Capybara assert dropdown having a desired value selected not working

Question

$ruby --version
ruby 1.9.3dev (2011-09-23 revision 33323) [i686-linux]

gem 'rails', '3.2.9'

group :test do
  gem 'cucumber-rails', require: false
  gem 'capybara', '~> 2.0.3'
  gem 'rspec-rails'
  gem 'database_cleaner'
  gem 'factory_girl'
  gem "ffaker"
  gem "capybara-firebug", "~> 1.3.0"
  gem 'ruby-debug19'
end

In one of my Cucumber Step I am trying to assert that a drop-down element (<select> tag) has a particular option selected using Capybara API with the following code.

  within('#myForm') do
    page.has_select?("#event_type", selected: @event_type).should be_true
  end

However I am getting this error:

   expected: true value
   got: false (RSpec::Expectations::ExpectationNotMetError)

I inspected the DOM using @firebug tag of (capybara-firebug) on my scenario and found that the desired option (held by @event_type) is getting selected in the drop-down however in the DOM the "selected" attribute is not getting added to the select tag which I guess is causing the expectation to fail.

I found a similar reference here: https://github.com/jnicklas/capybara/issues/171 which mentions about the commit having the fix but I guess the commit is not merged to the capybara version I am using.I trying digging in the source code and found that the fixes mentioned at https://github.com/jnicklas/capybara/issues/171 are not present in the Capybara's codebase.

Can any body please let me know how to assert that a select tag has a particular option selected?

Note: When using capybara in my Gem file without any version:

gem 'capybara'

Capybara Version 2.1.0 is initiated to be installed however it fails with error:

capybara requires Ruby version >= 1.9.3

though I have the required ruby version.

I don't use cucumber, but in you example

within('#myForm') do
  page.has_select?("#event_type", selected: @event_type).should be_true
end

it depends on your dom, but you don't have to use '#' in the id selector here, and 'selected:' should be the text in the option, not the value.

so it should be (assuming @event_type is what you are displaying for the text)

within('#myForm') do
  page.has_select?("event_type", selected: @event_type).should be_true
end

or i'd prefer

page.should have_select('event_type', selected: @event_type)
