This parameter is used to apply the edits with the same edit moment as the previous set of edits. This allows an editor to apply a single block of edits partially, complete another task, and then complete the block of edits. When set to true, the edits are applied with the same edit moment as the previous sets of edits. When set to false the edits are applied with a new edit moment. By default, this parameter is set to false.

Returns

Type	Description
Promise<ServiceEditsResult []>	Results returned from the applyEdits method. It contains features that were added, deleted or updated in different feature layers. It also contains the edit moment.
