Best way to simulate the default value for a TEXT column using Ruby on Rails?

I am using the TEXT column in my MySQL database. As indicated in the documentation, it is not possible to set a default value for these columns.

I am currently using the following code to model this behavior:

class Data
  before_save lambda {text_column ||= ''}
end

Is there any better way, more edit / active _record to do this?

If you are happy with the HTML5 solution, have you tried using the: placeholder: text_field attribute?

Also do you want to fill in a text field (which captures a small amount of text) in a column of type "text"? Did you mean text_area?

, "" ActiveRecord, ""

def self.setup(params = {})
  new(params).tap do |v|
    v.text_column = "default value"
    # other defaultings
  end
end

, setup.
