とValueError：Djangoのモデルで解凍するためにあまりにも多くの値

Question

Test.py

ファイルがmemepostアプリ内のすべてのものをテストするのに役立ちます。

from django.test import TestCase 
from memepost.models import memepost, memepostForm 
from datetime import date 
import logging 

logging.basicConfig(level=logging.INFO) 
logger = logging.getLogger(__name__) 

class memepostTestCase(TestCase): 
    def setUp(self): 
     memepost.objects.create(title="foo", 
      model_pic="/site_media/media/pic_folder/casual_headshot.jpg", 
      date=date(2017, 05, 14)) 
     memepost.objects.create(title="bar", 
      date=date(2017,05, 1)) 

    def test_memepost_enters_database(self): 
     foo = memepost.objects.get("foo") 
     bar = memepost.objects.get("bar") 
     self.assertEqual(foo.date, "6/15/17") 
     logger.debug("foo date is equal to %s", foo.date) 
     self.assertEqual(bar.model_pic, "no-img.jpg") 
     logger.debug("bar is equal to %s", bar.model_pic) 

models.py

このファイルには、私のデータベースにミームを作成するための仕組みであることがあります。

from __future__ import unicode_literals 
from django.forms import ModelForm 
from django.db import models 

# Create your models here. 
class memepost(models.Model): 
    title = models.CharField(max_length=140) 
    model_pic = models.ImageField(upload_to='pic_folder/', default='pic_folder/no-img.jpg') 
    date = models.DateTimeField() 

    def __unicode__(self): 
     return self.title 

class memepostForm(ModelForm): 
    class Meta: 
     model = memepost 
     fields = ["title", "model_pic", "date"] 

エラー

わかりましたので、私はこの警告を取得していますが、私は、問題は、私はタイトルでget関数を呼び出すので、タイトルのparamaterとは何かを持っていると思います。私は明らかに希望します。

あなたはgetマネージャーメソッドのキーワード引数を提供していない

def test_memepost_enters_database(self): 
    foo = memepost.objects.get(title="foo") 
    bar = memepost.objects.get(title="bar") 
    ...
