Hello list,
I'm a fairly nooby Rails developer of very little brain, and this error has
had me confused for the last several hours.
It's a very simple (unfinished) Rails app. It has a model called Tasks. It
has a very basic routes.rb
resources :tasks
root :to => 'tasks#index'
A vanilla controller (create action not properly defined yet because that
would have been next on the list when I ran into this problem)
class TasksController < ApplicationController
def index
@tasks = Tasks.all
end
def new
@task = Tasks.new
end
def create
end
end
And a view for the /tasks/new action
<h1>Create new task</h1>
<%= form_for @task do |form| %>
<%= lots of form. blah blah here... %>
<% end %>
And when the view is rendered I get the following error:
undefined method `tasks_index_path' for
#<#<Class:0x000000020c04e8>:0x000000020b74d8>
Extracted source (around line *#2*):
1: <h1>Create new task</h1>
2: <%= form_for @task do |form| %>
And here are the top few lines of the stack trace:
actionpack (3.0.0)
lib/action_dispatch/routing/polymorphic_routes.rb:114:in
`polymorphic_url'
actionpack (3.0.0)
lib/action_dispatch/routing/polymorphic_routes.rb:120:in
`polymorphic_path'
actionpack (3.0.0) lib/action_view/helpers/form_helper.rb:335:in

actionpack (3.0.0) lib/action_view/helpers/form_helper.rb:307:in `form_for'

`_app_views_tasks_new_html_erb__194514136627382544_17145340__4434388515179536201'
I don't really understand where "tasks_index_path" came from or why form_for
has bombed out so spectacularly, especially given how simple the code is
right now. Can anyone point me at what I might be doing wrong?
Oh yes, it's rails 3.0.0 on ruby 1.9.2 running on Ubuntu 10.04.
Thanks,
Mark
