圈子 ---list

class CreateLists < ActiveRecord::Migration def change create_table :lists, :options => 'DEFAULT CHARSET=utf8' do |t| t.integer :micro_letter_id, :integer, :comment => "微信" # 微信

t.timestamps end

#add_index :lists, [:publish_status, :assigned_user, :team_id, :company_id], name: "user_company_status_index" end end

执行 rake db:migrate，把字段的注释也生成到 mysql 中，这样加了 :comment => "微信"这个参数不管用，请问该怎么做
