问题 I'm very new to Rails, so please forgive my lack of understanding. I've installed the latest versions of RubyGems, Ruby, Rails, Rake, and MySQL etc via RubyGems, but I have this problem when starting to make a basic Rails app: Icarus:temporary atg$ rails new people ...

问题 I understand that using postgres on osx is a little difficult because it has its own version running, and so in order to psql to it you need to supply the host name like so psql -h localhost mydatabasename -U me However how do you do this for your database.yml file for all the rail loveliness. If you try to connect with development: adapter: postgresql username: me database: mydatabasename you receive the classic Couldn't create database for {"adapter"=>"postgresql", "username"=>"me",

问题 I'm writing a custom rake task for Rails, and there is a point the program where it summarises what it's going to do and then asks the user if what it's about to do is correct. puts "\n Is this what you want to happen? [Y/N]" answer = gets.chomp if answer == "Y" # commits else if answer == "N" return false #(Aborts the rake task) end However, this code causes the rake to be aborted prematurely; rake aborted! No such file or directory - populate " populate " is the name of the rake task. I

问题 I'm writing a rake script and would like to detect (using Ruby rather than bash if possible) if the user who executed the rake script has root privileges. If it is not root then I would like to terminate the script. 回答1: Use uid or euid in the Process class: raise 'Must run as root' unless Process.uid == 0 回答2: I don't know Ruby, but what you want to check for is if the user ID is 0. In C, you would do this by checking getuid(). From the Unix command line, you could also check the output of

The following doesn't execute task1, task2, task3...which means the global $build_list

问题 I'm trying to better understand how rake works. I've looked on the rake website to see how it works but there isn't a clear explanation for how rake searches for Rakefiles and the steps it goes through in resolving dependencies. Can someone explain how rake works? 回答1: By default rake will look for one of these files under the directory you execute it from : rakefile Rakefile rakefile.rb Rakefile.rb You can look at Rake's Application docs to see this list Additionally, any ruby file including

问题 When ever I run make I get this 'uninitialized constant RDoc::RDoc' error rake -T (in Main) rake aborted! uninitialized constant RDoc::RDoc C:/Ruby186/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2383:in `raw_load_rakefile' (See full trace by running task with --trace) --edit Running --trace it seems the only non rails code is from rdoc_rails.
