rails 3.2.11 My app has User model, its one of the fields is entrepreneur:boolean. So users have two types; one is normal users, the other is professional users. For normal users, only emails and usernames are required and other fields are optional. For professional users, in addition to above, addresses and real names are required. Is there any Ruby way to set the requirement depending on the

Hello, all.

Hello, So, after learning ruby on rails and building a great app on my local machine, I need to find a host, deploy, and of course maintain a (staging and) production environment. This all seems very confusing, and I''d like to learn this in an organized manner, step by step: I''ve come across the names: Unicorn, nginx/apache, capistrano, Thin/mongrel, Engine Yard, EC2, etc.,

I have been working on a project based on Michael Hartl''s book Ruby on Rails Tutorial in order to try to teach myself Ruby on Rails. However, when it tries to render a form designed to allow a user to submit a small message, I get an error saying, "undefined method `model_name'' for NilClass:Class". It says the error is at line 1, which is "<%= form_for

Hi I have problem trying to pass the signin failure test. This is the test code of the sessions_controller.rb def create user = User.authenticate(params[:session][:email], params[:session][:password]) if user.nil? flash.now[:error] = "Invalid email/password combination." @title = "Sign in" render

I''m going through Michael Hartl''s Rails tutorial, and I am happy to report that (as of the end of section 7) I''m able to get things working. (That said, I skipped the section on automated testing, as Hartl warned that automated testing is the most likely part of his book to become outdated.) There is a heavy emphasis on the "bundle exec rspec spec" tests.

I''m very new to Rails and I''m quite confused if I can practice Rails in offline mode? I''m following the Ruby on Rails Tutorail by Michael Hartl and I noticed that after generating a new app through the command "rails new app_name", "bundle install" is then called to download the gems specified in the Gemfile. What if I don''t have an

I have 20+ asterisk servers and need to network them together so a phone on any of the servers can call a phone on any other server without any trouble. I can think of IAX trunks between every server. So every server will have an IAX trunk to every server and then prefix bases routing in the dialplan for each server (I can give a number to each server and use that as a prefix for that server).

Hi, I''m using prototype within ruby on rails. One limitation I''d like to overcome is the restriction of beeing able to update just one html elements content using from_remote_tag or link_to_remote. AFAICS this is just a restriction of the form_remote_tag/link_to_remote implementation and it''s underlying Ajax.Updater class. Right? In theorie there should be no problem,

Just a quick thanks to everyone involved with samba3 dev, I upgraded last night from 3.0.7 to 3.0.9 and it went really smoothly - just had to reset the permissions on /var/spool/samba so that people could print again! (It seems to reset perms each upgrade, but at least I know this now!). We are running the following without any hassle: Sage Approch Access all ms office suite openoffice Outlook

Hello, I have been learning Rails for several weeks now. I am working through Michael Hartl''s tutorial and other various things. My question is basically regarding what type of environment to do my development in. First, some background: I have used different linux distros on and off throughout the years, so it was easy and familiar for me to set up my desktop computer with Mint and

Hi everybody ! I want to authenticate a Exchange 5.5 Server against Samba 2.2.8. But the Exchange Server says after using a Samba account: Cant start due to a logon failure: "The User has not been granted the request logon type at this computer" I tracked down the problem and i think that the "SeServiceLogonRight" Privilege is not set by the Samba PDC thus not allowing an
