Pattern: Missing block for Rails.logger.debug
Issue: -
Checks that blocks are used for interpolated strings passed to Rails.logger.debug.
By default, Rails production environments use the :info log level. At the :info log level, Rails.logger.debug statements do not result in log output. However, Ruby must eagerly evaluate interpolated string arguments passed as method arguments. Passing a block to Rails.logger.debug prevents costly evaluation of interpolated strings when no output would be produced anyway.
#bad
Rails.logger.debug "The time is #{Time.zone.now}."
#good
Rails.logger.debug { "The time is #{Time.zone.now}." }
