PostGIS support for fluent-postgres-driver and Vapor 4

Installation

Swift Package Manager

.package(url: "https://github.com/rafaellevy/fluent-postgis.git", .branch("master"))

Setup

Import module

import FluentPostGIS

Optionally, you can add a Migration to enable PostGIS:

app.migrations.add(EnablePostGISMigration())

Models

Add a type to your model

final class UserLocation: Model {
    static let schema = "user_location"
    
    @ID(custom: "id", generatedBy: .database)
    var id: Int?
    @Field(key: "location")
    var location: GeometricPoint2D
}

Then use its data type in the Migration:

struct UserLocationMigration: Migration {
    func prepare(on database: Database) -> EventLoopFuture<Void> {
        return database.schema(UserLocation.schema)
            .field("id", .int, .identifier(auto: true))
            .field("location", GeometricPoint2D.dataType)
            .create()
    }
    func revert(on database: Database) -> EventLoopFuture<Void> {
        return database.schema(UserLocation.schema).delete()
    }
}
Geometric Types Geographic Types
GeometricPoint2D GeographicPoint2D
GeometricLineString2D GeographicLineString2D
GeometricPolygon2D GeographicPolygon2D
GeometricMultiPoint2D GeographicMultiPoint2D
GeometricMultiLineString2D GeographicMultiLineString2D
GeometricMultiPolygon2D GeographicMultiPolygon2D
GeometricGeometryCollection2D GeographicGeometryCollection2D

Queries

Query using any of the filter functions:

let searchLocation = GeometricPoint2D(x: 1, y: 2)
try UserLocation.query(on: conn).filterGeometryDistanceWithin(\.$location, user.location, 1000).all().wait()
Queries
