1,Create a project
33. Run the script file in the python directory.
Django-admin.py startproject mysite
In this way, a project named mysite is generated.
Execute. \ manage. py runserver to run the development server. At this time, the terminal will output
Log on to http: // 127.0.0.1: 8000/. The page is displayed.
At the same time, the token will output [13/Aug/2014 01:05:14] "Get/HTTP/1.1" 200 1957
Timestamp, request, HTTP status code, and number of bytes from left to right
2,CreateBlogApplication
Execute. \ manage. py Startapp blog
In this way, the blog app is created, and the blog directory is under the project (mysite) directory.
Then you need to find the installed_apps tuples in siteid. py under the mysite directory, and add 'blog. app' to the end of the tuples (note the comma)
3,DesignModel
Add the following code to models. py:
From Django. DB import models
From Django. contrib import Admin
Class blogpost (models. Model ):
Title = models. charfield (max_length = 150)
Body = models. textfield ()
Timestamp = models. datetimefield ()
4,Set Database
If sqlite3 is used, you only need to complete the first two items in the databases Dictionary of setting. py, namely, 'engine': 'django. DB. backends. sqlite3'
'Name' = *** \ Django. DB # indicates the data storage address, which is customized.
Execute. \ manage. py syncdb # synchronize the data terminal, and the following output is displayed.
Creating table auth_message
Creating table auth_group
........
You will be asked questions about Django. contrib. Auth app.
5. Set the automatic admin Application
Add the following line under 'django. contrib. auth' in settings. py:
'Django. contrib. admin'
Then run the syncdb command again,
After setting the app, you must specify a URL for it.
Remove the annotator before RL (R' ^ admin/', include (Admin. Site. URLs) in URLs. py.
Finally, import admin in models. py
From Django. contrib import Admin
Add a line of model registration code at the end.
Admin. Site. Register (blogpost)
6. log on to 127.0.0.1: 8000/admin using admin and enter the user name and password. The page is displayed.
Edit several blogs and save them as needed. Add the blogpostadmin class to the models. py file to make the notebook list more beautiful, and add it to the registration code.
From Django. DB import models
From Django. contrib import Admin
Class blogpost (models. Model ):
Title = models. charfield (max_length = 150)
Body = models. textfield ()
Timestamp = models. datetimefield ()
Class meta:
Ordering = ('-timestamp ',)
Class blogpostadmin (Admin. modeladmin ):
List_display = ('title', 'timestamp ')
Admin. Site. Register (blogpost, blogpostadmin) # regiet blogpost Model
Refresh the page and you will see
Compared with the original title and timestamp columns
7. Create a public part of the blog.
Create an archive.html file and save it to blog \ templates as follows:
{% For post in posts %}
<H2 >{{ post. Title }}</H2>
<P >{{ post. timestamp | date }}</P>
<P >{{ post. Body }}</P>
{% Endfor %}
Create a view function, open the blog \ view. py file, and enter:
From Django. template import loader, Context
From Django. Http import httpresponse
From mysite. Blog. Models import blogpost
Def archive (request ):
Posts = blogpost. Objects. All ()
T = loader.get_template('archive.html ')
C = context ({'posts': Posts })
Return httpresponse (T. Render (c ))
Then create the URL mode and add it in mysite/URLs. py.
URL (R' ^ blog/', include ('mysite. Blog. urls ')),
This will capture any requests starting with blog/and pass them to the following URL Mode
Mysite/blog/URLs. py:
From Django. conf. URLs. defaults import *
From mysite. Blog. Views import Archive
Urlpatterns = patterns ('',
URL (R' ^ $ ', archive ),
)
8. Last retouching
Create a base.html file and save it in mysite/blog/templates as follows:
<HTML>
<Style type = "text/CSS">
Body {color: # cdcdcd; backgroud: # cdcdcd; padding: 0 5em; margin: 0}
H1 {padding: 2em 1em; backgroud: #675}
H2 {color: # cdcdcd; border-top: 1px dotted # cdcdcd; margin-top; 2em}
P {margin: 1em 0}
</Style>
<Body>
<H1> mysite.example.com
{% Block content %}
{% Endblock %}
</Body>
</Html>
Then update achive.html:
{% Extends "base.html" %}
{% Block content %}
{% For post in posts %}
<H2 >{{ post. Title }}</H2>
<P >{{ post. timestamp | date }}</P>
<P >{{ post. Body }}</P>
{% Endfor %}
{% Endblock %}
Log on to http: // 127.0.0.1: 8000/blog/
You can add a nested class Meta to the models. py file: Sort blogs in order.
From Django. DB import models
From Django. contrib import Admin
Class blogpost (models. Model ):
Title = models. charfield (max_length = 150)
Body = models. textfield ()
Timestamp = models. datetimefield ()
Class meta:
Ordering = ('-timestamp ',)
Class blogpostadmin (Admin. modeladmin ):
List_display = ('title', '-timestamp ')
Admin. Site. Register (blogpost, blogpostadmin) # regiet blogpost Model
'-Timestamp' indicates the descending 'timestamp'.
