Database design 在透视表laravel 4中为复合键设定种子

我在我的laravel 4项目中使用了。我有一个用户和特权表以及一个数据透视表

user\u privilage

。我使用了

generate:seed

为用户和特权表设置种子，但我不知道如何为

user\u privilage

表设置种子。我试图建立一个网站，我想种子基本项目的表，以查看网站如何工作。怎么做？

我解决了这个问题。我使用以下方法创建了一个数据透视表

role\u user

seed：

php artisan generate:seed role user

在

RoleUserTableSeeder

I中输入：

$adminRole = Role::where('name','=','Admin')->first()->id;
$userRole = Role::where('name','=','Registred user')->first()->id;
$admin = User::where('username','=','admin')->first()->id;
$user = User::where('username','=','user')->first()->id;
$role_user = array(
    array('role_id' => $adminRole, 'user_id'=>$admin, 'active'=>1, 'created_at' => new DateTime, 'updated_at' => new DateTime,),
    array('role_id' => $userRole, 'user_id'=>$user, 'active'=>1, 'created_at' => new DateTime, 'updated_at' => new DateTime,)
);

// Uncomment the below to run the seeder
DB::table('role_user')->insert($role_user);

而且

db:seed

工作得很好。

);

和

db:seed

工作得很好。

首先，我为privileges表创建了一个seed程序

专用播种机

Privilege::create([
    'id'   => '1',
    'privilege' => 'privilege 1'
]);

Privilege::create([
    'id'   => '2',
    'privilege' => 'privilege 2'
]);

Privilege::create([
    'id'   => '3',
    'privilege' => 'privilege 3'
]);

Privilege::create([
    'id'   => '4',
    'privilege' => 'privilege 4'
]);

Privilege::create([
    'id'   => '5',
    'privilege' => 'privilege 5'
]);

Privilege::create([
    'id'   => '6',
    'privilege' => 'privilege 6'
]);

// Attach all privileges to admin 
$user = new User;
$user->email = 'admin@admin.com';
$user->password   = 'pass';
$user->save();

$user->privileges()->attach(array(1,2,3,4,5,6));

// Attach privileges 1 & 3 to 2nd user
$user = new User;
$user->email = 'account2@user.com';
$user->password = 'pass';
$user->save();

$user->privileges()->attach(array(1,3));

然后，我将为用户表和数据透视表设置种子

UsersTableSeeder

Privilege::create([
    'id'   => '1',
    'privilege' => 'privilege 1'
]);

Privilege::create([
    'id'   => '2',
    'privilege' => 'privilege 2'
]);

Privilege::create([
    'id'   => '3',
    'privilege' => 'privilege 3'
]);

Privilege::create([
    'id'   => '4',
    'privilege' => 'privilege 4'
]);

Privilege::create([
    'id'   => '5',
    'privilege' => 'privilege 5'
]);

Privilege::create([
    'id'   => '6',
    'privilege' => 'privilege 6'
]);

// Attach all privileges to admin 
$user = new User;
$user->email = 'admin@admin.com';
$user->password   = 'pass';
$user->save();

$user->privileges()->attach(array(1,2,3,4,5,6));

// Attach privileges 1 & 3 to 2nd user
$user = new User;
$user->email = 'account2@user.com';
$user->password = 'pass';
$user->save();

$user->privileges()->attach(array(1,3));

然后在DatabaseSeeder.php上

 $this->call('PrivilegesTableSeeder');

 $this->call('UsersTableSeeder');

首先，我为privileges表创建一个播种器

专用播种机

Privilege::create([
    'id'   => '1',
    'privilege' => 'privilege 1'
]);

Privilege::create([
    'id'   => '2',
    'privilege' => 'privilege 2'
]);

Privilege::create([
    'id'   => '3',
    'privilege' => 'privilege 3'
]);

Privilege::create([
    'id'   => '4',
    'privilege' => 'privilege 4'
]);

Privilege::create([
    'id'   => '5',
    'privilege' => 'privilege 5'
]);

Privilege::create([
    'id'   => '6',
    'privilege' => 'privilege 6'
]);

// Attach all privileges to admin 
$user = new User;
$user->email = 'admin@admin.com';
$user->password   = 'pass';
$user->save();

$user->privileges()->attach(array(1,2,3,4,5,6));

// Attach privileges 1 & 3 to 2nd user
$user = new User;
$user->email = 'account2@user.com';
$user->password = 'pass';
$user->save();

$user->privileges()->attach(array(1,3));

然后，我将为用户表和数据透视表设置种子

UsersTableSeeder

Privilege::create([
    'id'   => '1',
    'privilege' => 'privilege 1'
]);

Privilege::create([
    'id'   => '2',
    'privilege' => 'privilege 2'
]);

Privilege::create([
    'id'   => '3',
    'privilege' => 'privilege 3'
]);

Privilege::create([
    'id'   => '4',
    'privilege' => 'privilege 4'
]);

Privilege::create([
    'id'   => '5',
    'privilege' => 'privilege 5'
]);

Privilege::create([
    'id'   => '6',
    'privilege' => 'privilege 6'
]);

// Attach all privileges to admin 
$user = new User;
$user->email = 'admin@admin.com';
$user->password   = 'pass';
$user->save();

$user->privileges()->attach(array(1,2,3,4,5,6));

// Attach privileges 1 & 3 to 2nd user
$user = new User;
$user->email = 'account2@user.com';
$user->password = 'pass';
$user->save();

$user->privileges()->attach(array(1,3));

然后在DatabaseSeeder.php上

 $this->call('PrivilegesTableSeeder');

 $this->call('UsersTableSeeder');
