Question

我正在使用Feathers JS框架和mongoose库来创建Web服务，但是当我想启动我的项目时，我收到此错误消息：

 Mongoose option.lean is false. Use hook.results.toObject() to convert the results to JS objects
Calling populate(target, options) is now DEPRECATED and will be removed in the future

代码：

  var mongooseService = require('feathers-mongoose');

 app.use('user', mongooseService({
     name: 'user',
     Model: require('./../models/user'),
     id: 'cuid'
   }))

   .use('post', mongooseService({
     name: 'post',
     Model: require('./../models/post'),
   }))

 var getLastPost = function() {
   return app.service('post').find({
     query: {
       "status": {
         $in: [0, 1, 2]
       },
       $select: ['version', '_id']
     }
   });
 };
 app.service('post')
   .before(getLastPost)
   .after(hooks.populate('user', {
     service: 'user'
   }))

我有什么办法要删除此错误消息吗？

定义服务时需要添加精益属性。

 var mongooseService = require('feathers-mongoose');

 app.use('user', mongooseService({
     "name": 'user',
     "Model": require('./../models/user'),
     "id": 'cuid',
     "lean": true
   }))

   .use('post', mongooseService({
     "name": 'post',
     "Model": require('./../models/post'),
     "lean": true
   }))

 var getLastPost = function() {
   return app.service('post').find({
     query: {
       "status": {
         $in: [0, 1, 2]
       },
       $select: ['version', '_id']
     }
   });
 };
 app.service('post')
   .before(getLastPost)
   .after(hooks.populate('user', {
     create: function(hook, next) {
        hook.result = hook.result.toObject();
        next();
     },
     service: 'user'
   }))

修复第二条消息错误：

 var auk = require('feathers-hooks-common');
   var populate = function(serviceName,name,parentFieldName,childFieldName){
   return auk.populate({
      schema: {
      include: {
        service: serviceName,
        nameAs: name,
        parentField: parentFieldName,
        childField: childFieldName
      }
    }
  })
  }
  app.service('post').hooks({
    after: {all: populate("user","user","user","_id")}
  });

FeatherJS错误消息：调用populate（目标，选项）现在已弃用
