Making changes to django model after going live

Hi,

I know that every time I make a change to my Django model, I have to delete my database and create a new one before running manage.py syncdb. I was going to release my app soon and was wondering how I could go about making changes to my database once I release it.

Thanks.

There is basically 2 things I do to solve this,

Install south, http://south.aeracode.org/

Or, basically a juggle between dev and live databases and sites where I will manually integrate the data from the old DB to the new ones schema, this process I reserve for older sites that I have no other choice in the matter and upgrade to south ASAP.

I might add that in the case of the manual route the manage.py sql* commands are very useful, https://docs.djangoproject.com/en/dev/ref/django-admin/#sql-appname-appname

Hey, I installed South and tried running the 'python2.7 manage.py convert_to_south appname' command...but it gives me the error 'There is no enabled application matching 'appname''. I was wondering what could be wrong?

Does the Django App in question exist? Note that this is a "Django App", not a webfaction app directory (~/webapps/appname). A "Django app" is an isolated bit of code with its own models.py file and could possibly be included in your INSTALLED_APPS.

Ah, I had two apps within my 'major app'...had forgotten that's how I had built them. My bad. Thanks for your time :)

0	South is my tool of choice. You can also try Nashvegas. permanent link answered 22 Aug '11, 09:46 tclancy 86●1●8●15 accept rate: 6%
