Laravel : Integrity constraint violation

问题:

I have a SQLSTATE Integrity constraint violation error with the default register form.

I have a add a rank row to a new table. Here's my migration;

Schema::create('users', function(Blueprint $table) {     $table->increments('id');     $table->string('name');     $table->string('email')->unique();     $table->string('password', 60);     $table->string('rank');     $table->rememberToken();     $table->timestamps(); }); 

I want that the server send the value of default, so I add this to

\app\Services\Registrar.php;

public function create(array $data) {     return User::create([         'name' => $data['name'],         'email' => $data['email'],         'password' => bcrypt($data['password']),         'rank' => 'default',     ]); } 

And I have the following error;

Illuminate\Database\QueryException thrown with message "SQLSTATE[23000]: Integrity constraint violation: 19 NOT NULL constraint failed: users.rank (SQL: insert into "users" ("name", "email", "password", "updated_at", "created_at") values (Félix Desjardins, felixinx@gmail.com, y$Rp6YFZivHDqVNsQLDzGar.dEqRf9vxdSdQd/H8.xNWvVLqS0gwpDe, 2015-04-18 15:07:23, 2015-04-18 15:07:23))"  Stacktrace:

In order to protect you from mass assignment vulnerabilities, Laravel requires you to explicitly set (or exclude) values you want to be mass assignable by passing them in through the create()-method.

So if you want rank to be a mass-assignable attribute, you have to add it to the $fillable-property (which is just an array of the mass-assignable attributes) on your User-model. Any other attribute that is not on the 'whitelist' so to speak will be ignored. So on your User model you just do:

protected $fillable = [     'name',     'email',     'password',     'rank', ]; 

You have to do this for every model-class you want to be mass-assignable.

Pro-Tip: You can assign default values in your schema, so you don't have to pass them everytime you create a user:

$table->string('rank')->default('default'); 

If you don't pass a specific 'rank' while creating, it will fall back to 'default'.

Another option (which you should use with caution) is to explicitly ignore the mass assignment constraints by using forceCreate:

User::forceCreate([         'name' => $data['name'],         'email' => $data['email'],         'password' => bcrypt($data['password']),         'rank' => 'default',     ]);
