錯誤：運行測試時調用 null 上的成員 function store()

Question

我寫了以下測試：

public function testUserCanUploadFile()
    {
        $this->withoutExceptionHandling();
        $this->signIn();

        Storage::fake('public'); //Mock a disk
        $file = UploadedFile::fake()->image('test.jpg'); //Upload a fake image.

        $assortmentAttributes = Assortment::factory()->raw(); // Use the assortment factory.
        $assortmentAttributes['image'] = $file; // Add a additional field in the assortment factory.

        $this->post(route('assortments.store'), $assortmentAttributes)->assertRedirect(); // Post the fields to the assortmentcontroller store method. Expect a 403.
        Storage::disk('public')->assertExists($file->hashName()); // Check if the field exists.

    }

連同以下 controller：

$user = request()->user();
        $assortment = $user->assortments()->create($request->all());

        /*if ($request->hasFile('image')) {
            dd($request->file('image'));
        }*/
        
        Assortment::create([
             'file' => $request->file('file')->store('file', 'public')
         ]);
 
         if ($request->wantsJson()) {
             return response([], 204);
        }
        return back();
   
        return redirect()->route('assortments.show', $assortment->slug)
                        ->with('success','Verzameling is succesvol aangemaakt.');

        
    }

當我運行測試時，沒有文件上傳。 我剛剛收到消息： Error: Call to a member function store() on null 。 它指的是我的 controller 中的第 56 行。 這是以下行：

'file' => $request->file('file')->store('file', 'public')

我不 go 出了什么問題。 當我將此代碼添加到我的 controller 時發生此錯誤：

Assortment::create([
             'file' => $request->file('file')->store('file', 'public')
         ]);
 
         if ($request->wantsJson()) {
             return response([], 204);
        }
        return back();

在添加之前，我沒有收到錯誤消息，因為我使用了if語句：

if ($request->hasFile('image')) {
            dd($request->file('image'));
        }

我該如何解決這個錯誤？

編輯：解決了錯誤。 將file更改為image 。 現在我得到： Illuminate\Database\QueryException: SQLSTATE[23000]: Integrity constraint violation: 19 NOT NULL constraint failed: assortments.user_id (SQL: insert into "assortments" ("slug", "updated_at", "created_at") values (-1, 2020-12-17 13:11:11, 2020-12-17 13:11:11))

Answer 1

您在關鍵圖像下發送 UploadedFile

$assortmentAttributes['image'] = $file; 

您正在嘗試使用 controller 中的密鑰file檢索文件

Assortment::create([
    'file' => $request->file('file')->store('file', 'public')
]);

//Here it should be
Assortment::create([
    'file' => $request->file('image')->store('file', 'public')
]);

現在我得到： Illuminate\Database\QueryException: SQLSTATE[23000]: Integrity constraint violation: 19 NOT NULL 約束失敗: assortments.user_id (SQL: insert into "assortments" ("slug", "updated_at", "created_at") values (-1, 2020-12-17 13:11:11, 2020-12-17 13:11:11))

您可以嘗試通過關系創建分類記錄或手動添加 FK user_id的值

//Assuming User model has a relation defined for Assortment as assortment()
$user->assortment()->create([
    'file' => $request->file('image')->store('file', 'public')
]);

//OR
Assortment::create([
    'user_id' => $user->id,
    'file' => $request->file('image')->store('file', 'public')
]);
