Forum OpenACS Q&A: Difference between Data Model & Data Source
source... can somebody explain?
A data source usually refers to a way to describe the exact database you are talking to. For instance, there may be multiple databases running on a machine, so in order to specify which database you want, you might use a string like "localhost:5432:patrick" to specify that the machine name is "localhost", the TCP/IP port to connect to is "5432" and the name of the database is "patrick".
Usually there are slight differences in the format of the data source depending on which database server (Postgres, Oracle, Sybase) you are using.
Perhaps by looking for a .tcl file with the same file name (e.g.
cal-item.adp will look for cal-item.tcl)?
If the .adp has the same name as the .tcl, just type:
This way you can have more the same .adp used by more than one .tcl.
I found it useful to study other people's code i.e. look in packages/ticket-tracker/www/admin
While we're on the topic, does anyone care to nominate any individual package as the Oscar winner for Best Coded Package? People new to OpenACS could then be pointed at that as a good example of OpenACS coding.
