There is no strict order that you must follow when organizing your Django models, but it's best to keep them organized and readable to make it easier for other developers to understand your code. Here is one possible order that you can follow:

  1. Constants and utilities: This includes any constants and helper functions that are used in your model.

  2. Fields: Define your fields, including their types and options.

  3. Meta options: Define any metadata options for your model, such as ordering or database tables.

  4. Methods: Define any methods that are related to your model.

  5. Special model methods: Define the __str__ method for your model, which is used when the object is printed, as well as any other methods like get_absolute_url or save.

Here's an example of a model that follows this order:

class MyModel(models.Model):
    MY_CONSTANT = 'constant'

    my_field = models.CharField(max_length=50)
    my_other_field = models.IntegerField()

    class Meta:
        ordering = ['my_field']
        verbose_name = 'My Model'
        verbose_name_plural = 'My Models'

    def my_method(self):
        # some code

    def __str__(self):
        return f'{self.my_field} - {self.my_other_field}'

    def get_absolute_url(self):
        return reverse('myapp:view', args=[str(self.id)])
