(upbeat music)…- [Instructor] I hope that you were able to complete…the challenge assignment for the multi-list maker.…In this movie, I'm going to show you the solution…that I came up with.…Now you shouldn't have needed to make any changes…to init.rb, controller.rb, or list.rb.…I had done all of that work for you already.…List_dir.rb though is where…you needed to fill in some blanks.…And let's start with that initialize method.…So the first step is to check and see…if the directory exists, and if it doesn't,…then to create it.…
If it does exist, we want to make sure…it's readable and writeable.…So it works very similar to what we were doing…in list_file.rb, you could use that as a template…for a lot of it, go down the list,…and then just change a few things.…So we're going to set the directory path…by using the file join with APP_ROOT…and the directory name, we got that from up here, dirname.…And then I'm going to check and see,…dir.exist to see if it exists.…If it does exist, I'm going to check and see…if it's readable and writeable.…
