It makes me wish I could read Spanish, but MeneaRailes appears to be a clone of Digg, but focusing on Ruby on Rails articles (again, mostly in Spanish). It’s only a matter of time before someone makes an English version (I already tried, but I haven’t had the time to get it right, I’m afraid). So.. Spanish readers, enjoy! Read More

A few days ago, Courtenay of Caboose posted an article called ‘pretty tables for ruby objects‘ that give a MySQL-command-line-client style textual view of data stored in your Rails database. The syntax worked like this:

puts Invoice.pretty_table(nil,{:max_width => 50, :line_spacer => ‘-’, :find => { :order => ‘created_at desc’ }})

For an output like so:

| created_at | updated_at | name | due_at | p |

It didn’t make sense to me and I suggested developing a version that worked in this way instead:

Something.find(:all, :conditions => ‘whatever’).pretty_print

This way you can use your regular model accessors and simply use the ‘pretty’ output on any result set whatsoever. Read More

Coda Hale is a Rails developer from Berkeley, CA, who’s developed a ton of useful plugins. I’ll leave the descriptions to Coda:

content_cache

Cache rendered views within the context of your layout, allowing you to mix dynamic content with cached static content.

dollars_and_cents

Stores prices as integers in your database, but access them as floats.

dynamic_session_exp

Allows you to configure Rails to serve up session cookies with expiration dates relative to the current time, instead of some fixed date in the future.

http_caching

Allows your Rails application to take advantage of the caching mechanisms built into HTTP 1.1 (i.e., 304 Not Modified return code). Read More

One of the features of Rails 1.1 was the ability to automatically detect clients that could understand XML and send XML responses to them using the respond_to method. This also works for AJAX requests and HTML, of course. Unfortunately, though, this relies on XML and API clients sending the correct Accept headers in most cases, and, as we all know, users aren’t necessarily so smart (even API users!).

In response to this problem, Edge Rails now accepts the format parameter on the URL, like so: http://www.yourapp.com/post/show/1?format=xml So while the Accept header method still works, you can also pass in the format directly via the URL. Read More
