tinyMCE.activeEditor.getContent()

For example, to send a form and populate a preview div with the response.

$('content_form').request({
  parameters: { 'preview': "1" }, // overrides parameters
  onComplete: function(transport){ 
    $('previewContent').update(transport.responseText); 
  }
});

In Webkit you can use the HTML5-attribute autofocus:

= form.text_field :title, :autofocus => 'autofocus'

Here is a jQuery fallback for browsers that don't speak HTML5:

var Autofocus = {

  supported: function() {
    return 'autofocus' in document.createElement('input');
  },

  fake: function() {
    $('[autofocus]').focus();
  },

  extend: function() {
    Autofocus.supported() || Autofocus.fake();
  }

};

$(Autofocus.extend);

Most of these will not work in newer projects because these use the Capybara/Rack::Test combo in lieu of Webrat.

Find input fields

Then /^there should be a "([^"]+)" field$/ do |name|
  lambda { webrat.current_scope.send(:locate_field, name) }.should_not raise_error(Webrat::NotFoundError)
end

Then /^there should be no "([^"]+)" field$/ do |name|
  lambda { webrat.current_scope.send(:locate_field, name) }.should raise_error(Webrat::NotFoundError)
end

Find html content

Then /^I should see "([^\"]*)...

With defaults, RCov doesn't work the way you how you would like it to. To create a nice test coverage report, copy the attached file to lib/tasks/rcov.rake. After that rake rcov:all will run all RSpec examples and Cucumber features. The report will be written RAILS_ROOT/coverage/index.html.

Here is what the task does in detail:

• Generates aggregated coverage of both RSpec and Cucumber
• Works with Rails 2 and Rails 3
• Reports for app/**/*.rb and nothing else
• If called with an environment variable IGNORE_SHARED_TRAITS=true it ...

To parse XML-documents, I recommend the gem nokogiri.

A few hints:

• xml = Nokogiri::XML("<list><item>foo</item><item>bar</item></list>") parses an xml string. You can also call Nokogiri::HTML to be more liberal about accepting invalid XML.
• xml / 'list item' returns all matching nodes; list item is used like a CSS selector
• xml / './/list/item' also returns all matching nodes, but .//list/item is now an XPath selector
  • XPath seems to be triggered by a leading ....

How it works

See the lemonade descriptions.

Unfortunately, the gem has a few problems:

• it does not work with Sass2
• it always generates all sprites when the sass file changes, which is too slow for big projects
• it expects a folder structure quite different to our usual

All these problems are solved for us, in our own lemonade fork. This fork has since been merged to the original gem, maybe we can use t...

This is about converting Haml to ERB and not the other way round which you probably want!

This process can not be automated 100%, but you can still save time.

First do

script/plugin install http://github.com/cgoddard/haml2erb.git

Then in the console type

hamls = Dir["app/views/**/*.haml"] - ['app/views/layouts/screen.html.haml'];
hamls.each do |haml| 
  puts haml
  erb = haml.sub(/\.haml$/, '.erb')
  File.open(erb, 'w') do |file| 
    file.write Haml2Erb.convert(File.read(haml)) 
  end
end

After th...

Gem to provide nice looking urls ("/blog/the-greatest-bug-i-never-fixed"). If you don't need anything too special (like i18n for the urls) it works as a drop-in-replacement. It basically overwrites #to_param to return the slug, and .find to search by the slug.

Make sure, everywhere you build paths, you use model_path(:id => model) instead of model_path(:id => model.id). You also need to adapt all code using something like .find_by_id. The regular .find is fine.

See the github README for installation instructions.

Given a list of acceptable elements and attributes, Sanitize will remove all unacceptable HTML from a string.

I've seen this granularity problem on every project, product or program I've worked on. Often in non-agile methods it comes it up in the form of traceability requirements on top of the actual requirements.

LaterDude is a small calendar helper with i18n support

The argument that using tests is a ideologic waster of time fails when one considers how it can help to insure architectural decisions.

i keep looking for ways to help people 'get' REST. not URLs or HTTP Methods; but REST itself - in a nutshell. so here's a new angle i've started playing with: "REST Upside Down."

Until some future version of HTML gives us new native controls to use in a browser, at Google, we’ve been playing and experimenting with controls we call “custom buttons” in our apps (among other custom controls).

Pocket Informant for the iPhone doesn't just simply let you view your daily events but lets you really work with them. So many calendar or task applications are either too hard to use or too simple to be useful. Pocket Informant takes eight years of mobile experience and brings a fresh perspective to the iPhone user.

I just finished reviewing Rails 2.3 Nested Object Forms. While a very nice and “magical” feature, I’ve got to admit that I’m really not that crazy about how it works.

Rails’ script/console makes it easy to fetch, view and edit your database records. But can you edit those records as quickly as you edit code in your text editor? Riiight, like editing our database records in an editor is gonna happen? It already has.

Hirb provides a mini view framework for console applications, designed with irb in mind.
