如何在 djangorestframework 中使用 ManytoManyField
我正在使用 djangorestframework。该模型一次会议可以有许多人参加。 所以我尝试使用 django 的 ManytoManyField：
class Meeting(models.Model):
name=models.CharField(max_length=100)
participates=models.ManyToManyField(Person)
通过 python manager.py sqlall XXX 数据库表是：
CREATE TABLE "OA_meeting_participates" (
"id" integer NOT NULL PRIMARY KEY,
"meeting_id" integer NOT NULL,
"person_id" integer NOT NULL REFERENCES "OA_person" ("id"),
UNIQUE ("meeting_id", "person_id")
)
;
CREATE TABLE "OA_meeting" (
"id" integer NOT NULL PRIMARY KEY,
"name" varchar(100) NOT NULL,
)
问题来了：当我通过选择一些人创建会议时，服务器响应 'participates' 是该函数的无效关键字参数。 因为 OA_meeting 没有参加字段。 那么如何解决呢？
i'm using djangorestframework. the models one meeting could have many participates.
So i tried to use ManytoManyField of django:
class Meeting(models.Model):
name=models.CharField(max_length=100)
participates=models.ManyToManyField(Person)
by python manager.py sqlall XXX the DB tables are:
CREATE TABLE "OA_meeting_participates" (
"id" integer NOT NULL PRIMARY KEY,
"meeting_id" integer NOT NULL,
"person_id" integer NOT NULL REFERENCES "OA_person" ("id"),
UNIQUE ("meeting_id", "person_id")
)
;
CREATE TABLE "OA_meeting" (
"id" integer NOT NULL PRIMARY KEY,
"name" varchar(100) NOT NULL,
)
the problems comes: when i create a meeting by selecting some persons, server response 'participates' is an invalid keyword argument for this function.
since OA_meeting does not have participates field.
so how to solve it?

请参阅许多字段。您需要首先分别创建会议和人员对象，然后执行
meeting.partcipates.add(person)（顺便说一句，我认为您正在寻找的词是participANts）
see the docs on manytomany fields. You need to create the meeting and person objects separately first, and then do
meeting.partcipates.add(person)(btw, i think the word you are looking for is participANts)
