Problem with UUID generated in partial not being unique

Folks,

I'm using the "uuidtools" package to generate (hopefully) unique values for IDs within a partial (for products being added to an order form, where nothing is saved to the DB until the end).

Unfortunately when I add a new product line (using RJS page.insert.html rendering a partial) the new lines added all have the same UUID.

Here's the code from the (top of the) partial -

<tr class="order_product" id ="<%= if order_product.new_record?          UUID.random_create.to_s       else          order_product.id.to_s       end     %>">

If we have a new product added then we generate a UUID. If it is in edit mode, and we have an existing database record we using the ID of the record as the ID.

When I generate the page initially it puts one product line in place. It has a UUID value. When I click my link to add a new line, it has a different UUID : but adding any further rows still use this second value.

Is there some sort of caching going on ? Or is there some other reason ?

TIA

Phil

How exactly are you doing this? if it's all happening client-side then this is to be expected: the partial is only rendered once (how could it be rendered more than once if there is no roundtrip to the server.
