* Returns the name of the column that stores the lock version for implementing optimistic locking. |

214
|

|
* Optimistic locking allows multiple users to access the same record for edits and avoids |
215
|
|
|
* potential conflicts. In case when a user attempts to save the record upon some staled data |
216
|
|

219
|
|
|
* Optimistic locking is only supported by [[update()]] and [[delete()]]. |
220

221
|
|
|
* To use Optimistic locking: |
222
|
|
|
* |
223
|
|
|
* 1. Create a column to store the version number of each row. The column type should be `BIGINT DEFAULT 0`. |
224
|
|
|
* Override this method to return the name of this column. |
225
|
|
|
* 2. Ensure the version value is submitted and loaded to your model before any update or delete. |
226
|
|
|
* Or add [[\yii\behaviors\OptimisticLockBehavior|OptimisticLockBehavior]] to your model |
227
|
|
|
* class in order to automate the process. |
228
|
|
|
* 3. In the Web form that collects the user input, add a hidden field that stores |
229
|
|
|
* the lock version of the recording being updated. |
230
|
|
|
* 4. In the controller action that does the data updating, try to catch the [[StaleObjectException]] |
231
|
|
|
* and implement necessary business logic (e.g. merging the changes, prompting stated data) |
232
|
|
|
* to resolve the conflict. |
233
|
|
|
* |
234
|
|
|
* @return string the column name that stores the lock version of a table row. |
235
|
|
|
* If `null` is returned (default implemented), optimistic locking will not be supported. |
