Execute a Rake task from within migration?

I have a Rake task that loads configuration data into the DB from a file, is there a correct ruby/rails way to call it on a migration up?

My objective is to sync my team DB configs, without have to broadcast then to run the task lalala

  def self.up
    change_table :fis_situacao_fiscal do |t|
      t.remove :mostrar_endereco
      t.rename :serie, :modelo 
    end
    
    Faturamento::Cfop.destroy_all()
    #perform rake here !
  end

UPDATE How I do now, and works:

system('rake sistema:load_data file=faturamento/cfop')

And this is the suggestion from @Ryan Bigg, and it's exception:

Rake::Task['rake sistema:load_data file=faturamento/cfop'].invoke()

.

==  AlterSituacaoFiscalModeloEndereco: migrating ====================
-- change_table(:fis_situacao_fiscal)
   -> 0.0014s

rake aborted!
An error has occurred, this and all later migrations canceled:

Don't know how to build task 'rake sistema:load_data file=faturamento/cfop'

Where it went wrong?

Yes there's a way to do that:

Rake::Task['your_task'].invoke

Update

Do not put rake inside the brackets, just the name of the task. You should set an ENV variable when running this:

In the console

FILE=somefile.text rake db:sistema:load_data

Calling it separately

FILE=somefile.text rake some:other:task:that:calls:it

This will be available in your tasks as ENV['file']

Note that if you call the Rake task with 'system', you need to check the process status afterwards and raise an exception if the Rake task failed. Otherwise the migration will succeed even if the Rake task fails.

You can check the process status like this:

if !($?.success?)
  raise "Rake task failed"
end

Invoking the rake task is a nicer option - it will cause the migration to fail if the Rake task fails.

You can execute a rake task from within a loaded Rails environment with either Rake::Task['namespace:task'].invoke or Rake::Task['namespace:task'].execute.

You can pass data to the task inside of the invoke or execute method. Example:

Rake::Task['namespace:task'].invoke(paramValue)

This param can be handled in the rake task as follows:

namespace :namespace do
  desc "Example description."
  task :task, [:param] => :environment do |t, args|
    puts args[:param]
    ...
  end
end

This can be executed on the console as:

bundle exec rake namespace:task[paramValue]

This decision fits better, IMHO.

In your case it would be smth like this:

backup_env = ENV.slice('file') if ENV.key?('file')
ENV['file'] = 'faturamento/cfop'
Rake::Task['sistema:load_data'].invoke
ENV.delete 'file'
ENV.merge!(backup_env) if backup_env
