我试图在Laravel 4中的数据库播种期间关联相关模型.根据这里的文档,我可以这样做:

$user->roles()->attach(1);

所以,在我正在运行的数据库种子中:

$package = Package::create([
    'name' => $faker->word,
    'summary' => $faker->sentence,
    'base_price' => $faker->randomFloat(2, 200, 10000)
]);

// Attach 1-5 randomly selected items to this package
foreach(range(1, 5) as $index)
{
    $randomItem = Item::orderBy(DB::raw('RAND()'))->first();
    $package->items()->attach($randomItem->id);
}

包装物品此时已经播种,并且种子没有问题.上面的代码从Artisan给出了这个:

[BadMethodCallException]                                              
Call to undefined method Illuminate\Database\Query\Builder::attach()

这里的某个人似乎认为该attach()方法实际上并不存在且文档错误,但我发现很难相信.

TL; DR在Eloquent中创建多对多关系的正确方法是什么？

我在使用Laravel的Input::replace()方法在单元测试期间模拟POST请求时遇到了一些麻烦.

根据Jeffrey Way 这里和这里的说法,你可以这样做:

# app/tests/controllers/PostsControllerTest.php

public function testStore()
{
    Input::replace($input = ['title' => 'My Title']);</p>

    $this->mock
         ->shouldReceive('create')
         ->once()
         ->with($input);

    $this->app->instance('Post', $this->mock);

    $this->call('POST', 'posts');

    $this->assertRedirectedToRoute('posts.index');
}

但是,我不能让这个工作.Input::all()并且所有Input::get()调用仍然返回一个空数组或Input::replace()使用后返回null .

这是我的测试功能:

public function test_invalid_login()
{
    // Make login attempt with invalid credentials
    Input::replace($input = [
        'email'     => 'bad@email.com',
        'password'  => 'badpassword',
        'remember'  => true
    ]);

    $this->mock->shouldReceive('logAttempt')
    ->once()
    ->with($input)
    ->andReturn(false);

    $this->action('POST', 'SessionsController@postLogin');

    // Should redirect back to login form with old input …

我试图在单元测试中模拟Laravel的一些外观,但似乎测试总是通过无论如何.

例如,此示例取自Laravel文档:

Event::shouldReceive('fire')->once()->with('foo', array('name' => 'Dayle'));

看起来我可以把它放在任何一种测试方法中,即使在Event外观上没有做过任何类型的测试,它们总是会通过.

这是测试类:

class SessionsControllerTest
extends TestCase
{    
    public function test_invalid_login_returns_to_login_page()
    {
        // All of these pass even when they should fail
        Notification::shouldReceive('error')->once()->with('Incorrect email or password.');
        Event::shouldReceive('fire')->once()->with('foo', array('name' => 'Dayle'));
        Notification::shouldReceive('nonsense')->once()->with('nonsense');

        // Make login attempt with bad credentials
        $this->post(action('SessionsController@postLogin'), [
            'inputEmail'     => 'bademail@example.com',
            'inputPassword'  => 'badpassword'
        ]);

        // Should redirect back to login form with old input
        $this->assertHasOldInput();
        $this->assertRedirectedToAction('SessionsController@getLogin');
    }

}

我为了测试外墙而缺少什么？我是否正确地认为我应该可以shouldReceive()在没有任何设置的情况下调用任何Laravel Facade？
