Hi all,

I’ve got an interesting problem. I’m dealing with a legacy database,  
and for one of my models I always want to ignore records that have a  
particular column set. I would like to pretend like they don’t exist.  
When I run MyModel.find() I don’t want them to show in the result set.

I considered using after\_find() to do this, but that gets called on  
every item in the found collection, not the entire collection. Is there  
some easy way to modify MyModel to insert a :conditions statement (or  
modify a pre-existing one) on all queries issued by the model? Ideally  
it would be transparent enough that the other models don’t need to know  
anything about it.

Thanks!

-Brent

Or maybe this guy wrote his idea up.

Zargony refers to the global\_scope plugin. :+)

That happens to _perfectly_ solve my problem. Thanks for the tip!
