I have the following db/migrate ruby file. When I tried rake db:migrate, it gave error.
class CreateEmployers < ActiveRecord::Migration
def self.up
create_table :employers, {:primary_key => 'emp_id'} do |t|
t.column :emp_name, :string, :limit => 100, :null => false #validate
t.column :company_id, :int, :null => false
t.column :location, :string, :limit => 200, :null => false #validate
t.column :registered_date, :datetime
t.column :is_verified, :boolean, :default => false, :null => false
t.column :is_blacklisted, :boolean, :default => false, :null => false
t.column :emp_grade, :string, :default => 'average', :null => false
t.timestamps
end
end
execute "ALTER TABLE `employers`
ADD CONSTRAINT `FK_EMPLOYERS_COMPANIES`
FOREIGN KEY (`company_id` )
REFERENCES `companies` (`company_id` )
ON DELETE NO ACTION
ON UPDATE NO ACTION;"
def self.down
drop_table :employers
end
end
I got the following error when I ran rake db:migrate. It was okay if I removed execute part.
-- execute("ALTER TABLE `employers` \n ADD CONSTRAINT `FK_EMPLOYERS_COMPANIES`\n FOREIGN KEY (`company_id` )\n REFERENCES `companies` (`company_id` )\n ON DELETE NO ACTION\n ON UPDATE NO ACTION;")
rake aborted!
An error has occurred, all later migrations canceled:
Mysql2::Error: Table 'test.employers' doesn't exist: ALTER TABLE `employers`
ADD CONSTRAINT `FK_EMPLOYERS_COMPANIES`
FOREIGN KEY (`company_id` )
REFERENCES `companies` (`company_id` )
ON DELETE NO ACTION
ON UPDATE NO ACTION;
Companies table was already created and company_id was set as primary key (int(11), not null and auto increment).
ruby version is 2.0.0p0 and mysql version is 5.5.31
Did I do something wrong?
