Valueerror: zu viele Werte in Django Modelle

Question

Test.py

Die Dateien entpacken dient alles innerhalb der memepost App zu testen.

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

Diese Datei dient zur Erstellung von Memen in meiner Datenbank-Schema zu sein.

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"] 

Fehler

Okay, also diese Warnung erhalte ich, aber ich denke, das Problem etwas mit dem Titel Paramater zu tun hat, da ich eine get-Funktion durch den Titel nennen. Ich hoffe ich war klar.

Sie bieten nicht Keyword-Argument für get Manager Methode

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