[英]How to setup Django every time you use it? (i.e. using **source bin/activate** and ** python manage.py runserver**)
I am a beginner with Django, and I am very confused as to how to consistently setup Django everytime you are opening a new terminal.我是 Django 的初学者,对于每次打开新终端时如何始终如一地设置 Django,我感到非常困惑。 Whenever I do so, I have to always restart and do the following:
每当我这样做时,我必须始终重新启动并执行以下操作:
Change directory ( cd
) to my trydjango directory where I start the virtual environment ( source bin/activate
)将目录 (
cd
) 更改为我启动虚拟环境 ( source bin/activate
) 的trydjango目录
After the terminal has the automatic (trydjango)
at the furthest left of (trydjango) lyons-MacBook-Air:trydjango lyons$
I know that I have the virtual environment enabled.在终端在 (trydjango)
(trydjango) lyons-MacBook-Air:trydjango lyons$
最左边的自动(trydjango)
之后,我知道我启用了虚拟环境。
Then, I go to the src directory through the terminal where I enter python manage.py runserver
然后,我通过终端go到src目录,在里面我输入
python manage.py runserver
I am running into consistent errors (eg AttributeError) whenever I enter the runserver
step (step 3).每当我进入
runserver
步骤(步骤 3)时,我都会遇到一致的错误(例如 AttributeError)。 Am I doing something wrong?难道我做错了什么?
The following is the full Traceback of the error以下是错误的完整Traceback

The `urlpatterns` list routes URLs to views. For more information please see:

Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: path('', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))

It's not easy to tell you what exact steps to start a project.告诉您启动项目的确切步骤并不容易。
django-admin startproject new_project_name
Create a new project django-admin startproject new_project_name
创建一个新项目
manage.py runserver IP:Port
Run server when start, http://127.0.0.1:8000/ , or http://localhost:8000/ manage.py runserver IP:Port
启动时运行服务器, http://127.0.0.1:8000/或http://localhost:
manage.py startapp new_APP_name
in new_project_name to create a new APP manage.py startapp new_APP_name
in new_project_name 新建APP
manage.py makemigrations
in new_project_name to tell django project changed, then build a migration file. manage.py makemigrations
in new_project_name 告诉 django 项目发生变化,然后构建迁移文件。
manage.py migrate
in new_project_name to update. manage.py migrate
以进行更新。
in new_project_name/new_project_name/settings.py INSTALLED_APPS
add item with new_APP_name.apps.new Appconfig subclass name
in new_APP_name\apps.py在 new_project_name/new_project_name/settings.py
INSTALLED_APPS
中添加带有new_APP_name.apps.new Appconfig subclass name
的项目 new_APP_name\apps.py
in new_project_name/new_project_name/urls.py add you URL parser, for example在 new_project_name/new_project_name/urls.py 添加你 URL 解析器,例如
from. import views urlpatterns = [ path('', views.Topic, name='index') ]
in new_project_name/new_APP_name/admin.py register model for example,在 new_project_name/new_APP_name/admin.py 注册 model 例如,
from.models import Topic admin.site.register(Topic)
