這一章節(jié)說(shuō)的東西都是一些知識(shí)回顧,

歸檔

歸檔就是列出當(dāng)前博客中所有的文章, 并且能夠顯示時(shí)間, 很容易的可以寫(xiě)出對(duì)應(yīng)的view和模板來(lái)

在my_blog/my_blog/view下新建歸檔view

def archives(request) :
    try:
        post_list = Article.objects.all()
    except Article.DoesNotExist :
        raise Http404
    return render(request, 'archives.html', {'post_list' : post_list, 
                                            'error' : False})

在my_blog/templates新建模板archives.html

{% extends "base.html" %}

{% block content %}
<div class="posts">
    {% for post in post_list %}
        <section class="post">
            <header class="post-header">
                <h2 class="post-title"><a href="{% url "detail" id=post.id %}">{{ post.title }}</a></h2>

                    <p class="post-meta">
                        Time:  <a class="post-author" href="#">{{ post.date_time |date:"Y /m /d"}}</a> <a class="post-category post-category-js" href="{% url "search_tag" tag=post.category %}">{{ post.category }}</a>
                    </p>
            </header>
        </section>
    {% endfor %}
</div><!-- /.blog-post -->
{% endblock %}

并在my_blog/my_blog/usls.py中添加對(duì)應(yīng)url配置

from django.conf.urls import patterns, include, url
from django.contrib import admin

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'my_blog.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),

    url(r'^admin/', include(admin.site.urls)),
    url(r'^$', 'article.views.home', name = 'home'),
    url(r'^(?P<id>\d+)/$', 'article.views.detail', name='detail'),
    url(r'^archives/$', 'article.views.archives', name = 'archives'),
)

AboutMe

這個(gè)就不多說(shuō)了

在my_blog/my_blog/view.py下添加新的邏輯

def about_me(request) :
    return render(request, 'aboutme.html')

在my_blog/template下新建模板aboutme.html, 內(nèi)容如下, 大家可以自定義自己喜歡的簡(jiǎn)介

{% extends "base.html" %}
{% load custom_markdown %}

{% block content %}
<div class="posts">
        <p> About Me 正在建設(shè)中 </p>
</div><!-- /.blog-post -->
{% endblock %}

并在my_blog/my_blog/usls.py中添加對(duì)應(yīng)url配置

from django.conf.urls import patterns, include, url
from django.contrib import admin

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'my_blog.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),

    url(r'^admin/', include(admin.site.urls)),
    url(r'^$', 'article.views.home', name = 'home'),
    url(r'^(?P<id>\d+)/$', 'article.views.detail', name='detail'),
    url(r'^archives/$', 'article.views.archives', name = 'archives'),
    url(r'^aboutme/$', 'article.views.about_me', name = 'about_me'),
)

標(biāo)簽分類

實(shí)現(xiàn)功能: 點(diǎn)擊對(duì)應(yīng)的標(biāo)簽按鈕, 會(huì)跳轉(zhuǎn)到一個(gè)新的頁(yè)面, 這個(gè)頁(yè)面是所有相關(guān)標(biāo)簽的文章的羅列

只需要在在my_blog/my_blog/view.py下添加新的邏輯

def search_tag(request, tag) :
    try:
        post_list = Article.objects.filter(category__iexact = tag) #contains
    except Article.DoesNotExist :
        raise Http404
    return render(request, 'tag.html', {'post_list' : post_list})

可以看成是對(duì)tag的查詢操作, 通過(guò)傳入對(duì)應(yīng)點(diǎn)擊的tag, 然后對(duì)tag進(jìn)行查詢

在對(duì)應(yīng)的有tag的html網(wǎng)頁(yè)中修改代碼

{% extends "base.html" %}

{% load custom_markdown %}
{% block content %}
<div class="posts">
    {% for post in post_list %}
        <section class="post">
            <header class="post-header">
                <h2 class="post-title"><a href="{% url "detail" id=post.id %}">{{ post.title }}</a></h2>

                    <p class="post-meta">
                        Time:  <a class="post-author" href="#">{{ post.date_time |date:"Y M d"}}</a> <a class="post-category post-category-js" href="{% url "search_tag" tag=post.category %}">{{ post.category|title }}</a>
                    </p>
            </header>

                <div class="post-description">
                    <p>
                        {{ post.content|custom_markdown }}
                    </p>
                </div>
                <a class="pure-button" href="{% url "detail" id=post.id %}">Read More >>> </a>
        </section>
    {% endfor %}
</div><!-- /.blog-post -->
{% endblock %}

仔細(xì)看這一句<a class="post-category post-category-js" href="{% url "search_tag" tag=post.category %}">{{ post.category|title }}</a>. 其中標(biāo)簽對(duì)超鏈接已經(jīng)發(fā)生改變, 這是在對(duì)標(biāo)簽就行點(diǎn)擊時(shí), 會(huì)將標(biāo)簽作為參數(shù), 傳入到對(duì)應(yīng)的view中執(zhí)行邏輯, 然后進(jìn)行網(wǎng)頁(yè)跳轉(zhuǎn)...

并在my_blog/my_blog/usls.py中添加對(duì)應(yīng)url配置

from django.conf.urls import patterns, include, url
from django.contrib import admin

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'my_blog.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),

    url(r'^admin/', include(admin.site.urls)),
    url(r'^$', 'article.views.home', name = 'home'),
    url(r'^(?P<id>\d+)/$', 'article.views.detail', name='detail'),
    url(r'^archives/$', 'article.views.archives', name = 'archives'),
    url(r'^aboutme/$', 'article.views.about_me', name = 'about_me'),
    url(r'^tag(?P<tag>\w+)/$', 'article.views.search_tag', name = 'search_tag'),
)

現(xiàn)在在瀏覽器中輸入http://127.0.0.1:8000/, 點(diǎn)擊對(duì)應(yīng)的歸檔或者ABOUT ME 或者標(biāo)簽按鈕可以看到對(duì)應(yīng)的效果
