Question

我正在尝试在数据库中存储帖子图像，并且正在使用dropzonejs。我能够在存储位置存储图像，这意味着图像可以成功移动存储文件夹。但是当我存储在数据库中时，发生了奇怪的问题。Laravel在数据库中只插入了一些图像吗？

例如，我上传了10张图像，所有文件都移到了存储文件夹中，但是在数据库中仅显示了3条记录？或有时是两个或四个。

该如何解决？

Dropzone配置

Dropzone.options.mDropzoneTwo = {
        paramName: "images",
        maxFiles: 10,
        maxFilesize: 2, // MB
        url: '../../media/store',
        method: 'POST',
        headers: {
            "X-CSRF-TOKEN": token,
        },
        uploadMultiple: true,

        accept: function (file, done) {
            done();
        },

        init: function() {
            this.on("sending", function(file, xhr, formData){
                formData.append("post_type", post.dataset.type);
                formData.append("post_id", post.dataset.id);
            });
        },

        success: function () {
            console.log(this.files[0].xhr.responseText)
        }
    };

AdminController

public function storePostMedia(Request $request)
{
    // trying to get model by post type, there are several models depending by post types
    $table = $request->get("post_type");
    $model = getModel($table);
    // finding post
    $post = $model->find($request->get("post_id"));
    $media = new Media;
    // store images
    foreach ($request->file("images") as $image){
        $new_media = $media->storePostImages($image);
        $post->media()->save($new_media);
    }
}

storePostImages（）方法

public function storePostImages($file)
{
    // get image - rename - storage to storage folder
    $realName = str_slug(pathinfo($file->getClientOriginalName(), PATHINFO_FILENAME));
    $extension = $file->getClientOriginalExtension();
    $new_name = str_slug($realName) . "-" . time() . "." . $extension;
    $fullPath = \Storage::putFileAs("posts", $file, $new_name);
    // save to database
    $this->name = $new_name;
    $this->path = $fullPath;

    return $this;
}

我为每个记录创建新的模型实例解决了我的问题

foreach ($request->file("images") as $image){ 
    $media = new Media;
    $new_media = $media->storePostImages($image);
    $post->media()->save($new_media);
}

多态关系-无法将所有文件存储在数据库中吗？
