Assigning a custom layout for certian action in Rails3

dano — Sat, 04 Sep 2010 04:36:26 +0000

If you want to assign different layout for certain action, the code below will help.

def action1
  render :layout => "new_layout"
end

Then create a new layout in the app/view/layouts/new_layout.html.erb and that’s it. I used this for the popup window which required a different layout with main default layout.

Hope it helps!

Log rotation in Rails 3

Hi,

I need to rotate my log in development machine since it grows to over 80 MB. So with some googling I found two useful links:

Who said size is not important?

Log rotation in Rails apps

But neither of them worked for me. So with spending more time in googling and try-and-error, I got this solution. Put the code below in your config/application.rb

config.logger = Logger.new(config.paths.log.first, 50, 1048576)

Hope it helps.

My environment is Ruby 1.9.2dev / Rails 3.0.0.rc

Vmware Fusion crashes in Macbook Air

Oh, my Lord. You gave me Macbook Air one night and now why are you taking it away from me?

Macbook Air brought me not only joy but also disatrous nights. How come?

Well, it’s not Apple’s fault. It’s VMware’s!!

I installed Windows XP using boot camp and tried to use it with Vmware Fusion. Just natural desire and a must for everyone!! But it didn’t happen as I expected. VMware had kept crashing and I did everything I could imagin, but without success. Why not?

The answer is, Macbook Air doesn’t have a Super drive and VMware just crashes when it starts to run boot camp partition and can’t find a CD/DVD drive. Duh? But you can easily fix it by going to VM settings and disconnecting the CD/DVD drive. It works like a charm. If you want to know more about it, please refer to this thread. FYI, Parallel works just fine.

Recently, VMware Fusion team opened their team blog but I couldn’t find any information regarding this issue there. But I could find their marketing posts ( 1, 2 ) regarding Macbook Air and Fusion. I think that information like this remedy, not marketing materials, should be published in the blog until the official fix comes out. I spent several hours in googling to find out the solution to this issue and it was not pleasant or efficient.

Hey, Team Fusion guys, please post more valuable information for your precious users. I paid for your service and I don’t want to debug your product and googling for the fix. Please do it for me, it’s your job!! Thanks in advance.
