how to use ManytoManyField in djangorestframework

Question

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?

Answer 1

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)
