Getting started: Errors

[SoxFace]

Hi there,

Setting up this repo and I hit a few errors. Thought I'd share them here for good measure as they were quick and easy fixes.

Error 1
undefined method for' for #Devise::ParameterSanitizer:0x007fecfeb4bef8`

so I changed 'for' to 'permit' in registrations_controller.rb based on this suggestion which worked.

Error 2
NameError - undefined local variable or method new_canvas_authentication_path' for #<#Class:0x007fcc624046e8:0x007fcc69eac0d0>
Did you mean? new_admin_canvas_authentication_path:`

so I added 'admin' to the _links.html.erb which worked.

Newbie Error: Email confirmation
Got the app up and running and when signing up, I didn't receive an email. It took me a few minutes til I found it in the terminal #newbie. Then I just copied the href into the browser to confirm the account #bingo

Error 3
When signing out:

ActionController::RoutingError at /users/sign_out uninitialized constant UsersController

Still working on this one and will update once I've worked it out.

Error #1 should be fixed in the latest version:
https://github.com/atomicjolt/lti_starter_app/blob/master/app/controllers/registrations_controller.rb

Error #2 should be fixed as we've removed new_canvas_authentication_path from _links.html.erb

I believe the default configuration is for the app to not send email in developer mode. You can change it in developer.rb by setting the following to true:
config.action_mailer.perform_deliveries = false

You'll also need to configure a mail server.

Error 3 should also be fixed. Use "destroy_user_session_url" to generate the url. Note that we've configured Devise so that it will use a 'get' instead of a 'delete' to sign the user out. We did that so that the client app could easily display a sign out link for the user.
