Question

希望有人能帮助我!! :)

我遵循了这个帖子django-tastypie and many to many "through" relationships，我通过表格成功创建了一个多人关系。

但是我的问题是我无法将数据发布到桌子很多托马尼，让我自己解释一下。

表A. 表B

RelationTable AB

我想发送：{A：{AB：[ab，ab]}}，我在A中发帖，但数据不会保留，即使它没有出错。

下面你可以找到我的代码和我使用的CURL。我想我必须使用save_m2m，但我不知道怎么样!!!!!有人可以指导如何做到这一点，在谷歌找不到好的信息

curl --dump-header - -H "Accept: application/json" -H "Content-Type: application/json"  -X put --data '{"agents":[],"director":"/api/v1/user/5/","disco":"/api/v1/disco/1/","doors":[],"end_date":"2013-05-02T14:41:00","ini_date":"2013-05-02T14:41:00","name":"hrthhrthrth","offers":[{"id":108,"offer":"/api/v1/offer/5/","party":"/api/v1/party/61/","resource_uri":"/api/v1/partyoffer/108/","state":"FALSE","updated_at":"2013-05-19T17:05:03.262410"},{"id":107,"offer":"/api/v1/offer/4/","party":"/api/v1/party/61/","resource_uri":"/api/v1/partyoffer/107/","state":"TRUE","updated_at":"2013-05-19T17:08:08.336766"}],"resource_uri":"/api/v1/party/61/","updated_at":"2013-05-20T19:31:42.256Z","sid":61,"dirty":true}' 'http://127.0.0.1:8001/api/v1/party/61/?username=director1&api_key=ee1ea29c028879f76b690e224d884808232b8e3e'
