我有以下两种型号。它们通过从TextMission表到Mission表的OneToOneField关系“任务”链接。

有时候任务会有相应的TextMission，但并非总是如此。当我在shell中创建/更新对象时，我能够使一切正常工作，但是当有一个TextMission（PUTing为/ mission / {id} /）时，TastyPie只能正确处理请求。当text_mission = null时，它就会崩溃。

我的tastypie配置：

#Models.py
class Mission(models.Model):
    name = models.CharField(max_length = 40)

class TextMission(models.Model):
    mission = models.OneToOneField(Mission, related_name="text_mission", primary_key = True)

当将以下JSON返回给服务器时（我收到的JSON完全相同），我得到一个ValueError：

失败

{“name”：“TEST”，“id”：“1”，“text_mission”：null，“resource_uri”： “/ api / web / mission / 1 /”，} *** ValueError：无法分配无：“Mission.text_mission”不允许空值。

成功

{“name”：“TEST”，“id”：“1”，“text_mission”：{“id”：“1”，“resource_uri”：“/ api / web / text_mission / 1 /”}， “resource_uri”： “/ api / web / mission / 1 /”，}

我的代码中是否存在我做错的事情，或者它不应该以这种方式工作。我在这里不知所措。

我正在运行TastyPie 0.9.11。

Answer 1

我最终搞清楚了，这是一个非常愚蠢的错误。除了null = True之外，我只需要添加blank = True：

class MissionResource(ModelResource):
    text_mission = fields.ToOneField('path.to.TextMissionResource', attribute='text_mission', related_name='mission', full = True, blank = True, null = True)

这使一切正常。

如何在TastyPie中使用null相关资源POST到服务器？

失败

成功
