How do you skip failed migrations? (rake db:migrate)

Question

I can\'t seem to find an option or anything that allows me to skip migrations.

I know what you\'re thinking: \"you should never have to do that...\"

I need to sk

Answer 1

sometimes, it is necessary to re-fill schema_migrations table with definitely correct migrations... ONLY FOR THIS PURPOSE i have created this method

def self.insert_missing_migrations(stop_migration=nil)
  files = Dir.glob("db/migrate/*")
  timestamps = files.collect{|f| f.split("/").last.split("_").first}
  only_n_first_migrations = timestamps.split(stop_migration).first

  only_n_first_migrations.each do |version|
    sql = "insert into `schema_migrations` (`version`) values (#{version})"
    ActiveRecord::Base.connection.execute(sql) rescue nil
  end
end

you can copy-paste it into any model you want and use it from console

YourModel.insert_missing_migrations("xxxxxxxxxxxxxx")

(or somehow else)

where "xxxxxxxxxxxxxx" - is timestamp of migration before which you want to stop insertion (you can leave it empty)

!!! use it only if you absolutely understand what result will you get !!!
