Dynamic aspects of Rails 4 app not working in production - mysql

Question

I just deployed my first rails 4 app to a VPS and now I cannot write to the production database. Everything deployed fine (migrations etc) and I can log on the mysql database with sequel pro and see it is all there however when I try create a user using the app's new user form instead of notifying 'Thank you for registering' (as it does in development) it asks me to login to proceed. No record is created in the database.
I can see in the log that it is binding show rather than the users id to the :id parameter and therefore redirecting to login rather than creating a session. Why would this be?
This is the app log

Edit 1: Here is my session controller:
class SessionsController < ApplicationController
def new
end
def create
user = User.find_by_email(params[:email])
if user && user.authenticate(params[:password])
session[:user_id] = user.id
redirect_to users_path, notice: "Logged In!"
else
flash.now[:error] = "Email or password is invalid. Please try again."
render "new"
end
end
def destroy
session[:user_id] = nil
redirect_to root_url, notice: "Logged Out!"
end
end
And here is my users controller:
class UsersController < ApplicationController
before_action :authorize, except: [:new]
def new
#user = User.new
end
def edit
#user = User.find(params[:id])
end
def show
#user = User.find(params[:id])
#microposts = #user.microposts.paginate(page: params[:page])
end
def update
respond_to do |format|
#user = User.find(params[:id])
if #user.update(user_params)
format.html { redirect_to #user, notice: 'User was successfully updated.' }
format.json { render :show, status: :ok, location: #user }
else
format.html { render :edit }
format.json { render json: #user.errors, status: :unprocessable_entity }
end
end
end
def destroy
#user = User.find(params[:id])
if #user.present?
#user.destroy
end
redirect_to users_path, notice: "User successfully deleted."
end
def create
#user = User.new(params[:user].permit(:name, :surname, :title, :telefon, :email, :password, :password_confirmation, :salt, :encrypted_password))
if #user.save
session[:user_id] = #user.id
redirect_to root_url, notice: "Vielen Dank für Ihre Anmeldung"
else
render "new"
end
end
def index
#users = User.all
end
private
def user_params
params.require(:user).permit(:name, :surname, :title, :telefon, :email, :password, :password_confirmation, :salt, :encrypted_password)
end
end
