Ruby on Rails problems & solutions - Apr 8, 2011

RSpec view debugging hackI needed to see what the rendered view looked like, so I could figure out why it was finding “1151” instead of “1” in a tr>td selector.  I knew how to do this in RSpec 1, but not in RSpec 2.

Not a web reference solution to this one, I found it in the RSpec book.  If you are using RSpec, I can’t imagine why you wouldn’t want to buy this book.

The answer is “rendered”.  As in:

render

puts rendered.inspect

Not pretty, but it works.  Yes, I know… debugging by println (I’m aging myself with that, aren’t I?).  Sometimes the “not pretty” way is the quickest, though.

RSpec’ing with acl9

I was using acl9 ( https://github.com/be9/acl9) in my Rails 3 project.  Now, I have specs for the acl9 functionality, but I started bumping into it on all my controller specs, and I wanted to skip it.  Again, I have this working in my old Rails 2.x app, and RSpec 1.x, this is the new and improved way, with some specific gotchas for acl9:

Password change dialog

Finally got around to implementing that password change story (That’s right, suckers, you CAN launch without something that seems really basic).  Sometimes, you find really old stuff:

Take the old stuff with a grain of salt, because it may be total junk.  OTOH, it may still be the definitive answer.  But I kept looking, and found this:

http://www.justinbritten.com/work/2008/03/how-to-change-or-reset-your-password-with-restful_authentication/

which I liked a lot better, from a purist, RESTful point of view.  However, since I am using authlogic, it couldn’t be that simple, could it?  So…

Relevant code bit:

@current_user.valid_password? params[:old_password]
