Admin

配置

Django Shell

小技巧：

過濾器

edit_page.html

<form?action="{%?url?'myblog:edit_action'?%}"?method="post">
????{%?csrf_token?%}?<!--防攻擊，不加的話會403錯誤。post方法都需要添加csrf?-->
????<label>文章標(biāo)題
????????<input?type="text"?name="title"/>
????</label>
????<br/>
????<label>文章內(nèi)容
????????<input?type="text"?name="content"/>
????</label>
????<br/>
????<input?type="submit"?value="提交">
</form>

views.py

def?edit_action(request):
????title?=?request.POST.get('title',?'TITLE')
????content?=?request.POST.get('content',?'CONTENT')
????models.Article.objects.create(title=title,?content=content)
????articles?=?models.Article.objects.all()
????return?render(request,?'myblog/index.html',?{'articles':?articles})

myblog/urls.py 添加url

url(r'^edit/action$',?views.edit_action,?name='edit_action'),

hf_blog/urls.py 添加namespace

urlpatterns?=?[
????url(r'^admin/',?admin.site.urls),
????url(r'^myblog/',?include('myblog.urls',?namespace='myblog'))
????]

mybog/urls.py 添加name

urlpatterns?=?[
????url(r'^index$',?views.index),
????url(r'^article/(?P<article_id>[0-9]+)$',?views.article_page,?name='article_page'),
]

index.html

{%?for?article?in?articles?%}
????<a?href="{%?url?'myblog:article_page'?article.id?%}">{{?article.title?}}</a>
????<br/>
{%?endfor?%}

URl參數(shù)傳遞

url(r'^index$',?views.index),
url(r'^article/(?P<article_id>[0-9]+)$',?views.article_page),

兩url之間需要寫逗號

url正則中組名和參數(shù)名一致

views.py

def?article_page(request,?article_id):
????article?=?models.Article.objects.get(pk=article_id)
????return?render(request,?'myblog/article_page.html',?{'article':article})

創(chuàng)建超級用戶

python?manage.py?createsuperuser

Admin入口

localhost:8000/admin/

后臺修改為中文

setting.py

LANGUAGE_CODE?=?'zh_Hans'

admin.py

from?.?models?import?Article
admin.site.register(Article)

修改后臺文章列表

models.py

def?__str__(self):
????return?self.title

model.py

class?Article(models.Model):
????title?=?models.CharField(max_length=32,?default?='Title')
????content?=?models.TextField(null=True)

生成數(shù)據(jù)

python?manage.py?makemigrations

數(shù)據(jù)遷移

python?manage.py?migrate

查看sql

python?manage.py?sqlmigrate?myblog?0001

添加數(shù)據(jù)

views.py

def?index(request):
????article?=?models.Article.objects.get(pk=1)
????return?render(request,?'myblog/index.html',?{'article':?article})

啟動服務(wù)

python?manage.py?runserver

移植數(shù)據(jù)庫

python manage.py makemigrations

然后

python manage.py migrate

出現(xiàn)post請求的表單都需要在表單下添加{% csrf_token %}

編輯響應(yīng)函數(shù)
