Laravel

Question

第一次写测试所以写了一个update方法不知道哪里做错了如果有更好的测试方法请告诉我，在此先感谢

路线

Route::group(['prefix' => 'categories' , 'namespace' => 'App\Http\Controllers\Admin'] , function () {
    Route::post('create', 'CategoryController@store')->name('category.store');
    Route::put('update/{category}', 'CategoryController@update')->name('category.update');
});

这是我的控制器

控制器

public function update(Request $request , Category $category)
{
    $category->update($request->all());
}

测试

/** @test */
public function a_category_can_be_updated()
{
    $this->withoutExceptionHandling();
    $this->post(
        route('category.store'),
        [
            'name' => 'Food',
            'slug' => 'food-and-drinks',
        ],
    );

    $category = Category::first();
    $this->put(
        route('category.update', $category->id),
        [
            'name' => 'Food and',
        ],
    );
    // dd($category);

    $this->assertEquals('Food and', $category->name);
    $this->assertEquals('Food-and', $category->slug);
}

错误来自测试

  • Tests\Feature\CategoriesTest > a category can be updated
  Failed asserting that two strings are equal.

型号

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
use Illuminate\Support\Str;

class Category extends Model
{

    protected $table = 'categories';
    public $timestamps = true;

    use SoftDeletes;

    protected $dates = ['deleted_at'];
    protected $fillable = array('name', 'slug', 'parent_id');

    public function posts()
    {
        return $this->belongsToMany('App\Models\Post');
    }


    //slugging the Category-name
    public function setSlugAttribute($value)
    {
        $this->attributes['slug'] = Str::slug($this->attributes['name']);
    }

    public function scopeParent()
    {
         return Category::whereNull('parent_id');
    }

}

让我知道代码是怎么回事，提前致谢

Answer 1

做这个请求时，

$this->put(
    route('category.update', $category->id),
    [
        'name' => 'Food and',
    ],
);

您仅使用此请求更新 Category 的名称，因此在此之后，$category->slug 仍将等于 food。

您的模型中没有任何内容表明 slug 会自动更新。

此外，由于更新不是通过 $category 变量完成的，因此您需要在 $category->fresh();

的放置请求后刷新其数据

Answer 2

如“IGP”所述，您必须在执行更新后使用 $category->fresh()。但是将其分配给您的$category，如下所示：$category = $category->fresh();
