錯誤與POST請求Tastypie API

Question

我碰到下面的錯誤，當我做一個POST請求Tastypie API：

{"error_message": "", "traceback": "Traceback (most recent call last):\n\n File \"/home/kelp/lib/python2.7/django_tastypie-0.9.11-py2.7.egg/tastypie/resources.py\", line 195, in wrapper\n response = callback(request, *args, **kwargs)\n\n File \"/home/kelp/lib/python2.7/django_tastypie-0.9.11-py2.7.egg/tastypie/resources.py\", line 407, in dispatch_list\n return self.dispatch('list', request, **kwargs)\n\n File \"/home/kelp/lib/python2.7/django_tastypie-0.9.11-py2.7.egg/tastypie/resources.py\", line 436, in dispatch\n response = method(request, **kwargs)\n\n File \"/home/kelp/lib/python2.7/django_tastypie-0.9.11-py2.7.egg/tastypie/resources.py\", line 1194, in post_list\n updated_bundle = self.obj_create(bundle, request=request, **self.remove_api_resource_names(kwargs))\n\n File \"/home/kelp/webapps/goals/goals/main/api.py\", line 191, in obj_create\n bundle = super(JoinedGoalResource, self).obj_create(bundle, request, user=request.user)\n\n File \"/home/kelp/lib/python2.7/django_tastypie-0.9.11-py2.7.egg/tastypie/resources.py\", line 1839, in obj_create\n bundle = self.full_hydrate(bundle)\n\n File \"/home/kelp/lib/python2.7/django_tastypie-0.9.11-py2.7.egg/tastypie/resources.py\", line 716, in full_hydrate\n value = field_object.hydrate(bundle)\n\n File \"/home/kelp/lib/python2.7/django_tastypie-0.9.11-py2.7.egg/tastypie/fields.py\", line 643, in hydrate\n value = super(ToOneField, self).hydrate(bundle)\n\n File \"/home/kelp/lib/python2.7/django_tastypie-0.9.11-py2.7.egg/tastypie/fields.py\", line 152, in hydrate\n elif self.attribute and getattr(bundle.obj, self.attribute, None):\n\n File \"/home/kelp/webapps/goals/lib/python2.7/django/db/models/fields/related.py\", line 301, in __get__\n raise self.field.rel.to.DoesNotExist\n\nDoesNotExist\n"} 

如何使這種錯誤的意識？

，使Django的回溯感的最好方法是開始在底部和向上移動，直到你到一些代碼，是你的。一般來說Django是非常穩固的，通常的問題是你正在做的：

文件\ 「/家/海帶/ webapps /下的目標/目的/主/ api.py \」，線路191，在 obj_create \ ñ捆綁=超（JoinedGoalResource，個體經營）.obj_create（束， 請求，用戶= request.user）

很可能要傳遞到基準的建立和試圖解決的一個外鍵關係不好的對象。

我不能看到它從你發佈什麼，但你可以看看在追溯這最後一項，看看它的對象在看，它是訪問什麼關係不存在。該提示的是，它的東西與你的捆綁對象和一個壞場做。
