Python Django REST框架及其组合模型,python,django,django-rest-framework,Python,Django,Django Rest Framework,更新的问题 "results": [ { "ice_code": 1, "iceinfo": [ { ice_name": "Ice Name 1" } ) "ice_maker": "Ice Maker 1" }, { "ice_code": 2, "iceinfo": [ {

更新的问题

"results": [
        {
        "ice_code": 1,
        "iceinfo": [
        {
            ice_name": "Ice Name 1"
        }
        )
        "ice_maker": "Ice Maker 1"
        },
       {
        "ice_code": 2,
        "iceinfo": [
        {
            ice_name": "Ice Name 2"
        }
        )
        "ice_maker": "Ice Maker 2"

        },

我能够让它工作，并更新了下面的代码。但是现在我的问题是如何编辑

iceinfo

中的字段？现在它作为

IceInfo对象返回，而不是作为可编辑字段返回。我只能编辑ice\u代码
和ice\u生成器

老问题
"results": [
        {
        "ice_code": 1,
        "iceinfo": [
        {
            ice_name": "Ice Name 1"
        }
        )
        "ice_maker": "Ice Maker 1"
        },
       {
        "ice_code": 2,
        "iceinfo": [
        {
            ice_name": "Ice Name 2"
        }
        )
        "ice_maker": "Ice Maker 2"

        },

我正在尝试为我们的数据库构建一个API。数据库中的信息分为多个表，所有表的主键都是相同的“Ice code
”
我已经尝试了一个星期的大部分时间来合并这些表，这样我可以从一个url（api.something.com/ice/
）看到ice的列表，从（api.something.com/ice/1
）看到ice的详细视图，将所有表中的信息合并在一起
似乎无论我怎么尝试，我都无法组合表格
这是我到目前为止所得到的东西的草稿。我希望最终能够从前端更新字段。每个表的总行数大约在70-80k之间，它们的列数比这里的要多，但我只是想做一个粗略的工作草案

假设您的目标是序列化许多IceInfo实例，那么IceList的用途是什么？还是你在尝试不同的东西？Rest框架可以将多个对象序列化到一个列表中
您可以通过将queryset传递给序列化程序并给出关键字many=True来实现这一点。请看这里：

结果会是这样
queryset=IceInfoSerializer（IceInfo.objects.all（），many=True）

关于新问题，您应该能够从查询集中编辑它们。到目前为止你试过什么？（你最好就新问题开始一个新话题）
此外，您发布的JSON似乎无效，能否检查您是否正确复制粘贴了它？
在我看来，您不需要IceListSerializer来序列化IceInfo的许多实例，只需使用many=True。你为什么需要冰激凌呢？谢谢你的回复。你能详细说明一下你使用many=True的意思吗？Ice_列表和Ice_信息表都包含更多的列，这就是为什么同时使用IceList和IceInfo的原因。假设您的目标是序列化IceInfo的许多实例，那么IceList的用途是什么？还是你在尝试不同的东西？如果我是对的，您可以通过将queryset传递给序列化程序，并给出关键字many=True来实现这一点。请看这里：我是Django Rest新手，所以我遵循了一个教程，它显示了每个模型的序列化程序，至少我是这样理解的。我的目标是简单地显示列表和ice_代码的详细视图，并在需要时进行更新。我只需要一个表/模型就可以让它正常工作，但当我必须包含另一个表时，它就会一直失败。是否应将IceList
queryset设置为类似queryset=IceListSerializer（IceList.objects.all（），many=True）
？尝试类似queryset=IceInfoSerializer（IceInfo.objects.all（），many=True）的设置。如果不行，请告诉我！
