当我尝试在项目中运行relay-compiler
时,我从标题中收到错误。我使用graphql-python / graphene-django作为后端graphql服务器。这是我的架构的缩写副本。
from graphene_django import DjangoObjectType
from graphene_django.filter import DjangoFilterConnectionField
from .models import Tree
class TreeNode(DjangoObjectType):
class Meta:
model = Tree
filter_fields = ['owner']
interfaces = (relay.Node,)
class Query(ObjectType):
def resolve_my_trees(self, info):
if not info.context.user.is_authenticated:
return Tree.objects.none()
else:
return Tree.objects.filter(owner=info.context.user)
my_trees = DjangoFilterConnectionField(TreeNode)
tree = relay.Node.Field(TreeNode)
class Query(grove.gql_schema.Query, graphene.ObjectType):
pass
schema = graphene.Schema(query=Query)
通过该设置,我可以在GraphiQL中成功运行以下查询
query {
myTrees {
edges {
node {
id
}
}
}
}
到目前为止一切顺利,但现在我正在尝试构建一个可以使用此查询的客户端组件。
import React from 'react';
import {graphql, QueryRenderer} from 'react-relay';
import environment from '../relay_env'
const myTreesQuery = graphql`
query componentsMyTreesQuery {
edges {
node {
id
}
}
}
`;
export default class App extends React.Component {
render() {
return (
<QueryRenderer
environment={environment}
query={myTreesQuery}
variables={{}}
render={({error, props}) => {
if (error) {
return <div>Error!</div>;
}
if (!props) {
return <div>Loading...</div>;
}
return <div>User ID: {props.edges}</div>;
}}
/>
);
}
}
查询是相同的,但是当我运行relay-compiler --src ./jsapp --schema ./schema.graphql --extensions js jsx
时,我收到错误:
GraphQLParser: Unknown field `edges` on type `Query`.
Source: document `componentsMyTreesQuery` file: `components/index.jsx`.
如果我使用Django .json
管理命令生成的graphaql_schema
架构或.graphql
检索到的get-graphql-schema
架构,则会收到此错误。
我错过了哪一部分?
答案 0 :(得分:1)
我可能会有点迟到,但在我看来,你正试图在模式的根上寻求边缘,片段:
const myTreesQuery = graphql`
query componentsMyTreesQuery {
edges {
node {
id
}
}
}
`;
我认为可以改为:
const myTreesQuery = graphql`
query componentsMyTreesQuery {
myTrees {
edges {
node {
id
}
}
}
}
`;
关键字query
后面的文字是指&#39;查询的名称,而不是架构的根。如果您正在使用Relay Modern(通过使用QueryRenderer,我假设您是),那么编译器应该对您大喊大叫,将片段的名称修改为反映其存储的文件名的内容。
