Django Serializers有很多关系 [英] Django Serializers many to many relationship

问题描述

我正在使用Angularjs和Django进行一个小项目。我有两个不同的模型及其相应的终点。

I am working in a small project using Angularjs and Django. I have two different models with its corresponding end points.

class Skills(models.Model):
    skills = models.CharField(max_length=100)

    def __str__(self):
        return self.skills



  class Project(models.Model):
...
    required_skills = models.ManyToManyField(
            Skills, verbose_name="list of skills")
..

这是一个我的技能终点副本

This is a copy of my skills end point

[
    {
        "id": 1,
        "skills": "Css"
    },
    {
        "id": 2,
        "skills": "HTML5"
    },
    {
        "id": 3,
        "skills": "Java"
    }
]

在首页我有一个使用$ http.post服务将数据发送到数据库的表单。当我创建项目时，它可能需要一种技能或多种技能。这是我的困惑来了，我可以通过发送pk来存储我的外键，在这种情况下是pk。但是，由于我处理的是多对多的关系，我无法弄清楚什么是最好的方法。我已经阅读了文档和一些在线资源，但都取得了成功。此外，表单有一个下拉菜单，其中包含技能列表。我使用$ http.get获取此值。请问有谁知道如何解决这个问题？

On the front page I have a form that uses $http.post service to send data to the database. When I project is created, it might require one skill or multiple skills. Here is where my confusion come, I can store I foreign key by sending the pk which in this case is id. However, since I am dealing with a many to many relationship, I can not figure out what is the best way to proceed. I have read the documentation and some online resources with any success. Also, the form has an dropdown menu with the list of skills.I got this values using $http.get. Please anyone has any idea of how to solve this issue?
