這篇文章主要介紹了利用django創(chuàng)建一個(gè)簡(jiǎn)易的博客網(wǎng)站的示例，幫助大家更好的學(xué)習(xí)和使用django框架，感興趣的朋友可以了解下

一、頁(yè)面實(shí)現(xiàn)

index.html
base.html
post.html
header.html
footer.html

<!-- index.html-->
{% extends 'base.html' %}
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>個(gè)人博客</title>
</head>
<body>
<h1>歡迎來(lái)到我的博客</h1>
{% for post in posts %}
  <hr>
  <p style="font-family: 微軟雅黑 ">
  <a href="/post/{{ post.slug }}" rel="external nofollow" rel="external nofollow" >{{ post.title }}</a>
  </p>
{% endfor %}

{{ now }}

</html>
<div class="mainContext">

    {% block title %}歡迎來(lái)到我的博客{% endblock %}
    {% block headmessage %}<h3 style="font: 微軟雅黑;">文章列表</h3>{% endblock %}
    {% block content %}

    {% endblock %}
</div>
</div>

<!-- base.html-->

  </div>
</div>
</body>
</html>

<!-- post.html-->
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>post</title>
</head>
<body>
<a href="http://localhost:8000/" rel="external nofollow" >返回上一頁(yè)</a><br/>
{{ post.body }}
</body>
</html>

<!-- footer.html-->
{% block footer %}
  {% if now %}
    <p style="font-family: 微軟雅黑">時(shí)間：{{ now }}</p>
  {% else %}
    <p style="font-family: 微軟雅黑">如需轉(zhuǎn)載請(qǐng)注明來(lái)源</p>
  {% endif %}
{% endblock %}

models.py 數(shù)據(jù)表的設(shè)計(jì)

from django.db import models
from django.utils import timezone
from tinymce.models import HTMLField
# Create your models here.
class Post(models.Model):
  title = models.CharField(max_length = 200,verbose_name=u'標(biāo)題')#標(biāo)題
  slug = models.CharField(max_length=200,verbose_name=u'文章網(wǎng)址')#文章網(wǎng)址
  body = models.TextField()#文章內(nèi)容
  tags = models.CharField(max_length=100, verbose_name=u'標(biāo)簽')
  pub_date = models.DateTimeField(default = timezone.now)#發(fā)表時(shí)間

  #pub_date 以timezone.now的方式讓其自動(dòng)產(chǎn)生時(shí)間 在執(zhí)行需要pytz模塊支撐
  class Meta:
    db_table = '博客'
    ordering = ['pub_date']#按照發(fā)表時(shí)間排序顯示順序依據(jù)
    def __str__(self):#設(shè)置此類所提供的數(shù)據(jù)項(xiàng)，顯示文章標(biāo)題
      return self.title

數(shù)據(jù)表的遷移在cmd中執(zhí)行

python manage.py makemigrations
python manage.py migrate

views.py 方法的實(shí)現(xiàn)

#初始頁(yè)面 顯示所有文章列表
def homepage(request):
  posts = Post.objects.all().order_by('-pub_date')
  return render(request, 'index.html', locals())
  now = datetime.now()
  #顯示文章內(nèi)容
def show_detail(request,slug):
  try:
    post = Post.objects.get(slug = slug)
    if post != None:
      return render(request,'post.html',locals())
  except:
    return redirect('/')#返回首頁(yè)
#在views中調(diào)用屬于同一個(gè)標(biāo)簽文章
def search_tag(request): #tag在URL中獲取
  tag = request.GET.get('p')
  print(tag)
  try:
    posts = Post.objects.filter(tags=tag)#注意這里寫(xiě)的是filter
    if posts != None:#這里使用的是posts，和index.html中對(duì)應(yīng)
      return render(request,'index.html',locals())
  except:
    print('沒(méi)找到')

url.py在url中注冊(cè)路徑

from django.conf.urls import url, include
from django.contrib import admin
from django.urls import path
from myblogs import views
#import tinymce
urlpatterns = [
  path('', views.homepage),#進(jìn)入系統(tǒng)主頁(yè)
  path('admin/', admin.site.urls),#進(jìn)入管理員頁(yè)面
  path('post/<slug:slug>/',views.show_detail),#顯示詳細(xì)信息# 定義拼接地址，獲取標(biāo)簽信息  
  url(r'^tag/$', views.search_tag)#注意這里使用的是url 和正則表達(dá)式 需要前文中引入
  #url(r'^tinymce/', include('tinymce.urls')), # 這是富文本編輯器
]

在界面中添加css或者是圖片

配置setting

STATIC_URL = '/static/'
STATICFILES_DIRS = [
  os.path.join(BASE_DIR, 'static'),
]

在界面中引入

1.方法一
{% load staticfiles %}
<title>{% block title %} {% endblock %}</title>
2.方法二
{% load staticfiles %}
<link rel="stylesheet" href="{% static 'index.css' %}" rel="external nofollow" >
