Hi,
I seem to have a fundamental misunderstaning or Rake, Ruby, or
Migrations.(or perhaps all three)
I have done dozens of simple Migrations with just a self.up and
self.down... Now I have one that is more complex and I want to call
other methods within the migration.. but it doesn''t work...
Here is my self.up:
def self.up
drop_old_tables
create_tables
populate_questions
populate_forms
end
here is the error message:
undefined method `drop_old_tables'' for
#<ActiveRecord::ConnectionAdapters::MysqlAdapter:0x499deb0>
I have a drop_old_tables method defined lower down.
Thanks in anticipation for any help
Giorgio

I figured it out myself! All the methods must be class methods as there is no instance I suppose. ie self.drop_old_tables etc. Cheers Giorgio giorgio wrote:> Hi, > > I seem to have a fundamental misunderstaning or Rake, Ruby, or > Migrations.(or perhaps all three) > > I have done dozens of simple Migrations with just a self.up and > self.down...

Make sure the other methods are defined on the same class and as class methods with "def self.x" Michael giorgio wrote:> Hi, > > I seem to have a fundamental misunderstaning or Rake, Ruby, or > Migrations.(or perhaps all three) > > I have done dozens of simple Migrations with just a self.up and > self.down...
