Model class

Level: intermediate

The Model class implements a data model to execute operations with data source records.

Methods

load()

Retrieves a record from a data source. A configuration object is a key-value collection.

Parameters

attributes

Specifies record columns to retrieve from the data source. The attributes property limits the retrieved data, which, in turn, improves performance and reduces unnecessary data transfer.

parameters

An array of query filters.

Parameters

type	The parameter type. The `ModelParameterType.Filter` value marks the parameter as a query filter.
value	The `BaseFilter` class instance that limits the retrieved data using the specified condition.

To retrieve a dedicated record, set the ModelParameterType.PrimaryColumnValue value to the type parameter and record ID to the value parameter.

Example that retrieves a dedicated record
const result = await model.load({
    attributes: ['Name'],
    parameters: [{
        type: ModelParameterType.PrimaryColumnValue,
        value: 'd4f93b6c-362c-4954-8bd6-1658e9206d4e'
    }]
});

loadOptions

Additional properties required to set up pagination, sorting and caching.

Parameters

pagingConfig

Sets up pagination that controls rows of data to retrieve at once.

Parameters

rowsOffset	An initial position (offset) to load the first portion of data. If you omit the property, Creatio sets the offset to "0."
rowCount	The number of records to upload to the page.

sortingConfig

Sets up sorting of retrieved data.

Parameters

columns

Specifies the initial data sorting settings.

Parameters

columnName

Name of the column by which to sort data.

direction

Sorting order.

Available values

asc	Ascending.
desc	Descending.

cacheOperation

Manages caching of data retrieved from the data source.

Parameters

updateCache

The flag that specifies whether the load() operation must retrieve data from the server and write it to the cache. By default, true.

Available values

true

Mobile Creatio retrieves data from the server and caches retrieved data. Mobile Creatio omits the updateCache: true parameter value in the following cases:

The readCacheMode parameter is set to ReadCacheMode.ForceLocal.
The Mobile application operation mode (MobileApplicationMode code) system setting is set to "offline" and the EnableMobileDataAutoSynchronization additional feature is disabled.

false

Mobile Creatio works with data directly from the cache, omitting the data source. This accelerates data retrieval. Mobile Creatio omits the updateCache: false parameter value in the following cases:

The readCacheMode parameter is set to ReadCacheMode.ForceRemote.
Mobile Creatio cannot retrieve the cached data from the data source.

readCacheMode

Sets up how to retrieve data from the cache. By default, ReadCacheMode.Auto.

Available values

ReadCacheMode.Auto	Mobile Creatio can retrieve data from the cache or directly from the data source based on the values of the Mobile application operation mode (`MobileApplicationMode` code) system setting and `updateCache` parameter. We recommend using the `ReadCacheMode.Auto` value regardless of the Mobile application operation mode (`MobileApplicationMode` code) system setting value.
ReadCacheMode.ForceLocal	Mobile Creatio retrieves data from the cache and omits updates in the data source. This is useful if you work in the offline mode or if you want to work with cached data only.
ReadCacheMode.ForceRemote	Mobile Creatio retrieves data directly from the data source, omitting the cache. This is useful if you want to work with up-to-date data only.

cacheDataType

Determines whether to load records fully and set all columns required in the app. By default, CacheDataType.Partial.

Available values

CacheDataType.Partial	Stores only a portion of data in the cache. It is used to load data collection.
CacheDataType.Full	Stores the data in the cache entirely. It is used to load a single record. When you use the `CacheDataType.Full` parameter value, make sure that all required columns are set to the `attributes` parameter.

syncRuleName

Sets up a rule to synchronize the cache. Learn more: SyncRules.

insert()

Adds a record to a data source. A configuration object is a key-value collection.

Parameters

cacheOperation

Manages caching of data added to the data source.

Parameters

updateCache

The flag that specifies whether the insert() operation must retrieve data from the server and write it to the cache. By default, true.

Available values

true	Mobile Creatio caches added data. Mobile Creatio omits the `updateCache: true` parameter value when the `EnableMobileDataAutoSynchronization` additional feature is enabled.
false	Mobile Creatio works with data directly from the cache, omitting the data source.

copy()

Copies the original record from a data source. To add a new record, use the model.insert() method. Specify record ID that identifies a record to copy from the data source and a list of modified values for a new record.

update()

Modifies a record in a data source. A configuration object is a key-value collection.

Parameters

{DataSourceParameters}

An array of parameters that identify a record to modify.

Parameters

type	The parameter type. The `ModelParameterType.PrimaryColumnValue` value marks the parameter as a record ID.
value	The record ID.

cacheOperation

Manages caching of data modified in the data source.

Parameters

updateCache

The flag that specifies whether the update() operation must retrieve data from the server and write it to the cache. By default, true.

Available values

true	Mobile Creatio caches modified data. Mobile Creatio omits the `updateCache: true` parameter value when the `EnableMobileDataAutoSynchronization` additional feature is enabled.
false	Mobile Creatio works with data directly from the cache, omitting the data source.

delete()

Deletes a record from a data source. A configuration object is a key-value collection.

Parameters

{DataSourceParameters}

An array of parameters that identify a record to delete.

Parameters

type	The parameter type. The `ModelParameterType.PrimaryColumnValue` value marks the parameter as a record ID.
value	The record ID.

cacheOperation

Manages caching of data deleted from the data source.

Parameters

updateCache

The flag that specifies whether the delete() operation must retrieve data from the server and write it to the cache. By default, true.

Available values

true	Mobile Creatio caches deleted data. Mobile Creatio omits the `updateCache: true` parameter value when the `EnableMobileDataAutoSynchronization` additional feature is enabled.
false	Mobile Creatio works with data directly from the cache, omitting the data source.
