In this section we will look at the use of templates and views, URLs.
I. Using a templateCreate a new Templates folder in the blog directory and create a new base.html file under the Templates folder. The directory structure is as follows
View Codetemplates/ base.html
Writing base.html files
<!DOCTYPE HTML><HTMLLang= "en"><Head> <MetaCharSet= "UTF-8"> <title>{% block title%} {% Endblock%}</title></Head><Body> <H1>A simple blog</H1>{% block content%} {% Endblock%} {% block footer%}<P>Thanks for visiting my site!</P>{% Endblock%}</Body></HTML>View Code
Base.html defines a simple HTML framework that will then be used on all pages.
Create a new blog_list.html under the Templates directory
{% extends "base.html"%}{% block title%} Blog list {% endblock%}{% block content%}<Divclass= "Content">{% for blog in blogs%}<H3>{{Blog.caption}}</H3> <Div>{{Blog.content}}</Div>{% endfor%}</Div>{% Endblock%}View CodeTwo. Configure the View file
Edit views.py in the blog directory
from Import Render_to_response from Import Blog def blog_list (Request): = Blog.objects.all () return render_to_response ("blog_list.html ", {"blogs": Blogs})Edit urls.py in the Web directory
urlpatterns = Patterns ( " , # Examples: # URL (r ' ^$ ', ' web.views.home ', name= ' home '), # URL (r ' ^blog/', include (' Blog.urls ')), URL (r ' Add a urls.py file to the blog directory
from Import *= patterns ('blog.views'), URL (r' ^bloglist/$ ' ' blog_list ', name='bloglist'),)Use admin to add a few tags, blog, and author, finally run the server, open 127.0.0.1:8000/web/bloglist, display the following interface
Iv. Add a blog display pageAdd blog_show.html in the Templates directory.
{% extends "base.html"%}{% block title%} {{blog.caption}} {% Endblock%}{% block content%}<Divclass= "Content"> <H2>Blog Show</H2> <h4>{{Blog.caption}}</h4> <Div>{{Blog.content}}</Div></Div>{% Endblock%}View Code
Adding Blog_show View functions in the views.py file
From django.http import http404def blog_show (Request, id= "): try: blog = Blog.objects.get (id=id) except Blog.doesnotexist: raise Http404 return render_to_response ("blog_show.html", {"blog": Blog})Modify the blog directory below the urls.py, add the following content
URL (r'^blog/(? p<id>\d+)/$','blog_show', name=' Detailblog'),
Modify Blog_list.html
< H3 > {{Blog.caption}} </ H3 >Change it to
< H3 > < href= "{% url ' detailblog ' blog.id%}"> {{blog.caption}} </ a > </ H3 >The special note is that Detailblog must bring the single quotation mark, again refreshes the next blog_list page, the blog title handy becomes the link.
