這一章節說的東西都是一些知識回顧,
歸檔
歸檔就是列出當前博客中所有的文章, 并且能夠顯示時間, 很容易的可以寫出對應的view和模板來
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中添加對應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
這個就不多說了
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, 內容如下, 大家可以自定義自己喜歡的簡介
{% extends "base.html" %}
{% load custom_markdown %}
{% block content %}
<div class="posts">
<p> About Me 正在建設中 </p>
</div><!-- /.blog-post -->
{% endblock %}
并在my_blog/my_blog/usls.py中添加對應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/$', 'article.views.about_me', name = 'about_me'),
)
標簽分類
實現功能: 點擊對應的標簽按鈕, 會跳轉到一個新的頁面, 這個頁面是所有相關標簽的文章的羅列
只需要在在my_blog/my_blog/view.py下添加新的邏輯
def search_tag(request, tag) :
try:
post_list = Article.objects.filter(category__iexact = tag) #contains
except Article.DoesNotExist :
raise Http404
return render(request, 'tag.html', {'post_list' : post_list})
可以看成是對tag的查詢操作, 通過傳入對應點擊的tag, 然后對tag進行查詢
在對應的有tag的html網頁中修改代碼
{% extends "base.html" %}
{% load custom_markdown %}
{% block content %}
<div class="posts">
{% for post in post_list %}
<section class="post">
<header class="post-header">
<h2 class="post-title"><a href="{% url "detail" id=post.id %}">{{ post.title }}</a></h2>
<p class="post-meta">
Time: <a class="post-author" href="#">{{ post.date_time |date:"Y M d"}}</a> <a class="post-category post-category-js" href="{% url "search_tag" tag=post.category %}">{{ post.category|title }}</a>
</p>
</header>
<div class="post-description">
<p>
{{ post.content|custom_markdown }}
</p>
</div>
<a class="pure-button" href="{% url "detail" id=post.id %}">Read More >>> </a>
</section>
{% endfor %}
</div><!-- /.blog-post -->
{% endblock %}
仔細看這一句<a class="post-category post-category-js" href="{% url "search_tag" tag=post.category %}">{{ post.category|title }}</a>. 其中標簽對超鏈接已經發生改變, 這是在對標簽就行點擊時, 會將標簽作為參數, 傳入到對應的view中執行邏輯, 然后進行網頁跳轉...
并在my_blog/my_blog/usls.py中添加對應url配置
from django.conf.urls import patterns, include, url
from django.contrib import admin
urlpatterns = patterns('',
# Examples:
# url(r'^$', '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'),
)
現在在瀏覽器中輸入http://127.0.0.1:8000/, 點擊對應的歸檔或者ABOUT ME 或者標簽按鈕可以看到對應的效果
