Laravel-UserController：：EDIT()的参数2缺失

Laravel - Missing argument 2 for UserController::edit()(Laravel-UserController：：EDIT()的参数2缺失)

问题描述

我正在使用框架Laravel。

我有两个表(用户和人员)。当我想同时编辑用户和人员时，我收到错误消息：

UserController：：EDIT()缺少参数2

表用户

CREATE TABLE IF NOT EXISTS `festival_aid`.`users` (
  `user_id` BIGINT NOT NULL AUTO_INCREMENT,
  `user_username` VARCHAR(45) NOT NULL,
  `user_email` VARCHAR(45) NOT NULL,
  `user_password` CHAR(32) NOT NULL,
  `user_salt` CHAR(32) NOT NULL,
  `user_created` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `user_modified` TIMESTAMP NULL,
  `user_deleted` TIMESTAMP NULL,
  `user_lastlogin` TIMESTAMP NULL,
  `user_locked` TIMESTAMP NULL,
  `user_token` VARCHAR(128) NULL,
  `user_confirmed` TIMESTAMP NULL,
  PRIMARY KEY (`user_id`, `person_id`),
  UNIQUE INDEX `user_email_UNIQUE` (`user_email` ASC),
  INDEX `fk_users_persons1_idx` (`person_id` ASC),
  CONSTRAINT `fk_users_persons1`
    FOREIGN KEY (`person_id`)
    REFERENCES `festival_aid`.`persons` (`person_id`)
    ON DELETE CASCADE
    ON UPDATE NO ACTION)
ENGINE = InnoDB;

表人员

CREATE TABLE IF NOT EXISTS `festival_aid`.`persons` (
  `person_id` BIGINT NOT NULL AUTO_INCREMENT,
  `person_firstname` VARCHAR(45) NULL,
  `person_surname` VARCHAR(45) NULL,
  `person_created` TIMESTAMP NOT NULL,
  `person_modified` TIMESTAMP NULL,
  `person_deleted` TIMESTAMP NULL,
  PRIMARY KEY (`person_id`))
ENGINE = InnoDB;

模特

class Person extends Eloquent {

    protected $table = 'persons';

    protected $primaryKey = 'person_id';

    public function person()
    {
        return $this->belongsTo('User');
    }

    public $timestamps = false;
}

具有编辑和更新功能的用户控制器

public function edit($user_id, $person_id)
{
    $user = User::find($user_id);
    $person = Person::find($person_id);

    return View::make('users.edit')
        ->with('user', $user)
        ->with('person', $person);
}

public function update($user_id, $person_id)
{
    $rules = array(
        'person_firstname' => 'required',
        'person_lastname' => 'required',
        'user_username' => 'required|unique:users',
        'user_email' => 'required|unique:users|email',
    );
    $validator = Validator::make(Input::all(), $rules);

    if ($validator->fails()) {
        Redirect::to('users/' . $user_id . '/' . $person_id . '/edit')
            ->withErrors($validator)
            ->withInput(Input::except('user_password'));
    } else {
        $user = User::find($user_id);
        $person = Person::find($person_id);

        $person->person_firstname = Input::get('person_firstname');
        $person->person_lastname = Input::get('person_lastname');
        $user->user_username = Input::get('user_username');
        $user->user_email = Input::get('user_email');

        $user->save();
        $person->save();

        Session::flash('message', 'Successfully updated user!');
        return Redirect::to('users/index');
    }

查看编辑

<legend>Edit {{ $person->person_firstname }}</legend>

{{ HTML::ul($errors->all()) }}

    {{ Form::model($user, $person, array('method' => 'PUT')) }}

    <div class="form-group">
        {{ Form::label('firstname', 'Firstname') }}
        {{ Form::text('person_firstname', Input::old('firstname'), array('class'=>'form-control', 'placeholder' => 'Firstname')) }}
    </div>

    <div class="form-group">
        {{ Form::label('surname', 'Surname') }}
        {{ Form::text('person_surname', Input::old('surname'), array('class'=>'form-control', 'placeholder' => 'Surname')) }}
    </div>

    <div class="form-group">
        {{ Form::label('username', 'Username') }}
        {{ Form::text('user_username', Input::old('username'), array('class'=>'form-control', 'placeholder' => 'Username')) }}
    </div>

    <div class="form-group">
        {{ Form::label('email', 'Email') }}
        {{ Form::text('user_email', Input::old('email'), array('class' => 'form-control')) }}
    </div>

    <div class="form-group">
        {{ Form::label('Password') }}
        {{ Form::password('user_password', array('class'=>'form-control', 'placeholder' => 'Password')) }}
    </div>

    {{ Form::submit('Edit the User!', array('class' => 'btn btn-primary')) }}

    {{ Form::close() }}

路线

Route::get('/users/{user_id}/edit', 'UserController@edit');

我做错了什么？

推荐答案

您的函数声明指定了两个参数：

public function edit($user_id, $person_id)

然而，该路由仅注入一个参数user_id。

Route::get('/users/{user_id}/edit', 'UserController@edit');

它应该是这样的：

Route::get('/users/{user_id}/{person_id}/edit', 'UserController@edit');

或从函数声明中删除$person_id。
