将包含注释的变量发送到视图后，我只能显示用户ID。这就是为什么我需要以某种方式遍历所有注释，并根据它们的user_id来添加具有username-username的新密钥对值，然后将其发送到视图。不幸的是，我在弄清楚该怎么做时遇到麻烦。
public function specificImage($id){
$similarImages = null;
$image = Image::with('comments.user')->find($id);
$subImages = Image::where('parent_id', $id)->get();
$views = $image->views;
$image->views = $views + 1;
$image->save();
$authorId = $image->user_id;
$author = User::find($authorId);
$comments = Comment::where('image_id', $id)->get();
$recentImages = Image::where('parent_id', NULL)->where('user_id', $authorId)->orderBy('created_at', 'desc')->limit(9)->get();
$tag = Tag::whereHas('images', function($q) use ($id) {
return $q->where('taggable_id', $id);
})->first();
if (!empty($tag)) {
$tagId = $tag->id;
}
if (!empty($tagId)) {
$similarImages = Image::where('parent_id', NULL)->whereHas('tags', function($q) use ($tagId) {
return $q->where('tag_id', $tagId);
})->orderBy('created_at', 'desc')->limit(9)->get();
}
return view('specificImage', ['image' => $image,'subImages' => $subImages, 'recentImages' => $recentImages, 'similarImages' => $similarImages, 'author' => $author, 'comments' => $comments]);
}
表格：

答案 0 :(得分：3)
我建议也将user关系添加到您的Comment模型中：
class Comment extends Model
{
public function image()
{
return $this->belongsTo('App\Image');
}
public function user()
{
return $this->belongsTo('App\User');
}
}
然后您可以eager load关系，然后在刀片文件中访问它们：
public function specificImage($id)
{
$image = Image::with('comments.user')->find($id);
return view('specificImage', ['image' => $image]);
}
然后在刀片文件中，您将得到类似的内容：
@foreach($image->comments as $comment)
{{ $comment->user->username }}
@endforeach
