Django的tastypie補丁給了我一個「500」錯誤

Question

它顯示錯誤「ERROR_MESSAGE」：「與基地10個無效字面INT（）：‘’」 我收到此錯誤補丁請求，用於用戶的資源。我的用戶模型是

class User(AbstractBaseUser): 

    VIA_FACEBOOK = 1 
    VIA_GOOGLE = 2 

    SIGN_IN_TYPES = (
     (VIA_FACEBOOK,'facebook'), 
     (VIA_GOOGLE,'google') 
    ) 

    MALE = 1 
    FEMALE = 0 

    GENDERA_TYPES = (
     (FEMALE,'female'), 
     (MALE,'male') 
     ) 

    SINGLE_ACCOUNT_USER = 0 
    JOINT_ACCOUNT_USER = 1 


    USER_TYPES = (
     (SINGLE_ACCOUNT_USER,'single_accout_user'), 
     (JOINT_ACCOUNT_USER,'joint_accout_user') 

    ) 
    first_name = models.CharField(blank = True, max_length=50) 
    middle_name = models.CharField(blank=True, max_length=50,null=True) 
    last_name = models.CharField(blank=True, max_length=50,null=True) 
    email = models.EmailField(blank=False,unique=True,max_length=100) 
    sign_in_via = models.SmallIntegerField(choices=SIGN_IN_TYPES, default=0) 
    mobile = models.CharField(blank=True, max_length=10,null=True) 
    dob = models.DateField(blank=True, null=True) 
    profile_pic_url = models.CharField(blank=True,max_length=300,null=True) 
    background_pic_url = models.CharField(blank=True,max_length=300,null=True) 
    gender = models.SmallIntegerField(blank=True,choices=GENDERA_TYPES,null=True) 
    user_type = models.SmallIntegerField(blank=False,choices=USER_TYPES,default=0) 
    details = models.CharField(blank=True,max_length=500,null=True) 
    created_on = models.DateTimeField(auto_now=True) 
    slug = models.SlugField(default='') 

    USERNAME_FIELD = 'email' 

我的用戶資源腳本是：

class UserResource(ModelResource): 
    class Meta: 
     queryset = User.objects.all() 
     resource_name = 'user' 
     list_allowed_methods = ['get', 'post', 'patch', 'put','delete'] 
     authorization = Authorization() 
     include_resource_uri = True 
     always_return_data = True 
     authentication = Authentication() 
     filtering = { 
      'id': ALL, 
      'email': ALL, 
      'user_type': ALL, 
      'mobile': ALL, 
      'created_at': ALL, 
     } 
     excludes = ['created_on','password','last_login','sign_in_via'] 

GET和POST都工作正常，但PATCH和PUT方法不工作。 我想提出使用郵差 這樣的請求，對一個PATCH請求（http://127.0.0.1:8888/api/user_api/user/14/?format=json）身體會

{ 
    "background_pic_url": "h/h", 
    "last_name":"sdfsd" 
} 

然後我得到一個500，內部服務器錯誤。堆棧跟蹤

{ 
    "error_message": "invalid literal for int() with base 10: ''", 
    "traceback": "Traceback (most recent call last): 

    File \"C:\\Python27\\lib\\site-packages\\tastypie\\resources.py\", line 220, in wrapper 
    response = callback(request, *args, **kwargs) 

    File \"C:\\Python27\\lib\\site-packages\\tastypie\\resources.py\", line 460, in dispatch_detail 
    return self.dispatch('detail', request, **kwargs) 

    File \"C:\\Python27\\lib\\site-packages\\tastypie\\resources.py\", line 483, in dispatch 
    response = method(request, **kwargs) 

    File \"C:\\Python27\\lib\\site-packages\\tastypie\\resources.py\", line 1669, in patch_detail 
    bundle = self.full_dehydrate(bundle) 

    File \"C:\\Python27\\lib\\site-packages\\tastypie\\resources.py\", line 885, in full_dehydrate 
    data[field_name] = field_object.dehydrate(bundle, for_list=for_list) 

    File \"C:\\Python27\\lib\\site-packages\\tastypie\\fields.py\", line 146, in dehydrate 
    return self.convert(current_object) 

    File \"C:\\Python27\\lib\\site-packages\\tastypie\\fields.py\", line 255, in convert 
    return int(value)\n\nValueError: invalid literal for int() with base 10: ''" 

} 

和PUT請求，身體會

{ 
    "email":"a@a.com", 
    "first_name":"a", 
    "middle_name":"b", 
    "last_name":"c", 
    "mobile":"1234567890", 
    "details":"nothing", 
    "profile_pic_url":"n/n", 
    "background_pic_url":"v/v", 
    "sign_in_via":"1", 
    "dob":"2017-01-29", 
    "user_type":"1", 
    "gender":"2" 
} 

這也是我收到500內部服務器錯誤。堆棧跟蹤是：

{ 
    "error_message": "'dict' object has no attribute 'first_name'", 
    "traceback": "Traceback (most recent call last): 

    File  \"C:\\Python27\\lib\\site-packages\\tastypie\\resources.py\", line 220, in wrapper 
    response = callback(request, *args, **kwargs) 

    File \"C:\\Python27\\lib\\site-packages\\tastypie\\resources.py\", line 460, in dispatch_detail 
    return self.dispatch('detail', request, **kwargs) 

    File \"C:\\Python27\\lib\\site-packages\\tastypie\\resources.py\", line 483, in dispatch 
    response = method(request, **kwargs) 

    File \"C:\\Python27\\lib\\site-packages\\tastypie\\resources.py\", line 1472, in put_detail 
    updated_bundle = self.obj_update(bundle=bundle, **self.remove_api_resource_names(kwargs)) 

    File \"C:\\Python27\\lib\\site-packages\\tastypie\\resources.py\", line 2226, in obj_update 
    bundle = self.full_hydrate(bundle) 

    File \"C:\\Python27\\lib\\site-packages\\tastypie\\resources.py\", line 939, in full_hydrate 
    setattr(bundle.obj, field_object.attribute, value)\n\nAttributeError: 'dict' object has no attribute 'first_name'" 

} 

我不知道爲什麼即時得到這些錯誤。

Answer 1

你PUT身體有：

{ 
    ... 
    "user_type": "1", 
    "gender": "2" 
} 

和模型領域：

gender = models.SmallIntegerField(blank=True,choices=GENDERA_TYPES,null=True) 
user_type = models.SmallIntegerField(blank=False,choices=USER_TYPES,default=0) 

所以就像你在模型中指定你必須與號碼PUT/PATCH請求太

{ 
    ... 
    "user_type": 1, 
    "gender": 2 
} 

這個在JSON中有效。

希望這會有所幫助。

問候！
