tastypice展示了here如何列出内容类型和通用外键。我有这个工作,但是你怎么做一个帖子来创建一个具有通用外键的资源?你知道吗
这是我的资源:我现在想创建一个新的活动,同时创建一个新的单凭证奖励或多凭证奖励,然后链接它。如何在TastyPie中实现这一点?你知道吗
class CampaignCreateResource(ModelResource):
"""
API Facet.
"""
user = fields.ToOneField(UserResource, 'user', full=True)
participant_reward = GenericForeignKeyField({
SingleVoucherReward: SingleVoucherResource,
MultiVoucherReward: MultiVoucherResource,
}, 'participant_reward')
class Meta:
queryset = Campaign.objects.all()
resource_name = 'campaign'
allowed_methods = ['post', 'get']
authentication = APIAuthentication().get_authentication()
authorization = UserObjectsOnlyAuthorization()
validation = FormValidation(form_class=CampaignForm)
excludes = ['id', 'participant_reward_object_id']
def hydrate(self, bundle, request=None):
"""
Tastypie uses a 'hydrate' cycle to take serializated data from the client
and turn it into something the data model can use.
"""
bundle.obj.user = get_user_model().objects.get(pk=bundle.request.user.id)
return bundle
