Models

Models on the client represent server records. In Mobile Sync, model objects are instances of Force.SObject, a subclass of the Backbone.Model class. SObject extends Model to work with Salesforce APIs and, optionally, with SmartStore.

You can perform the following CRUD operations on SObject model objects:

• Create
• Destroy
• Fetch
• Save
• Get/set attributes

In addition, model objects are observable: Views and controllers can receive notifications when the objects change.

Force.SObject adds the following properties to Backbone.Model:

sobjectType

Required. The name of the Salesforce object that this model represents. This value can refer to either a standard object or a custom object.

fieldlist

Required. Names of fields to fetch, save, or destroy.

cacheMode

Offline behavior.

mergeMode

Conflict handling behavior.

cache

For updatable offline storage of records. The Mobile Sync comes bundled with Force.StoreCache, a cache implementation that is backed by SmartStore.

cacheForOriginals

Contains original copies of records fetched from server to support conflict detection.

You can assign values for model properties in several ways:

• As properties on a Force.SObject instance.
• As methods on a Force.SObject sub-class. These methods take a parameter that specifies the desired CRUD action (“create”, “read”, “update”, or “delete”).
• In the options parameter of the fetch(), save(), or destroy() function call.

For example, these code snippets are equivalent.
