Rails :action and action request parameter

Hi, all

I’m using DOJO’s tree widget, when I perform a function on the tree it
sends a GET with an “action” parameter and a “data” parameter with JSON
data.

I have a controller called ‘tree’ and if I create a child node on the
tree the request looks like this:

GET /tree?action=createChild&data=[JSON …stuff goes here]

Problem is that Rails overwrites that action parameter with the rails
action.

Is there some way I can tell Rails to assign the ‘action’ request
parameter to :action?
