I think routes are messing up data that I am trying to pass between  
showing  
a product and entering a review.

In the product/show view I have:

\<%= link\_to ‘Add a Review’, new\_review\_path, :xyz =\> @product.id %\>

Inspecting the params of review/new there is nothing but  
{“action”=\>“new”,  
“controller”=\>“reviews”}

–

Then again, I could be way off in the original link\_to statement.

The code is pretty much stock stuff.

Any ideas?

I can’t see the routes.rb, but ain’t that just

new\_review\_path(@product.id)

Thanks, I got it to work with the following:

In the view sending the params information:  
\<%= link\_to ‘Add a Review’, new\_review\_path(:product =\> @product.id)%\>

In the view receiving the params information and passing it to the  
controller.  
\<%= f.hidden\_field :product\_id, :value =\> params[:product]%\>

in routes.rb  
map.resources :products.each do |product|  
product.resource :reviews  
end

and in the view  
\<%= link\_to ‘Add a Review’, new\_product\_reviews\_path(@product,:product\_d  
=\>  
@product.id)%\>
