Remove from Collection

Removes an association between two records.

DELETE /:model/:record/:association/:record_to_remove

This action removes a reference to some other record (the "foreign" record) from a collection attribute of this record (the "primary" record).

  • If the foreign record does not exist, it is created first.
  • If the collection doesn't contain a reference to the foreign record, this action will be ignored.
  • If the association is 2-way (i.e. reflexive, with "via" on both sides) the association on the foreign record will also be updated.

Example

Remove Dolly (employee #7) from the employeesOfTheMonth list of store #16.

Using jQuery:

$.delete('/store/16/employeesOfTheMonth/7', function (purchases) {
  console.log(purchases);
});

Using Angular:

$http.delete('/store/16/employeesOfTheMonth/7')
.then(function (purchases) {
  console.log(purchases);
});

Using sails.io.js:

io.socket.delete('/store/16/employeesOfTheMonth/7', function (purchases) {
  console.log(purchases);
});

Using cURL:

curl http://localhost:1337/store/16/employeesOfTheMonth/7 -X "DELETE"

Should return store #16, the primary record:

{
  "employeesOfTheMonth": [],
  "name": "Dolly",
  "createdAt": "2014-08-03T01:16:35.440Z",
  "updatedAt": "2014-08-03T01:51:41.567Z",
  "id": 16
}

Notes

  • This action is for dealing with plural ("collection") associations. If you want to set or unset a singular ("model") association, just use update.
  • The example above assumes "rest" blueprints are enabled, and that your project contains at least an empty 'Employee' model as well as a Store model with association: employeesOfTheMonth: {collection: 'Employee'}. You'll also need at least an empty PurchaseController and EmployeeController. You can quickly achieve this by running:

    $ sails new foo
    $ cd foo
    $ sails generate api purchase
    $ sails generate api employee
    

...then editing api/models/Store.js.
