我刚刚将全球化（使用globalize gem）添加到模型中。
型号：
class Information::Blog::Post < ApplicationRecord
self.table_name = 'information_blog_posts'
translates :title, :subtitle
end
迁移：
class CreateInformationBlogPosts < ActiveRecord::Migration[5.1]
def change
create_table :information_blog_posts do |t|
t.references :author, index: true
t.datetime :published_at
t.timestamps
end
end
def up
Information::Blog::Post.create_translation_table! title: { type: :string, null: false }, subtitle: { type: :string, null: false }
end
def down
Information::Blog::Post.drop_translation_table!
end
end
现在，在我的种子中，我添加了这一行：
post = Information::Blog::Post.create(id: 1, author_id: 1, title: 'Test', subtitle: 'Test test test test', locale: 'en')
它使我本地的MySQL数据库播种得非常好。在部署到heroku之后，重置＆amp;迁移我的postres生产数据库，我在播种数据库时遇到以下错误：
