How to setup your mac terminal page up and page down shortcuts.
Default for page up/ page down in terminal is to scroll the actual terminal, not send a page up / page down command TO the program in the terminal .
In short, open terminal settings > go to key bindings>
set page up to 33[5~
set page down to 33[6~
Note that 33 is the ESC key. Typing in \ on its own will result in an escape slash (or smth): \\
So in this case, type in ESC, [, 6, and ~.
Let me know if it helped!
This was fairly painless procedure: 1 shot did the trick.
LOTS Of googlefu was involved.
Found it in the ModelAdmin class:
list_per_page = 100
class MyAdmin(admin.ModelAdmin):
list_per_page = 2000
Python has a nice string method to check if the string only contains spaces, isspace.
' '.isspace()
will return True
I was converting xml to a dict, and found many multi space empty strings that I needed to test for.
Enjoy!
Gmail push support out of the box on the iphone 4 launch OS doesn’t seem to work as advertised.
Use google sync instead, which makes you speak directly to googles servers. Setup instructions here.
I tested it, I get my email notifications within 1 or 2 seconds.

Chances are, you accidentally subclassed admin.ModelAdmin for a class passed as an inline.
Inlines should subclass the inline admin classes: TabularInline or StackedInline
on if not response.has_header(‘ETag’):
This error appears if you don’t return anything from your view.
return direct_to_template(request, "template")
I wonder if this is a new error message? I recall a more specific error in my previous version of django, something along the lines of “Your view didn’t return anything!”
Database migrations handled easily. Now I can add the migration files that are generated to the GIT repository PER-BRANCH and grab them on the production server when the time comes.
UPDATE 9 months later when I realized this is one of the top results for django south.
I might as well write a simple tutorial on how to use it. Read the South docs, but in as few lines of code as possible, here’s what to do:
pip install South ### modify settings.py and add 'south' to INSTALLED_APPS python manage.py syncdb # adds south tables python manage.py schemamigration myapp --initial # sets up your app for the first migration. python manage.py migrate myapp --fake # "fakes" a migration because you will get an error if you try to migrate # from an existing database setup. You will get a "table already exists" error otherwise. ### modify your app models, then auto-create a migration python manage.py schemamigration myapp --auto # this will auto detect the changes python manage.py migrate myapp # will apply new migration. git add myapp/migrations/ # add migrations to version control ### download migrations on remote machine, and simply type in python manage.py migrate # note: this is after faking the first migration if the database exists.
Hope that helps!
If you’re running Aptana 3 Beta Windows, PyDev isn’t in the default list of addons via their package installer.
To install it, you just need to add the PyDev site to the installer.
PyDev for name, and http://www.pydev.org/updates/ for the location.
