Missing argument 2 for UserController::edit() - Laravel

问题

I'm using the framework Laravel.

I have 2 tables (Users and Persons). When I want to edit the user and at the same time the person, I get the error message:

Missing argument 2 for UserController::edit()

Table Users

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;

Table Persons

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;

Model Person

class Person extends Eloquent {

    protected $table = 'persons';

    protected $primaryKey = 'person_id';

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

    public $timestamps = false;
}

The UserController with edit and update

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');
    }

View Edit

<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() }}

The Route

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

What am I doing wrong?

回答1:

Your function declaration specifies two parameters:

public function edit($user_id, $person_id)

Yet the route only injects one parameter user_id.

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

It should look like this:

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

Or remove $person_id from the function declaration.
