Django actually uses two separate options to handle required and nonrequired fields on models: blank and null. The blank option affects only forms displayed to users of a Django-powered application and prevents the form from displaying a validation error if no value is entered. The null option, on the other hand, will set up the database to accept a NULL value. If you need to allow users to leave a field blank and have a NULL inserted into its column in the database, you ll need to specify both options. If this seems strange, keep in mind that there are very common cases where you ll want to allow a user to leave a field blank in a form (or even hide a field entirely) but still prevent a NULL value from going to the database (by generating a value for that field if the user doesn t supply one). You ll see an example later in this chapter. Also, it s important to note that for text-based field types (CharField, TextField, and others), Django will never insert a NULL. For these field types, a blank value will be inserted as an empty string. This is to avoid a situation where there are potentially two different blank values for the field (either an empty string or a NULL) and to ensure that code that checks for blank values can be kept simple. Because of this, you should generally avoid specifying null=True on text-based field types.

I have covered an enormous amount of ground here (although I have also left out a lot). You should not feel daunted by the sheer volume of code in this chapter. Patterns are meant to be used in the right circumstances and combined when useful. Use those described in this chapter that you feel meet the needs of your project, and do not feel that you must build an entire framework before embarking on a project. On the other hand, there is enough material here to form the basis of a framework, or just as likely, to provide some insight into the architecture of some of the prebuilt frameworks you might choose to deploy. And there s more! I left you teetering on the edge of persistence, with just a few tantalizing hints about collections and mappers to tease you. In the next chapter, I will look at some patterns for working with databases and for insulating your objects from the details of data storage.

With the Delete permission, a user can delete existing categories and subcategories. Over time, some discussion threads will become stale or will have only historical importance. Deleting categories containing those threads will improve the forum experience for new readers, who might not be interested in viewing those threads.

ost web applications of any complexity handle persistence to a greater or lesser extent. Shops must recall their products and their customer records. Games must remember their players and the state of play. Social networking sites must keep track of your 238 friends and your unaccountable liking for boy-bands of the 80s and 90s. Whatever the application, the chances are it s keeping score behind the scenes. In this chapter, I look at some patterns that can help. This chapter will cover The Data Layer interface: Patterns that define the points of contact between the storage layer and the rest of the system Object watching: Keeping track of objects, avoiding duplicates, automating save and insert operations Flexible queries: Allowing your client coders to construct queries without thinking about the underlying database Creating lists of found objects: Building iterable collections Managing your database components: The welcome return of the Abstract Factory pattern

Just as you added a slug for categories, it s a good idea to add one for entries and to set it up to populate a default from the entry s title. So add the following to the Entry model: slug = models.SlugField() Then change the EntryAdmin class to automatically populate the slug: class EntryAdmin(admin.ModelAdmin): prepopulated_fields = { 'slug': ['title'] } With the Category model, you added unique=True to force the slug to be unique, but for entries it would be nice to have something slightly different. Most good weblog software builds URLs that include the publication dates of entries (so that they look like /2007/10/09/ entry-title/), which means that all you really need is for the combination of the slug and the publication date to be unique. Django provides an easy way to specify this, through an option called unique_for_date: slug = models.SlugField(unique_for_date='pub_date')

The Move Thread permission allows a user to move a discussion thread from one category to another. This again helps organize threads into logical units. I ll discuss how to move a thread in the more detailed Moving Threads section later in this chapter.
