Ruby on Rails

Hi YogiZoli,

Thanks for your post.

I think you meant has_one instead of 'has_many' (in your first bullet
point for student.rb).
I tried what you suggested, and my routes.rb file has
resource :accounts

I also went back to my original "form_for" text as per my attachment and
I no longer see that NoMethodError (YAY!) that I first posted up.

I figured out why (at least i think i did) my 'insert into accounts'
would delete when I rendered the show.html.erb file after creating an
account.... I had the text ":dependent => :destroy" in the model.rb file

I've updated my models to have that 1-1 relationship.
While I was testing it out, I noticed the following in my server logs...

*****************

After entering the account details I make it redirect to the
app/views/student/show.html.erb view because I basically want to just
update the "show" page. BUT I can see that the student_id is being
updated to NULL - why is that?
