saying goes, the more hooks the better. If you find yourself copying code between multiple templates, you should consider placing the snippet in a {% block %} of the parent template. If you need to access the contents of a block in the parent template, use the {{ block.super }} tag, which will show the contents of the parent template. This variable is useful if you want to add content only to the upper block of code, not all overloads. Multiple {% block %} with the same name

extracted from the matching URL. For example: If the request URL is/time/plus/3/, then offset will be 3, if the request URL is/time/plus/21/, then offset will be 21. Note that the captured value is always a string (string) type, not an integer type, even if the string is entirely composed of numbers (for example: "21").4).

1. Accessing the foreign key (Foreign key) valueWhen you get a field for the ForeignKey , you get the relevant data model object. For example:>>> B = Book.objects.get (id=50) >>> b.publisherFor a relationship defined by ForeignKey, the other end of the relationship can be traced back in reverse, albeit slightly different because of the asymmetric relationship. From a Publisher object, get books directly, using Publisher.book_set.all (), as follows:>>> p = Publisher.objects.get (name= ' Apress pu
