SilverStripe 3.6.5 - связывает загруженные файлы из внешней формы SilverStripe с объектом данных

У меня есть объект данных под названием «Project», который имеет отношение $ has_many к другому объекту данных под названием «ProjectExpenseForm». В интерфейсе сайта находится форма SilverStripe, которая используется для обновления некоторых полей проекта. Новые файлы и изображения также можно загружать через интерфейсную форму.

Я использую модуль SilverStripe Dropzone Master (https://github.com/unclecheese/silverstripe-dropzone) для создания поля загрузки в форме внешнего интерфейса. Мне удалось заставить его работать, чтобы он сохранял все загрузки в правильную папку в каталоге ресурсов (у каждого проекта есть папка для загруженных файлов, а настройка - assets / projects / [идентификатор проекта] / files /). Однако я не уверен, как прикрепить / связать эти загруженные файлы с проектом. Хорошо, что они загружаются в нужную папку, но если файлы не связаны с проектом, это нехорошо.

Вот код интерфейсной формы:

public function UpdateMyProjectProfileForm()
{
    $fieldsArr = array();
    $member = Member::currentUser();

    if (!$member) {
        return "<div class='text-danger'>Error: must be logged in to view this page.</div>";
    }
    $request = $this->getRequest();
    $projectName = $request->param('ProjectName');
    $projectNameID = explode("-", $projectName);

    $projectNameID = $projectNameID[0];

    if ($member->inGroup('project-lead')) {
        $project = Project::get()
            ->filter(
                array(
                    "ProjectLeadID" => $member->ID,
                    "ID" => $projectNameID
                )
            )
            ->first();
        $name = ReadonlyField::create('Name', 'Name of Project', $project->Name);
        $firstName = ReadonlyField::create('FirstName', 'First Name of Project Manager', $project->FirstName);
        $lastName = ReadonlyField::create('LastName', 'Last Name of Project Manager', $project->LastName);
        $phone = ReadonlyField::create('Phone', "Phone Number", $project->Phone);
        $emailAddress = ReadonlyField::create('Email', "Manager Email", $project->Email);

        $projectSummary = TextareaField::create('ProjectSummary', "Project Summary", $project->ProjectSummary);
        $imageUploader = FileAttachmentField::create('MyFile', 'Upload a file')
            ->setView('grid')
            ->setMultiple(true)
            ->setFolderName("projects/".$project->ID.'/expenses'); //THIS WORKS - Stores the file(s) uploaded to the proper directory

        array_push($fieldsArr, $name);
        array_push($fieldsArr, $firstName);
        array_push($fieldsArr, $lastName);
        array_push($fieldsArr, $phone);

        array_push($fieldsArr, $projectSummary);
        array_push($fieldsArr, $imageUploader);
        $fields = new FieldList($fieldsArr);

        $updateButton = FormAction::create('update', 'Update')
            ->addExtraClass("btn btn-default commonBtn");

        $actions = new FieldList($updateButton);
        $required = new RequiredFields(
            array('Name', 'Notes', 'ProjectSummary')
        );

        $form = new Form($this, $projectName . '/UpdateMyProjectProfileForm', $fields, $actions, $required);

        $form->setFormMethod('POST', true);

        return $form;
    }
}

public function update($data, Form $form)

        ->filter(
            array(
                "ProjectLeadID" => $member->ID,
                "ID" => $projectNameID
            )
        )
        ->first();

    if ($data['Name'] == "") {
        $form->addErrorMessage("Name", "Project Name is required.", "text-danger");
        return $this->redirectBack();
    }

    if ($data['Notes'] == "") {
        $form->addErrorMessage("Notes", "Notes is required.", "text-danger");
        return $this->redirectBack();
    }

        return $this->redirectBack();
    }

    $member = Member::currentUser();

    if (!$member) {
        $form->addErrorMessage("FirstName", "Error: user profile not found.", "text-danger");
        return $this->redirectBack();
    }

    $project->Name = $data['Name'];
    $project->Notes = $data['Notes'];
