Does anybody have any guesses about why this is happening? Specifically,  
why it is trying to call the id as an action in the second attempt:

### Attempt One

\<%= link\_to\_remote(image\_tag(‘button\_details.gif’, :id =\> “details”),  
:update =\> “results”, :url =\> {:controller =\> “masters”, :action =\>  
“show”})  
%\>

### Attempt One Console

Parameters: {“action”=\>“show”, “controller”=\>“masters”}  
ActiveRecord::RecordNotFound (Couldn’t find Master without an ID)

OK, this makes sense. I just need to pass along an ID…

### Attempt Two

\<%= link\_to\_remote(image\_tag(‘button\_details.gif’, :id =\> “details”),  
:update =\> “results”, :url =\> {:controller =\> “masters”, :action =\>  
“show”, :id =\> contact.id}) %\>

### Attempt Two Console

Parameters: {“action”=\>“4”, “controller”=\>“masters”}  
ActionController::UnknownAction (No action responded to 4):

### Controller

def show

```
user = User.find(current_user.id)
@master = user.masters.find(params[:id])

respond_to do |format|
  format.html # show.html.erb
  format.xml { render :xml => @master }
end

```

end

Your image\_tag javascript generator is messing up your link\_to\_remote  
javascript helper.

My guess is that you want to perform a link to remote when the image is  
clicked… In which case, I think you should just use an image tag with a  
javascript onClick() handler instead of the javascript generators

Ilan,

Thanks for the tip. I went ahead and stripped out the image tag and  
replaced it just with the standard text link…

\<%= link\_to\_remote “Details”, :id =\> “details”), :update =\> “results”,  
:url =\> {:controller =\> “masters”, :action =\> “show”, :id =\>  
contact.id} %\>

but it’s still having the same complication.

☹
