如何将ID列表发送为使用GraphQl的param



我正在使用React,GraphQl和Apollo。

我的功能如下:

updateSlots(updateSlots, data){
        const {slotIds, refetch} = this.props;
        const {disabled, printEntry, toggleSlotForm} = data;
        updateSlots({variables: {disabled: disabled, printEntry: printEntry, ids: slotIds}})
            .then(res => {
                if (res.data.updateSlots.ok) {
                    refetch();
                    this.setState({hasError: false, errorMessage: "", saved: true, slot: initialSlot()}, () => {
                        setTimeout(() => toggleSlotForm(), 3000)
                    });
                }
            })
            .catch(err => {
                debugger;
                let error_msg = err.message.replace("GraphQL error: ", '');
                this.setState({hasError: true, saved: false, errorMessage: error_msg});
                throw(error_msg);
            })
    }

mutation如下:

const UPDATE_SLOTS = gql`
  mutation updateSlots($disabled: Boolean!, $printEntry: Boolean!, $ids: String!) {
    updateSlots(disabled: $disabled, printEntry: $printEntry, ids: $ids) {
        ok
    }
  }
`;

在后端我使用石墨烯,突变如下:

class UpdateSlots(graphene.Mutation):
    class Arguments:
        disabled = graphene.Boolean(required=True)
        printEntry = graphene.Boolean(required=True)
        ids = graphene.String(required=True)
    ok = graphene.Boolean()
    @staticmethod
    def mutate(root, info, disabled, printEntry, ids):
        pdb.set_trace()
        ok = False
        try:
            ok = True
            for id in ids:
                print(id)
        except Exception as e:
            ok = False
            raise GraphQLError(str(e))

,但我在ids variable中得到字符串如下:

"['3692', '3695', '3704']"

而不是:

['3692', '3695', '3704']

如何发送一系列ID,如何在后端获得它?

有什么想法?

问题是因为ids是类型String

在您的schema中,参数ids的类型是String,因此,为了能够拥有诸如['3692', '3695', '3704']之类的东西,您必须将参数定义为StringsList

类似:

class UpdateSlots(graphene.Mutation):
    class Arguments:
        disabled = graphene.Boolean(required=True)
        printEntry = graphene.Boolean(required=True)
        ids = graphene.List(graphene.String(required=True))

,在突变中,您还必须将param ids更新为:

const UPDATE_SLOTS = gql`
  mutation updateSlots($disabled: Boolean!, $printEntry: Boolean!, $ids: [String]!) {
    updateSlots(disabled: $disabled, printEntry: $printEntry, ids: $ids) {
        ok
    }
  }
`;
