Question

我是Symfony和OOP的新手。

尝试创建一个用户可以上传其活动文件的应用。每个用户都有一个或多个活动。每个活动都只有一个文件。

用户只会上传文件，并且我想要创建一个新的Activity（）;

所以我认为Controller应该是这样的：

详细文件可在此处找到：https://gist.github.com/carambazza/53804469d3021601f1bb

// DashboardController.php
class DashboardController extends Controller
{
    public function indexAction(Request $request)
    {
        $activity = new Activity();

        $form = $this->createForm(ActivityType::class, $activity);
        $form->handleRequest($request);

        // form is valid ...
    }

// ActivityType.php
class ActivityType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('name', TextType::class)
            ->add('description', TextType::class)
            ->add(
                'activityFile',
                CollectionType::class,
                array(
                    'entry_type' => ActivityFileType::class,
                    'allow_add' => true,
                    'allow_delete' => true,
                    'by_reference' => false,
                )
            )
            ->add('save', SubmitType::class, array('label' => 'Upload .fit file'));
    }

// ActivityFileType.php
class ActivityFileType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('file', FileType::class,
                array(
                    "required" => TRUE,
                    "attr" => array(
                        //"accept" => "image/*",
                        "multiple" => true,
                    )
                )
            );
    }

映射是这样的：

// Activity.orm.xml
<?xml version="1.0" encoding="utf-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">
  <entity repository-class="ChartsBundle\Repository\ActivityRepository" name="ChartsBundle\Entity\Activity">

    <id name="id" type="guid" column="id">
      <generator strategy="UUID"/>
    </id>

    <many-to-one field="user" target-entity="User" inversed-by="activities">
      <join-column name="user_id" referenced-column-name="id" />
    </many-to-one>

    <one-to-one field="activityFile" target-entity="ActivityFile">
      <join-column name="activity_file_id" referenced-column-name="id" />
    </one-to-one>

    <!-- other connnections -->

    <!-- all fields -->

  </entity>
</doctrine-mapping>

//ActivityFile.orm.xml
<?xml version="1.0" encoding="utf-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">
  <entity repository-class="ChartsBundle\Repository\ActivityFile" name="ChartsBundle\Entity\ActivityFile">

    <id name="id" type="guid" column="id">
      <generator strategy="UUID"/>
    </id>

    <!-- all fields -->

  </entity>
</doctrine-mapping>

问题：

对象之间的关系是否正常？
如何让文件上传工作并为每个文件创建活动的新实例？用户可以选择多个文件进行上传

Answer 1

对我来说，表格不对。集合类型用于一对多关系，例如，如果您想在编辑用户时向用户内联添加活动。对于一对一的关系，您希望在活动表单中嵌入活动文件的表单，因此您只需要这样而不是集合类型：

$scope.data

你们的关系看起来很正确。建议您的ActivityFile实体的存储库文件名不一致，应该是var myObject = { value: 1 }; var $scope = {}; $scope.data = myObject.value; $scope.data = 3; // This should alert the value of 1 window.alert(myObject.value);，但这是一个小问题。

为每个上传的文件创建新实例
