Boolean Columns
Just found this little tidbit about returning a boolean from a tinyint column tonight on the rails wiki...
Columns which are either boolean or tinyint(1) are recognised as booleans by ActiveRecord. So, if you have a table “people” and a column “rocks tinyint(1)”, you can say:
person = People.find(1)
person.rocks = trueHowever, person.rocks will return an integer, and Ruby thinks that 0 is true. If you want to test for truth, use person.rocks?, like this view example:
<% if person.rocks? %>
You rock, dude!
<% end %>I did not know that. Pretty dang cool.

Go ahead, cheat (It's ok!)
Though I'm fairly weened from intellisense from my .NET days, I still find myself always needing some type of reference when writing Ruby or Rails projects. There's always a browser tab with the Rails API, noobkit, or some other cheatsheet . While cheatsheets are pretty and all, they are sometimes just a hassle to find and go it when you just need that little syntax helper. So what do I do, I cheat.
This little command line tool provides a wealth of help at the tip of your fingertips.
gem install cheatThen see what cheats are available.
cheat sheetsOr just run one (I use this one a lot)
cheat strftimeThere are just hundreds out there. And you can edit (fix) one or add your own. The app is just a command line front end to a wiki. Pretty sweet.

Saving CSS Background Images
The good ‘ole `Save Page As` drops the ball when trying to grab well-formed, standards based websites where most, if not all, of the images are specified in CSS. I spent an hour or so yesterday scouring the web for some tool that would download these CSS images. I found nothing.
I went back to the tried and true Web Developer toolbar extension for FireFox and found the View Image Information option (under the Images button).
It interrogates the CSS file creates a very nice list of all inline and CSS images. You still have to right click and save them individually, but it definitely helps.
