Question: I am absolutely and totally new to rails, so the answer is probably very simple. Here goes:

My page is generating this error

```
NoMethodError in Tasks#new
Showing app/views/tasks/new.erb where line #3 raised:

undefined method `tasks_path' for #

```

Here is the view:

```
<% form_for(@task) do |f| %>
    <%= f.error_messages %>

    <%= f.label :description %>:
    <%= f.text_field :description %><br />

    <%= f.label :priority %>:
    <%= collection_select(:news, :priority_id, Priority.find(:all), :id, :description) %><br />

    <%= f.submit "Add Task" %>

<% end %>

```

The controller:

```
class TasksController < ApplicationController
    def index
        @all_tasks = Task.find(:all, :order => :id)
    end

    def new
        @task = Task.new
    end ...(more)

```

and the model:

I can't see a problem, but like I said, I'm clueless so far.
Thanks!

```
class Task < ActiveRecord::Base
    validates_presence_of :description

    belongs_to :priority
    has_and_belongs_to_many :staff
    has_and_belongs_to_many :catagory

end

```

Answer: 
Do you have

```
map.resources :tasks

```

in your routes?
Have you generated this example using the scaffold generator? Because if not it might be that you forgot to define the ressource url mapping in the routes.rb:

```
--- a/config/routes.rb
+++ b/config/routes.rb
@@ -1,4 +1,6 @@
 ActionController::Routing::Routes.draw do |map|
+  map.resources :tasks
+

```

Don't forget to restart webrick after you've added the route!
