Absolutely! I'll probably plan on covering this in a screencast or a separate tutorial.

Oh hey, good find. I'll be sure to update that soon.

I'm covering Pundit next, but CanCan is by far the leader with 4 million downloads. CanCanCan is the community maintained version of cancan so it is still always up-to-date. I'm going to do a few authorization approaches in a row so we can compare them side by side and you can determine which works the best for you.

The package names have probably changed a bit. You may want to switch to the 13.04 version as it probably has some more similar package versions.

That's interesting. Do you get any errors in the console that show the browser having trouble loading the icon font by chance?

Yes! I forgot to mention that. Thanks for sharing. :)

Great post Nick. That will be useful for anyone running into trouble with rvm. I'll be sure to point people that direction if they have issues. :)

Depends on what you want to do, but generally Passenger is quite good on all fronts. You can read some more about some performance testing but no matter what, it isn't going to be definitive that one is always better than another. https://blog.engineyard.com...

That would be a problem with your nginx config. The IP address doesn't matter, it's okay to serve up on that instead of a domain. You may have changed the config and not restarted nginx or you did and it was invalid and nginx didn't actually load it. Double check that and the /var/log/nginx/error.log file to see if you have anything wrong there.

Thanks David! :)

Plenty of cases, but most of those revolve around building out a very custom onboarding flow. Most of the time (including OAuth) is handled well enough with Devise.

Hey Vlad and biodiscover, that's totally fair. There are people who have asked to pay and want to support the site. I understand you're not sold yet and there's nothing wrong with that. Everyone's at a different stage in their career, so some people have gotten some valuable insights out of the screencasts so far and other people are further along that they haven't. I'm working my way towards the more advanced content. Hopefully over time I'll be able to earn your support as well! :)

It seems to be a bug in the new readline dependency. I *think* if you're on the latest patch version of 2.0.0 (p481) that it has a patch for that bug.

Ah I see now. So the stripe button JS takes an amount simply to display the amount. On the backend, you are always submitting charge for the same amount which is why you're seeing that problem.

To solve this, you want to define some "plans" and submit that to the create action along with the stripe card token. You can do that in hidden fields, but you want to do that instead of submitting the amount so users can't submit their own amount which would be a security issue. If you send over the plan name and look up the amount (you can hardcode this into your app), then you can calculate the appropriate price. Does that make more sense?

That command is provided by ruby-build. Make sure you didn't miss any of those steps.

That's generally not something you would want to do unless you are talking about AJAX. What are you trying to accomplish?

Thanks John. That *should* be fixed in Ruby 2.1.2. Is that what you were installing?

It works fine in Rails 4. From what I can tell, those find_by_COLUMN methods didn't go away, but the ones listed in the README here did: https://github.com/rails/ac...

Sounds like you don't have postgres running. Follow the steps in the postgres section again to make sure you got them (especially the launchctl one.)

Change your config/database.yml to look like this:

development:
  adapter: postgresql
  host: 127.0.0.1
  database: myapp_dev
  username: YOUR_POSTGRES_USER

Rename the database to whatever you want to call your app's database and also make sure to change your postgres username to your username. And last, but not least, make sure postgres is running.
