### Details

The datastore is created automatically.

The datastore is only created when the [process_resource_assignments](api/config/process_resource_assignments.md) config is enabled.

The datastore can be used to modify resource assignments from the code:

~~~js
var assignmentStore = gantt.getDatastore(gantt.config.resource_assignment_store);

assignmentStore.addItem({
    resource_id: 5,
    task_id: 2,
    value: 4
});
assignmentStore.removeItem(assignment.id);
assignmentStore.updateItem(assignment.id);

// after assignments are updated in the datastore, you need 
// to call `updateTaskAssignments` to write changes to the task object:
gantt.updateTaskAssignments(taskId);
~~~
