After trying to login unsuccessfully my app gives me "No route matches [POST] "/user_session/new" " error

So one last hickup for the night then i'm calling it quits.. when i go to log in to my page weather it is successful or not it throws me the error in the title of the post:

" No route matches [POST] "/user_session/new" "

here is my routes.rb file 

Rails.application.routes.draw do

    resources :users
    resources :user_session, only: [:new, :create]

    root 'user_session#new'
end

here is the user_session new.htnl.erb file

<h1>Log Into S.I.C.</h1>

<%= form_tag @user_session_path do %>
  <div class="login_boxes">
    Badge Number:<%= text_field_tag :badge_number, params[:badge_number] %>
    </br>
    </br>
    Password: <%= password_field_tag :password %>
  </div>
    </br>
    </br>
  <div class="action">
    <%= submit_tag "Log In" %>
  </div>
<% end %>

here is the user_session_controller

class UserSessionController < ApplicationController

  def new

  end

  def create
    user = User.find_by(badge_number: params[:badge_number])
    if user && user.authenticate(params[:password])
      session[:user_id] = @user.id
      flash[:success] = "Welcome to Security Information Center"
      redirect_to users_path
    else
      flash[:error] = "Could not log you into S.I.C. Please check your credentials and try again."
      render action: 'new'
    end
  end

end

OK, so you have to modify your sessions create method, these three lines. They have to all contain either local OR instance variables, not both:

    @user = User.find_by(badge_number: params[:badge_number])
    if @user && @user.authenticate(params[:password])
      session[:user_id] = @user.id

or

    user = User.find_by(badge_number: params[:badge_number])
    if user && user.authenticate(params[:password])
      session[:user_id] = user.id

I created a new user in the console and successfully logged him in after these changes.

This seems odd:

<%= form_tag @user_session_path do %>

It looks like a crossover of a user instance variable and a route helper.

so it actually errors out harder when i remove the @ sign... i looked at the link above but still cant figure this out..

this is that it gives me as routes

Helper HTTP Verb Path Controller#Action Path / Url
users_path GET /users(.:format) users#index POST /users(.:format) users#create new_user_path GET /users/new(.:format) users#new edit_user_path GET /users/:id/edit(.:format) users#edit user_path GET /users/:id(.:format) users#show PATCH /users/:id(.:format) users#update PUT /users/:id(.:format) users#update DELETE /users/:id(.:format) users#destroy user_session_index_path POST /user_session(.:format) user_session#create new_user_session_path GET /user_session/new(.:format) user_session#new root_path GET / user_session#new

Last resort, upload it to github and let me look around :). I'll make a pull request if I find a solution.

GOT THE LITTLE BUGGER... thanks i had in my user_session_controller.rb the following:

def create user = User.find_by(badge_number: params[:badge_number]) if user && user.authenticate(params[:password]) session[:user_id] = @user.id flash[:success] = "Welcome to Security Information Center" redirect_to users_path else flash[:error] = "Could not log you into S.I.C. Please check your credentials and try again." render action: 'new' end end

i removed the @ symbol on line 4 and it passed the login in and took me to the page it needed to!

the only thing i haven't learned as of yet is how to log out of the session and redirect back to the log in screen it dosnt seem to go over that

Just create a destroy action (and route) which changes the session[:user_id] to nil.
