Django - 如何在URL中定义外键创建POST？ [英] Django - How can I create POST with foreign key defined in URL?

问题描述

我想知道如何使用定义的ID创建对象POST。我们假设我有一个例子表用户与列 id ，名称和表对象与列 id ， id_users ， sth 其中 id_users 是 id 的外键用户表。我想要这样的URL / users / {id} / object ，我想在URL中为用户定义ID创建对象。
例如这是我的URL / users / 1 / object （ url（r'^ users /（？P< myID& 0-9] +）/ object / $'，views.UserObject） - 应该是okey）和POST的正文：

I wonder how can I create object POST with defined ID. Let's assume that I have for instance table User with columns id,name and table Object with columns id,id_users,sth where id_users is a foreign key of id from User table. I would like to have such URL /users/{id}/object and I would like to create object for user with defined ID in URL. For example this is my URL /users/1/object (url(r'^users/(?P<myID>[0-9]+)/object/$', views.UserObject) - should be okey) and body of POST:

 {
      "id": 2,
      "sth": 123
 }

在这种情况下，它应该添加到我的数据库中：

In this case it should be added to my database:

{
  "id": 2,
  "id_users": 1,
  "sth": 123
}

对于用户与 id 等于 1 我们创建了对象与 id 等于 2 和 sth 等于123.

For User with id equals 1 we have created object with id equals 2 and sth equals 123.

我不知道我的看法应该是什么样的？
我一直以这种方式执行 POST

I don't know what my view should look like? I always did POST in this way:

@api_view(['GET', 'POST'])
def ObjectList(request):

    if request.method == 'POST':
        serializer = ObjectSerializer(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

我已经删除了重复的帖子，因为我已经在这里解释了数据库和表之间的关系看起来像。我也指出了我想要实现的目标。
任何建议如何处理？

I have deleted duplicated posts, because I have explained here how my database and relations between tables look like. I also specified what I would like to achieve. Any suggestions how can I deal with this?

推荐答案

像这样：

@api_view（['GET'，'POST']）

@api_view(['GET', 'POST'])

def object_list(request, myID):

    if request.method == 'POST':
        serializer = ObjectSerializer(data=request.data)
        if serializer.is_valid():
            serializer.save(id_users=myID)
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
