Could ActiveRecord add some comments when create table

[Wu Junchen]

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
