I assume the above code is in a CONTROLLER. If so, you should stick to the
controller actions index, new, create, edit, update, and show. Avoid creating a
controller action with another name.
You didn't show us the VIEW. In the VIEW, does the form you are submitting
contain a user_id ? If not, that is why you don't have a user_id in your notes
record.
If this note is supposed to be associated to the currently logged in user,
you'll want to add
before_filter authenticate_user!
to the top of your controller, and also in your create method do something like
this:
current_user.notes.create(lesson_params)
You will find this documented in the section marked "has_many Association
Reference" on this page:
http://guides.rubyonrails.org/association_basics.html#has-many-association-reference
(By the way, the current_user method itself comes from devise, which
documentation you should thoroughly read here:
https://github.com/plataformatec/devise)
Finally, get yourself RubyMine and learn how to use the Go-To-Declaration
(Command-B). Do that NOW before you go any further. (Another IDE is acceptable
too if it has Go-To-Declaration functionality)
