Таблица 57-2. Options for this driver
| Option | Type | Description | Default Value |
|---|---|---|---|
| fields | array | Which data fields to fetch from the datasource. An empty array means: all fields. Form: array(field1, field2, ...) | array() |
| generate_columns | bool | Generate Structures_DataGrid_Column objects with labels. See the 'labels' option. DEPRECATED: use Structures_DataGrid::generateColumns() instead | false |
| labels | array | Data field to column label mapping. Only used when 'generate_columns' is true. Form: array(field => label, ...) DEPRECATED: use Structures_DataGrid::generateColumns() instead | array() |
| params | array | Placeholder parameters for prepare/execute | array() |
| primary_key | array | Name(s), or numerical index(es) of the field(s) which contain a unique record identifier (only use several fields in case of a multiple-fields primary key) | null |
| view | string | The view from $sql array in your DB_Table object. This option is required. | null |
| where | string | A where clause for the SQL query. | null |
If you use aliases in the select part of your view, the count() method from DB_Table and, therefore, $datagrid->getRecordCount() might return a wrong result. To avoid this, DB_Table uses a special query for counting if it is given via a view that needs to be named as '__count_' followed by the name of the view that this counting view belongs to. (For example: if you have a view named 'all', the counting view needs to be named as '__count_all'.)
To use update() and delete() methods, it is required that the indexes are properly defined in the $idx array in your DB_Table subclass. If you have, for example, created your database table yourself and did not setup the $idx array, you can use the 'primary_key' option to define the primary key field.
