In this portion of the series, we will create the foundation for a login page and deal a little bit more with the Model portion of MVC.
We need to be able to assign the following information to a user.
- First Name
- Last Name
- Email Address
- Password
- Admin (true/false)
This is where the Model comes in. Before we jump into that, let's create a Users controller similar to the way we create a Home controller in the last post.
 |
| Note that the "new" following Users simply states that a "new" action (method) will be automatically defined in the controller for you. |
Also, we should briefly cover how you connect to a database with Rails. In this tutorial, we will stick with the default configuration/database, SQLite. Navigate to config/database.yml:
If you remember Part 2 of the series, we covered the 3 default modes of Rails. This is the reason there are 3 different database configurations in this file. It is useful as your local development environment database will differ from Production (ex: database username, password, and host would/should be different).
When we are running in development mode, the database we will be using will be db/development.sqlite3 as specified on line 8. The naming convention refers to it's location and filename.
So nothing really to change there, let's go ahead and create the model.
Command(s) Breakdown:
- rails - Invoking a Rails command
- g - Short for generate, used to generate Rails items
- model - specifies that we are generating a model
- Users - the name of the model which, actually refers to both the model (app/models/users.rb) and a table in the database
- first_name:string (etc.) - The first portion is the name of the column in the table and the second part (string) identifies the variable type to be stored in the database.
Now, upon generation, the model is created but the db table/columns do not yet exist. To make this happen, let's run rake db:migrate.
To give you a visual of what was just created...
 |
| Note the table "users" has been created along with the columns we identified during model creation. |
This is great and later if you'd like to add an additional column to your local db, you can. What if you'd like to add a column so that the next person to download your code and run rake db:migrate also has the new column? Navigate to db/migrate/ and you'll see a file that ends in _create_users.rb. This is where you would make that change. Do NOT edit the db/schema.rb file for that purpose (this is overwritten by the migrate files).
Next, create a sessions controller:
Time to add code to the session controller (app/controllers/sessions_controller.rb).
Notice the new and create actions. The gist of this, AFAIK, is that Rails uses new to instantiate a new instance of the Model object and create will actually save data and perform some of the more permanent actions. For our purposes, the "GET" request to the sessions#new and the new.html.erb file will show a login form. Once 'POST'-ing from that login form, the create method will receive the email and password parameters.
Code Breakdown:
Line 6 - Calls a method in the User model (authenticate).
Line 8 - Extract a user ID from the user's session
Line 9 - redirects to a home path once authenticated
Line 11 - A user did not authenticate correctly and we want to send them back to the login page.
The next thing we need to discuss are the changes to your routes.rb file:
Lines 3 - The first portion (ex: logout) identifies a request for that resources, goes to sessions#destroy.
Line 8 - Our root has changed to the login page (app/views/sessions/new.html.erb)
Line 10-12 - We've identified resources (controllers) and instantiated some default routes. 7 to be exact:
You can run `rake routes` to see these.
 |
| 7 routes automatically created for the actions: index, create, new, edit, show, update, destroy |
Note that 7 routes were not manually defined by you, in your routes file but rather, Rails created them for you. This is because you specified `resources :<controller name>` in your routes.rb file. You can create views and controller actions whose names match the names of those 7 defined routes (index, create, etc.). They automagically have routes!
Code breakdown:
Line 5 - form_tag is a Rails method, notice how we encapsulate it in <%= %>. This is how we separate Rails code from regular HTML. You may also see <% %>.
Line 7, 8, 11, 12 - Rails methods that are converted by Rails to define labels and input fields.
Line 14 - submit_tag, again, a Rails method. Note the {:class => "btn btn-primary"}. This is a Twitter-Boostrap definition you can find
here.
Now fire up your instance, you should see the following:
 |
| Note: You can't necessarily use this yet but it looks nice :-) |
This was a lot of information (read: lengthy post) and while the login does not yet work, we will wrap all of this up in Part 5 of the series. While part 5 of this series will walk you through the details of the code, you can always skip ahead and grab it from this
Railscast (if you'd like to finish up).
Thanks!

If you've been following along in this series you've already created a Rails application called "attackresearch, configured your Ruby/gem environment with RVM, and created a Rake task to start the application with Unicorn.
In this portion, we will create our first Rails page and configure the appropriate routes.
Now, first thing first, remove the index.html file located under the public directory:
 |
| Removing this file removes the new Rails application landing page as it is unecessary. |
Fire up the server using the rake task created earlier in this series and browse to the site.
Uh-oh:
Why did this occur? Rails requires some direction from you, the developer. Where does the default or "root" page live and how do I get there?
Like any good map, you need to show a route. That being said, open config/routes.rb and take a look at what I mean:
Notice the comment? Each comment block provides instructions on mapping routes in various ways. You can delete them :-). Leave the first and last line (actual code) but remove the comments.
Now that we know where to map out the route to our destination, let's create a destination. The first thing we want to do is go to our terminal and enter the following (this only has to be done once):
Remember the twitter-bootstrap-rails gem we added in the first part of this series? We just installed it. This allows us to forego some CSS and HTML work and piggyback off those of the Twitter designers (thanks gals/guys).
Next, we will generate our first controller and view. As of right now, we don't necessarily require a model. First, here is a quick break down of MVC:
- Model - Used for handling data resources (databases, usually).
- View - Renders HTML content to users.
- Controller - Code that handles the bulk of the logic and decision making.
Generating a "Home" controller:
 |
| We used --skip-stylesheets as they are unnecessary when using twitter-bootstrap |
Note that a new *View* folder was created app/views/home and a controller file "app/controllers/home_controller.rb".
One thing to be aware of. The name of your controller will have `_controller.rb` appended to it. This is the standard convention.
Time to make an entry in routes.rb. The first thing we need to define is a landing page so that if you request our URL, you have a starting page. We will call it "welcome". There are a few things that have to happen:
- Make an action inside the home controller called "welcome".
- Create a view page under the /app/views/home folder called "welcome.html.erb".
- Configure the route but since this is our first, we will simply use `root :to => "<controller>#<action>"
 |
| Note: Rails does not require code within the action (method), only that it exists. |
 |
| Note: Only one root route can exist. |
Time to edit the welcome.html.erb...
 |
| Note that the h1 tag is has a look and feel defined by the h1 definition in Twitter's CSS. |
 |
| Welcome Page |
..And with that we have a website, sort of. To recap we covered generating a controller and making a view page as well as adding the action with the home_controller called "welcome".
That last thing I'll cover before the next tutorial is the flow of a request. So when you request http://localhost/ this is what is happening.
- The config/routes.rb file is checked to see where this request should go.
- Since the request is for the root page '/', it is rerouted to the Home controller and Welcome action.
- Immediately following any code executing in the Welcome action (none right now), the request finally lands on the view page or the last part in it's journey, welcome.html.erb.
Again, the flow is route -> controller -> view.
If you want to see what I mean, we can stop the flow from reaching the view stage by (welcome.html.erb) by rendering content at the controller. Observe:
 |
| Added the directive render :text => <some text> which stops the flow from reaching the view page and renders content itself. |
 |
| The outcome of this change. |
Thanks for following along, more to come in the next post as we dig a bit deeper with routes and the MVC.

backdoor embedded Event:
Chaos Communication Congress 27th (27C3) 2010 Abstract: Want to persistently backdoor a laptop? Backdooring the BIOS is out of the question since your target can dump and diff it? Planting hardware is out of the question as well? Shhhhhhh.. I have something for you: Embedded controllers are present in every modern laptop, yet their security impact has been unresearched thus far. An embedded controller has access to the complete stream of keyboard scan codes, can control fans and the battery charging process. Backdooring the embedded controller is a powerful way to plant a persistent firmware keylogger that works in a cross-platform fashion. Since ECs usually also provide battery and temperature sensor readings through ACPI, there also exists a way to funnel out the keystroke data through a low-privilege process later. Some laptops even allow EC controller firmware updates over the LAN! I will present a PoC backdoor for a widespread series of laptops and show you how to defend yourself against this attack by dumping the EC firmware yourself.

There’s another video after the break where he walks through the various features but here’s the gist of it. This works on Mac and Windows and allows a sort of ‘live play’ or midi mapping mode.
