"Object {} has no method 'cast' error" when trying to add item to mongoose array

Question

I'm trying to create a todo app using node.js, mongoose and backbone for learning purposes. Up till now I defined these models: ``` var TaskSchema = new mongoose.Schema({ title: { type:String }, content: { type:String } , created: {type:Date, 'default':Date.now}, due: {type:Date}, accountId: {type:mongoose.Schema.ObjectId} }); var Task = mongoose.model('Task',TaskSchema); var AccountSchema = new mongoose.Schema({ email: { type:String, unique: true}, password: { type:String } , name: { first: {type:String}, last: { type:String } }, birthday: { day: {type:Number, min:1, max:31, required:false}, month: {type:Number, min:1, max:12, required:false}, year: {type:Number} }, photoUrl: {type:String}, biography:{type:String}, tasks:[Task] }); var Account = mongoose.model('Account',AccountSchema); ``` In addition, I also have the following method for adding a task: ``` var enter_new_task = function(options,callback){ var title = options.title; var content = options.content; var due = options.due…

Accepted Answer

The error is in the AccountSchema definition. A subdocument type should be a schema, not a model.

```
var AccountSchema = new mongoose.Schema({
    //...
    tasks:[TaskSchema]
});
```
