使用MongoosJS，NodeJS和AngularJS填充嵌套對象

Question

我在獲取模型中的嵌套對象時遇到了問題。 我有一家模特餐廳，我參考了一篇文章。這只是一個演示，我來測試，這是如何工作的，但我沒有得到它.. :(

啊..我用meanjs ..

這裏是我的餐廳模型..

'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); 

這是我第模型

'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); 

這兩種方法都在後臺的NodeJS餐廳控制器：

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(); 
    }); 
}; 

然後，我有一個角度控制器的方法來安全的新餐廳和文章，這是工作。當我訪問"http://localhost:3000/#!/articles"時。但是，當我試圖拿出例如標題，它不起作用。

我創造我的餐廳和文章這樣說：

// 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; 
      }); 
     }; 

這是我創造的觀點：

<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> 

，這是在我的列表視圖

<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> 

的描述在瀏覽器中可見，但對文章沒有任何可見的地方。我如何獲得有關餐館對象中文章的信息？

也許，這是很容易的，但我沒有發現它。在先進

感謝..

Answer 1

，所以我想通了..我怎麼做我製作的一個錯誤文章。我thougt也許這是錯的文章，然後我創建了一個新的crud菜..

首先，我保存這道菜，並在回調我創建餐廳與我從回調響應中獲得的信息。 。這個工作對我來說..

// 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; 
        }); 
       } 
      ); 
     }; 

，當然還有，我在我的服務器控制器來填充這個新菜：

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(); 
    }); 
}; 

，這是我的店型號：

'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' 
    }, 
    dish: { 
     type: Schema.ObjectId, 
     ref: 'Dish' 
    }, 
    art: { 
     title: { 
      type: String, 
      default: 'HelloTitle', 
      trim: true, 
      required: 'Title cannot be blank' 
     }, 
     content: { 
      type: String, 
      default: '', 
      trim: true 
     } 
    } 
}); 

mongoose.model('Restaurant', RestaurantSchema);
