django-unordered-body-content-in-model (DJ012)

Derived from the flake8-django linter.

What it does

Checks for the order of Model's inner classes, methods, and fields as per the Django Style Guide.

Why is this bad?

The Django Style Guide specifies that the order of Model inner classes, attributes and methods should be as follows:

1. All database fields
2. Custom manager attributes
3. class Meta
4. def __str__()
5. def save()
6. def get_absolute_url()
7. Any custom methods

Examples

from django.db import models


class StrBeforeFieldModel(models.Model):
    class Meta:
        verbose_name = "test"
        verbose_name_plural = "tests"

    def __str__(self):
        return "foobar"

    first_name = models.CharField(max_length=32)
    last_name = models.CharField(max_length=40)

Use instead:

from django.db import models


class StrBeforeFieldModel(models.Model):
    first_name = models.CharField(max_length=32)
    last_name = models.CharField(max_length=40)

    class Meta:
        verbose_name = "test"
        verbose_name_plural = "tests"

    def __str__(self):
        return "foobar"
