destroy

  • Edit on GitHub

Delete an instance from the connection data source

connection.destroy( instance )

To destroy an instance, it's serialized data is passed to destroyData. If destroyData's promise resolves to anything other than undefined, destroyedInstance is called.

Parameters

  1. instance {Instance}:

    the instance being deleted from the data source

Returns

{Promise<Instance>}:

Promise resolving to the same instance that was passed to destroy

Use

To use destroy, create a connection, retrieve an instance, and then call .destroy() with it.

// create a connection
var constructor = require('can-connect/constructor/');
var dataUrl = require('can-connect/data/url/');
var todoConnection = connect([dataUrl, constructor], {
  url: "/todos"
})

// retrieve a todo instance
todoConnection.get({id: 5}).then(function(todo){
  // Call .destroy():
  todoConnection.destroy(todo)
});

.destroy() above will call destroyData on the data/url behavior, which will make an HTTP DELETE request to /todos/5 with the serialized todo data. The server response data may look something like:

{
  deleted: true
}

That response data will be passed to destroyedInstance, which by default adds those properties to todo.
