Help With Debugging Ruby on Rails Sample App

I hope this is the right community to post this question in.
I've been working through M.Hartl's Ruby on Rails tutorial for a while now, and I've been able to work out when I've made typos that caused my integration tests to fail and the like, but I've run into one that I can't figure out. My `get edit_password_reset_path()` with correct arguments is redirecting to the home url, not `password_resets/edit` like it should.

The failing test:

FAIL["test_password_resets", PasswordResetsTest, 2015-11-02 15:50:02 +0000]
test_password_resets#PasswordResetsTest (1446479402.08s)
expecting <"password_resets/edit"> but rendering with <[]>
test/integration/password_resets_test.rb:37:in `block in '

Here is my password_resets_test.rb:

require 'test_helper'

class PasswordResetsTest < ActionDispatch::IntegrationTest def setup ActionMailer::Base.deliveries.clear @user = users(:michael) end test "password resets" do get new_password_reset_path assert_template 'password_resets/new' # Invalid email post password_resets_path, password_reset: { email: "" } assert_not flash.empty? assert_template 'password_resets/new' # Valid email post password_resets_path, password_reset: { email: @user.email } assert_not_equal @user.reset_digest, @user.reload.reset_digest assert_equal 1, ActionMailer::Base.deliveries.size assert_not flash.empty? assert_redirected_to root_url # Password reset form user = assigns(:user) # Wrong email get edit_password_reset_path(user.reset_token, email: "") assert_redirected_to root_url # Inactive user user.toggle!(:activated) get edit_password_reset_path(user.reset_token, email: user.email) assert_redirected_to root_url user.toggle!(:activated) # Right email, wrong token get edit_password_reset_path('wrong token', email: user.email) assert_redirected_to root_url # Right email, right token get edit_password_reset_path(user.reset_token, email: user.email) assert_template 'password_resets/edit' # This is the assertion that fails assert_select "input[name=email][type=hidden][value=?]", user.email # Invalid password & confirmation patch password_reset_path(user.reset_token), email: user.email, user: { password: "foobazzz", password_confirmation: "barquuxz" } assert_select 'div#error_explanation' # Empty password patch password_reset_path(user.reset_token), email: user.email, user: { password: "", password_confirmation: "" } assert_not flash.empty? # Valid password & confirmation patch password_reset_path(user.reset_token), email: user.email, user: { password: "foobazzz", password_confirmation: "foobazzz" } assert is_logged_in? assert_not flash.empty? assert_redirected_to user end end Here is my password_resets_controller.rb class PasswordResetsController < ApplicationController before_action :get_user, only: [:edit, :update] before_action :valid_user, only: [:edit, :update] before_action :check_expiration, only: [:edit, :update] def new end def create @user = User.find_by(email: params[:password_reset][:email].downcase) if @user @user.create_reset_digest @user.send_password_reset_email flash[:info] = "Email sent with password reset instructions" redirect_to root_url else flash.now[:danger] = "Email address not found" render 'new' end end def edit end def update if params[:user][:password].empty? @user.errors.add(:password, "can't be empty") render 'edit' elsif @user.update_attributes(user_params) log_in @user flash[:success] = "Password has been reset" redirect_to @user else render 'edit' end end private def user_params params.require(:user).permit(:password, :password_confirmation) end def get_user @user = User.find_by(email: params[:email]) end def valid_user unless (@user && @user.activated? && @user.authenticated?(:reset, params[:id])) redirect_to root_url end end def check_expiration if @user.password_reset_expired? flash[:danger] = "Password reset has expired." redirect_to new_password_reset_url end end end The `authenticated?` method in `user.rb` : # Returns true if the given token matches the digest. def authenticated?(attribute, token) digest = send("#{attribute}_digest") return false if digest.nil? BCrypt::Password.new(digest).is_password?(token) end I'm not super sure what else is needed to figure out my problem. I've searched StackOverflow, worked through the code a second time, and I've even compared the source code at M.Hartl's github repo. [Link to the appropriate branch on my repo.](https://bitbucket.org/WJDeVries/sample_app/branch/account-activation-password-reset) I'm trying to follow exactly [this part of the tutorial.](https://www.railstutorial.org/book/account_activation_password_reset#sec-password_reset) Any help would be appreciated.
