hello
Here is a class from django framework
from django.db import models
class Article(models.Model):
titre = models.CharField(max_length=100)
auteur = models.CharField(max_length=42)
contenu = models.TextField(null=True)
date = models.DateTimeField(auto_now_add=True, auto_now=False,
verbose_name="Date de parution")
def __str__(self):
return self.titre
From a Python point of view, what are titre, auteur, contenu and date ?
Are they class attributes, so common to all instance of Article ?
It seems so to me.
But if i do in a django shell (run with py manage.py shell)
Article.titre
it doesnt work,
AttributeError: type object 'Article' has no attribute 'titre'
why ?
if I test on a small class
class MyClass:
i=0
MyClass.i
0
works
When we create an object of class Article
article = Article(titre="Bonjour", auteur="Maxime")
article.contenu = "Les crêpes bretonnes sont trop bonnes !"
we use the same names titre, auteur, contenu, which should be instance
attribute this time. This is confusing to me
thx
