Ruby on rails 如何保存对模型的响应

我试图将此响应从API保存到模型字段。我不能保存它，因为mongoid说这不是字符串。我尝试将其保存为数组和散列。不走运

我怎样才能正确地将它保存在一个字段中，或者正确地格式化它，这样我就可以将它保存为一个数组或散列，这样我就可以稍后调用它。我想可能是这样的，但感觉不对

transactions.rb

    field :accounts,        type: Array.new
    ...

    def account_pull
       accounts_response = Api.set_user(access_token, ['auth'])    
       self.accounts = accounts_response.accounts
       model.save
    end
end

下面是我得到的完整回复的一个示例

试试这段代码

将accounts字段类型更改为hash

class Transactions
  include Mongoid::Document
  field : accounts :type => Hash
end

然后，可以在转换为哈希后保存响应

  def account_pull
   response = Api.set_user(access_token, ['auth'])
   accounts = response.accounts
   accounts_hash = Hash[accounts.map.with_index { |x, i| [i, x] }]
   self.accounts = accounts_hash
   self.save
 end

您的响应既不是字符串，也不是数组或散列：它是一个API:：User，其数组为API:：Account

也许使用as_json将其转换为简单的结构就可以做到这一点：

model.user = api_user.as_json
model.save

或者，您可以尝试获得初始响应，以避免许多转换（如果可能）
