更新我的Post模型时,我运行：
$post->title = request('title');
$post->body = request('body');
$post->save();
这不会更新我的帖子.但它应该根据the Laravel docs on updating Eloquent models.为什么我的模型没有更新？
>我没有错误.
>该帖子未在db中更新.
>除了没有在数据库中更新,没有别的东西似乎奇怪.没有错误.行为正常.
> running this test to see if save succeeded的结果是真的.
> This Laravel thread没有帮助
发布模型：
class Post extends Model
{
protected $fillable = [
'type','title','body','user_id',];
....
}
邮政控制人：
public function store($id)
{
$post = Post::findOrFail($id);
// Request validation
if ($post->type == 1) {
// Post type has title
$this->validate(request(),[
'title' => 'required|min:15','body' => 'required|min:19',]);
$post->title = request('title');
$post->body = request('body');
} else {
$this->validate(request(),[
'body' => 'required|min:19',]);
$post->body = request('body');
}
$post->save();
return redirect('/');
}

运行dd($post-> save())返回true.
运行
$post->save(); $fetchedPost = Post::find($post->id); dd($fetchedPost);
向我显示$fetchedPost与之前的帖子相同而没有更新的数据.
由于Laravel 5.5 laravel已经改变了一些验证机制,我想你需要尝试这种方式.
public function store(Request $request,$id)
{
$post = Post::findOrFail($id);
$validatedData = [];
// Request validation
if ($post->type == 1) {
// Post type has title
$validatedData = $request->validate([
'title' => 'required|min:15',]);
} else {
$validatedData = $request->validate([
'body' => 'required|min:19',]);
}
$post->update($validatedData);
return redirect('/');
}
