Hibernate的关系和AngularJS [英] Hibernate relations and AngularJS

问题描述

我在Hibernate中的游客和行程之间的关系：

如果我想创建一个旅客一个新的跳闸1 下，我参观路线的 /前端/＃/跳闸创建/ 1 并在这里我有一个表格：

              ＆LT; / MD-输入容器＆GT;
            ＆LT; / DIV＆GT;

通过访问 $ routeParams.id 我可以得到的旅行者的细节1 喜欢的的firstName（=马塞尔），的lastName 的也 traveler_id 的

  $ scope.traveler = TravelerFactory.show（{ID：$ routeParams.id}）;
 

这是在旅行者对象的例子。它包含了所有在行程 旅行者迄今取得：

<$p$p><$c$c>[{\"traveler_id\":1,\"company_id\":0,\"account\":false,\"firstName\":\"Marcel\",\"middleName\":null,\"lastName\":\"Schmitt\",\"gender\":null,\"trips\":[],\"email\":null}]

我的问题：

1. 我怎么能与我的旅行者1 与新创建之旅

   [{\"trip_id\":2,\"traveler\":null,\"currency\":null,\"rate\":100,\"description\":\"Flug\",\"dateCreated\":null}]




2. 这是映射关系基本概念的正确方法？

解决方案

想想你的REST服务。

旅客信息URL（旅行者对象）：

  /旅行/：ID  - ＆GT; ＃/旅行/ 1
 

新的旅游（旅行对象）：

  /旅行/：ID /创建 - ＆GT; ＃/旅行/ 1 /创建
 

现有旅游URL（旅行对象）：

  /旅行/：ID /旅游/：travel_id  - ＆GT; ＃/旅行/ 1 /旅行/ 123
 

编辑现有的旅游URL（旅行对象）：

  /旅行/：ID /旅游/：travel_id /编辑 - ＆GT; ＃/旅行/ 1 /旅行/ 123 /编辑
 

所以，你添加新的旅行后，获得成功的调用带回了新的旅游标识（例如：travel_id = 456），并重定向到＃/旅行/ 1 /旅行/ 456

我相信你一定能改善的是，仅仅例如

I have this relation between Travelers and Trips in Hibernate:

If I want to create a new trip for traveler 1, I visit the route /frontend/#/trip-creation/1 and here I have a form:

[excerpt of the template]

        <form novalidate="novalidate" class="form-horizontal">
          <md-content class="md-padding">
            <div layout layout-sm="column">
              <md-input-container flex>
                <label>Vorname</label>
                <input ng-model="traveler.firstName" disabled>
              </md-input-container>
              <md-input-container flex>
                <label>Nachname</label>
                <input ng-model="traveler.lastName" disabled>
              </md-input-container>
            </div>
            <div layout layout-sm="column">
              <md-input-container flex>
                <label>Wert</label>
                <input required type="number" step="any" name="rate" ng-model="trip.rate" min="0" max="9999999">
              </md-input-container>
              <md-input-container flex>
                <md-select ng-model="trip.currency" placeholder="€">
                  <md-option ng-value="currency" ng-repeat="currency in getCurrencies()">{{currency}}</md-option>
                </md-select>
              </md-input-container>
            </div>
            <div layout layout-sm="column">
              <md-input-container flex>
                <label>Beschreibung</label>
                <textarea ng-model="trip.description" columns="1" md-maxlength="150"></textarea>
              </md-input-container>
            </div>
...

By accessing the $routeParams.id I can get the details for traveler 1 like firstName (= Marcel) , lastName and also traveler_id.

$scope.traveler = TravelerFactory.show({id: $routeParams.id});

That is an example for the Traveler object. It contains all the Trips a Traveler had made so far:

[{"traveler_id":1,"company_id":0,"account":false,"firstName":"Marcel","middleName":null,"lastName":"Schmitt","gender":null,"trips":[],"email":null}]

My question:

1. How can I relate my traveler 1 with the new created trip

   [{"trip_id":2,"traveler":null,"currency":null,"rate":100,"description":"Flug","dateCreated":null}]

2. Is this a proper way of mapping the realtions?

Thank you!

解决方案

Think about your REST services.

traveler info URL (traveler object):

/traveler/:id  ->  #/traveler/1

new travel (traveler object):

/traveler/:id/create  ->  #/traveler/1/create

existing travel URL (travel object):

/traveler/:id/travel/:travel_id  ->  #/traveler/1/travel/123

edit existing travel URL (travel object):

/traveler/:id/travel/:travel_id/edit  ->  #/traveler/1/travel/123/edit

So, after you add new travel, get successful call back with new travel id (for example: travel_id=456), and redirect to #/traveler/1/travel/456

I am sure you can improve that, just example
