[筆記][Rails] 將開發環境中的 asset log 過濾不顯示方式，參考 https://gist.github.com/toolmantim/4957786

devlopment.rb

# Add the following configuration to your config/environments/development.rb file
#
# This will set the Rails to log to STDOUT (insetad of log/development.log) as well
# as tag all assets request log lines with [assets]
#
# You can then pipe it into grep to filter out the asset lines
#
#   tail -f log/development.rb | grep -v '\[assets\]'
#
# If you log to STDOUT rather than log/development.rb then you can:
#
#   rails s | grep -v '\[assets\]'
# 
# or:
#
#   foreman start | grep -v '\[assets\]'
 
SomeApp::Application.configure do
 
  # Tag assets requests log lines with [assets]
  config.log_tags = [
    -> request { :assets if request.path.starts_with?(config.assets.prefix) },
    -> request { nil }
  ]
 
  # If you want to log to STDOUT rather than log files
  # config.logger = ActiveSupport::TaggedLogging.new(Logger.new(STDOUT))
