Public Properties ​
Property | Description |
---|---|
behaviors | yii\base\Behavior – List of behaviors attached to this component. |
db | craft\db\Connection, array, string – The database connection to use |
deleteAllTrashed | boolean – Whether hardDelete() should delete all soft-deleted rows, rather than just the ones that were deleted long enough ago to be ready for hard-deletion per the config5:softDeleteDuration config setting. |
probability | integer – The probability (parts per million) that garbage collection (GC) should be performed on a request. |
silent | boolean – Whether CLI output should be muted. |
db
​
- Type
- craft\db\Connection, array, string
- Default value
'db'
- Since
- 4.0.0
The database connection to use
deleteAllTrashed
​
- Type
- boolean
- Default value
false

probability
​
- Type
- integer
- Default value
10
The probability (parts per million) that garbage collection (GC) should be performed on a request. Defaults to 10, meaning 0.001% chance.
This number should be between 0 and 1000000. A value 0 means no GC will be performed at all unless forced.
silent
​
- Type
- boolean
- Default value
false
- Since
- 5.4.9
Whether CLI output should be muted.
