Subversion Cheat Sheet 1.0!

February 23rd, 2007

I’ve noticed a huge interest in my Subversion articles lately and I thought to create a nice cheat sheet for all you.

The cheat sheets includes common commands that you’ll use when using Subversion on a daily basis. I didn’t include every option or command that subversion supports, nor did I include any administration stuff. This sheet is aimed at developers who use Subversion on a daily basis.

RoR: link_to_remote with a text_field value as an argument

February 21st, 2007

Forms are very well supported in Ruby on Rails. But in some cases you want to get information about a value a user has entered in a form, but without submitting the entire form. A good example of this is the sign up procedure at Yahoo. You enter your desired username, click “check availability” and you know if the name is available to you.

In my case I want to add locations to my database and use geocoding to get latituden/longitude values. So, I want users to enter an address and click “check” to verify that geocoding is successful. When successful, the full address and lat/lng values are automatically filled out in the form.

This article shows you how to update those text fields and most importantly, it shows how to add a text_field value as a paramater to your link_to_remote tag.
