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: $ids) {
ok
}
}
`;
在后端我使用石墨烯,突变如下:
class UpdateSlots(graphene.Mutation):
class Arguments:
disabled = graphene.Boolean(required=True)
printEntry = graphene.Boolean(required=True)
ids = graphene.String(required=True)
ok = graphene.Boolean()
@staticmethod
def mutate(root, info, disabled, printEntry, ids):
pdb.set_trace()
ok = False
try:
ok = True
for id in ids:
print(id)
except Exception as e:
ok = False
raise GraphQLError(str(e))
但我在ids variable
得到如下字符串:
"['3692', '3695', '3704']"
代替 :
['3692', '3695', '3704']
如何发送一组id,如何在后端获取?
任何的想法?
问题是因为ids
是String
类型。
在你的schema
中,ids
论证的类型是String
,所以为了能够拥有像['3692', '3695', '3704']
这样的东西,你必须将参数定义为List
的Strings
。
就像是:
class UpdateSlots(graphene.Mutation):
class Arguments:
disabled = graphene.Boolean(required=True)
printEntry = graphene.Boolean(required=True)
ids = graphene.List(graphene.String(required=True))
在变异中你还必须将param ids
更新为:
const UPDATE_SLOTS = gql`
mutation updateSlots($disabled: Boolean!, $printEntry: Boolean!, $ids: [String]!) {
updateSlots(disabled: $disabled, printEntry: $printEntry, ids: $ids) {
ok
}
}
`;
希望能帮助到你。
