Laravel 表单验证请求唯一无知对更新不起作用

Question

I'm trying to update a data which has a unique name required on validation. However, I can't get it to work because it keep telling me that The name has already been taken. . Already tried the

Please have a look at my validation script:

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class RequestDepartment extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'division_id' => 'required|numeric',
            'name' => "sometimes|required|string|unique:departments,name,{$this->id},id",
            'description' => 'sometimes|nullable|string'
        ];
    }
}

also, my controller's update script:

/**
 * Update the specified resource in storage.
 *
 * @param  \App\Http\Requests\RequestDepartment  $request
 * @param  \App\Department  $department
 * @return \Illuminate\Http\Response
 */
public function update(RequestDepartment $request, Department $department)
{
    $department->update($request->validated());
    $department = Department::whereId($department->id)->with('division')->first();

    return response()->json([
        'updated' => true,
        'data' => $department,
    ]);
}

I'm using Laravel 7.x, any idea please?

EDIT

I want to update the division_id or description field.

EDIT 2

My form is dynamic, inside Vue instance and Form class

data() {
  return {
    form: new Form({
      division_id: "",
      company_id: "",
      name: "",
      description: ""
    }),
    updateForm: new Form({
      division_id: "",
      company_id: "",
      name: "",
      description: ""
    }),
    filter: ""
  };
},

Answer 1

Try This,

'name' => "required|string|unique:departments,name,". $id,

Here $id means wchich id you want to update. this will check unique portion all name data but not for this id.
