Шаг 1: отредактируйте соответствующие имена полей в models.py

class Bar(models.Model):
    name = models.CharField(unique=True, max_length=32)
    description = models.TextField(null=True, blank=True)


class AnotherModel(models.Model):
    bar = models.ForeignKey(Bar)  # <-- changed field name
    is_awesome = models.BooleanField()

Изменить имя поля в модели (но запомнить старое имя для 3 шага!)
Создать пустую миграцию

$ python manage.py makemigrations --empty myApp

Отредактировать новый файл пустой миграции он находится в папке миграции в папке вашего приложения и будет последней миграцией) добавив:

operations = [
        migrations.RenameField('MyModel', 'old_field_name', 'new_field_name'),
 ]

Enable mod_headers

a2enmod headers
systemctl restart apache2

put .htaccess to public_html

DirectoryIndex godot.tools.html

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

Generate ssh key pairs for accounts and add them to GitHub accounts.

	Your understanding is mostly correct. You use select_related when the object that you're going to be selecting is a single object, so OneToOneField or a ForeignKey. You use prefetch_related when you're going to get a "set" of things, so ManyToManyFields as you stated or reverse ForeignKeys. Just to clarify what I mean by "reverse ForeignKeys" here's an example:

	class ModelA(models.Model):
	pass

	class ModelB(models.Model):
	a = ForeignKey(ModelA)

	ModelB.objects.select_related('a').all() # Forward ForeignKey relationship
