Hi,
we are trying to use BDRB for background processing of long-running
reports, and have two issues - one is that worker does not see our
Report class from Rails, throws a:
/var/apps/ror_trunk/vendor/plugins/backgroundrb/server/master_worker.rb:22:in
`load'': undefined class/module Report (ArgumentError)
from
/var/apps/ror_trunk/vendor/plugins/backgroundrb/server/master_worker.rb:22:in
`receive_data''
And the other is - does this new release work on Windows which some
of our developers use? I know that last releases did not work
because of fork() issues, but the new rewrite has a new networking
model, so do you think it might work with some workarounds?
thanks for your help!

Although, one can probably fix it with Win32 emulation API. Where is this Report class defined? is it a model or loaded from plugins? any code that you are using would be helpful. Technically however, you can put a explicit require of file that defines the class and see if it works. -- Let them talk of their oriental summer climes of everlasting conservatories; give me the privilege of making my own summer with my own coals. http://gnufied.org

I tried "require"''ing it explicitly but then it complains about other models (ActiveRecord ones) used in the report generation. Seems that bdrb is not picking up models in "app/models" at all.

Anyways, just send me the worker code ( if possible model code too ) and complete backtrace of the error. It shouldn''t be a problem. -- Let them talk of their oriental summer climes of everlasting conservatories; give me the privilege of making my own summer with my own coals. http://gnufied.org
