Wondering how I should go about this task. Task 2...

articles/models.py 
from django.db import models


class Article(models.Model):
    headline = models.CharField(max_length=255)
    publish_date = models.DateTimeField()
    content = models.TextField()
    writer = models.ForeignKey('Writer')
    class Meta:
        abstract = True

    def __str__(self):
        return self.headline


class Writer(models.Model):
    name = models.CharField(max_length=255)
    email = models.EmailField()
    bio = models.TextField()

    def __str__(self):
        return self.name

Here are the steps broken down:

  • Now make a new model, Review, ...

use class to declare the model

  • ...that inherits from Article.

use Article as the parent class

  • It should have one new field, rating, which is an IntegerField with a default value of 5.

this has the same format as the other fields, but with parameter default set to 5

Post back if you need more help. Good luck!!!
