Create a menu out from database entries

Rails
1

Hi

I am starting to work with rails and like to build a very basic cms.

I was using scaffolding.
Page title:string permalink:string body:text.

What I like to do is create a menu out of the database entries
permalink.
Those should link to the fitting pages.

So i modified my index.html.erb from the pages view like this:

<% @pages.each do |page| %>
<%= link_to_unless_current page.permalink, page_path(page) %>
<% end %>

I like to use something like the code above in a div layer as a menu
and link the result to the div layer were the <% yield %> is placed.

I was trying to do this with helper module and also with partials, but
I couldnt solve this.
Do I need ajax? or is there a way to do it with rails only?

Maybe someone has a good tip?

Best regards

In ./app/helpers/application_helper.rb:

def tab_for(name, href, html_options = {} )
#puts ‘tab’, @current_tab.to_s, ‘href’, href.to_s
if @current_tab.to_s.starts_with?(href.to_s.downcase)
#content_tag :span, name, html_options
html_options.merge!(:class => ‘active’)
link_to name, href, html_options
else
link_to name, href, html_options
end
end

In the view layout:

  • <%= tab_for 'Directories', directories_path %>
  • <%= tab_for 'Software', softwares_path %>

The tab_for function does a match on the request path to determine if
its active or not…works well for single level menus, but would need
modification to support sub menus.

Hi,

Actually got a good bit of code for this done.

  1. Scan a available controllers, and add table entries for any “new”
    ones automatically
  2. If updates, generate new tabnav menus automatically at startup.

Sounds like a good candidate for a plugin! Let us know if you go there.
