獲得來自API調用用戶在Django tastypie創建一個對象

Question

我有以下型號

from django.contrib.auth.models import User 
... 
class Experiment(models.Model): 
""" Experiment class """ 
date = models.DateTimeField(auto_now=True, auto_now_add=True) 
user = models.ForeignKey(User) 

和下面的資源

class UserResource(ModelResource): 

    class Meta: 
     queryset = User.objects.all() 
     resource_name = 'user' 
     authorization = DjangoAuthorization() 
     excludes = ['id', ] 
     allowed_methods = ['get', ] 



class ExperimentResource(ModelResource): 
    user = fields.ToOneField(UserResource, 'user') 

    class Meta: 
     queryset = Experiment.objects.all() 
     resource_name = 'experiment' 
     authentication = ApiKeyAuthentication() 
     authorization = DjangoAuthorization() 
     excludes = ['id', ] 

    def hydrate_user(self, bundle): 
     bundle.obj.user = bundle.request.user 
     return bundle 

但是，當我使用POST請求和ApiKeyAuthentication創建新實驗用戶字段保持空白，即使我爲用戶字段提供保溼。

我使用的Django tastypie 0.11

Answer 1

這是因爲bundle.obj.user不是用戶模式，但SimpleLazyObject。

嘗試更換，

def hydrate_user(self, bundle): 
    bundle.obj.user = bundle.request.user 
    return bundle 

用，

def hydrate_user(self, bundle): 
    user = User.objects.get(pk=bundle.request.user.pk) 
    bundle.obj.user = user 

    return bundle 

或者，如果用戶不總是請求，請確保您發送有效resource_uri爲用戶模型，例如，/api/v1/user/1/
