NoMethodError new to Rails - ruby-on-rails

Question

Ive been following some rails guides and im trying to now implement something on my own for a project im doing and have hit a snag at the first hurdle
I get this error when trying to load the page
ActionController::UrlGenerationError in StepOne#login
Showing /Users/rogan/Sites/authImp/app/views/step_one/login.html.erb where line #3 raised:
No route matches {:action=>"show", :controller=>"step_one"} missing required keys: [:id]
Extracted source (around line #3):
<%= form_for url: step_one_path do %>
form stuff...
then my step_one_controller.rb
class StepOneController < ApplicationController
def new
end
def create
user = User.authenticate(params[:email], params[:password])
if user
pincode = generatePin
puts "one use pin.#{pincode}"
redirect_to "step_two"
else
flash.now.alert = "Invalid email or password"
render "new"
end
end
end
this was adapter from a login system i saw in a guide that used SessionsController.rb and form_for url: sessions_path
but my simple changes seem to have broke it, i've looked at my routes as well and they all seem to be in order
edit: heres is my routes
edit edit: changed everything to step_one and to removed the 's' as suggested, I now get
NoMethodError in StepOne#login
undefined method `model_name' for Hash:Class
<%= form_for url: step_one_path do %>
so from one problem to another!
AuthImp::Application.routes.draw do
resources :users
resources :sessions
resource :step_one
get "users/:id" => "users#show"
get "sign_up" => "users#new"
get "log_in" => "step_one#login"
get "step_two" => "sessions#new"
get "log_out" => "sessions#destroy", :as => "log_out"
then my rake routes is as follows
root to: "welcome#index"
users GET /users(.:format) users#index
POST /users(.:format) users#create
new_user GET /users/new(.:format) users#new
edit_user GET /users/:id/edit(.:format) users#edit
user GET /users/:id(.:format) users#show
PATCH /users/:id(.:format) users#update
PUT /users/:id(.:format) users#update
DELETE /users/:id(.:format) users#destroy
sessions GET /sessions(.:format) sessions#index
POST /sessions(.:format) sessions#create
new_session GET /sessions/new(.:format) sessions#new
edit_session GET /sessions/:id/edit(.:format) sessions#edit
session GET /sessions/:id(.:format) sessions#show
PATCH /sessions/:id(.:format) sessions#update
PUT /sessions/:id(.:format) sessions#update
DELETE /sessions/:id(.:format) sessions#destroy
step_one POST /step_one(.:format) step_ones#create
new_step_one GET /step_one/new(.:format) step_ones#new
edit_step_one GET /step_one/edit(.:format) step_ones#edit

PUT /step_one(.:format) step_ones#update
DELETE /step_one(.:format) step_ones#destroy
GET /users/:id(.:format) users#show
sign_up GET /sign_up(.:format) users#new
log_in GET /log_in(.:format) step_one#login
step_two GET /step_two(.:format) sessions#new
log_out GET /log_out(.:format) sessions#destroy
root GET / welcome#index

Answer 1

your problem is in the naming I think, resources :step_one assumes that you define the StepOnesController (plural), not StepOneController
So, you should either rename your controller or use resource :step_one route (without the s at the end)

Answer 2

It looks like Rails is expecting you to pass in an id to your step_one_path, so the form_for should look like this:
<%= form_for url: step_one_path(#user.id) do %>
Where #user.id would be the id of the user that the form is associated with. Hope that helps. If not, please include your routes.rb file.

Answer 3

<%= form_tag step_one_path do |f| %>
was the form tag necessary, i was going about it wrong
thanks for all the help
