Django Trick: Using get_FOO_display() for Human-Readable Choices
When you define choices for a model field in Django (such as a CharField with predefined options), Django stores the actual values in the database. However, if you want to display the human-readable labels associated with these choices in your templates or views, you can use the get_FOO_display() method. This is a lesser-known feature that provides a simple and effective way to show user-friendly labels for fields with choices.
How It Works: Django automatically provides a get_FOO_display() method for any field with choices, where FOO is the name of the field. This method returns the human-readable label associated with the field's current value.
Why It’s Cool: The get_FOO_display() method makes it easy to work with choice fields and display user-friendly labels in templates or views without needing to manually map the values to labels. This trick keeps your code clean, ensures consistency, and improves readability when presenting data to users.
