如何在 django 自定義用戶 model 中使用多對多關系？

Question

我的自定義用戶 Model

from django.contrib.auth.models import AbstractBaseUser,BaseUserManager



class UserManager(BaseUserManager):
    def create_user(self,email, first_name, last_name, role_id, org_id, status, created_by, modified_by, password=None, is_admin=False, is_staff=False):
        if not email:
            raise ValueError("email id is required")

        if not password:
            raise ValueError("password must required")

我正在使用 Django Rest 框架為此用戶 Z20F35E630DAF499FA4C3F688C. 當我嘗試使用下面提到的正文添加用戶時。

{
    "first_name": "FName",
    "last_name": "LName",
    "role_id": 1,
    "org_id": 1,
    "project_id": [1,2],
    "created_by": 1,
    "modified_by": 1,
    "status": "Active",
    "email": "emailaddress@gmail.com",
    "password": "pass12345"
}

我得到 output 作為

{
    "first_name": "FName",
    "last_name": "LName",
    "role_id": 1,
    "org_id": 1,
    "created_by": 1,
    "modified_by": 1,
    "status": "Active",
    "email": "emailaddress@gmail.com",
    "password": "pass12345"
}

項目 ID 未添加到數據庫中，有人可以幫助我解決什么問題嗎？

我正在使用 Djoser 庫添加用戶

http://127.0.0.1:8000/auth/users/

這是 Djoser 中用於創建用戶的端點。

您的create_user()方法中似乎缺少項目分配邏輯。
