Make objects readable and set table behavior.
str and the Meta Class is a free Django Academy lesson on CoddyKit — lesson 4 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Django Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Make Objects Readable
Out of the box, a model object prints as a vague Object 1. You can fix that and also shape table behavior cleanly.
Define __str__
Add a __str__ method to return a friendly label. Now your object shows its title instead of a useless number.
class Book(models.Model):
title = models.CharField(max_length=200)
def __str__(self):
return self.titleWhere __str__ Shows Up
That __str__ label appears in the admin, the shell, and templates, making every object instantly recognizable. 👀
Always Return a String
Your __str__ must return a string. If a field might be a number, wrap it with str() before returning it.
def __str__(self):
return str(self.year)Meet the Meta Class
An inner Meta class holds options about the model as a whole, separate from its fields. It tunes how the table behaves.
class Book(models.Model):
class Meta:
ordering = ["title"]ordering Sets Default Sort
The ordering Meta option sets how query results sort by default, so lists come back in a predictable order.
class Meta:
ordering = ["-created"]Friendly Names with verbose_name
Use verbose_name and verbose_name_plural in Meta to control the labels Django shows in the admin interface.
class Meta:
verbose_name_plural = "Books"Custom Table Name
Override the generated table name with db_table in Meta when you need to match an existing or legacy database.
class Meta:
db_table = "catalog_books"Cross-Field Uniqueness
The unique_together Meta option requires a combination of fields to be unique, like one slug per author.
class Meta:
unique_together = ["author", "slug"]Meta Describes the Model
Think of Meta as settings for the whole model, while fields and __str__ describe its data and display.
Both Are Optional but Worth It
You can skip __str__ and Meta, but adding them makes your models far nicer to work with day to day.

Recap: __str__ and Meta
You learned that __str__ gives objects a readable name and the Meta class tunes model-wide behavior like ordering and names. Polished models! 🎉
