Django Tastypie - 包括很多領域

Question

我想用django tastypie但有一些麻煩。這裏是我的api.py：

from tastypie.resources import ModelResource 
from tastypie import fields 
from app.models import First, Second, Third 

class FirstResource(ModelResource): 
    second = fields.ToManyField('app.api.SecondResource', 'second_set', related_name='first', null=True, blank=True, full=True) 

    class Meta: 
     queryset = First.objects.all() 
     resource_name = 'first' 

class SecondResource(ModeResource): 
    first = fields.ForeignKey(FirstResource, 'first', full=True) 
    third = fields.ToManyField('app.api.ThirdResource', 'third_set', related_name='second', null=True, blank=True, full=True) 

    class Meta: 
     queryset = Second.objects.all() 
     resource_name = 'second' 

class ThirdResource(ModelResource): 
    poll = fields.ForeignKey(SecondResource, 'second', full=True) 

    class Meta: 
     queryset = Third.objects.all() 
     resource_name = 'third' 

當我試着使用http://127.0.0.1:8000/app/api/v1/second/它包括FirstResource得到SecondResource，但我也希望相關的ThirdResource。 現在它只給我一個空的數組。我怎樣才能做到這一點？

嘗試在你的第三個模型添加相關的名稱：

class Third(models.Model): 
    second = models.ForeginKey(Second, related_name=thirds) 

然後在資源：

class SecondResource(ModeResource):` 
     first = fields.ForeignKey(FirstResource, 'first', full=True) 
     third = fields.ToManyField('app.api.ThirdResource', 'thirds', null=True, blank=True, full=True)
