Question

有没有人知道这些东西，我对此感到沮丧。

DEPRECATION WARNING: Calling set_table_name is deprecated. Please use `self.table_name = 'the_name'` instead.(called from <top (required)> at /**/config/environment.rb:12)
==  FillAppIdInCampaignPrices: migrating -  ===================================

rake aborted!

An error has occurred, this and all later migrations canceled:

private method `import' called for #<Class:0x007fc9285fdfe0>

我已经改变了这一点：

set_table_name

到此：

self.table_name = 'the_name'

=============================================== ===================================

这是environment.rb：

require File.expand_path('../application', __FILE__)

 require 'octopus' 

require Rails.root + 'lib/utils'

PublisServer::Application.initialize!

这就是迁移：

class AddApprovedToContents < ActiveRecord::Migration

  class Content < ActiveRecord::Base

    self.table_name = 'contents'

  end

  def up

    add_column :contents, :approved, :boolean, default: false

    add_column :articles, :approved, :boolean, default: false

    Content.update_all approved: true

    Article.update_all approved: true

  end


  def down

    remove_column :contents, :approved

    remove_column :articles, :approved

  end

end

我找不到FillAppIdInCampaignPrices：迁移我不知道从哪里来。

我从来没有像你所呈现的那样创造如此错综复杂的移民，但我必须问为什么＆＃34;为什么＆＃34;你在迁移中有Contact个班级吗？

根据this documentation，您可以在迁移中使用这样的模型：

class AddApprovedToContents < ActiveRecord::Migration

  def up
    add_column :contents, :approved, :boolean, default: false
    add_column :articles, :approved, :boolean, default: false
    reversible do |dir|
       dir.up {
           Content.update_all approved: true
           Article.update_all approved: true
       }
    end
  end

  def down
    remove_column :contents, :approved
    remove_column :articles, :approved
  end

end

私有方法`import'需要＃？
