postgresql - 如何使用多个键和值 rails 5 将数据存储在 hstore 数据类型中

Question

views/_form.html.erb

Extra fee field name : <%= text_field_tag :extra_fee_field,nil, placeholder: 'Enter field name',name: "payment_plan[payment_fees[extra_fee_field]][]" %>fees 
Extra fee value : <%= text_field_tag :extra_fee_value,nil, placeholder: 'Enter fee value in %',name: "payment_plan[payment_fees[extra_fee_value]][]" %> %
<%= submit_tag "Add",id: "add" %>

controllers/payment_plan_controller.rb

def create
@payment_plan = PaymentPlan.new(payment_plan_params)
@payment_plan.save

结束

private
def payment_plan_params
    params.require(:payment_plan).permit(:pay_within_days,:display_active,
    :payment_fees=>[:extra_fee_field=>[],:extra_fee_value=>[]])
end

模型/payment_plan.rb

class PaymentPlan < ApplicationRecord
store_accessor :payment_fees
end

以下格式的数据存储:-

payment_fees: {"extra_fee_field"=>"[\"serfere\",\"sfsdfdff\"]", "extra_fee_value"=>"[\"5\",\"7\"]"}, display_active : false, created_at: "2016-07-12 06:41:48", updated_at: "2016-07-12 06:41:48">

请帮帮我。 提前致谢..:)

在尽了最大努力之后，我得到了解决方案，上面所有的代码都是正确的，只是改变了 Controller 的方法

@extra_fee_field = params[:payment_plan][:payment_fees][:extra_fee_field]
@extra_fee_value = params[:payment_plan][:payment_fees][:extra_fee_value]
@payment_plan[:payment_fees] = @extra_fee_field.zip(@extra_fee_value).to_h

在此之后我可以将数据存储在 hstore 数据类型中
