Rails.logger doesn't log the data into development.log

Question

I simple question:

# development.rb
config.log_level = :debug


class ApplicationController < ActionController::Base
  before_action :my_log

  private

  def my_log 
    Rails.logger.debug <<-LOG
      [CUSTOM DEBUG] 
        some info 123
        #{request.method.inspect}
        ...

    LOG
  end

And still after that development.log is empty.

UPDATE:

It does log the requests, but to the terminal, not to development.log

Just to be sure: you're in the development environment, right? — Jon Egeland, Feb 24 '15 at 04:44
What happens when you print out `Rails.logger` in the pry? (Add the output to your question) — Jon Egeland, Feb 24 '15 at 04:52
@Jon, it shows the data. However, it actually logs (sometimes?) the data to the console, but not to a file. how come? — , Feb 24 '15 at 04:53
Honestly, I have no idea. But this answer might help: http://stackoverflow.com/questions/17749804/using-logger-in-rails-4 Apparently, you should just use `logger.debug` without the `Rails.`. — Jon Egeland, Feb 24 '15 at 04:55

Did you make sure the user running the Rails server has write permissions to the log file?

I've seen this happen if the server is started as root the first time

sudo rails s

which created the development.log file owned by root. Then if a non-privileged user starts the server

rails s

the log file cannot be written to because it's owned by root.
