Question

How can I add multiple objects in a find condition?
I created a table for comments but I want to display comments posted by a user and
his or her friends.
I got the find method to return a list of comments by a user’s friends but I cannot get the
‘find’ method to include the user as well.

For example:

User = profile.find(1)
Comment.find(:all, :conditions => {:profile_id => user.friends})

This works great but I also need to have the current user in the list of comments as well.
I tried this with no luck:

Comment.find(:all, :conditions => {:profile_id => [user, user.friends]})

Any advice?

Try this:

Comment.find_all_by_profile_id([user.friends, user].flatten)

Same as:

Comment.all(:conditions => {:profile_id => [user.friends, user].flatten})
