JOIN conditions
Hi,
how can I get Rails to generate SQL queries with conditions in the JOIN clause?
What I would want is:
SELECT * FROM people p
LEFT OUTER JOIN jobs j (p.job_id = j.id AND j.salary > 9999999)
I tried
People.find(:all, :include => ''jobs'', :conditions => ''jobs.salary > 9999999'')
but that generates
SELECT * FROM people p
LEFT OUTER

changing find method
Hi,
i was wondering if there was a nice clean way(after all, it is ruby) to
change the find method of a certain model/class (Page) so that if i
wanted to use a find method on a @page instance it would return only
specific rows from the table(if the page.published == true/false:
the pages table looked like
SQL:

one-to-one, compound primary key, naming conventions
My understanding is that, given tables Alpha and Beta that the table
which holds the 1-to-1 relation will be called Alpha_Beta (or is it
alpha_beta?). So far so good.
alpha_beta will have, lets say, two fields: alpha_id and beta_id. Seems
that it''d be a good idea for those two fields to form a compound primary
key, ensuring there are no duplicates.
However, RoR doesn''t

HABTM - how to insert join row when associated rows exist
I have successfully used HABTM to create a many-to-one-to-many set of
rows in one step. Now, if two objects I want to associate already exist,
how do I create the join row? The Agile book mentions the
''push_with_attributes'' method. The text says this method is useful for
adding additional attributes to the join row (in the example a ''read_at''
timestamp). I

I really need to have the ability to tie event channel port''s to
interrupts for my gplpv drivers under Windows. Is anyone working on
anything like this? Does MSI allow more than one interrupt per PCI
device?
Thanks

Hello, All,
Today one of our servers was crashed, after I rebooted the server, one
vps can not boot up, and it needs fsck, after I run fsck command, a
lot of files lost, and also some file content was changed. Not sure
how could it happen, do you have any advice that can avoid this or
recover the data?
Thanks.

behaviour of ''xm block-attach'' changed with 3.1.2?
''xm block-attach'' doesn''t let me assign the same backend device anymore,
even if I use ''r!'' or ''w!''.
I think this has changed since 3.1.1 (or maybe since 3.1.0).
Is this the way it is supposed to work?
Thanks

HVM windows - PCI IRQ firing on both CPU''s
I''m just doing some testing on the gplpv drivers with different ways of
handling interrupts, and I''m trying a scheme where each xen device (eg
vbd/vif) driver attaches to the same IRQ as the pci driver, and each
handles it in sequence.
In testing though, I noticed the following when logging what each ISR is
doing:
60.32381439 - evtchn event on port 5
60.32384109 - port 5
