Rails Money迁移失败

问题描述 投票：0回答：1

我正在尝试导入所有迁移。但是，在create_table块中使用t.monetize :total, currency: { present: false }似乎崩溃，并出现以下错误消息：

class AddAddressAndOrder < ActiveRecord::Migration[5.1]
  def change
    create_table :line_items do |t|
      t.belongs_to :order
      t.integer :quantity, default: 0
      t.monetize :price, currency: { present: false }
      t.monetize :total, currency: { present: false }
      t.timestamps
    end
  end
end


*** ArgumentError Exception: wrong number of arguments (given 1, expected 2..3)

每次我进入t.monetize（或t.money）列引用时，我都会收到相同的错误...在下面添加（包括--trace）：

** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:migrate

Tasks: TOP => db:migrate

关于Money-Rails，我的Gemfile.lock看起来像这样：

money (~> 6.10.1)
money-rails (1.10.0)
  activesupport (>= 3.0)
  monetize (~> 1.7.0)
  money (~> 6.10.0)
  railties (>= 3.0)

文档（https://github.com/RubyMoney/money-rails#migration-helpers）声明这应该没问题。所以我不知道该怎么做。

问题似乎在MoneyRails::ActiveRecord::Migration::Table.monetize方法中：

module MoneyRails
  module ActiveRecord
    module MigrationExtensions
      module Table
        def monetize(accessor, options={})
          [:amount, :currency].each do |attribute|
            column_present, _, *opts = OptionsExtractor.extract attribute, :no_table, accessor, options
            column(*opts) if column_present
          end
        end

        # Removed for brevity
      end
    end
  end
end

无论通过什么传递给货币化，它似乎总是抛出同样的错误。我真的很想知道我做错了什么，所以任何帮助都会非常感激。

你在初学者中做了什么，可能会影响MoneyRails::Configuration#amount_column？看起来OptionsExtractor缺少一些东西。
