我正在使用 graphene-django 作为 api。我正在尝试创建一个突变来创建一个具有公司外键的品牌。当我改变时，我收到以下错误“'input' 是 print() 的无效关键字参数”。我不明白为什么会抛出这个错误。
这是我的突变
class BrandInput(graphene.InputObjectType):
company = graphene.List(CompanyInput)
name = graphene.String()
website = graphene.String()
description = graphene.String()
country = graphene.String()
city = graphene.String()
address = graphene.String()
class CreateBrand(graphene.Mutation):
class Arguments:
input = BrandInput(description="These fields are required", required=True)
class Meta:
description = "Create Brand Mutation"
errors = graphene.String()
brand = graphene.Field(BrandNode)
@staticmethod
def mutate(root, info, **args):
print('args', args, **args)
if not info.context.user.is_authenticated:
return CreateBrand(errors=json.dumps('Please Login to list your brand'))
try:
company = models.Company.objects.get(slug=args.get('input')['company'])
if company:
brand = models.Brand.objects.create(
company=company,
name=args.get('input')['name'],
slug = args.get('input')['slug'],
website = args.get('input')['website'],
description = args.get('input')['description'],
country = args.get('input')['country'],
city = args.get('input')['city'],
address = args.get('input')['address'],
)
return CreateBrand(brand=brand, errors=null)
except models.Company.DoesNotExist:
return CreateBrand(errors=json.dumps('Company should be required'))
我对 company = graphene.List(CompanyInput) 感到怀疑，所以我将其更改为 company = graphene.String() 并提供了公司的名称，所以我可以在改变品牌时找到公司实例。但是我得到了同样的错误。
突变查询是
mutation {
createBrand(input: {company: "wafty-company", name: "Wafty Brand", website: "www.wafty.com", description: "Wafty brand description", country: "Nepal", city: "Kathmandu", address: "Baneshwor", pinCode: "44600", operationDate: "2018-10-02 15:32:37", franchisingDate: "2018-10-02 15:32:37", numberOfFranchises: "0-10", numberOfOutlets: "0-10"}) {
errors
brand {
name
slug
website
}
}
}
最佳答案
当您尝试将像这样的参数 **args 传递给 print() 时，此参数将被解压缩为关键字参数，这将引发错误，因为 print() 不期望像 mutate() 方法那样的参数。所以你需要删除**args:
print('args', args)
关于python - 'input' 是 print() 的无效关键字参数，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/52612286/
