我在Laravel非常新，這是我在Laravel的第一個項目。像往常一樣，首先我正在開發一個完整的用戶身份驗證系統。我可以註冊一個單用戶，可以發送用戶驗證郵件，點擊該鏈接後，我可以激活一個新的用戶帳戶，可以登錄，並可以註銷。但之後，當我試圖註冊另一個新用戶和點擊驗證鏈接後，我現在面臨一個例外是，Laravel SQLSTATE [23000]：完整性約束違規：1062重複條目
Illuminate \ Database \ QueryException
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '' for key 'users_code_unique' (SQL: update `users` set `code` = , `active` = 1, `updated_at` = 2014-07- 25 04:26:06 where `id` = 41)
現在這是我的route.php，
<?php
Route::get('/',array(
'as' =>'home',
'uses' =>'[email protected]'
));
Route::get('/signin',array(
'as' =>'signin',
'uses' =>'[email protected]'
));
Route::get('/signup',array(
'as' => 'signup',
'uses' => '[email protected]'
));
/*
/*
/Authenticated Group
*/
Route::group(array('before' => 'auth'),function(){
/*
/Sign Out(GET)
*/
Route::get('/signout',array
(
'as' => 'signout',
'uses' => '[email protected]'
));
});
/*
/UnAuthenticated Group
*/
Route::group(array('before' => 'guest'),function(){
/* CSRF Protect*/
Route::group(array('before' => 'csrf'),function(){
/*
/Create Account(POST)
*/
Route::post('/signup',array(
'as'=> 'signup',
'uses'=>'[email protected]'
));
/*
/Sign In(POST)
*/
Route::post('/signin',array(
'as' => 'signin-post',
'uses' => '[email protected]'
));
});
/*
/Sign In (GET)
*/
Route::get('/signin',array(
'as' => 'signin',
'uses' => '[email protected]'
));
/*
/Create Account(GET)
*/
Route::get('/signup',array(
'as' => 'signup',
'uses'=> '[email protected]'
));
Route::get('signup/account/activate/{code}',array(
'as' =>'activate-account',
'uses' =>'[email protected]'
));
});
?>
，這是我的AccountController
<?php
class AccountController extends \BaseController {
public function signinGet()
{
return View::make('account.signin');
}
public function signinPost(){
$validator = Validator::make(Input::all(),array(
'email' => 'required|email',
'password' => 'required'
));
if($validator->fails()){
//redirect to the signin page
return Redirect::route('signin')
->withErrors($validator)
->withInput();
}else{
//Attempt user singin
$auth = Auth::attempt(array
(
'email' => Input::get('email'),
'password' => Input::get('password'),
'active' => 1
));
if($auth){
//Redirect To intented URL
return Redirect::intended('/');
}
else
{
return Redirect::route('signin')
->with('global','The username or password you provided is wrong or account not activated!');
}
}
return Redirect::route('signin')
->with('global','There is a problem Signing You in.');
}
/**
* Show the form for creating a new resource.
*
* @return Response
*/
public function signupGet()
{
return View::make('account.signup');
}
public function signupPost()
{
$validator = Validator::make(Input::all(), array(
'email' => 'required|max:255|email|unique:users',
'username' => 'required|min:3|unique:users',
'password' => 'required|min:6',
'password_again' => 'required|same:password'
)
);
if($validator->fails())
{
return Redirect::route('signup')
->withErrors($validator)
->withInput();
}else
{
$email = Input::get('email');
$username = Input::get('username');
$password = Input::get('password');
//Activation Code
$code = str_random(60);
$user = User::create(array(
'email' => $email,
'username' => $username,
'password' => Hash::make($password),
'code' => $code,
'active' => 0
)
);
if($user){
//User Activation Code Creation
Mail::send('emails.auth.activate', array('link' => URL::route('activate-account',$code), 'username' => $username),function($message) use ($user)
{
$message->to($user->email,$user->username)->subject('Activate Your Account');
});
return Redirect::route('signup')
->with('global','Your Account has been created! We have sent you an email to activate your account.Please Check the both the Inbox and Spam Folder.');
}
}
//return 'This is a Post Result';
}
public function activatePost($code){
$user = User::where('code','=',$code)->where('active','=',0);
if($user->count()){
$user = $user->first();
$user->active = 1;
$user->code = '';
if($user->save()){
return Redirect::route('home')
->with('global','Activated!.You can sign in now!');
}
}
else{
return Redirect::route('signup')
->with('global','Sorry!We could not activate your acount,please try again later.');
}
}
public function signoutGet(){
Auth::logout();
return Redirect::route('home');
}
}
?>
，這是我創建的用戶遷移文件
<?php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateUsersTable extends Migration {
public function up()
{
Schema::create('users', function(Blueprint $table)
{
$table->increments('id');
$table->string('username',255)->unique();
$table->string('email',255)->unique();
$table->string('password',60);
$table->string('password_temp',60);
$table->string('code',60)->unique();
$table->integer('active');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::drop('users');
}
}
?>
，這是我user.php的
<?php
use Illuminate\Auth\UserTrait;
use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableTrait;
use Illuminate\Auth\Reminders\RemindableInterface;
class User extends Eloquent implements UserInterface, RemindableInterface {
public function getRememberToken()
{
return $this->remember_token;
}
public function setRememberToken($value)
{
$this->remember_token = $value;
}
public function getRememberTokenName()
{
return 'remember_token';
}
protected $fillable = array('email','username','password','password_temp','code','active');
use UserTrait, RemindableTrait;
/**
* The database table used by the model.
*
* @var string
*/
protected $table = 'users';
/**
* The attributes excluded from the model's JSON form.
*
* @var array
*/
protected $hidden = array('password', 'remember_token');
}
?>
現在什麼問題呢？
它看起來像'用戶> code'不是唯一的。你確定它是？試着迴應它，並與你已經在數據庫中得到的結果進行比較。我在winXP上用str_random遇到了一個問題 - 在短時間內它生成了相同的隨機字符串... – Tom
對不起，對我來說，它不是laravels 4'str_random'，而是一些其他函數來隨機化，但它產生和我說的一樣。 – Tom
那麼如何解決這個問題，你有什麼解決辦法嗎？ – Tanveer
