Question

它显示错误＆＃34; error_message＆＃34;：＆＃34;对于带有基数为10的int（）的无效文字：＆＃39;＆＃39;＆＃34;＆＃39;＆＃39; 我收到针对用户资源的补丁请求的此错误。我的用户模型是

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'

我的用户资源脚本是：

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工作正常，但PATCH和PUT方法不起作用。我正在使用邮递员提出请求因此，对于PATCH请求（http://127.0.0.1:8888/api/user_api/user/14/?format=json）正文将

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

然后我得到500，内部服务器错误。堆栈跟踪是

{
  "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: ''"

}

对于PUT请求，正文将是

{
  "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"
}

为此我也得到500内部服务器错误。堆栈跟踪是：

{
    "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'"

}

我不知道为什么我会得到这些错误。

Answer 1

你的PUT身体有：

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

和您的模型字段：

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

因此您必须使用类似于模型

中指定的数字来生成PUT / PATCH请求

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

在JSON中有效。

希望这有帮助。

问候！
