## Description
|
||
|
|
<section id='description'>
|
||
|
|
Model.remove () es útil para eliminar todos los documentos que coincidan con los criterios dados. Elimine a todas las personas cuyo nombre es "Mary", usando Model.remove (). Pasarlo a un documento de consulta con el conjunto de campos "nombre" y, por supuesto, una devolución de llamada.
|
||
|
|
Nota: Model.remove () no devuelve el documento eliminado, sino un objeto JSON que contiene el resultado de la operación y el número de elementos afectados. No olvide pasarlo a la devolución de llamada done (), ya que lo usamos en las pruebas.
