如何开发到phpMyAdmin的迁移

我在将“cover\u image”迁移到phpmyAdmin时遇到问题。每次我尝试上传照片时,都会出现一个错误:

SQLSTATE[42S22]:未找到列:“字段列表”中的1054未知列“cover\u images”

下面是我的代码:

if($request->hasFile('cover_image')) {
    //get``
    $fileNameWithExt = $request->file('cover_image')->getClientOriginalName();

    //get filename
    $filename = pathinfo($fileNameWithExt, PATHINFO_FILENAME);

    //get ext
    $extension = $request->file('cover_image')->getClientOriginalExtension();

    $fileNameToStore = $filename.'_'.time().'.'.$extension;

    //upload image
    $path = $request->file('cover_image')->storeAs('public/cover_images', $fileNameToStore);
} else {
    $fileNameToStore = 'noimage.jpg';
}

//Create Post
$post = new Post;
$post->title = $request->input('title');
$post->body = $request->input('body');
$post->user_id = auth()->user()->id;
$post->cover_images = $fileNameToStore;
$post->save();

return redirect('/posts')->with('success', 'Post Created');
