Question

Okay I have been working on this for about 2 hours and am sure there is a very simple solution but unfortunately as a rails novice I can’t seem to find it.

I have set up a basic sign up and login system following Ryan Bates Authetication lesson #270.

I keep however receiving the same error when trying to login.

undefined method `find_by_email' for nil:NilClass

I have my sessions controller set up as follows:

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 root_url, :notice => "Logged in!"
        else
            flash.now.alert = "Invalid email or password"
            render "new"
        end
    end

    def destroy
        session[:user_id] = nil
        redirect_to root_url, :notice => "Logged Out!"
    end

end

But am really unsure how to define find_by_email.

Any advice people can offer me on this really would be much appreciated

Answer 1

user.find_by_email(params[:email])

should be

User.find_by_email(params[:email])
