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

width="80" height="60" >

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.
