Как настраивать Django каждый раз, когда вы его используете? (т.е. используя ** исходный бункер / активировать ** и ** python сервер запуска manage.py **)

Я новичок с Django, и меня очень смущает, как последовательно настраивать Django каждый раз, когда вы открываете новый терминал. Каждый раз, когда я это делаю, мне приходится всегда перезапускать и делать следующее:

  1. Сменить каталог (cd) на мой try django каталог, с которого я начинаю виртуальная среда (source bin/activate)

  2. После того, как на терминале появится автомат c (trydjango) в крайнем левом углу от (trydjango) ismodes-MacBook-Air:trydjango ismodes$, я знаю, что у меня включена виртуальная среда.

  3. Затем я go в каталог sr c через терминал, где я ввожу python manage.py runserver

У меня возникают постоянные ошибки (например, AttributeError) всякий раз, когда я вхожу на шаг runserver (шаг 3). Я что-то делаю не так?

Ниже приведен полный Traceback ошибки 

(trydjango) ismodes-MacBook-Air:src ismodes$ python manage.py runserver

Трудно сказать, с каких именно шагов следует начать проект.

  1. django-admin startproject new_project_name Создать новый проект

  2. manage.py runserver IP:Port Запускать сервер при запуске, http://127.0.0.1: 8000 / или http://localhost: 8000 /

  3. manage.py startapp new_APP_name в new_project_name для создания нового приложения

  4. manage.py makemigrations в new_project_name, чтобы сообщить django проект изменен, затем создать файл миграции.

  5. manage.py migrate в new_project_name для обновления.

  6. в new_project_name / new_project_name / settings.py INSTALLED_APPS добавьте элемент с new_APP_name.apps.new Appconfig subclass name в new_APP_name \ apps.py

  7. в new_project_name / new_project_name / urls.py добавьте парсер URL, например 

    from . import views

urlpatterns = [
    path('', views.Topic, name='index')
]

  8. в модели реестра new_project_name / new_APP_name / admin.py, например, 

    from .models import Topic

admin.site.register(Topic)
