當我做這樣的事情http://example.com/api/v1/nisit/?format=json。我會得到這個錯誤「模型」有一個空的屬性「頁面」,不允許空值。「如何使用tastypie反向關係
我想使用tastypie的反向關係。與「頁面」模型形成「nisit」模型相反。我想要的結果是調用127.0.0.1:8000/api/v1/nisit/?format=json & friend_ followingPage _id = 1
問題的關鍵是「如何設置followingPage在Nisit屬性模型是在頁面模型反向關係到followingNisit屬性
這是我的模型
class Nisit(models.Model):
friends = models.ManyToManyField('self',null=True,blank=True)
class Page(models.Model):
followingNisit = models.ManyToManyField(Nisit,blank=True)
這是我的資源
class NisitResource(ModelResource):
friend = fields.ManyToManyField('self','friend',null=True)
followingPage = fields.ToManyField('chula.api.resourse.PageResource','followingPage')
class Meta:
queryset = Nisit.objects.all()
resource_name = 'nisit'
filtering = {
'friend' : ALL_WITH_RELATIONS,
'id' : ALL,
}
在上面的代碼中。我嘗試編寫>>>>頁= .................根據這個鏈接http://django-tastypie.readthedocs.org/en/latest/resources.html#reverse-relationships 但它不能幫助
class PageResource(ModelResource):
followingNisit = fields.ManyToManyField(NisitResource, 'followingNisit',null=True)
class Meta:
queryset = Page.objects.all()
resource_name = 'page'
authorization= Authorization()
filtering = {
'followingNisit': ALL_WITH_RELATIONS,
'p_name': ALL,
}
