Fluent验证自定义验证规则

使用 Fluent 验证自定义验证规则

swift
import Fluent
struct User: Model {
    static let schema = "users"
    
    @ID(key: .id)
    var id: UUID?
    
    @Field(key: "name")
    var name: String
    
    @Field(key: "email")
    var email: String
    
    @Field(key: "password")
    var password: String
    
    init() {}
    
    init(id: UUID? = nil, name: String, email: String, password: String) {
        self.id = id
        self.name = name
        self.email = email
        self.password = password
    }
}
extension User {
    static func validateEmail(_ email: String) throws {
        guard email.contains("@") else {
            throw FluentValidationError("Invalid email format.")
        }
    }
    
    static func validatePassword(_ password: String) throws {
        guard password.count >= 8 else {
            throw FluentValidationError("Password must be at least 8 characters long.")
        }
    }
}
let user = User(name: "John Doe", email: "john.doe@example.com", password: "password")
do {
    try user.validate()
    print("User registration is valid.")
} catch let error as FluentValidationError {
    print("User registration failed: \(error.reason)")
} catch {
    print("An error occurred during user registration.")
}
