• Problems running rails server

  - by harristrader

  I just installed the rails env using the Rails installer on my Mac OSX 10.7.4. I create a project using the "rails new" command. When I try to run the "rails server" command I get this message: /usr/local/rvm/gems/ruby-1.9.3-p194/gems/rails-2.3.14/lib/rails_generator/options.rb:32:in `default_options': undefined method `write_inheritable_attribute' for Rails::Generator::Base:Class (NoMethodError) from /usr/local/rvm/gems/ruby-1.9.3-p194/gems/rails-2.3.14/lib/rails_generator/base.rb:90:in `<class:Base>' from /usr/local/rvm/gems/ruby-1.9.3-p194/gems/rails-2.3.14/lib/rails_generator/base.rb:85:in `<module:Generator>' from /usr/local/rvm/gems/ruby-1.9.3-p194/gems/rails-2.3.14/lib/rails_generator/base.rb:48:in `<module:Rails>' from /usr/local/rvm/gems/ruby-1.9.3-p194/gems/rails-2.3.14/lib/rails_generator/base.rb:6:in `<top (required)>' from /usr/local/rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:55:in `require' from /usr/local/rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:55:in `require' from /usr/local/rvm/gems/ruby-1.9.3-p194/gems/rails-2.3.14/lib/rails_generator.rb:37:in `<top (required)>' from /usr/local/rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:55:in `require' from /usr/local/rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:55:in `require' from /usr/local/rvm/gems/ruby-1.9.3-p194/gems/rails-2.3.14/bin/rails:15:in `<top (required)>' from /usr/local/rvm/gems/ruby-1.9.3-p194/bin/rails:23:in `load' from /usr/local/rvm/gems/ruby-1.9.3-p194/bin/rails:23:in `<main>' When I run the $ ruby -v and $ gem -v, I get "ruby 1.9.3p194" and "1.8.24" respectively.

• 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).

• Achieve Rails-style migrations in MS Access VBA application

  - by avguchenko

  This is a simple way to do Rails-style migrations in a VBA application. Just add additional migrations like migration(name, sql_string, database) to run_migratons and call run_migrations somewhere in the beginning of your execution. Function migrate(signature As String, sql As String, dbs As DAO.database) Dim rs As DAO.Recordset Set rs = dbs.OpenRecordset("select * from versions where migration = '" & signature & "'") If rs.EOF Then dbs.Execute (sql) rs.AddNew rs("migration") = signature rs.Update End If End Function Function setup_versions(dbs As DAO.database) Dim t As DAO.TableDef On Error Resume Next Set t = dbs.TableDefs("versions") If Err.Number <> 0 Then dbs.Execute ("CREATE TABLE versions (migration text)") End If Err.Clear End Function Function run_migrations(dbs As DAO.database) setup_versions(dbs) migrate("20100315142400_create_table", "CREATE TABLE table_name (field1 type, field 2 type)", dbs) 'add migrations here' End Function

• 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

  - 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.

• calculate number of working days on a rails form

  - by ash34

  I have two fields, 'from_date' and 'to_date' on my rails form. When a user enters the dates I have to display the number of working days i.e, exclude (sat, sun and a list of other official holidays in a database table). 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.

• rails assets give TypeError (can't dup NilClass)

  I have a rails 3 app that works fine when run under rails s. However, when trying to deploy it to apache2 with fcgi, the asset pipeline breaks. For example, when trying to request /assets/logo.png the log will show: Started GET "/assets/logo.png" for 10.50.10.249 at Tue Apr 10 19:20:39 -0400 2012 TypeError (can't dup NilClass): This happens on either the production or development environments. How can I debug this?

• 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?

• How to evaluate the quality of Rails code?

  - by Fortuity

  In a code review, what do you look for to assess a developer's expertise? Given an opportunity to look at a developer's work on a real-world project, what tell-tale signs are a tip-off to carelessness or lack of experience? Conversely, where do you look in the code to find evidence of a developer's skill or knowledge of best practices? For example, if I'm looking at a typical Rails app, I would be happy to see the developer is using RSpec (showing a commitment to using test-driven development and knowledge that RSpec is currently more popular than the default TestUnit). But in examining the specs for a Rails model, I see that the developer is testing associations, which might indicate a lack of real understanding of Rails testing requirements (since such tests are redundant given that they only test what's already implemented and tested in ActiveRecord). More generally, I might look to see if developers are writing their own implementations versus using widely available gems or if they are cleaning up code versus leaving lots of commented-out "leftovers." What helps you determine the skill of a Rails developer? What's your code quality checklist?

• Custom field names in Rails error messages

  - by Madhan ayyasamy

  The defaults in Rails with ActiveRecord is beautiful when you are just getting started and are created everything for the first time. But once you get into it and your database schema becomes a little more solidified, the things that would have been easy to do by relying on the conventions of Rails require a little bit more work.In my case, I had a form where there was a database column named “num_guests”, representing the number of guests. When the field fails to pass validation, the error messages is something likeNum guests is not a numberNot quite the text that we want. It would be better if it saidNumber of guests is not a numberAfter doing a little bit of digging, I found the human_attribute_name method. You can override this method in your model class to provide alternative names for fields. To change our error message, I did the followingclass Reservation ... validates_presence_of :num_guests ... HUMAN_ATTRIBUTES = { :num_guests = "Number of guests" } def self.human_attribute_name(attr) HUMAN_ATTRIBUTES[attr.to_sym] || super endendSince Rails 2.2, this method is used to support internationalization (i18n). Looking at it, it reminds me of Java’s Resource Bundles and Spring MVC’s error messages. Messages are defined based off a key and there’s a chain of look ups that get applied to resolve an error’s message.Although, I don’t see myself doing any i18n work in the near-term, it is cool that we have that option now in Rails.

• Rails migration for change column

  - by b_ayan

  We have script/generate migration add_fieldname_to_tablename fieldname:datatype syntax for adding new columns to a model. On the same line, do we have a script/generate for changing the datatype of a column? Or should I write sql directly into my vanilla migration? I want to change a column from datetime to date. Thanks

• Rails migrations: Undo default setting for a column

  - by wulfovitch

  Hi Stack Overflow Community! I have the problem, that I have an migration in Rails that sets up a default setting for a column, like this example: def self.up add_column :column_name, :bought_at, :datetime, :default => Time.now end Suppose, I like to drop that default settings in a later migration, how do I do that with using rails migrations? My current workaround is the execution of a custom sql command in the rails migration, like this: def self.up execute 'alter table column_name alter bought_at drop default' end But I don't like this approach, because I am now dependent on how the underlying database is interpreting this command. In case of a change of the database this query perhaps might not work anymore and the migration would be broken. So, is there a way to express the undo of a default setting for a column in rails? Thanks in advance!

• Connect Rails model to non-rails database

  - by the_snitch

  I'm creating a new web application (Rails 3 beta), of which pieces of it will access data from a legacy mysql database that a current php application is using. I do not wish to modify the legacy db schema, I just want to be able to read/write to it, as well as the rails application having it's own database using activerecord for the newer stuff. I'm using mysql for the rails app, so I have the adapter installed. How is the best way to do this? For example, I want contacts to come from the old database. Should I create a contacts controller, and manually call sql to get the variables for the views? Or should I create a Contact model, and define attributes that match the fields in the database, and am I able to use it like Contact.mail_address to have it call "SELECT mailaddr FROM contacts WHERE id=Contact.id". Sorry, I've never done much in Rails outside of the standard stuff that is documented well. I'm not sure of what the best approach would be. Ideally, I want the contacts to be presented to my rails application as native as possible, so that I can expose them RESTfully for API access. Any suggestions and code examples would be much appreciated
