• Should I use scaffolding or not in Ruby on Rails?

  - by dpacmittal

  I'm learning Ruby on Rails for a new project of mine. I am referring the book 'Agile Web Development with Rails' which shows how to build a shopping cart and they use scaffolding. I'm pretty familiar with MVC architecture and have used several frameworks in PHP to build applications. I've never used scaffolding and I'm not sure if that's the best way to start building an application. Experienced users, please suggest if I should be using scaffolding or should I code manually.

• Is possible to create an intranet site in Ruby on Rails? [closed]

  - by Akromyk

  I'm just coming out of a .Net course and I'm wondering whether it is possible to create an intranet site using Ruby on Rails, and if so, would it even be a good idea. I plan on creating a web site for a vendor that hopes to open up a physical location and it would be beneficial for us to go with a technology that could tie their web front into their intranet for helping them manage orders and logins, but at the same time still have a low cost.

• How to process a .proto file using protobuf-net

  - by JustSmith

  I have stated using the protobuf-net lib to communication between some of the programs I'm maintaining. I have also been able to decode messages from C# to Ruby. My ruby ProtoBuf lib is using a .proto file to generate the ruby code. In the interest of having to make changes in as few places as possible I would like to have protobuf-net use the same .proto file. Looking though the protobuf-net folders there is a Dll named ProtoBufGenerator and the protobuf exe but I cant find any instructions on if I can make protobuf-net work this way. Is this possible?

• 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)?

• has_many :through when join table doesn't contain FK to both tables

  - by seth.vargo

  I have a structure that isn't really a has_many :through example, but I'd like it to behave like one: # user.rb belongs_to :blog has_many :posts # post.rb belongs_to :user # blog.rb has_many :users has_many :posts, :through => :users # this obviously doesn't work becase # both FKs aren't in the blogs table I want to get ALL posts for a blog in an array. I'm aware that I can do this with Ruby using each or getting fancy with collect, but I'd like to let SQL do the work. Can someone explain how I can set up my models in a way that lets me call @blog.posts using SQL, not Ruby? Edit: I know in SQL I can write something like: SELECT * FROM posts WHERE posts.user_id IN ( SELECT users.id FROM users WHERE users.blog_id = 7 ) which obviously shows two queries are needed. I don't think this is possible with a join, but I'm not totally sure. It's obvious that a subquery is needed, but how do I get rails to build that subquery with ARel instead of having to return and use Ruby to loop and collect and such?

• How do (or can I) hack a gem temporarily while looking for a bug?

  - by Tom Andersen

  I have a gem installed in my home directory on a laptop (eg not THE server). I have installed ruby 1.9.1 and also some other gems, notably right_aws - which allows access to s3, etc with ruby. All works, except there is a bug when I do a query on SimpleDB, and the returned list of items includes an item with any two byte utf-8 character in its itemName(). So I look through the sources of the right_aws gem installed on my machine, and I can see some places where I would like to test a fix. If I edit the file, save changes, (needing a password), then restart the server (script/server), it ignores my changes. I am quite new at ruby - do you have to 'compile' or other similar move to get the source code changes made take effect? I can see the edited file is changed by viewing it in terminal, etc.

• Difference in heat output between IDE and SATA hard drives?

  Just a general question: is one supposed to produce more heat than the other? I took my HP DC7100 SFF desktop, swapped the 80 GB SATA for a 250 GB IDE HDD and the IDE drive temperature sensor seems to be less than the previous SATA.

• Ruby - Immutable Objects

  - by Chris Bunch

  I've got a highly multithreaded app written in Ruby that shares a few instance variables. Writes to these variables are rare (1%) while reads are very common (99%). What is the best way (either in your opinion or in the idiomatic Ruby fashion) to ensure that these threads always see the most up-to-date values involved? Here's some ideas so far that I had (although I'd like your input before I overhaul this): Have a lock that most be used before reading or writing any of these variables (from Java Concurrency in Practice). The downside of this is that it puts a lot of synchronize blocks in my code and I don't see an easy way to avoid it. Use Ruby's freeze method (see here), although it looks equally cumbersome and doesn't give me any of the synchronization benefits that the first option gives. These options both seem pretty similar but hopefully anyone out there will have a better idea (or can argue well for one of these ideas). I'd also be fine with making the objects immutable so they aren't corrupted or altered in the middle of an operation, but I don't know Ruby well enough to make the call on my own and this question seems to argue that objects are highly mutable.

• Ruby send mail with smtp

  - by songdogtech

  I'm trying to send simple email via Ruby (no rails) on OS X, with XCode (which installs Ruby.) But I'm running into a problem with my smtp server which requires the email client to check mail before sending as a form of authentication. So with the script below I get an error: 500 Unrecognized command (Net::SMTPAuthenticationError). How can I get Ruby to authenticate with the smtp server in a "POP" fashion before I can send mail? Not download mail; I only want to send, but I have to check mail before I send. POP3 is not available at the smtp server. And I want to not have to install any other Ruby pieces and stay with using net/smtp, if at all possible. require 'net/smtp' message = <<MESSAGE_END From: A Test Sender <[email protected]> To: A Test User <[email protected]> Subject: e-mail test This is a test e-mail message. MESSAGE_END Net::SMTP.start('mail.domain.com', 25, 'localhost', '[email protected]', 'password', :plain)

• Properly using Log4r in Ruby Application

  - by Spencer

  I must really be missing something obvious, but I'm having trouble with general use of Log4r in my Ruby application. I am able to log without issue, but the overhead seems clunky the way I have it setup. I'm basically passing the full path to a filename to log in each class in my application. The ruby script that is called pulls the log file from one of the arguments in ARGV which is then passed around and set in each class that I call in ruby. In each class I use the patternFormatter to insert the class/file name into the log statement. Is there a better way to make this work? It feels like no matter what I think of will require something to be passed to each class in my ruby application. I could set the log file in a yaml configuration file instead, but then I would be passing around the configuration file to each class as well. Any advice? If this doesn't make sense I could try and post some more specific code samples to further explain what I mean. Thanks!

• Ruby: what is the pitfall in this simple code excerpt that tests variable existence

  - by zipizap

  I'm starting with Ruby, and while making some test samples, I've stumbled against an error in the code that I don't understand why it happens. The code pretends to tests if a variable finn is defined?() and if it is defined, then it increments it. If it isn't defined, then it will define it with value 0 (zero). As the code threw an error, I started to decompose it in small pieces and run it, to better trace where the error was comming from. The code was run in IRB irb 0.9.5(05/04/13), using ruby 1.9.1p378 First I certify that the variable finn is not yet defined, and all is ok: ?> finn NameError: undefined local variable or method `finn' for main:Object from (irb):134 from /home/paulo/.rvm/rubies/ruby-1.9.1-p378/bin/irb:15:in `<main>' >> Then I certify that the following inline-condition executes as expected, and all is ok: ?> ((defined?(finn)) ? (finn+1):(0)) => 0 And now comes the code that throws the error: ?> finn=((defined?(finn)) ? (finn+1):(0)) NoMethodError: undefined method `+' for nil:NilClass from (irb):143 from /home/paulo/.rvm/rubies/ruby-1.9.1-p378/bin/irb:15:in `<main>' I was expecting that the code would not throw any error, and that after executing the variable finn would be defined with a first value of 0 (zero). But instead, the code thows the error, and finn get defined but with a value of nil. >> finn => nil Where might the error come from?!? Why does the inline-condition work alone, but not when used for the finn assignment? Any help apreciated :)

• Fix an external dependency of a ruby gem

  - by Patrick Daryll Glandien

  I am currently trying to install the gem nfoiled, which provides a ruby interface to ncurses. I do this by using gem install elliottcable-nfoiled as suggest in the README. Downloading it manually from the github repository and then installing it with rake install doesn't work because of a problem with the echoe-gem, thus I am bound to use the normal way. Unfortunately it depends on the gem ncurses-0.9.1 which is only compatible with ruby 1.8, and thus I can't install nfoiled either (since it always tries to compile ncurses-0.9.1 first): novavortex:/usr/src# gem install elliottcable-nfoiled Building native extensions. This could take a while... ... form_wrap.c: In function `rbncurs_m_new_form': form_wrap.c:395: error: `struct RArray' has no member named `len' form_wrap.c: In function `rbncurs_c_set_field_type': form_wrap.c:619: error: `struct RArray' has no member named `len' form_wrap.c: In function `rbncurs_c_set_form_fields': form_wrap.c:778: error: `struct RArray' has no member named `len' form_wrap.c: In function `make_arg': form_wrap.c:1126: error: `struct RArray' has no member named `len' make: *** [form_wrap.o] Error 1 Gem files will remain installed in /usr/local/lib/ruby/gems/1.9.1/gems/ncurses-0.9.1 for inspection.

• Making RDoc Ruby Gem Default on Mac OS X

  - by jkale

  Hey all, I've recently installed RDoc version (2.4.3) through Ruby gems to replace the one shipped with Mac OS X (version 1.0.1). Unfortunately, I can still only use RDoc 1.0.1 when I call run "rdoc" at the command line. rdoc -v returns: RDoc V1.0.1 - 20041108 I tried amending the $PATH variable to point the first entry to the RDoc 2.4.3 folder but no luck. I couldn't find anything about this online either, so I thought I'd ask here. Cheers! Update: Running "gem list -d --version 1.0.1 rdoc" returns: *** LOCAL GEMS *** rdoc (2.4.3) Authors: Eric Hodel, Dave Thomas, Phil Hagelberg, Tony Strauss Rubyforge: http://rubyforge.org/projects/rdoc Homepage: http://rdoc.rubyforge.org Installed at: /usr/local/lib/ruby/gems/1.8 RDoc is an application that produces documentation for one or more Ruby source files Therefore, it's definitely the Mac OSX version of RDoc that's interfering with the Gems version. Update 2: I found out, using: `bash --debugger rdoc` that the old version of RDoc was in /opt/local/bin. I deleted it and added my gems directory to my $PATH `export PATH=/usr/local/lib/ruby/gems/1.8/gems/` I now have a fresh working copy of the latest RDoc!

• Understanding Symbols In Ruby

  - by Kezzer

  Despite reading this article, I'm still confused as to the representation of the data in memory when it comes to using symbols. If a symbol, two of them contained in different objects, exist in the same memory location, then how is it that they contain different values? I'd have expected the same memory location to contain the same value. As a quote from the link: Unlike strings, symbols of the same name are initialized and exist in memory only once during a session of ruby I just don't understand how it manages to differentiate the values contained in the same memory location. EDIT So let's consider the example: patient1 = { :ruby => "red" } patient2 = { :ruby => "programming" } patient1.each_key {|key| puts key.object_id.to_s} 3918094 patient2.each_key {|key| puts key.object_id.to_s} 3918094 patient1 and patient2 are both hashes, that's fine. :ruby however is a symbol. If we were to output the following: patient1.each_key {|key| puts key.to_s} Then what will be output? "red", or "programming"? FURTHER EDIT I'm still really quite confused. I'm thinking a symbol is a pointer to a value. Let's forget hashes for a second. The questions I have are; can you assign a value to a symbol? Is a symbol just a pointer to a variable with a value in it? If symbols are global, does that mean a symbol always points to one thing?

• XML-RPC over SSL with Ruby: end of file reached (EOFError)

  - by Michael Conigliaro

  Hello, I have some very simple Ruby code that is attempting to do XML-RPC over SSL: require 'xmlrpc/client' require 'pp' server = XMLRPC::Client.new2("https://%s:%d/" % [ 'api.ultradns.net', 8755 ]) pp server.call2('UDNS_OpenConnection', 'sponsor', 'username', 'password') The problem is that it always results in the following EOFError exception: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/protocol.rb:135:in `sysread': end of file reached (EOFError) So it appears that after doing the POST, I don't get anything back. Interestingly, this is the behavior I would expect if I tried to make an HTTP connection on the HTTPS port (or visa versa), and I actually do get the same exact exception if I change the protocol. Everything I've looked at indicates that using "https://" in the URL is enough to enable SSL, but I'm starting wonder if I've missed something. Note that Even though the credentials I'm using in the RPC are made up, I'm expecting to at least get back an XML error page (similar to if you access https://api.ultradns.net:8755/ with a web browser). I've tried running this code on OSX and Linux with the exact same result, so I have to conclude that I'm just doing something wrong here. Does anyone have any examples of doing XML-RPC over SSL with Ruby?

• Python, Ruby, and C#: Use cases?

  - by thaorius

  Hi everyone. For as long as I can remember, I've always had a "favorite" language, which I use for most projects, until, for some particular reason, there is no way/point on using it for project XYZ. At that point, I find myself rusty (and sometimes outdated) on other languages+libraries+toolchains. So I decided, I would just use some languages/libs/tools for some things, and some for other, effectively keeping them fresh (there would obviously be exceptions, I'm not looking for an arbitrary rule set, but some guidelines). I wanted an opinion on what would be your standard use cases (new projects) for Python, Ruby, and C# (Mono). At the moment, I have time like this:Languages: C#: Mid-Large Sized Projects (mainly server-side daemons) High Performance (I hardly ever need C's performance, but Python just doesn't cut it) Relatively Low Footprint (vs the JVM, for example) Ruby: Web Applications Python: General Use Scripts (automation, system config, etc) Small-Mid Sized Projects Prototyping Web Applications About Ruby, I have no idea what to use it for that I can't use Python for (specially considering Python is more easily found installed by default). And I like both languages (though I'm really new to Ruby), which makes things even worse. As for C#, I have not used a Windows powered computer in a few years, I don't make things for Windows computers, and I don't mind waiting for Mono to implement some new features. That being said, I haven't found many people on the internet using it for server-sided *nix programming (not web related). I would appreciate some insight on this too. Thanks for your time.

• rspec and ruby 1.9.1: problem with dummy controller and routes

  - by giorgian

  I want to test a module that basically executes some verify statements, to ensure that actions are invoked with the correct method. # /lib/rest_verification.rb module RestVerification def self.included(base) # :nodoc: base.extend(ClassMethods) end module ClassMethods def verify_rest_actions verify :method => :post, :only => [:create], :redirect_to => { :action => :new } ... end end end I tried this: describe RestVerification do class FooController < ActionController::Base include RestVerification verify_rest_actions def new ; end def index ; end def create ; end def edit ; end def update ; end def destroy ; end end # controller_name 'foo' # this only works with ruby 1.8.7 : 1.9.1 says "uninitialized constant FooController" tests FooController # this works with both before(:each) do ActionController::Routing::Routes.draw do |map| map.resources :foo end end after(:each) do ActionController::Routing::Routes.reload! end it ':create should redirect to :new if invoked with wrong verb' do [:get, :put, :delete].each do |verb| send verb, :create response.should redirect_to(new_foo_url) end end ... end When testing: $ ruby -v ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux] $ rake RestVerification :create should redirect to :new if invoked with wrong verb Finished in 0.175586 seconds $ rvm use 1.9.1 Using ruby 1.9.1 p378 $ rake RestVerification :create should redirect to :new if invoked with wrong verb (FAILED - 1) 1) 'RestVerification :create should redirect to :new if invoked with wrong verb' FAILED expected redirect to "http://test.host/foo/new", got redirect to "http://test.host/spec/rails/example/controller_example_group/subclass_1/foo/new" Is this a known issue? Is there a workaround?

• Ruby on Rails Mongrel web server stuck when MySQL service is running

  - by Marcos Buarque

  Hi, I am a Ruby on Rails newbie and already have a problem. I have started the Mongrel web server and it works fine when MySQL service isn't running. But when MySQL is on, Mongrel stucks. It ceases from serving the pages. So far, I have tested the localhost:3000 URL. When MySQL is off, it serves the page. When I click "about application's environment", I get the messasge (of course) "Can't connect to MySQL server on 'localhost' (10061)". After starting the MySQL service and refreshing, I get no more answer and Mongrel does not serve the webpage. It gets stuck with no answer to the browser. Then I have to stop the webserver and restart it. I have installed mysql2 gem with the command gem install mysql2. I was able to create the _test and _development databases with the command line rake db:create. I have tested with MySQL root user and blank password and also tried with a superuser user I have created. No success. Here is the server log: ======================== Started GET "/rails/info/properties" for 127.0.0.1 at Fri Dec 24 17:41:25 -0200 2010 Mysql2::Error (Can't connect to MySQL server on 'localhost' (10061)): Rendered C:/Ruby187/lib/ruby/gems/1.8/gems/actionpack-3.0.3/lib/action_dispatch/middleware/templates/rescues/_trace.erb (1.0ms) Rendered C:/Ruby187/lib/ruby/gems/1.8/gems/actionpack-3.0.3/lib/action_dispatch/middleware/templates/rescues/_request_and_response.erb (5.0ms) Rendered C:/Ruby187/lib/ruby/gems/1.8/gems/actionpack-3.0.3/lib/action_dispatch/middleware/templates/rescues/diagnostics.erb within rescues/layout (35.0ms) ================= I am running on a Windows 7 environment with firewall down.

• LoadError in Ruby

  - by wilhelmtell

  I'm having issues requiring 'digest/sha1'. ~$ ./configure --prefix=$HOME/usr --program-suffix=19 --enable-shared ~$ make ~$ make install ~$ irb19 irb(main):001:0> require 'digest/sha1' LoadError: dlopen(/Users/matan/usr/lib/ruby19/1.9.1/i386-darwin9.8.0/digest/sha1.bundle, 9): Symbol not found: _rb_Digest_SHA1_Finish Referenced from: /Users/matan/usr/lib/ruby19/1.9.1/i386-darwin9.8.0/digest/sha1.bundle Expected in: flat namespace - /Users/matan/usr/lib/ruby19/1.9.1/i386-darwin9.8.0/digest/sha1.bundle from (irb):1:in `require' from (irb):1 from /Users/matan/usr/bin/irb19:12:in `<main>' irb(main):002:0> I know some standard modules require fine, while others don't. If i'd say require 'yaml' or even require 'digest' then that works fine. I am using OS X 10.5.8, with Ruby 1.9.1-p378. The system-wide install of Ruby 1.8.6 works fine. Just last week I uninstalled Ruby and re-installed it. When I first installed Ruby I installed it in a similar manner, from source prefixed at my local $HOME/usr directory. I tried removing each and every file make install installs, then re-installing, but that didn't help. Do you have an idea what the issue is and how to resolve it?

• Ruby on Rails: custom instance creation failing at redirect

  - by Jack

  I am at an absolute loss as to what I am doing wrong with the following code. I am trying to implement a messaging system within my application, but want it to be handle different types of messages. In this case, I want to create a "request" message of ':message_type = 1'. Instead of using forms as I usually have, I want to make this instance the moment the link is clicked. Here is how I have it set up in the show erb file for "user": <%=link_to "Send friend request", :action=>"request", :controller => "messages", :id => @user.id %> and in the controller: def request @message = Message.new(:sender_id => current_user.id,:user_id => params[:id],:message_type => 1) if @message.save flash[:notice] = 'Message was successfully created.' redirect_to message_path(@message) else redirect_to message_path(@message) end end This results in the following error message: undefined method `rewrite' for nil:NilClass with the trace looking like c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/whiny_nil.rb:52:in `method_missing' c:/ruby/lib/ruby/gems/1.8/gems/actionpack-2.3.5/lib/action_controller/base.rb:634:in `url_for' (eval):16:in `message_path' app/controllers/messages_controller.rb:11:in `request' I have used map.resources :messages in the routes.rb file, and done the appropriate :has_many and :belongs_to associations in the models of user and message.

• Ruby, Python, or PHP?

  - by Gabe

  And so we return to the age old question - but with a few twists. This morning, I searched and read up on which web development language to learn first. I'm thinking Ruby, Python, or perhaps PHP. But I have a few questions before deciding. Background: I'm a year into C++ (through school), but want to get into web development. I have all summer to commit to one language, learn it, do some projects, get up some websites, and so on. Now my questions (and these are assuming that I should choose between Ruby, Python, and PHP - if I should choose a different language, let me know.): I hope to use whichever language I learn for websites/web apps. Some of the threads on stackoverflow suggested Python was the best overall language, but others were unanimous that Ruby was best specifically for web development. For a first language suited towards web development, which language do you recommend, and why? This might tie into the first question, but which language looks most promising for future work, future personal projects, and basically the future in general? I'm just a freshman in college. Ideally, the language I choose would be on the rise, community-wise and opportunity-wise. (One reason I'm leaning towards Ruby is that it seems a lot of the newer tech startups/successes are using it.)
