这可能已经在其他地方得到了不同的回答,但我仍然在下面的案例中苦苦挣扎。
我要寻找的是将所有字段从一个模式(在我的情况下为names
)带到特定位置(即:在features.properties
内部)
字段 features.properties.CNTR_ID 将是我的第二个查询的输入参数,理想情况下以:
结尾names(coutries: [$properties.CNTR_ID]) { }
"properties": {
"CNTR_ID": "RO",
"CNTR_NAME": "România", <- foreign key
"ISO3_CODE": "ROU" <- foreign key
}
这就是我构造 typeDefs 的方式:
type TranslationCountry {
CNTR_ID: String!
CNTR_NAME: String
ISO3_CODE: String
NAME_ENGL: String
}
union PropertyCountryOrRegion = PropertyCountry | PropertyRegion
type PropertyCountry {
CNTR_ID: String!
ISO3_CODE: String!
NAME_ENGL: String!
}
type PropertyRegion {
CNTR_CODE: String!
NUTS_NAME: String!
LEVL_CODE: String!
NUTS_ID: String!
}
scalar Coordinates
type Geometry {
type: String!
coordinates: Coordinates!
}
type Feature {
id: String!
geometry: Geometry!
type: String!
properties: PropertyCountryOrRegion
}
type Region {
category: String!
type: String!
features: [Feature]
fileName: String!
}
type Query {
regions(countries: [String!]!, level: Int, scale: String, year: String): [Region]
names(countries: [String!]!): [TranslationCountry]
}
schema {
query: Query
}
