Hey everyone,
Sorry for the novice question but I am trying to get to grips with RoR. I have a very basic sign up and login process in place but am having some difficulty getting the routing correct. I am also unsure whether I am actually being logged out successfully when I push my logout button because it isn’t then displaying the login button as it should.
My setup is as so:
Sessions 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 root_url, :notice => "Logged in!"
else
flash.now.alert = "Invalid email or password!"
render "signup"
end
end
def destroy
session[:user_id] = nil
redirect_to root_url, :notice => "Logged Out!"
end
end
User Controller
class UserController < ApplicationController
def new
@user = User.new
end
def create
@user = User.new (params[:user])
if @user.save
redirect_to root_url, :notice => "Signed Up!"
else
render "user/new"
end
end
end
User Model
class User < ActiveRecord::Base
has_secure_password
validates_confirmation_of :password
validates_presence_of :password, :on => :create
validates_presence_of :email
validates_uniqueness_of :email, :on => :create
end
Sessions/new.html.erb
<h1>Log In</h1>
<%= form_tag login_path do %>
<div class="field">
<%= label_tag :email %>
<%= text_field_tag :email, params[:email] %>
</div>
<div class ="field">
<%= label_tag :password %>
<%= password_field_tag :password %>
</div>
<div class="actions"><%= submit_tag "Log in" %></div>
<%end%>
User/new.html.erb
<% if session[:user_id] %>
<!-- user is logged in -->
<%= link_to logout_path %>
<% else %>
<!-- user is not logged in -->
<%= link_to login_path %>
<% end %>
<h1>Sign Up</h1>
<%= form_for @user do |f| %>
<% if @user.errors.any? %>
<div class="error_messages">
<h2>Form is invalid</h2>
<ul>
<% for message in @user.errors.full_messages %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class = "field">
<%= f.label :email %>
<%= f.text_field :email %>
</div>
<div class = "field">
<%= f.label :password %>
<%= f.password_field :password %>
</div>
<div class = "field">
<%= f.label :password_confirmation %>
<%= f.password_field :password_confirmation %>
</div>
<div class="actions"><%= f.submit %></div>
<% end %>
Finally my Routes file
MadeByV2::Application.routes.draw do
controller :user do
get "signup" => "user#new"
end
resources :users
controller :sessions do
get "login" => "sessions#new"
post "login" => "sessions#create"
delete "logout" => "sessions#destroy"
end
root :to => "user#new"
end
Sorry for the extensive use of code in this post but I figure it’s best to give a well rounded view of everything so people can see where I am going wrong.
Any help you can offer really would be much appreciated because I don’t seem to be getting it myself
Thanks,
Tom
