我有两个模型Place和Tag。我在tag.js中创建了creteTag（）远程方法，我想在place.js中访问此函数。
tag.js
'use strict';
var request = require('request');
module.exports = function(Tag) {
Tag.crateaTag = function(name, callback) {
request({
method: 'POST',
url: 'http://localhost:3000/api/tags',
body:{
"name": name
},
json: true
},
function (error, response,body) {
if (error || response.statusCode != 200) {
console.log('Hiba' + error + ' \n' + response);
}
callback(error, body);
});
};
place.js
'use strict';
var request = require('request');
module.exports = function(Place) {
var app = require('../../server/server');
Place.createPlace = function(name, descreption, tagName, callback) {
var Tag = app.models.Tag; //???
request({
method: 'POST',
url: 'http://localhost:3000/api/tags',
body:{
"name": name,
"descreption": descreption,
"tag": Tag.createTag(tagName) //???
},
json: true
},
function (error, response, body) {
if (error || response.statusCode != 200) {
console.log('Hiba' + error + ' \n' + response);
}
callback(error, body);
});
};
};
我想在数据库中发布想要查看单独集合的标签。

在 tag.js 中将 #: import FadeTransition kivy.uix.screenmanager.FadeTransition
# Reference main.py
#: import main main
#: import Slider kivy.uix.slider
#: import ActionBar kivy.uix.actionbar
#: import Window kivy.core.window

声明为远程方法：
crateaTag在 place.js 中，将Tag.remoteMethod('crateaTag', {
accepts: {
arg: 'name',
type: 'string',
required: true
},
description: "create a tag"
});
用作：
Tag
