With nested routes, I find I create a lot of controller methods like:

   1  
   2  def load_user
   3    @user = User.find(params[:user_id]) if params[:user_id]

Here's a TextMate snippet, so you can just type: defmodel, TAB, user, TAB, and you're done.

Snippet:

   1  
   2  def load_${1:model}
   3  	@$1 = ${1/[[:alpha:]]+|(_)/(?1::\u$0)/g}.find(params[${2::$1_}id])${3: if params[:$1_id]}
   4  end

Activation: defmodel
Scope: source.ruby.rails

I have this in the Ruby on Rails bundle, but you can put it anywhere. Its the scope that is important.

When using mysql for rails apps, you may need a

   1  socket:

value. I can never remember mine. So I added a TextMate snippet to find it. (read below for non-TextMate)

Snippet text:

   1  
   2  socket: `mysql_config --socket`

Activation:

   1  socket:

Scope selector:

   1  source.yaml - string

<h3>Usage:</h2>

In your database.yml, go to the line

   1  socket: 

, delete any blank spaces til the cursor is at the colon, then press TAB and wait. The line will be updated with the socket location.


<h3>Non-TextMate</h3>

If you don't have textmate, you can get your socket location using:

   1  
   2  mysql_config --socket

And paste the result into your database.yml
