Question

我想运行更新并为每个更新的资源发布消息。它作为带回调的标准mongoose查询运行时工作正常，但即使将资源输出到流中，也无法使用流产生效果。

var discount = {
    startDate: process.env.START_DATE,
    endDate: process.env.END_DATE,
    funding: process.env.FUNDING, 
    percentage: process.env.PERCENTAGE
}


var connection = mongoose.createConnection(mongoEndpoint, config.mongo);
var Resources = connection.model('Resources', resourcesSchema);
var stream = Resources.update({_id:6375668}, { $push: { discounts: 'blob2' } }, { multi: true });

stream.on('data', function(resource) {
    console.log('Updated resource + published message',resource._id, discount)
    rabbit.publish('index-resource', resource);
});

stream.on('end', function() {
    console.log('Updated all resources in query');
    process.exit(0);
})


var ResourceSchema = module.exports = new Schema({
    _id: Number,
    discounts: Array
}, {versionKey: false});

看起来您的resourcesSchema在这里未定义了吗？

var Resources = connection.model('Resources', resourcesSchema);

使用stream（）时Mongoose不更新
