Could ActiveRecord add some comments for a column when create a table?For example use some sentence like this:

create_table :blogs do |t|   t.string, :blog_title, :limit=>100,:null=>false, :comment=>'my blog title' end

After do this,I can use the comment instead of the human name of column,it's more suitable.

Column comments are not part of the table as such and not available in all databases. The normal solution for this sort of requirement is to encode it yourself. In your migration, use something like:

class CreateUsers < ActiveRecord::Migration   def self.up     create_table :users do |t|       t.string :name       t.datetime :dob       t.timestamps     end     if config[RAILS_ENV]['adapter'].match(/oracle|oci/)       execute "comment on column users.name is 'The username of the user'"     end   end   :
