==建立新專案==
<code>django-admin startproject [網站目錄名]</code>
==跑伺服器==
<code>cd [網站目錄名]; ./manage.py runserver [Port number]</code>

== 子結構說明 ==
* urls.py - url 網頁路徑傳送門
* views.py - 顯示的方式

==urls.py 基礎==
假設urls.py 的所屬目錄包含 views.py，views.py有user這個函數，我們要傳字串/user/abc 的 abc 當成 user 函數的 username 變數，則可以這樣設定：
<pre>
from django.contrib import admin
from django.urls import path

from . import views

urlpatterns = [
    path('/users/<slug:username>', views.user),
    path('admin/', admin.site.urls),
]
</pre>

==view.py==

假設要做 activitypub 協定，回傳 json 的話，可以這樣設定：

<pre>
from django.http import Http404, JsonResponse
from . import config # import the config variables in the file './config.py'.

def user(request, username):
    user_json = {"@context": "https://www.w3.org/ns/activitystreams",
        "id": config.site_url + "/users/" + username,
        "inbox": config.site_url +  "/users/" + username + "/inbox",
        "outbox": config.site_url + "/users/" + username + "/outbox",
        "type": "Person", # the json for the type
        "name": username , # user name
        } 

    if username != 'John':
        raise Http404() # throw 404
    else:
        return JsonResponse(user_json)
</pre>

如果不是 John，就回傳 Http404()。
