Removing Product Types from Repository Manager
Hi,
I am curious about the removeProductType() method in the following class :
https://svn.apache.org/repos/asf/oodt/trunk/filemgr/src/main/java/org/apache/oodt/cas/filemgr/repository/DataSourceRepositoryManager.java
<https://svn.apache.org/repos/asf/oodt/trunk/filemgr/src/main/java/org/apache/oodt/cas/filemgr/repository/DataSourceRepositoryManager.java>Since
each Product is a member of a single Product Type, don't we have to delete
all the Products of the deleted Product Types too (i..e reference and
metadata table.) ?
I read the TODO comment and I am just curious as to why the deletion was not
done here or rather, the reason behind the assumption in the comment.
Thanks,
--
Sheryl

Oh Ok. Got it.
It makes sense now. I thought the ProductType ID was a key constraint for
Products table too. I checked the SQL files and realized that disabling or
removing the Product Types wouldn't create a problem here.
Thanks!

Hi Sheryl,
I think the thinking there was that a user may in fact use "removeProductType" to simply "disable" a product type, but may later somehow want to undo that.
Ideally the function should have an option as to whether or not to actual remove the met and refs tables, but that's not there, yet... ^_^ Patches welcome!
Cheers,
Chris

Hi Sheryl,
I think the thinking there was that a user may in fact use "removeProductType" to simply "disable" a product type, but may later somehow want to undo that.
Ideally the function should have an option as to whether or not to actual remove the met and refs tables, but that's not there, yet... ^_^ Patches welcome!
Cheers,
Chris
