Question

我正在尝试将此响应从API保存到模型字段。我不能保存它，因为mongoid说这不是一个字符串。我尝试将其保存为数组和哈希。没有运气。

如何正确地将其保存在字段中或正确格式化，以便我可以将其保存为数组或散列，以便稍后调用它。我想可能是这样的但是感觉不对。

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

以下是我收到的完整回复的示例。

#<Api::User:0xb7e9f2c @accounts=[#<Api::Account:0xb7b6eb0 @id="QPO8Jo8vdDHMepg41PBwckXm4KdK1yUdmXOwK", @name=nil, @type="depository", @meta={"number"=>"9606", "name"=>"Bank Savings"}, @institution_type="fake_institution", @available_balance=1203.42, @current_balance=1274.93, @subtype=nil, @numbers={"routing"=>"021000021", "account"=>"9900009606", "wireRouting"=>"021000021"}>, #<Api::Account:0xb7b6ba4 @id="nban4wnPKEtnmEpaKzbYFYQvA7D7pnCaeDBMy", @name=nil, @type="depository", @meta={"number"=>"1702", "name"=>"Bank Checking"}, @institution_type="fake_institution", @available_balance=1081.78, @current_balance=1253.32, @subtype=nil, @numbers={"routing"=>"021000021", "account"=>"9900001702", "wireRouting"=>"021000021"}>, #<Api::Account:0xb7b68e8 @id="XARE85EJqKsjxLp6XR8ocg8VakrkXpTXmRdOo", @name=nil, @type="depository", @meta={"number"=>"5204", "name"=>"Bank Premier Checking"}, @institution_type="fake_institution", @available_balance=7205.23, @current_balance=7255.23, @subtype=nil, @numbers={"routing"=>"021000021", "account"=>"9900005204", "wireRouting"=>"021000021"}>, #<Api::Account:0xb7b66cc @id="pJPM4LMBNQFrOwp0jqEyTwyxJQrQbgU6kq37k", @name=nil, @type="credit", @meta={"limit"=>12500, "number"=>"3002", "name"=>"Bank Credit Card"}, @institution_type="fake_institution", @available_balance=9930, @current_balance=2275.58, @subtype=nil, @numbers={}>], @transactions=[], @permissions=["auth"], @access_token="test_chase", @api_res="success", @info={}, @pending_mfa_questions="", @type=nil>

Answer 1

试试此代码

将帐户字段类型更改为哈希

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

然后您可以在转换为哈希

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

Answer 2

你的回复既不是字符串也不是数组或哈希：它是一个带有API :: Account数组的API :: User。

使用as_json将它转换为一个简单的结构可以解决这个问题：

model.user = api_user.as_json
model.save

或者，您可以尝试获取初始响应，以避免许多转换（如果可能）。
