Hi everybody,

I have to change a lot of data in production server and I don't know what's
the best way to do it.

To handle the permissions in the older version of my system I had two
models: Group and Permision.

class Group < ActiveRecord::Base
  has_many :actions
end

class Permission < ActiveRecord::Base
  belongs_to :group

  PERMISSION_NAMES = "..."
end

I stored the application permissions inside the model. Now I did a lot of
changes in this code and it looks something like this:

class Group < ActiveRecord::Base
  has_many :actions
end

class Action < ActiveRecord::Base
  belongs_to :group
  belongs_to :permission
end

class Permission < ActiveRecord::Base
  has_many :actions
end

The Permission model holds a list of permissions and their Id. It is like a
domain table. This way a group can have many permissions and a permission
can have many groups. Now comes the problem. I need to deploy these changes
in the production servers. I already have the script to update the changes,
but I don't know what is the conventional place to put it. Not in the
migrations, I know. I put them in the seeds file, but I think is even worse.
Another important thing is that I would love to do some automated tests on
my script. How can I do that.

Many thanks in advance.

Best regards,
Marco Antonio
