I have a problem with getting nested objects in a model. I have a model restaurant, where i am referencing an article. This is just an demo for me to test how this is working, but i am not getting it.. :(
在模型中获得嵌套对象有问题。我有一家模范餐厅，在那里我引用了一篇文章。这只是我测试它是如何工作的一个演示，但我不明白。:(
ah.. i am using meanjs..
啊. .我用meanjs . .
here is my restaurant model..
这是我的餐厅模型。
'use strict';
/**
* Module dependencies.
*/
var mongoose = require('mongoose'),
Schema = mongoose.Schema;
/**
* Restaurant Schema
*/
var RestaurantSchema = new Schema({
name: {
type: String,
default: '',
required: 'Please fill Restaurant name',
trim: true
},
desc: {
type: String,
default: 'description is here'
},
created: {
type: Date,
default: Date.now
},
user: {
type: Schema.ObjectId,
ref: 'User'
},
article: {
type: Schema.ObjectId,
ref: 'Article'
}
});
mongoose.model('Restaurant', RestaurantSchema);
This is my Article model.
这是我的文章模型。
'use strict';
/**
* Module dependencies.
*/
var mongoose = require('mongoose'),
Schema = mongoose.Schema;
/**
* Article Schema
*/
var ArticleSchema = new Schema({
created: {
type: Date,
default: Date.now
},
title: {
type: String,
default: '',
trim: true,
required: 'Title cannot be blank'
},
content: {
type: String,
default: '',
trim: true
}
});
mongoose.model('Article', ArticleSchema);
this two methods are in the nodejs backend restaurant controller:
这两种方法在nodejs后端餐厅控制器中:
exports.list = function(req, res) { Restaurant.find().sort('-created').populate('article').exec(function(err, restaurants) {
if (err) {
return res.status(400).send({
message: errorHandler.getErrorMessage(err)
});
} else {
res.jsonp(restaurants);
}
});
};
exports.restaurantByID = function(req, res, next, id) { Restaurant.findById(id).populate('article').exec(function(err, restaurant) {
if (err) return next(err);
if (! restaurant) return next(new Error('Failed to load Restaurant ' + id));
req.restaurant = restaurant ;
next();
});
};
I have then an angular controller method to safe a new restaurant and an article, which is working. When i am accessing "http://localhost:3000/#!/articles". But when i am trying to get for example the title out, it is not working.
然后我有一个角控制器方法来保护一个新餐馆和一篇文章，这是有效的。当我访问“http://localhost:3000/#!/articles”时。但是当我试着把题目写出来的时候，它就不管用了。
I am creating my restaurant and article this way:
我正在以这种方式创建我的餐厅和文章:
// Create new Restaurant
$scope.create = function () {
// Create new Restaurant object
var newArticle = new Articles({
title: this.articleTitle
});
newArticle.$save();
var restaurant = new Restaurants({
name: this.name,
desc: this.description,
article: newArticle._id
});
// Redirect after save
restaurant.$save(function (response) {
$location.path('restaurants/' + response._id);
// Clear form fields
$scope.name = '';
}, function (errorResponse) {
$scope.error = errorResponse.data.message;
});
};
this is in my create view:
这是在我的创建视图中:
<div class="controls">
<input type="text" data-ng-model="name" id="name" class="form-control" placeholder="Name" required>
<input type="text" data-ng-model="articleTitle" id="article" class="form-control" placeholder="artikel" required>
<input type="text" data-ng-model="description" id="description" class="form-control" placeholder="desription" required>
</div>
and this is in my list view
这在列表视图中
<h4 class="list-group-item-heading" data-ng-bind="restaurant.name"></h4>
<h3 class="list-group-item-heading" data-ng-bind="restaurant.article"></h3>
<h3 class="list-group-item-heading" data-ng-bind="restaurant.desc"></h3>
the description is visible in the browser, but, nothing visible about the article. How do i get the information about the article in the restaurant object?
描述在浏览器中是可见的，但是文章中没有任何内容是可见的。如何获得关于餐厅对象中的文章的信息?
Probably, this is very easy, but i did not find it out..
很可能，这很容易，但我没有发现。
thanks in advanced..
由于先进的. .

so i figured it out.. i made a mistake of how i am creating the article. I thougt maybe it was something wrong with article, then i created a new crud dish..
所以我想到了…我在写这篇文章时犯了一个错误。我觉得这可能是商品的问题，所以就做了一道新菜。
first, i am saving the dish, and in the callback i am creating the restaurant with the information i got from the callback response.. this worked for me..
首先，我正在保存这道菜，在回调中，我正在用从回调响应中得到的信息创建餐馆。这个工作对我来说. .
// Create new Restaurant
$scope.create = function () {
// Create new Restaurant object
var dishId = 0;
var thisObject = this;
var newDish = new Dishes({
name: this.dishName
});
newDish.$save(function(response){
console.log('XX in $save: %s', response._id);
dishId = response._id;
var restaurant = new Restaurants({
name: thisObject.name,
desc: thisObject.description,
art: {
title: thisObject.artTitle,
content: thisObject.artContent
},
dish: dishId
});
// Redirect after save
restaurant.$save(function (response) {
$location.path('restaurants/' + response._id);
// Clear form fields
$scope.name = '';
}, function (errorResponse) {
$scope.error = errorResponse.data.message;
});
}
);
};
and of course, i have to populate this new dish in my server controller:
当然，我必须在我的服务器控制器中填充这个新盘子:
exports.list = function(req, res) { Restaurant.find().sort('-created').populate('dish').exec(function(err, restaurants) {
if (err) {
return res.status(400).send({
message: errorHandler.getErrorMessage(err)
});
} else {
res.jsonp(restaurants);
}
});
};
exports.restaurantByID = function(req, res, next, id) { Restaurant.findById(id).populate('dish').exec(function(err, restaurant) {
if (err) return next(err);
if (! restaurant) return next(new Error('Failed to load Restaurant ' + id));
req.restaurant = restaurant ;
next();
});
};
and this is my restaurant model:
这是我的餐厅模型:
