NoMethodError: undefined method `liquidity_manager?' for #<Order:0x007fd9b7a4cf98>

Question

我的解决方案抛出 NoMethodError。这是我在下面所做的：

Order.rb

class Order < ActiveRecord::Base
  belongs_to :member
end

Member.rb

class Order < ActiveRecord::Base
  has_many :orders

  def liquidity_manager?
    @is_liquidity_manager ||= self.class.liquidity_managers.include?(self.email)
  end

  def liquidity_managers
    ENV['LM_ACCOUNTS'].split(',')
  end
end

rake 任务逻辑

lib/update_order_tags.rake

中的逻辑

num_counts = (Order.count/10).ceil
num_counts.times do |i|
  Order.all.offset(i*10).limit(10).find_each do |g|
    if g.tags.blank? # am saving on only the blank fields
      if g.liquidity_manager? # The error is here
        g.tags = 'LM'
        g.save!
      else
        g.tags = 'Customer'
        g.save!
      end
    end
  end
end

如何在 lib 中引用对我有用的 liquidity_manager? 方法？

Answer 1

您在 Member.rb 中定义了 Order#liquidity_manager?，Rails 不会自动加载它。您必须显式加载文件 Member.rb，或将该文件重命名为 /app/models/order.rb.

Answer 2

所以根据@sawa 在回答部分给我的建议，以下是我为使其工作所做的工作。

num_counts = (Order.count/10).ceil
num_counts.times do |i|
  Order.all.offset(i*10).limit(10).find_each do |g|
    if g.tags.blank? 
      if g.member.liquidity_manager? # So this easily gets to Member.rb to reference liquidity_manager? method.
        g.tags = 'LM'
        g.save!
      else
        g.tags = 'Customer'
        g.save!
      end
    end
  end
end
