Laravel 更新唯一列

Question

我在下面有更新功能，但它返回此错误：Illuminate\Database\QueryException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'name1' in 'where clause' (SQL: select count(*) as aggregate from `groups` where `name1` = postman group)问题： ID added to column name: Unknown column 'name1'，我看不到发生这种情况的地方。代码public function update(Request $request, $id){    $user = $request->user();    $group = Group::findOrFail($id);    $isAdmin = $user->groupsAdmin()->whereName($group->name)->exists();    if($isAdmin) {        $rules = [            'name' => 'required|string|max:255|unique:groups,name' . $id,            'description' => 'nullable|string|max:255',        ];        if ($request->hasFile('photo')) {            $rules['photo'] = 'mimetypes:image/jpeg,image/png|max:2048';        }        $this->validate($request, $rules);        $group->name = $request->input('name');        $group->description = $request->input('description');        if ($request->hasFile('photo')) {            $photo = $request->file('photo');            $filename = 'Group' . '-' . time() . '.' . $photo->getClientOriginalExtension();            $location = public_path('images');            $request->file('photo')->move($location, $filename);            $oldFilename = $group->photo;            $group->photo = $filename;            if(!empty($group->photo)){                Storage::delete($oldFilename);            }        }        $group->save();        return response()->json([            'data' => new GroupResource($group),            'message' => 'Your group updated successfully.'        ]);    } else {        return response()->json([            'data' => null,            'message' => 'Only admins can edit group details.'        ]);    }}任何想法？

你需要在 the 后面加一个逗号，groups,name因为 unique 规则是这样写的unique:table,column,except,idColumn
