Rails 3.1 smtp gmail Errno::ECONNREFUSED Connection refused

October 9, 2011

This post was originally published in the Rambling Labs Blog on October 9, 2011.

I was trying out the rails 3.1 smtp mailer on the sandbox application I use to test all the new stuff and it was throwing this error:

Errno::ECONNREFUSED in TestController#create

Connection refused - connect(2)

And I had this configuration on config/environments/development.rb:

Demo::Application.configure do
  # ...
  config.action_mailer.delivery_method :smtp
  config.action_mailer.smtp_settings = {
    enable_starttls_auto: true,
    address: 'smtp.gmail.com',
    port: 587,
    domain: 'gmail.com',
    authentication: 'plain',
    user_name: '<email@yourdomain.com>',
    password: '<password>'
  }
  # ...
end

I tried quite a number of combinations for…

Updating and/or uninstalling all installed gems

October 8, 2011

This post was originally published in the Rambling Labs Blog on October 8, 2011.

I like to have an rvm gemset (see more about rvm) with the latest versions of all gems and I usually use this as my sandbox for testing out the latest features and issues of the gems. To update one gem to it’s latest stable version, you just have to run this:
```
gem update GEMNAME
```
The only problem is that for updating every gem you have installed, you have to remember each and every gem you have installed to pass it to the command… Nah, I’m just kidding. Just run the following command, and you’ll be fine:
```
gem update `gem list | cut -d ' ' -f 1`
```
UPDATE

To uninstall all installed gems, it’s the same command with uninstall instead of update, like this:
```
gem…

Rails 3.1 "rake db:migrate" fails with "stack level too deep" error

September 20, 2011

This post was originally published in the Rambling Labs Blog on September 20, 2011.

I was trying to run the following command on a new rails 3.1 app and it was failing… badly.

Rails 3.1 "rails server" error Could not find a JavaScript runtime

September 19, 2011

This post was originally published in the Rambling Labs Blog on September 19, 2011.

I upgraded to rails 3.1.0 and created a new ‘test_app’.
```
rails new test_app
```
Got into the directory. Everything was fine, until I tried to run:
```
rails server
```
It threw a weird error:
```
Could not find a JavaScript runtime.
See https://github.com/sstephenson/execjs for a list of available runtimes.
```
That’s kinda weird. What does a rails app have to do with any JavaScript runtime? I guess it’s support for something that I still don’t know anything about.

I googled that and found a stackoverflow question. So, two solutions for the issue: either*** install nodejs*** or include “gem ‘execjs’” and “gem ‘therubyracer’” in the Gemfile and run bundle install.

Pick…

RubyMine vs. Vim: my point of view

September 18, 2011

This post was originally published in the Rambling Labs Blog on September 18, 2011.

So, I tweeted a question earlier today about what editor is preferred by the rubyists and, although I didn’t get many answers, it, combined with a recent discussion I had about RubyMine vs. Vim later, helped me clear my reasoning a bit.

By my reading of Agile Web Development With Rails and some people I follow on twitter, it seems that all the cool geeks use Vim (or TextMate or Emacs) for Ruby and Ruby on Rails programming instead of any IDE.

I once googled to find out that vim was way complicated to set up. That same time, I found akitaonrails vimfiles on github. Fairly easy to set up if you just follow the instructions. But today I realized that there…
