我正在将 GraphQL 应用程序从使用 Postgraphql 3.10 和 Postgresql 9.6 版数据库迁移到使用 postgraphile 4.7.0 版和 Postgresql 11 版数据库。
下面的 graphql 查询曾经在旧版本中工作,但在新版本中失败。
query supplier($id: Int!) {
supplierById(id: $id) {
id accountId
title intro description
imageBg imageProfile imageProfileRot
rating status
productsBySupplierId(condition: {published: true, deleted: false}) {
nodes {
id type prodTitle prodDescr
price currency duration { hours minutes }
}
}
reviewsBySupplierId(condition: {target: SUPPLIER}) {
nodes {comment rating createdAt}
}
}
}
失败是因为条件过滤器和错误消息说:
"GraphQLError: Field \"published\" is not defined by type ProductCondition."
"GraphQLError: Field \"deleted\" is not defined by type ProductCondition."
"GraphQLError: Field \"target\" is not defined by type ReviewCondition."
我找不到任何关于如何设置数据库表来支持这种情况的文档。我是否需要将已发布、删除和定位的字段添加到 postgraphile 的某个索引以支持此条件?
