In the setup of  
class Group \< ActiveRecord::Base  
has\_many users :through =\>user\_groups  
end

class User …  
…  
end

for “admin” like behavior (i.e. we want to see any/all users associated  
with this group), this is enough.  
However, in other cases, I want something like

class Group \< ActiveRecord::Base  
has\_many users :through =\>user\_groups, :conditions =\>  
“user\_groups.user\_status\_for\_this\_group = ‘OK’”  
end

what is the best way to do both simultaneously (without resorting to  
something like:  
user\_groups.scoped\_by\_user\_status\_for\_this\_group(‘OK’).collect { |ug|  
ug.user} etc…
