deleteAll()
If you need to delete all the entities of a Model, this shortcut query will do just that. It queries the entitites by batches of 500 (maximum set by the Datastore) and delete them then repeat the query.
Disclaimer: this shortcut query hasn't been tested on a very large set of entities so please report any issue you might find.
This method accepts the following arguments:
MyModel.deleteAll(
/* {Array} -- optional. ex: ['ParentEntity', 1234 ] */
<ancestors>,
/* {string} -- optional. A specific namespace */
<namespace>
)
@Returns -- an object with a success and a message properties.
Example:
BlogPost.deleteAll().then((response) => {
console.log(response.success);
});
// With ancestors path and namespace
BlogPost.deleteAll(['Grandpa', 1234, 'Dad', 'keyname'], 'com.dev.new-domain')
.then((response) => {
...
});
