Rails - Oct 2006 - problem passing parameters to a shared template from controller

I am using a shared template from within another template AND also using the
same from a controller action.
It works fine when called from the template BUT when called from the
controller the parameter is not passed in from the controller.

the controller action is -

def update
    @picture = Picture.find(params[:id])
    render(:template=>"shared/trip", "image" =>
@picture)
end

and the shared template is - trip.rhtml

<div class="plank">
    <img src=/images/myimages/<%= image.file_name -%>
width="80" height="60"
>
</div>

The template is invoked but the image variable within the template is nil.
...........
You have a nil object when you didn''t expect it!
The error occured while evaluating nil.file_name
.........

Thanks

I tried further..

So it works if I set a attribute before calling from the controller action.

def update
    @picture = Picture.find(params[:id])
    *@image = @picture
*    render :template=>"shared/trip"
end

The problem now is that the same shared template is called from another
template

<%= render "shared/trip", { "image"=>image_pp } %>

now inside trip.rhtm (the shared template) I have access to image by @image
(attribute) if called from controller and by simple argument "image"
(no
@) if called from another template.

Is there no way to pass a variable just like I do from a template?

Thanks in advance.

I don''t like $_,  actually the only place I like $s is in my wallet.
