第8章完善博客

8-1 博主頁面開發

8.1.1 列表編寫思路：

取出數據庫中全部的文檔對象；（Python中一切皆對象!）
將文章對象們打包成列表，傳遞到前端頁面；
前端頁面把文章以標題超連接的形式逐個列出；

models.py文件修改；

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.shortcuts import render
from django.http import HttpResponse
from blog import models


# Create your views here.

def index(request):
    # return HttpResponse('Hello World!cuixiaozhao')
    # return render(request, 'blog/index.html', {'hello': 'Hello,Django Blog!'})
    # article = models.Article.objects.get(pk=3)
    articles = models.Article.objects.all()
    print(articles)
    return render(request, 'blog/index.html', {'articles': articles})

index.html模板文件修改；

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>DjangoTemplates</title>
    <meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>
<h1>
    <a href="">新文章</a>
</h1>
{% for article in articles %}
    <a href="">{{ article.title }}</a>
    <br>
{% endfor %}

</body>
</html>

8-2 博客文章頁面開發

8.2.1 文章標題；

8.2.2 文章內容

8.2.3 修改文章按鈕（超連接）

blog/views.py;

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.shortcuts import render
from django.http import HttpResponse
from blog import models


# Create your views here.

def index(request):
    # return HttpResponse('Hello World!cuixiaozhao')
    # return render(request, 'blog/index.html', {'hello': 'Hello,Django Blog!'})
    # article = models.Article.objects.get(pk=3)
    articles = models.Article.objects.all()
    # print(articles)
    return render(request, 'blog/index.html', {'articles': articles})


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

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

blog/article_page.html;

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>ArticlePages</title>
    <meta name="viewport" content="width=device-width, initial-scale=1">

<body>
<h1>{{ article.title  }}</h1>
<br></br>
<h3>{{ article.content }}</h3>
<br>
<br>
<a href="">修改文章</a>
</body>
</html>

8-3 Django模板中的超連接配置

8.3.1 在urls.py中添加namespace = ''

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

8.3.2 修改blog/urls.py中參數的傳遞；

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

8.3.3 修改templates文件index.html中的href參數地址指向；

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>DjangoTemplates</title>
    <meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>
<h1>
    <a href="">新文章</a>
</h1>
{% for article in articles %}
    <a href="{% url 'blog:article_page' article.id %} ">{{ article.title }}</a>
    <br>
{% endfor %}

</body>
</html>

8-4 博客撰寫頁面開發(一)

8.4.1 標題編輯欄；

views.py;

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.shortcuts import render
from django.http import HttpResponse
from blog import models


# Create your views here.

def index(request):
    # return HttpResponse('Hello World!cuixiaozhao')
    # return render(request, 'blog/index.html', {'hello': 'Hello,Django Blog!'})
    # article = models.Article.objects.get(pk=3)
    articles = models.Article.objects.all()
    # print(articles)
    return render(request, 'blog/index.html', {'articles': articles})


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


def edit_pages(request):
    return render(request,'blog/edit_page.html')


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,'blog/index.html',{'articles':articles})

8.4.2 文章內容編輯區域；

8.4.3 提交按鈕；

8-5 博客撰寫頁面開發(二)

8.5.1 編輯頁面開發思路；

新文章爲空，修改文章有內容；
修改文章頁面有文章對象；
文章的ID；

from __future__ import unicode_literals

from django.db import models


# Create your models here.

class Article(models.Model):
    title = models.CharField(max_length=32, default='Title')
    content = models.TextField(null=True)
    # pub_time = models.DateField(auto_now=True)
    pub_time = models.DateTimeField(null=True)

    def __unicode__(self):  # Python2的用法；
        # def __str__(self):   Python3的用法；
        return self.title

admin.py;

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.contrib import admin
from models import Article


# Register your models here.
class ArticlAdmin(admin.ModelAdmin):
    list_display = ('title', 'content', 'pub_time',)
    list_filter = ('pub_time',)


admin.site.register(Article, ArticlAdmin)
