Question

I’m using a gem that doesnt work on the arrays from the find_all_by() method, but does with the .where(); however, I don’t know how to write it in a way that produces the same result.

For instance, how could I rewrite:

Post.find_all_by_poster(@user.id , :conditions => ['title IS NOT NULL OR name !=?', 'Bob' ])

My attempt:

Post.where("poster = ? AND title !=? OR name !=?", @user.id, 'NULL', 'Bob')

Any ideas? I’m having trouble satisfying the same conditions. Thanks for your help!

You still need to use IS NOT NULL instead of passing in NULL as a separate parameter:

Post.where("poster = ? and (title is not null or name != ?)", @user.id, 'Bob')
