Hi, I seem to be having a problem with Ajax.Updater passing variables  
correctly. I have a Ajax call that does this:

\<%= link\_to item.name, {:action =\> “#”}, {“onmouseover” =\> “new  
Ajax.Updater(‘display\_stuff’, ‘display’, {parameters:‘client=IBM’})”} %\>

My ‘display’ action only has one line:

def display  
@client = params[:client]  
end

Looking at the log, the variable seems to have been passed correctly:

Processing DisplayController#display (for 127.0.0.1 at 2007-07-29  
22:58:06) [GET]  
Session ID: a724b690db0cfe794dd1c3821cbf0919  
Parameters: {“client”=\>“IBM”, “action”=\>“display”,  
“controller”=\>“display”}

Any idea, anyone?

Hi,

you havn’t said what it isn’t doing.

> From the info you provide, @client should be taking on the value of  
> ‘IBM’. But you are doing nothing with that in the controller. If  
> your view is displaying the client then you will need to look up the  
> client IBM from your database using a suitable find operation. Now

> \<%= debug @client %\> into your template.
