这是 FluentPostGIS 包的一个分支，增加了对地理查询的支持。FluentPostGIS 为 fluent-postgres-driver 和 Vapor 4 提供了 PostGIS 支持。
在你的 Package.swift 文件中，将这行添加到依赖项：
.package(url: "https://github.com/brokenhandsio/fluent-postgis.git", from: "0.3.0")
然后将这行添加到目标（target）的依赖项：
.product(name: "FluentPostGIS", package: "fluent-postgis"),
导入模块
import FluentPostGIS
可选地，你可以添加一个 Migration 来启用 PostGIS
app.migrations.add(EnablePostGISMigration())
添加一个类型到你的模型
final class User: Model {
static let schema = "user"
@ID(key: .id)
var id: UUID?
@Field(key: "location")
var location: GeometricPoint2D
}
然后在 Migration 中使用它的数据类型
struct UserMigration: AsyncMigration {
func prepare(on database: Database) async throws -> {
try await database.schema(User.schema)
.id()
.field("location", .geometricPoint2D)
.create()
}
func revert(on database: Database) async throws -> {
try await database.schema(User.schema).delete()
}
}
| 几何类型 | 地理类型 |
|---|---|
| GeometricPoint2D | GeographicPoint2D |
| GeometricLineString2D | GeographicLineString2D |
| GeometricPolygon2D | GeographicPolygon2D |
| GeometricMultiPoint2D | GeographicMultiPoint2D |
| GeometricMultiLineString2D | GeographicMultiLineString2D |
| GeometricMultiPolygon2D | GeographicMultiPolygon2D |
| GeometricGeometryCollection2D | GeographicGeometryCollection2D |
使用任何过滤器函数进行查询
let eiffelTower = GeographicPoint2D(longitude: 2.2945, latitude: 48.858222)
try await User.query(on: database)
.filterGeographyDistanceWithin(\.$location, eiffelTower, 1000)
.all()
| 查询 |
|---|
| filterGeometryContains |
| filterGeometryCrosses |
| filterGeometryDisjoint |
| filterGeometryDistance |
| filterGeometryDistanceWithin |
| filterGeographyDistanceWithin |
| filterGeometryEquals |
| filterGeometryIntersects |
| filterGeometryOverlaps |
| filterGeometryTouches |
| filterGeometryWithin |
| sortByDistance |
