Chris Hoffman on #335 Deploying to a VPS (pro) 2012-04-03 20:22:08

Thanks Andy, I will try that. I still am wondering if 10.04 LTS is better than 11.10. because I have this extra box lying around. The plan is to set it up and put it in my routers DMZ and then access my test sites from outside my home office. Can't do this with a VirtualBox setup

centaure on #323 Backbone on Rails Part 1 (pro) 2012-04-03 20:22:08

I noticed that I get the same error trace even at 3:45. When I look at the html file being generated, I see that raffler.js is placed before backbone.js. So the raffler script is being loaded before backbone?

Hey Alan,
Thanks for the post. I added the line, but it is still giving the same error trace. I restarted the server and everything. I even started from fresh in another computer (running Ubuntu 11.04). Same problem (I tried both Chrome and Firefox browsers). I am following Ryan's instructions step by step.

Before I spend time digging deep into this, any other help/suggestions will be really appreciated.

Mateus Gomes on #275 How I Test 2012-04-03 18:57:06

Hi Ryan. I was wondering how you test validations. Do you always do it through integration tests (like in the example below) or do you use something else?

          ruby
        
visit new_employee_path
click_button "Save"

page.should have_content "Name can't be blank"
page.should have_content "Age can't be blank"

fill_in "Name", :with => "John Doe"
fill_in "Age", :with => "something"
click_button "Save"

page.should have_content "Age must be a number"
# ...

If you do use integration tests, what's your advice to make the code cleaner/less repetitive?

Thanks for the great screencast!

Andy L on #335 Deploying to a VPS (pro) 2012-04-03 18:17:06

Chris you could set up Vagrant / Virtual box, which would give you the flexibility to test different OS versions.

Yuichi Nakano on #337 Capistrano Recipes (pro) 2012-04-03 17:50:05

Thanks Chris, now things look clear to me:)

Alan Rosin Sikora on #323 Backbone on Rails Part 1 (pro) 2012-04-03 16:09:04

centaure, I had the same problem and figured it out.

Your application.js file must be like this:

          javascript
        
// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// the compiled file.
//
// WARNING: THE FIRST BLANK LINE MARKS THE END OF WHAT'S TO BE PROCESSED, ANY BLANK LINE SHOULD
// GO AFTER THE REQUIRES BELOW.
//
//= require jquery
//= require jquery_ujs
//= require_tree .
//= require underscore
//= require backbone
//
//= require .//raffler
//
//= require_tree ../templates/
//= require_tree .//models
//= require_tree .//collections
//= require_tree .//views
//= require_tree .//routers

And it should be like this:

          javascript
        
// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// the compiled file.
//
// WARNING: THE FIRST BLANK LINE MARKS THE END OF WHAT'S TO BE PROCESSED, ANY BLANK LINE SHOULD
// GO AFTER THE REQUIRES BELOW.
//
//= require jquery
//= require jquery_ujs
//= require underscore
//= require backbone
//
//= require .//raffler
//
//= require_tree ../templates/
//= require_tree .//models
//= require_tree .//collections
//= require_tree .//views
//= require_tree .//routers
//= require_tree .

Notice the //= require_tree . statement, it must be the last one.

By the way Ryan, I'm the newest "pro" member (just registered) and your job is awesome, keep up the great work. And as a suggestion, warn people about this issue, it may save a couple hours.

Hope it helps!

Chris Saylor on #337 Capistrano Recipes (pro) 2012-04-03 15:15:03

You can limit what servers will execute a task by passing a HOSTS environment variable like this:

cap HOSTS=new.server.com deploy:setup

Chris Hoffman on #335 Deploying to a VPS (pro) 2012-04-03 14:33:02

Ryan, Great show. One question though. Why Ubuntu 10.04 LTS and not Ubuntu 11.10? Is there any issues with Ruby or Rails on Ubuntu 11.10? The reason I'm asking is that I was going to try this with a spare machine I have lying around and it currently has 11.10 installed (nothing else). If there are issues then I will just re-roll it with 10.04 LTS

Kevin Whitaker on #320 Jbuilder 2012-04-03 12:16:12

I'm having trouble using Jbuilder with Rails 3.1.0, specifically my Jbuilder view (index.json.builder) is rendering empty, and throwing no errors. I've placed the issue on Stack hoping to get some help:

http://stackoverflow.com/questions/9999395/rails-3-1-jbuilder-rendering-empty-views

Has anyone else seen this behavior?

Stephen St. Martin on #138 I18n (revised) 2012-04-03 11:43:11

you may want to update

          ruby
        
match '*path', to: redirect("/#{I18n.default_locale}/%{path}")

to be something along the lines of

          ruby
        
match '*path', to: redirect({|params, request| "/#{I18n.default_locale}#{request.fullpath}"})

If you want to maintain the request format sent in /posts.json, also it should be noted that a 302 redirect will not resubmit post data, possibly a 307. This method of redirection you need to pay close attention that any urls placed in ajax calls have the locale otherwise there may be some unforeseen bugs, especially with POST requests

centaure on #323 Backbone on Rails Part 1 (pro) 2012-04-03 10:38:10

I don't get the "home page" alert dialogue at 5:35. Note that I did get the "Hello from Backbone" alert at 3:45.

Any help will really be appreciated. I am running rails 3.1.2 in Ubuntu 10.04.

Also note that I had to include the gem "therubyracer" to get the server running at the start (I was facing the issue similar to https://github.com/rails/rails/issues/2963)

Sebastien Grosjean on #138 I18n (revised) 2012-04-03 04:25:04

Nice one, for dealing with locales in the URLs Routing Filter Unless API might be useful.

phrase on #256 I18n Backends 2012-04-03 02:18:02

We think that the very basic i18n approach of rails needs some improvement.
That is why we built a product to handle translations much more easily: phrase

If you have a rails/ruby project that uses the i18n gem, this could be the right thing for you to use.

phrase on #336 Copycopter 2012-04-03 02:15:02

Maybe phrase would be a good replacement for the shut down copycopter.
We are currently in beta for our i18n service application: phrase

If you have a rails/ruby project that uses the i18n gem, this could be the right thing for you to use.

And since we are on Railscasts, we have a screencast, too ;-)

phrase on #138 I18n (revised) 2012-04-03 02:11:02

Managing i18n and l10n can be very painful, especially in large projects with multiple persons working on translations.

That is why we built a product to make things a lot easier: phrase

If you have a rails/ruby project that uses the i18n gem, this could be the right thing for you to use.

Yuichi Nakano on #337 Capistrano Recipes (pro) 2012-04-02 21:58:09

Great episode, thanks Ryan.

One thing, maybe because I'm not familier with Capistrano, I'm curious about what will happen if I run "deploy:install" task twice, for example, in order to add a new server.
I assume Capistrano will try to install everything both to the new one and which has had those already.

If so, will it be OK(no problems as its consequence)? or otherwise is there anyway to avoid it, such like running a task on a specific server?

amul on #323 Backbone on Rails Part 1 (pro) 2012-04-02 17:45:05

to get the value for each entry he used this:

<% for entry in @entries.models: %>
<%= entry.get('name') %>
<% end %>

that didn't work for me, I modified it to this one:

<% for entry in @entries.models: %>
<%= entry.get('entry').name %>
<% end %>

and it works,
Any Idea?, I want the sipler code rather than the code I came up

Thanks

GitHub stopped building gems in October of 2009. They suggest RubyGems.org.

Chris Saylor on #337 Capistrano Recipes (pro) 2012-04-02 16:04:04

Ryan allowed me to Gemify these recipes. Check it out here.

I added a few of my own changes such as setting up a firewall, setting the timezone to UTC and a task for tailing the logs. I plan on adding the Apache, Passenger and MySQL recipes from episode 335 as well.

Andy L on #337 Capistrano Recipes (pro) 2012-04-02 15:40:03

Well I'll answer my own question. :-) I dug into Puppet last week - the tools it has for creating users, installing packages configuring systems etc would take a lot of time to rebuild from scratch in Capistrano. So I've become a Puppet user & believe its worth the time to learn. But this is a complicated tool, and it still seems like there is a need for a simpler deploy tool than Chef or Puppet.

Aldo "xoen" Giambelluca on #256 I18n Backends 2012-04-02 09:14:09

Hi, do you use something like globalize3 for content translation?

I curious about your approach to this problem (e.g. do you build something from scratch or use something almost-ready? How do make the translators work? etc...)

Aldo "xoen" Giambelluca on #138 I18n (revised) 2012-04-02 08:18:08

+1 (x10^99999)

I've just seen the old I18n episode and discovered on of the globalize3 authors (svenfuchs) is even an rails-i18n author. It would be cool an episode about globalize3 (I wonder if some way to build translation interface on it exists...)

Clemens Kofler on #337 Capistrano Recipes (pro) 2012-03-31 10:15:10

A little note: Instead of using the set_default method here (or Capistrano's own _cset), a similar effect can be achieved by using the second parameter to the fetch method like so:

          ruby
        
directories_to_create = fetch(:directories_to_create, [])

If I now use set(:directories_to_create, Dir[...]) that gets used, otherwise it uses the second parameter as the default (in this case just an empty array).

Michael van Rooijen on #335 Deploying to a VPS (pro) 2012-03-31 10:04:10

Heroku is good in a lot of situations. However, what disappoints me a little is the lack of JRuby and Rubinius support. This is where EngineYard shines a little more. A lot of Ruby developers probably aren't aware how much more concurrency you can gain using a VPS running JRuby/Rubinius with Puma/Trinidad/TorqueBox rather than running Thin or Unicorn.

For example, TorqueBox (a JRuby-specific App Server) is a "real" application server that runs independently (it's practically a whole infrastructure, not something that just binds to a port), and you deploy your application to this app server. This one single instance uses threads (JVM, not MRI) for everything you would normally have to spin up processes for with MRI (which translates to Dynos on Heroku).

There have been people that took their worker farm (120 worker processes) from around 60gb in memory usage (yes, 60 gigabyte) spread across like 10 dedicated servers, down to about 1gb memory usage on a single server by switching from process-based scaling to thread-based with JRuby or Rubinius. That is huge. Not only does it scale well, you reduce a lot of costs, the infrastructure becomes more simple and imagine running 120 workers on Heroku, the bill goes through the roof. It really makes me wonder why there aren't more people supporting JRuby and Rubinius. (Note that this also applies to concurrent web requests of course, not just workers).

However, I definitely agree you when it comes to being more at ease when deploying to Heroku, simply because you cannot do any administrative tasks. When something breaks, needs updating, and what not, Heroku is the one taking care of it all while you sleep. It mainly depends on your application's requirements. If you have a basic app that doesn't really need a lot of concurrency (be it in the web process, or worker process) then it's all good. However, once you have use cases where you run large worker farms or tremendous amounts of traffic, it might change your game completely.

These are all interesting discussions, I guess basically it comes down to picking the right tools for the job and dealing with certain tradeoffs on each side. But it'd be good to let everyone know it's not just MRI, Thin and Unicorn out there.

What'd I'd love to see from Heroku is (real) support for JRuby (now) and Rubinius (once RBX hits 2.0), perhaps 1GB of ram per Dyno (at a higher price) and the ability to use TorqueBox flawlessly. I think this would be a total game changer for deployments and power per Dyno.

tl;dr:

Check out Ruby Implementations:
- JRuby
- Rubinius
Check out thread-enabled app servers:
- Puma
- Trinidad
- TorqueBox (this is pretty much one-of-a-kind, a beast, not comparable to any other Ruby app server to date)
@Heroku: Please add real support for JRuby and TorqueBox.

Peter Liu on #334 Compass & CSS Sprites 2012-03-31 08:59:08

I like Twitter Bootstrap because it has same nice CCS features and javascript features like pophover, drop down menus, etc. I suppose one can use jQuery to achieve that but Twitter Bootstrap makes it really nice. My only compliant is that it uses LESS instead of SASS.

Back to Compass, can one have BOTH Compass and Twitter Bootstrap? I would like to have the dynamic nature scaling for mobile devices while having the mixing of Compass.

Depends on the problem. But in general yeah you should be looking at the logs. There is the server log and also production logs. I don't think you want to be looking at the development log when in a production environment.

Hi! Please help!
I am stuck on this error:

Hi Carl, gummybears - thx for help.

In the end I found the solution for installing mysql by sending the password via capistrano when the blue screen appears- its quite simple. Here is the solution:

          ruby
        
# capistrano task for installing mysql
run "#{sudo} apt-get -y install mysql-server" do |channel, stream, data|
  # prompts for mysql root password (when blue screen appears)
  channel.send_data("#{mysql_root_password}\n\r") if data =~ /password/
end

Also, for those that are interested - user creation can also be automated via capistrano (that is the only thing Ryan did manually in this episode). You can check that at this link.
It's a bit complicated, but in the end you don't even have to ssh to machine prior to running capistrano recipes.

I hope this is useful to someone :)

Edit: Executing the command on the server without Capistrano seems to work. :/

Great screencast :)

But I ran into a problem when Capistrano tries to build my assets. I have no idea what's going on, if I start rails locally, everything works fine!

          log

But in my Gemfile I have bccrypt-ruby set up.

          Gemfile
        
gem 'bcrypt-ruby', :require => "bcrypt"

I have the same issue, couldn't resolve it.
So I ran the command manually and commented it out.

I can't seem to figure this out at this moment in time. I created a new application from scratch, added a view, copied a template for the application.html.erb to contain a navbar. When you make your window smaller than 800px so the menu merges into a pulldown, you are unable to open the navbar. I uploaded the application if someone can look at it.
