Question

So I am following Jacob Kaplan-Moss’ beginning Django tutorial and he asks to implement the following in models.py

from django.db import models

class Package(models.Model):
    name        = models.CharField(max_length=300)
    version     = models.CharField(max_length=300,
                               blank=True)
    home_page   = models.URLField(blank=True)
    summary     = models.TextField()
    description = models.TextField(blank=True)
    keyboards   = models.TextField(blank=True)
    categories  = models.ManyToManyField(Category,
                             related_name="packages")

However when I run manage.py validate, it points out that “Category” is not recognized. I just don’t know what does he intend it to be.

Answer 1

Category should be another class. For example

class Category(models.Model):
    name = models.CharField(max_length=300)
