routing issue, rails generates wrong url

First of all, Happy Thanksgiving.

So my issue is with my routes, I'm not clear on why id param actually contains the entire object. Rails gives me this error:

user_url failed to generate from {:action=>"show", :controller=>"users", :id=>#<User id: 19, username: "Dr. Dorothy Buckridge", email: "kyra@hansenstehr.ca", crypted_password: nil, password_salt: nil, persistence_token: nil, created_at: "2009-11-10 19:38:31", updated_at: "2009-11-10 19:38:31", perishable_token: "", color: nil>}, expected: {:action=>"show", :controller=>"users"}, diff: {:id=>#<User id: 19, username: "Dr. Dorothy Buckridge", email: "kyra@hansenstehr.ca", crypted_password: nil, password_salt: nil, persistence_token: nil, created_at: "2009-11-10 19:38:31", updated_at: "2009-11-10 19:38:31", perishable_token: "", color: nil>}

The error occurs on this line:

<%= link_to recipe.user.username, recipe.user, :class => "user" %>

Any Idea? It seems like it should only be generating the id of the object for that attribute.

My controller in question is:

def index
  @recipes = Recipe.search params[:search], :field开发者_运维百科_weights => { :name => 20, :description => 10 }
end

Can't really see what the issue is.

Did you override to_params in the User model or any class that it inherits?

You can force the id with this:

 <%= link_to recipe.user.username, user_url(recipe.user.id), :class => "user" %>

This is a wild guess, but I had a similar issue when I typed map.resource :user instead of map.resources :users in the routes.rb

Otherwise validate against EmFi's naswer.
