REST API Returns a JSON Response/services/data/v28.0/query/?q=SELECT Id, Name FROM Opportunity

Some things you can do with your soup…• Register a Soup with an IndexSpec• Query a Soup using a QuerySpec• Upsert Data to a Soup

• Delete Data from a Soup

• Remove a Soup

IndexSpec• JSON Object

• Fields to index

• “string” or “integer”[

{"path":"Id","type":"string"},

{"path":"Name","type":"string"}

]

QuerySpec

buildAllQuerySpec(path,order,pageSize)Query all records from the object in the given sort order (or null order)

buildExactQuerySpec(path,matchKey,pageSize)Search for records with index path values matching the key.

buildRangeQuerySpec(path,beginKey,endKey,pageSize)Return all records with an index path value between the two range values

buildLikeQuerySpec(path,likeKey,order,pageSize)Basically “select * from [table] LIKE ‘%[likeKey]%’”

buildSmartQuerySpec(smartSql,pageSize)Basically “select * from [table] LIKE ‘%[likeKey]%’”

SmartSQLSELECT {departments:name}, {employees:lastName}

FROM {employees}, {departments}

WHERE {departments:deptCode} = {employees:deptCode}

ORDER by {departments:name}, {employees:lastName}

SmartSync• Extends Backbone.js

• Can be used with or without a SmartStore Cache

• Queries returned as Backbone Model Collections

Backbone• MV* Framework

• Models: Individual records• Collections: Collections of Model records

• View: Javascript backing for the stuff that you see

• Router: routes everything after the # in a URL to application functions• http://myapp.com/#/user/list

Force.SObject• sobjectType: Account, Opportunity, etc.

• fieldlist: ["Id", "Name", "Amount", "StageName"]

• cacheMode: client, server write order

• mergeMode: how to handle conflicts

• cache: if using SmartStore

• cacheForOriginals: backup data for conflict detection

Force.SObjectCollection• config: determines queries used to access data

• cache: if using SmartStore

• cacheForOriginals: backup data for conflict detection

Force.StoreCache• soupName: Name of the SmartStore Soup

• additionalIndexSpecs: IndexSpecs to use, in addition to defaults

• keyField: Name of the field containing the record Id

• __locally_created__• __locally_updated__• __locally_deleted__• __local__ (set to true if any of the previous three are true)
