搜索和ReadMore

在my_blog/article/views.py中添加查询逻辑

def blog_search(request):

if 's' in request.GET:

s = request.GET['s']

if not s:

return render(request,'home.html')

else:

post_list = Article.objects.filter(title__icontains = s)

if len(post_list) == 0 :

return render(request,'archives.html', {'post_list' : post_list,

'error' : True})

else :

return render(request,'archives.html', {'post_list' : post_list,

'error' : False})

return redirect('/')

这里为了简单起见, 直接对archives.html进行修改, 使其符合查询逻辑

{% extends "base.html" %}

{% block content %}

{% if error %}

没有相关文章题目

{% else %}

{% for post in post_list %}

{{ post.title }}

Time:  {{ post.date_time |date:"Y /m /d"}} {{ post.category }}

{% endfor %}

{% endif %}

{% endblock %}

添加了if判断逻辑, 然后还需要修改views中的archives

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})

最后添加my_blog/my_blog/urls.py设置url

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\d+)/$','article.views.detail', name='detail'),    url(r'^archives/$','article.views.archives', name ='archives'),    url(r'^aboutme/$','article.views.about_me', name ='about_me'),    url(r'^tag(?P\w+)/$','article.views.search_tag', name ='search_tag'),    url(r'^search/$','article.views.blog_search', name ='search'),)

ReadMore功能

对于ReadMore的前段按钮界面设置早已经添加过了, 所以这里只需要进行简单的设置就好了

通过使用Django中内建的filter就可以速度实现

{{ value|truncatewords:2 }} #这里2表示要显示的单词数, 以后的会被截断, 不在显示

这里只需要修改my_blog/templates/home.html界面中的变量的过滤器

#将正文截断设置为10

{{ post.content|custom_markdown|truncatewords_html:100 }}

在浏览器中输入http://127.0.0.1:8000/可以看到效率(最好把博文设置的长一些)
