Django ship a default action “Delete selected <objects>”, how can we add a new action? It is easy to do that. All you need to do are in admin.py where the model admins are registered.
First write your action handler function like this
def tasks_finished( modeladmin, request, queryset ):
queryset.update( finished = True )
tasks_finished.short_description = "Mark these tasks as finished"
Then register the handler in your model admin site
class TaskAdmin( admin.ModelAdmin ):
list_display = [ "project", "title", "user", "works", "time", "finished" ]
list_filter = [ "finished", "user", "project" ]
inlines = [ WorkAdminInline ]
ordering = [ "project", "finished", "user", "title" ]
actions = [ tasks_finished ]
That is all you need to do.
After upgrade to django 1.2.1, I encountered csrf porblems. I did these things to fix it:
modify settings.py, add
try:
from django.middleware import csrf
MIDDLEWARE_CLASSES += (
'django.middleware.csrf.CsrfViewMiddleware',
'django.middleware.csrf.CsrfResponseMiddleware',
)
except:
pass
below
MIDDLEWARE_CLASSES = (
......
)
add {% csrf_token %} in templates/admin/login.html ( Guess you must have override the login.html based on the old version ). The template tag csrf_token is default tag, you don’t need to load any extra tag libraries.
Don’t forget to restart your server.

return "";
}
ob_start();
include( $file );
$cnt = ob_get_clean();
return $cnt;
}

You can download the test code from the example.
I like firebug, but the firefox/firebug goes unstable in my MAC OS. I have to use Safari. I’m a web application programmer, I get to debug my sites, and I need a debug bar like firebug. Thanks that Safari has its own develop tool. By default, it is hidden, Of course, not all who use safari a developper. I get to enable it:
Safari -> Preferences… -> Advanced -> Show Develop menu in menu bar
Once youe turn on the checkbox, there will be a menu appear in Safari menu bar named “Develop“, click submenu “Show Web Inspector“, something linke firebug will appear at the bottom of the browser. Wow, why it is so like Google Browser’s Develop Tool?
Click and hold the bookmark item, then drag it off the bar, release your mouse, and the bookmark gone from your bookmark bar. If you are deleting the bookmark folder, after you drag off it from the bar and release the mouse, a confirm box will appear. Just delete them, I dislike the function of bookmark, for google remember everything for me, and I just remember google.
You can hide the bookmark bar by menu operation: View -> Hide Bookmarks Bar
Now it completely gone, I like a clean browser.

You can install OpenSSHd from Cydia. Search OpenSSH and install it. After that, you can connect to your iPhone via ssh, there are 2 users created for you, mobile and root. The default password is alpine, you should change that as soon as possible.
Example:
huangxh@agamemnon:~$ ssh mobile@10.6.175.246
mobile@10.6.175.246′s password: [alpine]
Huang-Jiang-Bins-iPhone-3:~ mobile$ passwd
Changing password for mobile.
Old password: [alpine]
New password: [your password]
Retype new password: [your password]
Huang-Jiang-Bins-iPhone-3:~ mobile$ su
Password: [alpine]
Huang-Jiang-Bins-iPhone-3:/var/mobile root# passwd
Changing password for root.
New password: [your password]
Retype new password: [your password]
