AttributeError: 'Article' object has no attribute 'title'

Answer 1

You are defined your model with colon (:) intead of equal to (=) symbol. So Your model should be as,
class Article(models.Model):
title = models.CharField(max_length=100)
slug = models.SlugField()
body = models.TextField()
date = models.DateTimeField(auto_now_add=True)
# ADD IN THUMNAILL LETTER
def __str__(self):
return self.title
Here is the image reference,
Update-1
In [2]: # METHOD -- 1
In [3]: article_1 = Article()
In [4]: article_1.title = "my title 1"
In [5]: article_1.save()
In [6]: Article.objects.all()
Out[6]: <QuerySet [<Article: my title 1>]>
In [7]: # METHOD -- 2
In [8]: article_2 = Article.objects.create(title="my title 2")
In [9]: Article.objects.all()
Out[9]: <QuerySet [<Article: my title 1>, <Article: my title 2>]>
