User model has three keys: is_master, is_standard, is_guest because I originally wanted to use activerecord boolean methods like is_master? or is_power?. However, if it would be better to create a UserType relationship and create my own methods like this: def master? return true if self.user_type = 1 end What's the best practice o...
Having the same problems as this post, except I don't think the solution is the same unfortunately. I'm getting this error message: Rails requires RubyGems >= 0.9.4. Please install RubyGems when I run a script/runner job in Cron, but it works perfectly fine when I run it in a terminal on the same server. The rails server also runs f...

Example class class CallTest def go (do something here) end end Trying to call in C++: rb_funcall(?, rb_intern("go"), 0); What goes in the ? space? I know if I use Qnil there, it...
I have embedded Ruby inside my C++ application. I have generated the bindings using SWIG. Basically, I run the ruby file and then Ruby takes over and calls my C++ class. Based on my previous question, I would like to get the current instance of the class that is defined in the ruby file back to the C++ class so that I may execute insta...
I would like to implement the method User.calculate_hashed_password. I'm trying to use the Shoulda testing library which works with Rails's built-in testing tools, so an answer related to Test::Unit would be just as good as one related to Shoulda (I think). I'm trying to figure out what I need to test and how I should test it. My initia...

I'm looking for a portable interface to POSIX alarm(2) (or similar) in Ruby. That's to say, I would like to be able to set a background timer to send a signal to the current process after n seconds. I have found some good discussion from 2006 on the ruby-talk list that provides a solution using dl/import, but that's a bit of a hack (alb...

Is there a way to iterate over a Time range in Ruby, and set the delta? Here is an idea of what I would like to do: for hour in (start_time..end_time, hour) hour #=> Time object set to hour end You can iterate over the Time objects, but it returns every second between the two. What I really need is a way to set the offset or delt...

After a down vote, I humbly realized that my post was an enormous rant. So I've edited it and summed this down to just the question I'd really like to know.

I recently installed the Macports port of Ruby19 and it's changed my environment settings to point to opt/local in the first instance rather than usr/local where I have my standard 1.8.7 install. I've tried updating my ~/.profile by adding the usual export PATH etc. as the last line but to no avail. I have to run the .profile file each ...
