Re: svn commit: r1242755 - in /incubator/bloodhound/trunk/bloodhound_multiproduct: ./ LICENSE NOTICE multiproduct/ multiproduct/__init__.py multiproduct/model.py setup.py tests/ tests/__init__.py tests/model.py

Hi,

Just added the bare basics of a multi product plugin - the schema, table 
generation and so on. Still requires installation instructions. I will 
also add an admin panel based very strongly on the trac template soon 
(though I wouldn't mind knowing if those commits need to have an 
appropriate mention of such lineage).

Quick note: this is intended to be equivalent to providing the multi 
project feature but with a slight change in nomenclature.

Cheers,
     Gary

That is fantastic. Personally I would be very happy to see this work put 
into bloodhound as there is some very useful work there. I was under the 
impression that your multiproduct plugin was looking at a different 
level to my work but, even if that is true, it should go a long way 
towards solving other problems.

Thanks Mat!

Cheers,

Also relevant:

Now that I have fixed my personal website, I'd like to share a couple
of plug-ins I've written in the past for Trac. The first is
rudimentary support for multiple products, as a patch to the Trac core
and a companion plug-in, rather uninventively named MultiProduct:

http://matbooth.co.uk/trac/wiki/MultiProductStart

It was written a couple of years ago now so it was written for Trac
0.11 but it does exciting things like add a new ticket field type to
facilitate having product dependant components and product dependant
versions. You can read more at the link above and by all means Gary,
steal as much of it as you like if it is useful to your multi-product
effort -- it's proven too as I know of at least two companies using it
in production in their internal Trac installs in addition to my
personal Trac at matbooth.co.uk :-)

We should sit down and discuss merging our efforts, maybe. What are
your thoughts Gary?

The second plug-in I'm responsible for is called TicketValidation:

http://matbooth.co.uk/trac/wiki/TicketValidationStart

Which was created in response to make certain ticket fields mandatory
for certain ticket types. Basically it's a way of configuring boolean
expressions to determine if a ticket field is mandatory based on the
values of the other fields. It also supports hiding fields from view
in a similar way. It's a little more rough and ready than my
MultiProduct plug-in, but again there is at least company I know of
using it production.

I would be happy to move these two plug-ins wholesale to the
BloodHound project if you guys like them. I can then spend some time
updating them to work with the latest version of the Trac code base.

Enjoy!
