Cascade Delete though remove middleware

[jonah...@gmail.com]

I'm wondering if Mongoose.js supports cascade deletes in the the pre or post remove middleware. For instance if I have a TODO app and a user deleted there account would it also delete everything associated with that user account if I had something like this set up?

userSchema = new Schema({email: String})

userSchema.post('remove', function() {

  TodoList = require('todo_list');

  TodoList.remove({user: this._id} )

})

mongoose.model("User", userSchema)

todoSchema = new Schema({user: {type:ObjectId, ref:"User"}})

todoSchema.post('remove', function() {

  TodoItem = require('todo_item');

  TodoItem.remove({list: this._id} )

});

mongoose.model("ToDoList", todoSchema)

todoItemSchema = new Schema({list: {type:ObjectId, ref:"ToDoList"}})

todoItemSchema.post('remove', function() {

  console.log('DELETED') // <<---- this should be triggered when the user is deleted

});

mongoose.model("ToDoItem", todoItemSchema)

 

Just to sum things up if a user deletes their account the ToDoList associated with that account are deleted & since the ToDoList is deleted the ToDoItems associated with the list are deleted.

Thanks.
