When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.
To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.
Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.
If the namespace is not used then the commands will perform on top of the default database.
bundle exec rake db:create
bundle exec rake db:migrate
By using the namespace we are going to use all the configuration for our alternate DB.
bundle exec rake store:db:create
bundle exec rake store:db:migrate
Place in a controller action to have the server print to screen the contents of the http request headers.
logger.warn "*** BEGIN RAW REQUEST HEADERS ***"
self.request.env.each do |header|
logger.warn "HEADER KEY: #{header[0]}"
logger.warn "HEADER VAL: #{header[1]}"
end
logger.warn "*** END RAW REQUEST HEADERS ***"
