So turn "123 Fake Street, San Francisco, CA" into "CA" or "California." (My program will only use the "state" information for now to help determine results, but I'd like to have full

问题 I'm trying to create a custom model to interface with a database that isn't supported navtively by Rails or through the OpenLink ODBC driver. For some reason, I'm getting the following error: no such file to load -- odbc I'm at a lost as to why this is occurring as the ruby-odbc gem is in the GEM_PATH and I have a small script that tests this to ensure that the connection works and it worked perfectly. Does Rails ignore the gem_path? Is there something else I need to configure? I checked the

I have run it in my Ubuntu console and everything works fine, but I can't find a console in the IDE that I can use to run the command and update that environment. I assume there's an easy solution, but google has not helped much in finding it. Any help would be much appreciated. 回答1: For Rubymine 18.1 and above,
