If your package changes its data model, you have to write an + upgrade script. This is very easy in OpenACS.
First, you want to make sure you change the original .sql + file so that new installation will have the new data model.
Next, check what version your package is currently at. For example, it may be at version 1.0b1. Create a file in - sql/postgres/upgrade called packagename-1.0b1-1.0b2.sql and put + yourpackage/sql/postgres/upgrade called packagename-1.0b1-1.0b2.sql and put the SQL code that will update the data model. For example, if you add in a column, you would have an alter table add column statement in this file. Test this out very well, because data model changes are more serious and fundamental changes than the - program .tcl files.
- -Now use the APM to create a new package version + program .tcl files.
Now use the APM to create a new package version 1.0b2. Commit all your changes, tag the release (the section called “Distributing upgrades of your package”), and both new installations and upgrades - will be taken care of.
