Destroy (blueprint)
Delete the record specified by id from the database forever and notify subscribed sockets.
DELETE /:model/:id
This destroys the record that matches the id parameter and responds with a JSON dictionary representing the destroyed instance. If no model instance exists matching the specified id, a 404 is returned.
Additionally, a destroy event will be published to all sockets subscribed to the record room, and all sockets currently subscribed to the record will be unsubscribed from it.
Parameters
| Parameter | Type | Details |
|---|---|---|
| model | The identity of the containing model. e.g. 'purchase' (in /purchase/7) |
|
| id (required) |
The primary key value of the record to destroy, specified in the path. e.g. '7' (in /purchase/7) . |
Example
Delete Pinkie Pie:
DELETE /user/4
Expected response
{
"name": "Pinkie Pie",
"hobby": "kickin",
"id": 4,
"createdAt": 1485550644076,
"updatedAt": 1485550644076
}
Socket notifications
If you have WebSockets enabled for your app, then every client subscribed to the destroyed record will receive a notification where the event name is that of the model identity (e.g. user), and the “message” has the following format:
verb: 'destroyed',
id: <the record primary key>,
previous: <a dictionary of the attribute values of the destroyed record (including populated associations)>
For instance, continuing the example above, all clients subscribed to User #4 (except for the client making the request) might receive the following message:
id: 4,
verb: 'destroyed',
previous: {
name: 'Pinkie Pie',
hobby: 'kickin',
createdAt: 1485550644076,
updatedAt: 1485550644076
}
If the destroyed record had any links to other records, there might be some additional notifications:
Assuming the record being destroyed in our example had an association with a via, then either updated or removedFrom notifications would also be sent to any clients who are subscribed to those child records on the other side of the relationship. See Blueprints > remove from and Blueprints > update for more info about the structure of those notifications.
If the association pointed at by the
viais plural (e.g.cashiers), then theremovedFromnotification will be sent. Otherwise, if theviapoints at a singular association (e.g.cashier) then theupdatednotification will be sent.
