With this new traffic, came some new requests for features. The first was a request for a Google Gadget. I didn’t know much about what I needed to create a Gadget, but after looking it up I realized I could use the CatechizeMe API that came automatically when I built the app. With just a few lines of code, the Daily Question service was created and returning JSON data. You gotta love it when things are this easy.

BEFORE:

  def daily_question
    @question = @catechism.daily_question
    render :template => '/questions/show'
  end

AFTER:

  def daily_question
    @question = @catechism.daily_question
    respond_to do |wants|
      wants.html { render :template => '/questions/show' }
      wants.js { render_json @question.to_json }
    end
  end

So now I get a daily catechism question from the CatechizeMe website or via the Google Gadget using JSON:

I am back from RailsConf 2008 and two of my favorite talks were “Microapps for Fun and Profit” by Erik Kastner and “23 Hacks” by Nathaniel Talbott. I have recently been toying around with creating small little apps where I can try out new ideas and sharpen my skills.

One of those apps is the Template Generator Pro. It was a really simple little app the generates funny cover letters, two week notices, job postings, and more. Not a lot to it. What did I learn? I deployed it to SliceHost (my previous apps have been deployed to DreamHost) and starting learning more about hosting and system administration. I also had a chance to port the Nonsense Perl script to a Ruby version. That was fun!

Tools of the Trade

What am I using for my microapps? The first ones (CathechizeMe and TemplateGeneratorPro) were small Rails applications. But that is alot of overhead and not a lot of “micro” in that. So for new things I am looking at Sinatra for a framework and Stone or ActiveRecord with SQLite for persistance. I like JQuery for the Javascript and BluePrint CSS helps me make it look pretty fairly easily. Open Source Web Design and Open Web Design help to stimulate the creative aspects of the designs.

Check it Out

You can see some my little hacks being stored on my GitHub account: http://www.github.com/gdagley. I also have some projects from work at http://www.github.com/relevance.

I love JQuery! I did a short 10-15 minute presentation at the last Dallas.rb to let others in on the joys of using JQuery.

But one thing that doesn’t work right when using JQuery with Rails applications is the JQuery AJAX features and Rails respond_to. It turns out the Rails it looking for a specific request header, but JQuery sends something different one.

It is easily solved with this at the top of your application.js file:

$.ajaxSetup({
  beforeSend: function(xhr) {xhr.setRequestHeader("Accept", "text/javascript");}
});

We are doing lightning talks at this month’s dallas.rb meeting. I decided to give the group some choice of what I would present.

I will do a short one on “Why Firefox Makes Me Look Good” or “Better Web App Development using Firefox and a Buttload of Extensions”

I can also do one “JQuery: I Don’t Know Much, But I Know I Love You ”

And since neither of those are Ruby related, I will throw another one out there: “Tighter Abs: XML Situps Made Easy With Ruby”

I’ll let everyone decide which ones you want to hear more about.

Update

I only did the JQuery presentation and here are the slides (although they were much more interesting in person).

What Extensions I Am Using Right Now

• Web Developer Toolbar – Just about everything you could want to do HTML and CSS, plus I can edit AND save the CSS changes I was playing around with.
• Firebug – So much goodness. Especially debugging JavaScript and looking over AJAX requests and responses.
• View Source Chart – Makes looking at HTML source bearable.
• ColorZilla – a color picker for pulling colors off of web pages.
• HTMLValidator – because it is too easy to miss a closing tag somewhere that messes everything up.
• DummyLipsum – when you need some filler content.
• SeleniumIDE – great little utility for helping to write Selenium tests for functional testing.

Not to mention

• Adblock – no more ads.
• Adblock Filterset.G – no more ads just got easier.
• GTDInbox – for when I think that I am Getting Things Done
• Foxmarks – because I have too many computers and too many bookmarks.

Got a favorite? I’d like to hear about it.

With all of the talk these days of Web 2.0 and the fancy, shiny, draggable, refreshable, blinking, glowing components in web applications, I wonder how many of the will still work when JavaScript is turn off or not even present (yes, it still happens). And how is the usability and accessibility of the application affected when so much of the interaction happens through JavaScript that doesn’t degrade?

I have been taking a look at creating a fully functional application, without any fancy Javascipt or AJAX, and then adding the extra functionality unobtrusively. To force myself to learn how to do this, I stopped using Prototype, script.aculo.us, and the Ruby on Rails helpers with RJS, and I started using JQuery. Two things happened: 1. I started to better understand how AJAX works and can enhance my application. 2. I found out I really like JQuery.

More on my JQuery experiences later. Now back to adding cool features, unobtrusively.

Check back soon for my latest thoughts and ideas. Welcome to the Station, this train is about the leave.
