Throughout this reference, we’ll refer to the following models, which comprise a weblog application:
class Blog(models.Model): name = models.CharField(maxlength=100) tagline = [...]
In Chapter 3, we covered the fundamentals of building dynamic Web sites with Django: setting up views and URLconfs. As we explained, a view is responsible for doing some arbitrary logic , and then returning a response. In the example, our arbitrary logic was to calculate the current date and time.
In modern Web applications, the [...]
