Posted in Deploy Ubuntu 14.04 Trusty Tahr Discussion

Send a copy of your config to me at chris@gorails.com and I'll see if I can help!

Posted in Deploy Ubuntu 14.04 Trusty Tahr Discussion

The first one. It's saying it can't ssh into domain.com as the deploy user. When you ssh in manually with ssh deploy@domain.com that should connect without asking you for a password. That works correctly?

forward_agent is mainly just used when it checks out your code from Github or the like. It will use the key you deploy with to talk to github instead of a key on the server.

Posted in Deploy Ubuntu 14.04 Trusty Tahr Discussion

Don't specify the keys option there. Your local key in ~/.ssh/id_rsa will be tried against the server's /home/deploy/authorized_keys file. Capistrano won't allow password authentication, so you must make sure you ran the ssh-copy-id to add your pub key to the server deploy user's authorized_keys file.

Posted in Pagination with will_paginate Discussion

You could probably do something like this in your controller:

@posts = Post.paginate(page: params[:page])
redirect_to root_path if @posts.empty?

Posted in Deploy Ubuntu 14.04 Trusty Tahr Discussion

Yeah, when it says authentication failed, it means it couldn't connect over SSH. You'll need to tweak your deploy config to make sure it matches your SSH configuration.

Posted in Deploy Ubuntu 14.04 Trusty Tahr Discussion

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

Posted in Deploy Ubuntu 14.04 Trusty Tahr Discussion

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

Posted in Authorization With CanCanCan Discussion

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.

Posted in Button Loading Animations with jQuery UJS Discussion

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

Posted in A Look Into Routing Discussion

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

Posted in Deploy Ubuntu 12.04 Precise Pangolin Discussion

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. :)

Posted in Deploy Ubuntu 14.04 Trusty Tahr Discussion

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! :)

Posted in User Authentication with Devise | GoRails

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.

Posted in jQuery UJS Callbacks Discussion

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?
