阅读更多关于 How can I stop Heroku Dyno that is running a Rails task through Heroku Scheduler?

问题 Heroku Scheduler uses a One-off Dyno to run the scheduled task. That dyno doesn't appear in Heroku Dashboard, but it's there. How can I restart it, or temporarily stop it? 回答1: If you have the command line tools installed, heroku ps will list all the running processes, and you can use ps:kill or ps:restart to manage any of them. heroku help ps will give you more details. 回答2: You do not need to restart or stop. There are no dynos on Heroku dashboard, but you can find your scheduler in Heroku

How do I use a custom log for my rake tasks in Ruby on Rails?

阅读更多关于 How do I use a custom log for my rake tasks in Ruby on Rails?

I have a rake task that calls functions like this: namespace :blah do task :hello_world => :environment do logger.info("Hello World") helloworld2 end end def helloworld2 logger.info("Hello Again, World") end I want the log output to a custom log, and I really don't want to have to pass a log reference every time I make a function call.

I can't

Should I use “rake spec” or “rspec” (can't get “rake spec” to work)?

阅读更多关于 Should I use “rake spec” or “rspec” (can't get “rake spec” to work)?

问题 I am on Rails 3.2 and I am using rspec (2.11.1). When I run my test suite with "rake spec" I get failures. When I run it with "rspec" everything passes. I've seen other mentions of this problem but nothing definitive that explains what is going on and what best practices are. If I do "rake spec" or "rake tmp:clear && rake spec" my tests fail. If I do "rspec" or "rspec spec" or "rake db:test:prepare && rspec" my tests pass. I thought the only difference was that rake did "db:test:prepare" but

问题 How to specify gem dependencies in a way that user with only ruby, rake and rubygems installed could issue a single rake command to install all the dependencies required?

If a FLAC file is newer than the corresponding MP3 file (or the corresponding MP3 file doesn't exist), then I want to run a bunch of commands to convert the FLAC file to an MP3 file, and copy the tags across. The kicker: I need to search the flac directory recursively, and create corresponding subdirectories in the mp3 directory. The

问题 I have been trying to run the rake db:migrate command but it ain't working. I uninstalled and installed the gem but no luck. I read somewhere the o.9 wasn't stable and that 0.8.7 was ok.
