I started out with a normal scaffold for the USERS table. I changed
the index view to be list.html.erb but the url: ‘/users/list’ returns
an ‘unknown action’ error. ‘/users/list/:id’ also returns an ‘unknown
action’ error. I’ve also merged both the edit and new views into the
manage.html.erb which duplicates the list view except with a form on
the right side. the url ‘/users/manage’ returns an ‘unknown action’
error but ‘/users/manage/:id’ brings me to the manage page with the
edit form.
in my routes.rb, it reads:
map.resources :users
The update an delete actions work but they don’t route me to the right
url. the new action does not work. can anyone help? I’ve pasted my
controller and views below.
