Properties Detailed

exception

Returns last occurred exception on this record (or null).

Type Exception The occurred exception.

Sample

var exception = record.exception;

foundset

Returns parent foundset of the record.

Type JSFoundSet The parent foundset of the record.

Sample

var parent = record.foundset;

recordMarkers

Returns the validation object if there where validation failures for this record Can be set to null again if you checked the problems, will also be set to null when a save was successful.

Type JSRecordMarkers The last validation object if the record was not validated.

Sample

var recordMarkers = record.recordMarkers;

Methods Detailed

createMarkers()

Creates and returns a new validation object for this record, which allows for markers to be used outside the validation flow. Will overwrite the current markers if present. Can be set to null again if you checked the problems, will also be set to null when a save was successful.

Returns: JSRecordMarkers A new validation object.

Sample

var recordMarkers = record.createMarkers();

getChangedData()

Returns a JSDataSet with outstanding (not saved) changed data of this record. column1 is the column name, colum2 is the old data and column3 is the new data.

NOTE: To return an array of records with outstanding changed data, see the function databaseManager.getEditedRecords().

Returns: JSDataSet a JSDataSet with the changed data of this record.

Sample

/** @type {JSDataSet} */
var dataset = record.getChangedData()
for( var i = 1 ; i <= dataset.getMaxRowIndex() ; i++ )
{
	application.output(dataset.getValue(i,1) +' '+ dataset.getValue(i,2) +' '+ dataset.getValue(i,3));
}

getDataSource()

Returns the records datasource string.

Returns: String The datasource string of this record.

Sample

var ds = record.getDataSource();

getPKs()

Returns an array with the primary key values of the record.

Returns: Array an Array with the pk values.

Sample

var pks = foundset.getSelectedRecord().getPKs() // also foundset.getRecord can be used

hasChangedData()

Returns true if the current record has outstanding/changed data.

Returns: Boolean true if the current record has outstanding/changed data.

Sample

var hasChanged = record.hasChangedData();

isDeleted()

Returns true if the current record is a deleted record or false otherwise. The deletion has not been done in the database itself.

Returns: Boolean true if the current record is a deleted record, false otherwise;

Sample

var isNew = foundset.getSelectedRecord().isDeleted();

isEditing()

Returns true or false if the record is being edited or not.

This will not check if the record doesn't really have any changes, it just returns the edit state. So this can return true but databaseManager.getEditedRecord() will not return this record because that call will check if the record has really any changed values compared to the stored database values. Record can be in edit mode without changes when some field is focused (so edit is started) but no changes are done yet or when changes were done in such a way that record data is the same as database data.

Returns: Boolean a boolean when in edit.

Sample

var isEditing = foundset.getSelectedRecord().isEditing() // also foundset.getRecord can be used

isNew()

Returns true if the current record is a new record or false otherwise. New record means not saved to database.

Returns: Boolean true if the current record is a new record, false otherwise;

Sample

var isNew = foundset.getSelectedRecord().isNew();

isRelatedFoundSetLoaded(relationName)

Returns true or false if the related foundset is already loaded. Will not load the related foundset.

Parameters

• String relationName name of the relation to check for

Returns: Boolean a boolean when loaded.

Sample

var isLoaded = foundset.getSelectedRecord().isRelatedFoundSetLoaded(relationName)

revertChanges()

Reverts the in memory outstanding (not saved) changes of the record.

Returns: void

Sample

var record= foundset.getSelectedRecord();
record.revertChanges();

save()

Saves the in memory outstanding (not saved) changes of the record and stops its editing.

Returns: Boolean true if the save was done without an error.

Sample

var record= foundset.getSelectedRecord();
record.save();
