Adding password reset functionality to Rails app after Hartl tutorial - ruby-on-rails

Question

I'm new to RoR and have been working my way through the Hartl tutorial (which has been great). I've followed up through Chapter 9 successfully (tweaking things a bit since my ultimate goal is not to make a microposts site). At that point, I decided that I would like to add a 'remember me' check box and reset password functionality to my app, so I bounced over to the railscast tutorial (as suggested by Hartl). The check box went very smoothly, but I've hit a brick wall with the password reset section. It's been one error after the next. I have to admit that I couldn't help myself and tweak a little - I tried to use theform_for syntax instead of the form_tag syntax. I've gotten as far as being able to submit an email address, but then I get a No route matches [POST] "/reset_password/new" message. I've spent the last two days reading similar posts on stackoverflow and trying out the suggestions, but I just can't seem to come up with something that works. Please help!
Here's the nitty gritty:
My password reset view is located at /app/views/reset_password/new.html.erb:
<% provide(:title, 'Reset Password') %>
<h1>Reset Password</h1>
<div class="row">
<div class="span6 offset3">
<%= form_for #user, url: new_reset_password_path do |f| %>
<%= f.label :email %>
<%= f.text_field :email %>
<%= f.submit "Reset Password", class: "btn btn-large btn-methyl" %>
<% end %>
</div>
</div>
My controller is located at /app/controllers/reset_password_controller.rb:
class ResetPasswordController < ApplicationController
def new
#user = User.new
end
def show
end
def create
#user = User.find_by_email(params[:email].downcase)
user.send_password_reset if user
redirect_to root_path, notice: "Email sent with password reset instructions."
end
def edit
#user = User.find_by_password_reset_token!(params[:id])
end
def update
#user = User.find_by_password_reset_token!(params[:id])
if #user.reset_password_sent_at < 2.hours.ago
redirect_to_new password_reset_path, alert: "Reset password request has expired."
elsif #user.update_attributes(params[:user])
redirect_to root_path, notice: "Password has been reset!"
else
render :edit
end
end
end
My routes are located at /config/routes.rb:
Methylme::Application.routes.draw do
resources :users
resources :sessions, only: [:new, :create, :destroy]
resources :reset_password
root to: 'static_pages#home'
match '/signup', to: 'users#new'
match '/signin', to: 'sessions#new'
match '/signout', to: 'sessions#destroy', via: :delete
match '/help', to: 'static_pages#help'
match '/about', to: 'static_pages#about'
match '/contact', to: 'static_pages#contact'
.
.
.
end
Finally, $ rake routes reports the following:
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
PUT /users/:id(.:format) users#update
DELETE /users/:id(.:format) users#destroy
sessions POST /sessions(.:format) sessions#create
new_session GET /sessions/new(.:format) sessions#new
session DELETE /sessions/:id(.:format) sessions#destroy
reset_password_index GET /reset_password(.:format) reset_password#index
POST /reset_password(.:format) reset_password#create
new_reset_password GET /reset_password/new(.:format) reset_password#new
edit_reset_password GET /reset_password/:id/edit(.:format) reset_password#edit
reset_password GET /reset_password/:id(.:format) reset_password#show
PUT /reset_password/:id(.:format) reset_password#update
DELETE /reset_password/:id(.:format) reset_password#destroy
root / static_pages#home
signup /signup(.:format) users#new
signin /signin(.:format) sessions#new
signout DELETE /signout(.:format) sessions#destroy
help /help(.:format) static_pages#help
about /about(.:format) static_pages#about
contact /contact(.:format) static_pages#contact
Thanks in advance for your help!

Answer 1

I don't think you want to link to new_reset_password_path (new) in your password reset view, but to reset_password_path (create), which does send the reset password email.
If your routes don't do what you expect (for instance, the create route does not have an associated xxx_path name) you should simply declare them individually, with
post '/reset_password', to: 'reset_password#create', as: 'send_reset_password' # for example
...
