FeatherJS错误消息:现已弃用调用populate(target，options)
FeatherJS错误消息:现已弃用调用populate(target，options)
提问于 2018-05-30 18:19:03
我正在使用Feathers框架和mongoose库来创建web服务，但是当我想启动我的项目时，我得到了这个错误消息：
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'
}))要删除此错误消息，我需要做些什么吗？

修复第二条消息错误的步骤：
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")}

在定义服务时，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'
