• Ruby but not Rails on my Resume

  - by Ken Bloom

  I have listed Ruby as a skill on my resume becuase I've been programming in Ruby for 5 years while I work on my Ph.D. thesis. I've mostly been using it to implement natural language processing algorithms. I'm starting to look for a job, and I posted my resume to a few sites (as an extra bonus when applying to certain on-target jobs). Now I get recruiters calling me to offer me Ruby on Rails jobs. The problem is that I've never learned Rails. It was never relevant to what I'm doing for my Ph.D. How do you recommend handling this situation to avoid wasting my time and theirs? (And learning Rails probably isn't an option until I finish my thesis.) Can my resume be adjusted to make this clearer? Should it be adjusted? Should I just politely tell them on the phone that I don't know Rails? By the way, the relevant part of my resume simply says: Skills: Programming Languages: C, C++, Java, Scala, Ruby, LaTeX Databases: MySQL, XML, XPath and lists a few other skill areas that couldn't possibly be confused with a Rails developer.

• Rails/Node.js interaction

  - by lpvn

  I and my co-worker are developing a web application with rails and node.js and we can't reach a consensus regarding a particular architectural decision. Our setup is basically a rails server working with node.js and redis, when a client makes a http request to our rails API in some cases our rails application posts the response to a redis database and then node.js transmits the response via websocket. Our disagreement occurs in the following point: my co-worker thinks that using node.js to send data to clients is somewhat business logic and should be inside the model, so in the first code he wrote he used commands of broadcast in callbacks and other places of the model, he's convinced that the models are the best place for the interaction between rails and node. I on the other hand think that using node.js belongs to the runtime realm, my take is that the broadcast commands and other node.js interactions should be in the controller and should only be used in a model if passed through a well defined interface, just like the situation when a model needs to access the current user of a session. At this point we're tired of arguing over this same thing and our discussion consists in us repeating to ourselves our same opinions over and over. Could anyone, preferably with experience in the same setup, give us an unambiguous response saying which solution is more adequate and why it is?

• Good resources for learning Rails?

  - by Bobby Tables

  I just finished working through Peter Cooper's "Beginning Ruby". So now I've got a reasonable grounding in the Ruby language and would like to move onto learning Rails. This question's answers give some good pointers, but I'd like to hear some specific reviews of books and online materials. I generally learn best by working through books with good practical/technical examples AND some passive reading content that breaks up the study between practical and reading sessions (this is what made "Beginning Ruby" great for me), but I'm worried that RoR is evolving fast and that any printed book I order might be obsolete by the time I get it and work through it. Is this a fair worry? Or can anyone recommend a good Rails 3 book that should be up to date at least for the next year or so? Also, I had a brief look at some of the online resources from the other questions, and Rails for Zombies seems to get a lot of praise. Has anyone here actually used it as their introductory guide to Rails? Basically I'd like to hear first-hand accounts of people who went through this "Ruby-to-Rails" learning phase recently and which materials were useful to you.

• Backbone.js, Rails and code duplication

  - by Matteo Pagliazzi

  I'm building a web app and I need a JS framework like Backbone.js to work with my backend rovided by Rails that mostly return JSON objects after DB queries. Searching on the web I've discovered Backbone which seems to be complete, quite populare and actively developed but I've noticed that a lot of things done by Backbone are simply a duplicte of the works done by Rails: for example validation and models. My idea of "perfect" (for my actual needs) JS mvc (it can't be called mvc but i don't have any other names) is something really simple that has a function for each action in my Rails controller that are triggered by a specific event (user/hash changes, click on a button...) and send requests to the server that respond with a JSON object then I'll load a template or execute some JS code. Do you have any concern/suggestion about my idea? Do you know some "micro" js framework like what i have described? If you have worked with backone.js + rails what can you suggest me?

• Is there a canonical resource on multi-tenancy web applications using ruby + rails

  - by AlexC

  Is there a canonical resource on multi-tenancy web applications using ruby + rails. There are a number of ways to develop rails apps using cloud capabilities with real elastic properties but there seems to be a lack of clarity with how to achieve multitenancy, specifically at the model / data level. Is there a canonical resource on options to developing multitenancy rails applications with the required characteristics of data seperation, security, concurrency and contention required by an enterprise level cloud application.

• Back again to use Rails 2.3.5 from Rails 3

  - by dreame4

  Hi, Recently, I had seen information about Rails 3.0 beta and I had wanted to trial it. So I used gem update and installed this version. But now, I need to go back to Rails 2.3.5. How could I do it? I was thinking about this two solutions: Uninstalling Rails 3. I read that somebody removed Rails 3 by using gem uninstall but he came across some problems then. Did anyone try to remove it in this way? Using different versions Rails at the same time. Is it possible at all? It will resolve all my problems but I could find nothing about this issue in google. Hope somebody could help me :) Greetings, dreame4

• Rails 2.3.4 Vs Rails 3 + Book - Beginner in RoR

  - by zengr

  Hi, I have started with Ruby and Rails development and I am a Java developer from the last 2 years (student). I am in for two things: Learn Ruby Make my website on ROR I have Agile Web Development with Rails, 2nd Edition. So, here are my questions: How is the Agile Web Development with Rails book to start with, where I don't know anything about Ruby and proficient with Java. What is the difference between 2nd and 3rd edition? People say the changes are irrelevant for a starter, how far is that statement correct? Should I start with Rails 2.3.4 or Rails 3 (around the corner)?

• Precompile assets for a rails engine

  - by Peter Ehrlich

  In a standard app, I have this line in my production.rb, which creates endpoints for non-default precompiled assets: config.assets.precompile += %w( mobile.css ) My rails engine is a standard Sinatra app. It has its own assets. When on development, these assets are served fine, presumably the web requests are handled by rails and sprockets. On production I'm getting 404s on the assets, and think I have to manually tell sprockets to provide the files. How can this be done without tightly linking? It isin't evident how to set up env-specific initializers for engines. Is this done? Not only, for example, is config/development.rb within the engine not loaded, but there's no way to get the application class itself without knowing its name, in order to modify configuration. And even if there was, it seems that having any engine able to reconfigure the main app would be very bad idea. So maybe its better to let assets handling be done by sinatra itself? Or another instance of sprockets for the engine? How do other engines handle this?

• rails + sheevaplug = rails home development server and more

  - by microspino

  Hello I'd like to build a "Rails Brick" using a Sheevaplug from Marvell (O.S. is Ubuntu out of the box but You can install other distributions on It). It will be a home server and a silent, low cost (99$) low energy development machine. I'd like to add rails RVM, lot of gems, git-based heroku like deployment, passenger + nginx. This way I could have a portable server with a complete development environment and maybe I could find a hosting company where I can co-locate a grid of this devices or I can sell It as a simple little server for 10 or less users offices, with some centralized rails services (I think to a CMS, a BLOG, a WIKI, calendar or whatever this little jewel could afford). The usb port could make It a print server too or a UMTS link to the web via HUAWEI like usb UMTS keys. Can you give me some hint about: Is this project a crazy-close-to-failure idea? Why? which gem would You include? which rails open source app would you suggest? I have already an Excito Bubba Server at home, I saw the TonidoPlug so It came up in my mind to build something similiar but Rails based (Bubba is PHP based, TonidoPlug I don't know but It does not seems a Rails thing).

• Jrails and jquery-rails together?

  - by ecoologic

  I hope you forgive me if I'm a little confused about this. Jrails rewrites all the helper methods for rjs otherwise in prototype. Jquery-rails overrides rails.js (so I taught the rjs helpers as well, but I see it's not) and the rest of the libraries in jquery instead of prototype. Does it means that with just Jquery-rails I can't use rjs at all? Then do these gems work well together and let me completely forget prototype? Is there any disadvantage in using them together? I read some complaining about the fact that jrails uses jq 1.5 and now there is 1.8, but jquery-rails gives me the last version (is there retro compatibility?), but how will this affect my development (using both the gems together)? I mean have you got some examples of jquery-ui plugins I can't use or I could have problems with? Any help is appreciated. Don't get me wrong, I'm not against prototype, just I keep on having conflicts over conflicts using both of them, and I have to chose I pick Jquery.

• Cannot Access Rails Server From Outside LAN

• Rails Full Engine using a Full Engine

  - by SirLenz0rlot

  I've got this full rails engine Foo with functionality X. I want to make another engine, engine Bar, that is pretty much the same, but override funcitonality x with y. (it basically does the same, but a few controller actions and views are differently implemented). (I might split this later in several mountable engines, but for now, this will be the setup: project Baz, using engine Bar, which uses engine Foo) I would like to know if there are any pitfalls. It doesn't seem like a pattern that is often used? Anybody else using this 'some sort of engine inheritance'?

Is this something that should be done in the client side javascript Or is this something that should be done by making an ajax request to rails. Can you tell me how I can accomplish this. thanks much.

Does anyone know an elegant way to accomplish this, preferably in a way that doesn't break the ability to run "rails destroy" with the generator?
