When using Rails 0.13.0 (with ruby 1.8.2 (2004-12-25) ), after reference from Recipe to Category is added, submission of http://127.0.0.1:3000/recipe/edit/1 form doesn't work. It submits to http://127.0.0.1:3000/recipe/update, which shows an following error: ActiveRecord::RecordNotFound in Recipe#update Couldn't find Recipe without an ID script/server:49 Show framework trace Request Parameters: {"recipe"=>{"title"=>"Happy Chips", "id"=>"1", "category_id"=>"2", "description"=>"Only for the brave!", "instructions"=>" Grab a few chips from your colleague. Ask first.\r\n "}} A solution is to change the Edit Recipe edit.rhtml. The line that was: <input id="recipe_id" name="recipe[id]" size="30" type="hidden" value="<%= @recipe.id %>" /> should be: <input id="id" name="id" type="hidden" value="<%= @recipe.id %>" />

Showing messages 1 through 4 of 4.

  I encountered the same problem. I ended up with a different solution:
  
  
<form action="../update/" method="POST">

  
  becomes
  
  
<form action="../update/<%= @recipe.id %>" method="POST">

  
  Would anyone like to offer an 'official' response as to which of these 2 methods is the prefered Rails way?

  SixSide, only your version worked for me with rails 0.13.1 with ruby 1.8.2 (the versions on the website).
  
  Curt, thank you for a fantastic article. But could you please update edit.rhtml as SixSide shows both in the article and in the sample ZIP file, as I believe nearly every reader is wasting time tracking down this bug.
  
  Thanks.

  Sure... I'll confirm the change and ask my editor to update the article.

  Seconded - frankly I'm amazed this fundamental error has persisted for almost 9 months without official correction.
