Question

我有一个包含多个自包含的mongoose模型文件的项目。我有另一个modelprovider，它使用模型名称和请求来执行操作。我想将操作挂钩到'find'的前面

模型文件

'use strict';

// load the things we need
var mongoose = require('mongoose');
var config = require('../../config/environment');
var auth_filter = require('../../auth/acl/lib/queryhook');
var modelProviders = require('../../auth/acl/lib/modelprovider');
var invoice_db = mongoose.createConnection(config.mongo.url + '/invoiceDB'); //connect to buyer DB
var path = require('path');


// define the schema for our invoice details model
var invoicedetailSchema = new Schema({
    //SCHEMA INFO
});

var InvoiceModel = invoice_db.model('InvoiceDetail', invoicedetailSchema);


//REGISTER THE HOOKS TO THE MDOEL
auth_filter.registerHooks(InvoiceModel);

promise.promisifyAll(InvoiceModel);
promise.promisifyAll(InvoiceModel.prototype);
module.exports = InvoiceModel;

modelProviders().setModel(InvoiceModel.modelName, path.resolve(__dirname, __filename) );

我知道查找的钩子和findOne只能在模式级别工作，但我想在模型级别完成。

registerhooks

'use strict';

var hooks = require('hooks'),
    _ = require('lodash');
var mongoose = require('mongoose');


    exports.registerHooks = function( model) {

        var Qry = mongoose.Query;
        var query = model.find();
        var Sch = mongoose.Schema;
        var schema = model.schema

        _.assign(model, hooks);
        model.hook('find', mongoose.model.prototype.find)
        model.pre('find', function(next){
            console.log('hell')
            return next()
        })
        console.log(model)
    };
    exports.registerHooks_ = function( model) {
        var Qry = mongoose.Query;
        var query = model.find();
        var Sch = mongoose.Schema;
        var schema = model.schema

        _.assign(schema, hooks);
        schema.hook('find', query)
        schema.pre('find', function(next){
            console.log('hell')
            return next()
        })
        console.log(schema)
    };

我知道文档建议在架构级别进行前置和后置，但有没有办法使用钩子库或钩子库来解决这个问题。

我想将它保持在模型级别的原因是我需要在'find'预钩子上访问模型名称。如果有办法这样做，那就太棒了

挂钩到现有mongoose.model的最佳方法是什么
