Hi,

I am using Ext Grid to draw a table.

show.rhtml page allows to access account data so the url look like  
http://\<server\_name\>/\<project\_name\>/show/1, where 1 is an account id.

show.rhtml has the following code:

\<%= javascript\_include\_tag “grid.js” %\>

grid.js is used for grid initialization and rendering it accesses the  
“\<project\_name\>/grid\_data” method that is in the project controller

grid\_data forms the jsondata for the grid.

The problem: grid.js has no idea for what account the grid is  
rendered. However, account id is required in grid\_data to provide a  
proper json data. How do I pass account id from “show.rhtml” to  
“grid.js”?

Thanks for your help.
