Problem with generating a scaffold for odot application

So I'm on the the 'generate a scaffold video and I'm following along at migrating the database at 2:50.

when I followed along with the command and did 'rake db:migrate' I get an error (I didn't include the bin before rake as It doesn't rocognize bis as a command for me, just for the sake of being thorough I did include the command with bin and didn't work)

For the error first it says

createtodolists: migrating create_table(:todo_lists)

just like the video says. THen it says

rake aborted! StandardError: An error has occurred, this and all later migrations canceled:

privare method 'test' called for(then it says some stuff about active record, the db migrate and the locations for createing the todo lists ) then it says 'block in change'

then it gives the location of the 'creating a todo list' command again and says 'change'

and then it says

C: in 'migrate' tasks: TOP => db:migrate (See full trace by running task with --trace)

I really have no clue how to fix it. Any and all help appreciated. Thank you in advance.

P.S I used bitnami to set up an all in one ruby environment so could it be that in the case of the ruby environment that bitnami set up that I don't need to migrate the database?
