Question

我已经在grails中创建了新域，并且我已经尝试保存了一个控制器，但没有任何内容保存在数据库中..代码如下

控制器

     def register={
       String name = params.name
       String email = params.email
       String pass = params.password
       boolean signedIn = params.signedIn
       System.out.println(name + " " + email +" "+ pass+" " + signedIn)
       def rUser = new Registered(params)
      rUser.signedIn = signedIn

      System.out.println(rUser)
       rUser.save(flush:true)


   }

域

    class Registered {
    String name;
    String email;
    String password;
    boolean signedIn =false;


    static constraints = {

    }
}

我试图通过此网址保存

http://localhost:8080/egypths/apps/register?name=hegab&email=eio@gmail.com&password=tom&signedIn=false

所以我做错了什么...请记住堆栈跟踪中没有错误

我首先将其包装在一个看起来像这样的集成测试中：

import groovy.util.GroovyTestCase
import org.junit.Test

public class RegisterControllerTests extends GroovyTestCase {

    @Test
    void saveAction() {
        def controller = new RegisterController() //or whatever the controller name is
        controller.params.name = "SomethingUnique"
        controller.params.email = "example@example.com"
        controller.params.password = "password"
        controller.params.signedIn = "false"

        controller.register()

        def registered = Registered.findByName("SomethingUnique")
        assert "example@example.com" == registered.email
        assert "password" == registered.password
        assert false == registered.signedIn
    }
}

然后我首先让你的控制器动作尽可能简单：

def register={
    String name = params.name
    String email = params.email
    String pass = params.password
    boolean signedIn = params.signedIn
    def rUser = new Registered()
    rUser.name = name
    rUser.email = email
    rUser.password = pass
    rUser.signedIn = signedIn

    rUser.save(flush:true, failOnError:true)  //I would remove the failOnError after you identify the issue.
}

通过这种方式，您可以快速重复测试并找出问题所在。将failOnError:true添加到保存调用将导致在未通过验证时抛出异常。如果这个简单的示例工作开始回到更优雅的解决方案，以确定您所处的位置。
