Partially Finish Form_Tag in Ex 8.5

Refactored the views/sessions/new.html.erb file to use form_tag on the signin page.  All tests pass green.  However, submit button looks odd when displayed on browser.  Next step is to troubleshoot coding to determine why and fix.
Finish Exercises 8.5

Refactored signin form to use form_tag instead of form_for.  Still have a problem with the visual appearance of the "Submit" button, but works and tests green.

Added methods to utility functions to decouple tests from implementation.
Fix conflict on X201 to match Github

Not sure if the conflict was properly fixed.  Difference in authentication_pages_spec between the local and remote.  I switched work from local machine to desktop machine, thought that everything was pushed to remote then pulled to desktop.  Not sure how the conflict came up.  Low risk on this branch.

Merge branch 'Exercises-8.5' of github.com:scrodaddy/sample_app into Exercises-8.5

Conflicts:
	spec/requests/authentication_pages_spec.rb
Finish Sxn 9.1.2

Added the edit pagecoding including the edit form and adding 'edit' and 'update' methods to the /users_controller.  All tests passing green but /users_controller still incomplete.

Recommit Section 9.2.e

Fixed deleted lines in the authentication_pages_spec and recommit
Section 9.3.1 Incomplete

Finish 9.3.1 but 1 test in authentication_pages_spec still failing, needs to be fixed.
Merge branch 'updating-users' of github.com:scrodaddy/sample_app into updating-users
Section 9.3.1 with Error

Can't fix following error: "Authentication authorization for non-signed-in users in the Users controller visiting the user index" on the authentication_pages_spec file.

Tested in the browser, and the app does not prevent a non-signed in user from accessing the 'All users' page.  Needs further troubleshooting...
Merge branch 'updating-users' of github.com:scrodaddy/sample_app into updating-users
Finish Section 9.3.1

Completed 9.3.1, but still getting an error for the test:
"Authentication authorization for non-signed-in users in the Users controller visiting the user index" in the authentication_pages_spec file.

Went through code from Ch 8 on, can't find an error.

Note, reverted the sessions/new.html.erb file to the original format using 'form_for' - I had refactored this to the 'form_tag' version in the exercises for Chapter 8.
Finish Section 9.3.3

Success!  Found and fixed errors that were leading to failing tests in previous commits:
- hadn't added :index to the before_filter in the users_controller
- found code that I failed to add in the user_pages_spec, in the pagination section (the before(:all) and after(:all) code for FactoryGirl)
Complete Section 9.4 Deleting Users

Completed through 9.4 with tests all passing green.
Clean up deleted rb.orig file from directory
