Using the MuSQL2 gem? Getting the error ‘server has gone away’? Then read on my friend!
After spending WAY too much time trying to find an answer for the correct
fix for the error
ActiveRecord::StatementInvalid Mysql2::Error: MySQL
server has gone away: I eventually came across this answer.
Put the following code into a file
``` ruby config/initializers/mysql_fix.rb module ActiveRecord::ConnectionAdapters class Mysql2Adapter alias_method :execute_without_retry, :execute
def execute(*args) execute_without_retry(*args) rescue ActiveRecord::StatementInvalid => e if e.message =~ /server has gone away/i warn "Server timed out, retrying" reconnect! retry else raise e end end end end ```
This is only a slight tweak from the MySQL gem version, but properly works for the MySQL2 gem.
