I am getting a MongoDB error when trying to insert a subdocument. The subdocs already have unique _ids, but an error is being thrown for a different, non-unique field that I don't want unique.
The error in Angular is: "Assets.serial already exist". How can I make this field contain duplicate values, and what is causing the model to assume it should be unique?
Here is my Mongoose model:
'use strict';
var mongoose = require('mongoose'),
Schema = mongoose.Schema;
var AssetUrlSchema = new Schema({
name: {
type: String,
unique: false,
default: '',
trim: true
},
url: {
type: String,
unique: false,
default: 'http://placehold.it/75x75',
trim: true
},
}),
AssetSchema = new Schema({
serial: {
type: Number,
unique: false
},
urls: {
type: [AssetUrlSchema],
unique: false,
default: [
{ name: '', url: 'http://placehold.it/75x75' },
{ name: '', url: 'http://placehold.it/75x75' }
]
}
}),
/**
* Item Schema
*/
ItemSchema = new Schema({
name: {
type: String,
default: '',
required: 'Please enter name',
trim: true
},
assets: {
type: [AssetSchema],
default: [],
unique: false
},
property: {
type: Schema.ObjectId,
zd: 'Please select a property',
ref: 'Property'
},
created: {
type: Date,
default: Date.now
},
user: {
type: Schema.ObjectId,
ref: 'User'
}
});
mongoose.model('Item', ItemSchema);
And here is my 'save' method:
function(){
var i = 0, assets = [];
for (;i < 24;i++) {
assets.push({
serial: 1000+i,
urls: {
name: 'Asset Name ' + i,
url: 'http://placehold.it/75x75?'
}
});
}
item = new Items ({
name: 'FPO',
property: newPropId,
assets: assets
});
return item.$save(
function(response){ return response; },
function(errorResponse) {
$scope.error = errorResponse.data.message;
}
);
}
The first time I insert a document, it works fine. Any subsequent time, it fails with a 400 because the assets.serial field is not unique. However, I am specifically marking that field as unique:false.
The error in the mode console is:
{ [MongoError: insertDocument :: caused by :: 11000 E11000 duplicate key error index: mean-dev.items.$assets.serial_1 dup key: { : 1000 }]
name: 'MongoError',
code: 11000,
