Re: navigation list order by

[Rick]

Not sure from your question, you seem to be asking "How do I sort the Categories index?" but you've provided a link_to that deals with a single Category. Typically, you'ld order your Categories in the controller index method and the ordered list would be available in the index.html.erb view as @categories. You could then step through this list in your view with @catagories.each do |category|.

If that's what you've done then "category" (in your link_to) should be the id of a single category.

At any rate, you would really help yourself by getting familiar with the Rails Guides at http:guides.rubyonrails.org.

Hello Everybody

I have a navigation that draws data from a category table, I would like to display the navigation by category ID order, this is the code I have so far

<%= link_to category.title, category_path(category) %> in the view

not sure where to go next to get order by category id

Hi Steve:

Try the following:

<% Category.order("id DESC).each do |category| %>

rather than Category.all ...

See http://guides.rubyonrails.org/active_record_querying.html#ordering

on the actual categories page the categories are listed in category_id order correctly, I have the following code in my controller 

  # GET /categories

  # GET /categories.json

  def index

    @categories = Category.order('id asc')

  end

The only problem is the navigation list that I have put into the application layout page seems to have a mind of its own, here is the code for 

<li class="link"><% Category.all.each do |category| %>

  <%= link_to category.name, category_path(category), :order => ('id desc') %>

<% end %></li>

        </ul>

      </div>

    </nav> 

it just displays the list in a random order.

So why are you using Category.all instead of @categories?

If, by "application layout page" you mean app/views/catagories/index.html.erb, use @categories.each not Category.all.each.
