Scott, this is what I have done. I checked out satchmo trunk and keep it updated. After checkout I exported it to a new copy and check it in on my own SVN, and there I make my changes. When ever there is a change in satchmo trunk I merge these changes into my own copy. It's a bit of extra work but that way I can take advantage of improvements and bug fixes in main satchmo and also make patches if I do something of benefit for satchmo.
It might be possible to do it some other way, but I like to develop in line with newforms-admin branch and have done these changes to "my" satchmo, as well as some other structural changes I hope to offer back once they branch to start develop with newforms-admin as base. I read your post in satchmo group but don't really have any input for the special things you trying to achive. In fact, I am pretty new to django/python as well coming from php. If you are interested in using newforms-admin there is a script here http://www.djangosnippets.org/snippets/603/ which help you to do this change quite easily. That's what I used and the script really works. /Joakim On May 1, 2:20 am, Scott SA <[EMAIL PROTECTED]> wrote: > Hi Rajesh, > > On 4/30/08, Rajesh Dhawan ([EMAIL PROTECTED]) wrote: > > >> Is there a reasonable/accptable ot better yet "recommended" way to add > >functionality, etc. to an app without resorting to the above points?
