And this week we have a special guest, Noah Gibbs. Good to be here. But do you want to introduce yourself anyway? Chef, Capistrano, stuff like that. But I just give you all the code and initial setup instead of making you work through all the systems. And so, it comes out as a guided tour through Ruby metaprogramming.

Because a lot of Rails is structured around the way Ruby lets you do it. I talk a little about other ways to do things. There are a few things that I structure a bit like Sinatra, especially say, my early routing. I think dispel the idea is a little bit strong. A given tool is usually really useful in some cases and not others.

And I find that just by showing people all the details of how this metaprogramming stuff works, yeah most people tend to either really dive into the tool or really pull back from it. So, dispel the idea is a bit strong. I wrote a book on it. Sometimes explicitly, sometimes by implication. But if you mean what tools do I think Rails is bad for?

What People are Saying...

So, mostly Rails is not as good for really simple cases, API sort of cases, high-performance cases. It leaves a lot. And Rails does about as much as any framework can do. Even in say Rails 4 they were still adding new things that gave you much better security by default. And nothing stops you from putting an API server beside it. Nothing stops you from building you API in Sinatra quickly, building your app in Rails quickly, and given the Rails routing system you can do that in a massive hurry.

One of the things I explore in the book and talk about is how Rack is used all the way up and down the Rails stack. I hear from a lot of people a lot of, particularly first time authors, that they wrote something because they wanted to understand it better.

Is that part of your motivation here? What I really did here was I wrote the book I wish I had had. And so, taking that apart layer by layer was exactly what I wish I could have done right when I started.

I did all that on my own before I wrote the book. But the book was my way of handing that knowledge to somebody else the same way I had to do it for myself. How did you go about learning everything you needed to know to understand how Rails works? So, this will sound worse than I mean it, but in some ways reading Ruby code feels like preschool posters to me. And mostly Ruby code just works better and reads easier.

And of course, the Rails codebase is very clean. They rewrite little chunks of it all the time. Compared to any C codebase I have ever read, the Rails codebase is like literature.

I began with just making a second library so that you have an app, just making a miniature framework. You can do that in 20 or 30 lines or less. But controllers are probably the next thing.

Rebuilding Rails: Get Your Hands Dirty and build Your Own Ruby Web Framework

You can render the text in the controller instead of having a view if you want to. So, you can cut off the views that way. But if what you want is the smallest little lib framework that you can get, controllers are a good place to start.

And then the next thing is probably views. You can implement a controller framework in 15 or less lines, depending on what you want. You can implement a view framework in a similarly small number of lines. ERB is built right into Ruby these days and Erubis is really easy to use. Most of what surprised me as I was building this was how small the smallest version of each of these things can be, how small your simple view framework can be.

It only supports GET. But you can write the Sinatra style routing language in under 15 lines easily. I will say that Sinatra itself is kind of dirty in internal structure.

I had the good fortune to work with the folks at OnLive until recently. The company sank. But I built a custom Ruby framework on top of Sinatra. We did some really interesting things there and we did at least manage to open source that. But one of the problems we persistently had is that Sinatra is structured a little bit weird.

Sometimes a framework is just very self-contained. But Sinatra is structured a little weirdly in several ways. I have never looked at the Lotus framework. Yeah, Sinatra is not at all modular. Sinatra is definitely not built to be taken apart.

I think some of the cruft in Sinatra, some of the additional line count, is because Rack was not as good when they started. Rack has grown upward as the frameworks have grown downward, to take over more and more of the functionality.

So, things like cookies and sessions and how they track that stuff, Rack does the vast majority of that at this point. It is a compatibility library over all of the different application servers for serving requests, for returning responses, and for the things that most web interfaces are going to want to do. I take too many things for granted there. And then it will receive output from the program. There are much more complex interfaces than CGI these days. But CGI is sort of the granddaddy of them.

But that is the API that your web server is using and passing to your program to serve that web request. And so, Rack is like that. Rack is the API that your Ruby program uses.

Obviously you could just write a free standing web server. It is entirely possible to write a little Ruby program that talks directly to Apache or that just opens a TCP socket and serves web requests directly.

And so, I just thought it was interesting that you went there instead of say, well the routing or the asset pipeline or the way that you handle certain types of requests. So, I would say that like most large frameworks, Rails is a combination of those two things. If you want to separate it the first thing you do is scrape the top level off, like you can just use Active Support or you can just use Active Record. So yeah, to me those are the same kind of tradeoff.

But I agree, a lot of it is not exactly web related. Rails is both a programming model and happens to also be used for a web server, if that makes sense.

The programming model is interesting. Once you get to the point of having a longstanding service that wants to keep doing things Rails is a terrible pattern for that. And you should separate that out of your Rails codebase and into a second codebase sitting next to it. But yeah, so Rails is both of those.

The web patterns are interesting. But I would say that most of the web patterns rather than the programming model patterns are not quite as weird. Oh look, I can get a list of instance variables.

Oh, I can turn that into a hash table.

Oh, I can pass that hash table through and set it as variables. Then go ahead and do this. But the idea is that the controller defines pieces of data that the view will have access to.

And so, the controller actions mostly go away. As much as you can you make the controller actions go away. So basically, a controller besides for the built-in variables, a controller is going to just be setting one instance variable and passing that down to the view.

And that instance variable refers to a view model object which has everything else that the view might possibly need. This sounds like a presenter object. But I might be misunderstanding. This book is not yet featured on Listopia.

Community Reviews. Showing Rating details. More filters. Sort order. Dec 13, Frank Mcgeough rated it really liked it. Dated at this point but still a valuable and interesting book.

It starts from ground zero and attempt to recreate a successful web framework Rails step by step. While doing so it points out all sorts of interesting features of Ruby and how Rails is able to use them to get "magical" behavior.

Oct 10, Ben Akroyd rated it liked it. This is a great concept. But this book really needs a professional editor. The code referenced has errors, particularly towards the end. Still, the concept is so great that you can almost forgive the sloppy execution.

This book walks you through building a full, working framework and points you to where you can learn even more.
