关于 Django drf 的反序列化一对多字段问题
資深大佬 : endpain 5
大家好，我在使用 django drf 的时候遇到了一个问题，找了一堆资料，暂时还没找到好的解决方法，希望有懂的兄弟可以给指点一下。非常感谢。
models.py
class ProjectStatusModels(models.Model): name = models.CharField(max_length=150,verbose_name='状态名称',unique=True,db_index=True) def __str__(self): return self.name class Meta: verbose_name = '项目状态管理表' ordering = ('-id',) class ProjectModels(models.Model): project_id = models.CharField(verbose_name='项目编号',max_length=120,unique=True,db_index=True) name = models.CharField(verbose_name='项目名称',max_length=150) customer_name = models.CharField(verbose_name='客户名称',max_length=150,null=True,blank=True) evaluation = models.IntegerField(verbose_name='项目估价',null=True,blank=True) start_date = models.DateField(verbose_name='项目开始日期',null=True,blank=True) expiration_date = models.DateField(verbose_name='项目截止日期',null=True,blank=True) sales_name = models.ForeignKey(EmployeeModels,on_delete=models.DO_NOTHING,verbose_name='销售经理',null=True,blank=True) status = models.ForeignKey(ProjectStatusModels,on_delete=models.DO_NOTHING,verbose_name='状态',null=True,blank=True,db_index=True) create_time = models.DateTimeField(verbose_name='发布时间', auto_now_add=True) update_time = models.DateTimeField(verbose_name='修改时间', auto_now=True) def __str__(self): return self.name class Meta: verbose_name = '项目管理表' ordering = ('-id',) view.py

class ProjectStatusModelsSerializers(serializers.ModelSerializer): # 项目状态序列化器 class Meta: model = project_models.ProjectStatusModels fields = '__all__' class ProjectModelsSerializers(serializers.ModelSerializer): # 项目序列化器 class Meta: model = project_models.ProjectModels fields = '__all__' depth = 1 在项目 查询的时候可以返回如下的字段
{ "status_code": 20000, "code": 0, "data": [ { "id": 5, "status": null, "project_id": "asdasdasd", "name": "123123123", "customer_name": "Abcd", "evaluation": null, "start_date": null, "expiration_date": null, "create_time": "2021-04-04T23:17:58.433641", "update_time": "2021-04-04T23:17:58.433666", "sales_name": null }, { "id": 4, "status": null, "project_id": "sss03", "name": "qweqqweasd", "customer_name": "", "evaluation": 10000, "start_date": null, "expiration_date": null, "create_time": "2021-04-04T23:17:03.571699", "update_time": "2021-04-04T23:17:03.571714", "sales_name": null }, { "id": 3, "status": null, "project_id": "sss01", "name": "asasas", "customer_name": "", "evaluation": null, "start_date": null, "expiration_date": null, "create_time": "2021-04-04T23:15:31.134011", "update_time": "2021-04-04T23:15:31.134029", "sales_name": null }, { "id": 2, "status": { "id": 2, "name": "End" }, "project_id": "0002", "name": "s0002", "customer_name": "微创医疗 111", "evaluation": 500, "start_date": "2021-04-04", "expiration_date": "2021-05-11", "create_time": "2021-04-04T22:43:18.374238", "update_time": "2021-04-05T11:39:18.852015", "sales_name": { "id": 5, "code": "0003", "name": "endpein", "phone": "", "birthday": "2021-04-02", "age": 18, "on_the_job": true, "identity_card": "", "work_id": "", "work_id_date": null, "work_id_expiry_date": null, "dormitory_address": "", "passport_id": "", "passport_expiry_date": null, "multiskill_expiry": null, "csoc_expiry": null, "multiskill_category": "[]", "bank_details": "", "email": "[email protected]", "remarks": "哈哈哈", "nationality": null } }, { "id": 1, "status": { "id": 6, "name": "asdasd" }, "project_id": "0001", "name": "s01 项目", "customer_name": "微创医疗", "evaluation": 1000, "start_date": "2021-04-29", "expiration_date": "2021-04-30", "create_time": "2021-04-04T22:42:51.462897", "update_time": "2021-04-05T14:34:03.122631", "sales_name": null } ] } 但是前端传来的数据如下 ,这个数据是 request.data 输出的
<QueryDict: {'csrfmiddlewaretoken': ['ntdydSUNRztDKOKmDSST36oFnSokUFVJG0t9YLXXvQtm6hyYOPT3WHMRPahy6kz8'], 'id': ['1'], 'name': ['s01 项目'], 'project_id': ['0001'], 'customer_name': ['微创医疗'], 'evaluation': ['1000'], 'start_date': ['2021-04-29'], 'expiration_date': ['2021-04-30'], 'status': ['2'], 'sales_name': ['']}> 但是当 ser.is_valid() 在输入 validated_data 的时候 表中 status、sales_name这 2 个一对多的 ForeignKey 字段就没有了。输出变成了如下样式：
ser.validated_data: OrderedDict([('project_id', '0001'), ('name', 's01 项目'), ('customer_name', '微创医疗'), ('evaluation', 1000), ('start_date', datetime.date(2021, 4, 29)), ('expiration_date', datetime.date(2021, 4, 30))]) 请问一下，各位高手应该如何修改和调整呢？
