Routes.rb error

casper_the_ghost · February 14, 2008, 4:14am

I’m new to ruby and trying to make a welcome page. I changed routes.rb
to:
map.connect ‘’, :controller => “welcome”

and deleted index.html, but still I get the error:

NameError in WelcomeController#index

uninitialized constant WelcomeController

I havne’t had problems besides that. I’ve followed every step but
can’t figure out how to fix it?

My routes.rb looks like this:

map.connect ’ ', :controller => “main”, :action => “welcome”

Notice that following connect there are two apostrophes, not a quote.
Also, the controller is “main” and the action is “welcome”.

Within the main controller, the following resides:

def welcome
@categories = Category.find(:all)
end

Look into the views folder within welcome.rhtml, and you’d find this:

<% @categories.each do |category| %>

<%= link_to "#{category.name}", :controller => "category", :action => "show", :id => category.id %>

<% end %>

The controller sets up the array that the view peers into and uses to
produce the selection of links.

Hope this helps.

Love AJAX wrote:

Please make sure welcome_controller.rb exists in your controllers
directory and then your views contain a welcome directory with an
rhtml file with the name of your action. In this case it would be
index.rhtml

That worked great…thanks

Please make sure welcome_controller.rb exists in your controllers
directory and then your views contain a welcome directory with an
rhtml file with the name of your action. In this case it would be
index.rhtml
