我有一个名为'Project'的数据对象，它与另一个名为'ProjectExpenseForm'的数据对象有$ has_many关系。在网站的前端是SilverStripe表单，用于更新项目的某些字段。新文件和图像也可以以前端形式上传。
我正在使用名为SilverStripe Dropzone Master（https://github.com/unclecheese/silverstripe-dropzone）的模块在前端表单上创建上传字段。我设法让它工作，以便将所有上传保存到assets目录中的正确文件夹（每个Project都有一个上传文件的文件夹，设置是assets / projects / [project id] / files /）。但是我不确定如何将这些上传的文件附加/关联到项目。将它们上传到正确的文件夹是好的，但如果文件与项目没有关联，那就不好了。
以下是前端表单的代码：
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);
$notes = TextareaField::create('Notes', 'Notes', $project->Notes);
$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, $emailAddress);
array_push($fieldsArr, $notes);
array_push($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)
{
$member = Member::currentUser();
$request = $this->getRequest();
$projectName = $request->param('ProjectName');
$projectNameID = explode("-", $projectName);
$projectNameID = $projectNameID[0];
$project = Project::get()
->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 $this->redirectBack();
}
if ($data['ProjectSummary'] == "") {
$form->addErrorMessage("ProjectSummary", "Project Summary is required.", "text-danger");
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'];
$project->ProjectSummary = $data['ProjectSummary'];
$project->write();
$form->sessionMessage("Project profile successfully updated.", 'text-success');
return $this->redirectBack();
}

答案 0 :(得分：1)
您需要将关系传递给File AttachmentField而不是'MyFile'
$imageUploader = FileAttachmentField::create('MyFile', 'Upload a file')
在您的情况下，它是AdditionalProjectImages，因为您在has_many中将其命名为。
private static $has_many = array(
'AdditionalProjectImages' => 'Image'
)
他们应该指向图像类而不是AdditionalProjectImage。
所以你的FileAttachmentField应该是这样的：
$imageUploader = FileAttachmentField::create('AdditionalProjectImages', 'Upload a file')
由于每个$ has_many需要一个$ has_one，你需要在图像类上有一个。所以你需要一个扩展名：
ImageExtension extends Image
{
public static $has_one = [
'ProjectImages' => 'Project'
];
}
运行dev / build / flush如果你这样做，Silverstripe会将这些上传的文件附加/关联到你的Project。

答案 1 :(得分：0)
因为您知道将文件保存到assets/projects/[project id]/files/的文件夹，并且文件对于该项目是唯一的，所以您可以遍历文件并使用DB::query将它们与项目相关联。< / p>
在update文件的UpdateMyProjectProfileForm方法中，我会做类似的事情。
$folderPath = 'assets/projects/' . $projectNameID . '/files/';
$folder = DataList::create('Folder')->filter('Filename', $folderPath)->first();
if ($folder) {
$images = DataList::create('Image')->filter('ParentID', $folder->ID);
foreach ($images as $image) {
DB::query('INSERT INTO Project_AdditionalProjectImages (ProjectID, AdditionalProjectImagesID) VALUES (' . $projectNameID . ',' . $image->ID . ')');
}
}
您可能还希望将ProjectLeadID添加到查询中以使其更安全。您必须检查您的表名称，因为Project_AdditionalProjectImages可能不正确。
