create or update_attribute method

rubyonrails-talk

Dear all

Are there any method to create or update something? (if something exist, then update, else create....where something is the primary key)

Something like.... if Klass.find_by_something( xxx )    Klass.update_attribute your_hash else   Klass.create your_hash end

This is similar to the AR dynamic finder Klass.find_or_create_by_something()..., but I want a Klass.create_or_update_by_something...Any idea??

Many thanks Valentino

I don't think so, how about: Klass.send("find_or_create_by_#{attributes.map{|k,v| k}.join("_and_")}", *attributes.map{|k,v| v}) WARNING: This is a quick solution and could break because I'm relying on the fact that the hash will return in the same order for both calls
