• Ruby on Rails function grapher

  - by Hock

  Hi, I'm looking for a function grapher that I can use in a small Rails application I'm working on for my university. Is there anything out there? If it needs the values (points) is not a problem but it would be better if it just parsed the equation. The functions will be 100% in ruby format (for example Math.exp(3*x))... Thanks a lot!

• Is it possible to use best_in_place with typeahead from twitter bootstrap?

  - by Dave H

  Basically, I am using best_in_place in my rails webapp to let users edit their profile info in place. The thing is, I would like users to be presented with a typeahead form for certain entries.. Here's what I'm working with: <p>College/University: <input type="text" class="span3" style="margin: 0 auto;" data-provide="typeahead" data-items="8" data-source='["University of Pennsylvania","Harvard","Yale","Princeton","Cornell","Brown","Columbia","Dartmouth"]'></p> This gives me a working form box with typeahead. However, I want to be able to wrap this in best_in_place with something like <%= best_in_place @student, :education %> so that users only see the typeahead form when they click on the text, and upon clicking away from the box or hitting enter the selection is stored in the database. Is there a reasonably easy way to do this?

• Is it possible for beginner to learn and develop an application in rails in 4 months?

  - by Parth

  I want to develop a web application or a website using rails. My current knowledge includes 1. HTML 2. CSS 3. C 4. Java And I am currently going through 5th chapter of the well grounded rubyist book by David A. Thomas. I came to know that learning ruby is beneficial for good knowledge of rails. So currently I am going through the basics of ruby. And learning rails in parallel. I want to know if in this scenario is it practically feasible to understand rails and develop an application/website in it within the time frame of 4 months. I need to develop an application which have atleast 3 complexity (complex functionality). Any ideas of good application for rails beginners is welcomed. But the application should be large or if it is small than it should have some complexity. Time is a constraint for me. I would have to develop application for college work but rails technology is my choice as I want to learn it.

• Snow Leopard upgrade -> reinstalling sqlite3-ruby gem problem

  - by Carl Tessler

  Hi all, I got ruby 1.8.7 (native compiled), rails 2.3.4, OSX 10.6.2 and also sqlite3-ruby. The error I'm getting when accessing the rails app is NameError: uninitialized constant SQLite3::Driver::Native::Driver::API History: I upgraded to snow leopard by migrating my apps with a FW-cable from my old macbook to the new one. Everything was running perfectly for months, but Yesterday I needed to install watir, which was dependant on rb-appscript, which didn't build due a "wrong architecture" error in libsqlite3.dylib. I figured the build was made on the old machine, so i wanted to rebuild sqlite3-ruby: $ sudo gem uninstall sqlite3-ruby $ sudo gem install sqlite3-ruby Building native extensions. This could take a while... ERROR: Error installing sqlite3-ruby: ERROR: Failed to build gem native extension. /usr/local/bin/ruby extconf.rb checking for fdatasync() in -lrt... no checking for sqlite3.h... yes checking for sqlite3_open() in -lsqlite3... no * extconf.rb failed * Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options. It seems like the sqlite3 libs are not working properly. I've tried to install macports sqlite3 (sudo port install sqlite3) and use that instead, but with same result... so i rebuild sqlite3 from scratch.. download-configure-make-make install. After that, the gem now builds perfectly, but doesn't work in rails, giving the error in the top of this article. I'm not really sure where to go from here because I've tried the following Rebuild sqlite3 from newest source (http://www.sqlite.org/download.html) Reinstalled sqlite3-ruby (sudo gem uninstall sqlite3-ruby && sudo gem install sqlite3-ruby) Used sqlite3 from macports (sudo port install sqlite3 && sudo gem install sqlite3-ruby) Reinstalled rails (sudo gem install rails sqlite3-ruby ) and updated environment.rb to rails 2.3.5. No avail, I still get this error: NameError: uninitialized constant SQLite3::Driver::Native::Driver::AP from /usr/local/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:105:in const_missing' from /usr/local/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.5/lib/sqlite3/driver/native/driver.rb:76:in open' from /usr/local/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.5/lib/sqlite3/database.rb:76:in `initialize' Btw, I have Xcode installed from the Snow Leopard CD. What can i do to solve the problem?

• _mask and Rails

  - by Eric Koslow

  So I am trying to get the cancan gem to work with my rails 3 app and I've hit a problem. I tried to copy the code that Ryan Bates (the creator of the gem) used in his screen cast, but I get an error saying that roles_mask is not a method. I figure that the _mask method was removed from Ruby/Rails at some point, and I'm now wondering what is the replacement. Here's the code in my user.rb model: named_scope :with_role, lambda { |role| {:conditions => "roles_mask & #{2**ROLES.index(role.to_s)} > 0 "} } ROLES = %w[admin student principal admissions] def roles=(roles) self.roles_mask = (roles & ROLES).map { |r| 2**ROLES.index(r) }.sum end def roles ROLES.reject { |r| ((roles_mask || 0) & 2**ROLES.index(r)).zero? } end def role? roles.include? role.to_s end def role_symbols roles.map(&:to_sym) end I'm using Rails 3 and Ruby 1.9.2dev Thank you

• Cannot Access Rails Server From Outside LAN

  - by Mike

  Hello All This is my first post here. I have a rails server I'm running on a dedicated server that I have jail shell access to. I can start up a rails server and access it just fine using the text-based browser elinks running in that jail shell using both internal and public IP's. However, I cannot access the rails server from outside that chrooted environment. Does anyone have any ideas as to what might be going on? Any help would be appreciated. Thanks.

• How can I move from Java and ColdFusion to Ruby on Rails?

  - by Ciaran Archer

  Currently I work with ColdFusion 9+ and some Java in a Windows environment. Prior to ColdFusion, my background was in Java and JSP. I'm considering a move towards Ruby on Rails, as I think it would be a real challenge, keep things fresh, and provide more job opportunities. In order to get into it, I started to build my personal website in Rails 3.0. But what else can I do to make this transition from what I know now to Ruby and Rails? Are there specific or idiomatic aspects of Ruby or Rails I should keep in mind when switching over from a ColdFusion and Java mindset?

• Ruby rail debug output

  - by Darkerstar

  Hi all: I am just starting to write ruby rails. I wrote a controller but is getting wrong number of "arguments (1 for 0)" error, I can't understand why. It has no information on where the error occurred? It has a full list of stack traces but my controller file is not in there! In my controller I have just two methods, that I was going to test out activemq. But after I put the controller out, I got the above error, so I commented out all the code, but I still get the same error. I can't figure out why. I searched google for ruby debug, I have not found anything helpful. Here is my controller source: class ActivemqTestController < ApplicationController def send #client = Stomp::Client.open("stomp://localhost:61613") #station_id=101 #data = {'station_id' => station_id, 'username' => 'yangyanzhe'} #client.publish('/listener/add', data) end def receive #client = Stomp::Client.open("stomp://localhost:61613") # Processing loop #client.subscribe('/listener/add', headers) do |msg| # Process your message here # Your submitted data is in msg.body #puts msg['username'] + " joined " + msg['station_id'] + "\n" #client.acknowledge(msg) #end #client.join # Wait until listening thread dies end end This is the error: ArgumentError in Activemq testController#index wrong number of arguments (1 for 0) RAILS_ROOT: D:/rubyapps/radio Application Trace | Framework Trace | Full Trace f:/Ruby/lib/ruby/gems/1.8/gems/actionpack-2.3.5/lib/action_controller/base.rb:532:in `send' f:/Ruby/lib/ruby/gems/1.8/gems/actionpack-2.3.5/lib/action_controller/base.rb:532:in `process_without_filters' f:/Ruby/lib/ruby/gems/1.8/gems/actionpack-2.3.5/lib/action_controller/filters.rb:606:in `process' f:/Ruby/lib/ruby/gems/1.8/gems/actionpack-2.3.5/lib/action_controller/base.rb:391:in `process' f:/Ruby/lib/ruby/gems/1.8/gems/actionpack-2.3.5/lib/action_controller/base.rb:386:in `call' f:/Ruby/lib/ruby/gems/1.8/gems/actionpack-2.3.5/lib/action_controller/routing/route_set.rb:437:in `call' Thank you for any help in advance.

• Ruby on Rails / Yellow Maps For Ruby Plugin woes...

  - by Zach

  Okay I've read through the plugin comments and the docs as well and I have yet to come up with an answer as to how to do this. Here's my problem I want to use the :info_window_tabs and the :icon option, but I don't know what format to pass my information in. According to the documentation the following code should be correct. Here's my code: @mapper.overlay_init(GMarker.new([map.lat, map.lng], :title => map.name, :info_window_tabs => [ {:tab => "HTML", :content => @marker_html}, {:tab => "Attachments", :content => "stuff"}], :icon => { :image => "../images/icon.png" })) The readme and documentation can be viewed here. And the relevant ruby file that I am trying to interact with, including the author's comments, can be viewed here. I have tried the #rubyonrails channel in IRC as well as emailing the author directly and reporting an issue at GitHub. It really is just a question of syntax. Thanks!

• Call task more than once in Rails 3 generator

  - by balexand

  I'm writing a Rails 3 generator that creates two different models. Here's a very simplified example of what I'm trying to do: def my_generator_task invoke "model", ["foo"] invoke "model", ["bar"] end The problem is that the Thor invoke method only invokes a task once, so the second call to the "model" task never happens and the "bar" model is never created. 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?

• Trying to use a authlogic-connect as a plugin in place of gem - Server doesn't start

  - by Arkid

  I am trying to use Authlogic-connect as a plugin in Rails 3 in place of a gem. I have made an entry in the gemfile as gem "authlogic-connect", :require => "authlogic-connect", :path => "localgems" Now when I run the bundle install, it runs fine. When I try to start the server i get the error Could not find gem 'authlogic-connect (>= 0, runtime)' in source at localgems. Source does not contain any versions of 'authlogic-connect (>= 0, runtime)' Try running `bundle install`. I have placed the unzipped Gem renamed as authlogic-connect in the localgems folder. what is the problem? Here is what I get on using rails plugin install arkidmitra$ rails plugin install git://github.com/viatropos/authlogic-connect.git Usage: rails new APP_PATH [options] Options: [--skip-gemfile] # Don't create a Gemfile -d, [--database=DATABASE] # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db) # Default: sqlite3 -O, [--skip-active-record] # Skip Active Record files [--dev] # Setup the application with Gemfile pointing to your Rails checkout -J, [--skip-prototype] # Skip Prototype files -T, [--skip-test-unit] # Skip Test::Unit files -G, [--skip-git] # Skip Git ignores and keeps -r, [--ruby=PATH] # Path to the Ruby binary of your choice # Default: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -m, [--template=TEMPLATE] # Path to an application template (can be a filesystem path or URL) -b, [--builder=BUILDER] # Path to an application builder (can be a filesystem path or URL) [--edge] # Setup the application with Gemfile pointing to Rails repository Runtime options: -q, [--quiet] # Supress status output -s, [--skip] # Skip files that already exist -f, [--force] # Overwrite files that already exist -p, [--pretend] # Run but do not make any changes Rails options: -h, [--help] # Show this help message and quit -v, [--version] # Show Rails version number and quit Description: The 'rails new' command creates a new Rails application with a default directory structure and configuration at the path you specify.

• Rails 3 memory issue

  - by Erik

  Hello! I'm developing a new site based on Ruby on Rails 3 beta. I knew this might be a bad idea considering it's just beta, but I still thought it might work. Now though I'm having HUGE problems with Rails consuming huge ammounts of memory. For my application today it consumes about 10 mb per request and it doesn't seem to release it either. So I thought this might be because of bloat in my application and thus I created a test app just to compare. For my test app I just generated a model with a scaffold and then created about 20 records on this model. I then went to the index page and hit refresh and I could immediately see memory taking off! Less than my app but still about 1-3 mb per request. I'm working in OSX Leopard, with Ruby 1.8.7, Rails 3.0.0.beta and a SQLLite db for development. Does anyone recognize my problem? I would really appreciate some help here. :/ Thanks!
