使用带有 form_tag 且无模型的 country_select gem [英] Using country_select gem with form_tag and no model

问题描述

我在 Rails 4 的表单标签中使用 country_select gem:

I am using the country_select gem in Rails 4 in a form tag:

<%= form_tag(@url, method: :post, class: "form-horizontal") do %>
    <div class="form-group">
      <%= label_tag(:country_code, "Country code") %>
      <%= country_select :country_code, @country_code, class: "form-control" %>
    </div><% end %>

我收到以下错误.

undefined method `NZ' for "NZ":String

这是一个安静的异常错误，我没有发现 country_select gem 的任何其他实例.rails 应用程序没有数据库并且正在与外部数据库通信，因此该应用程序中没有模型.有人建议我使用 Open Struct 来解决这个问题.但是，我想知道有没有人知道更快的解决方法?表单正在获取数据库中的数据！

This is a quiet unusual error and I have not found any other instances of it for the country_select gem. The rails application does not have a database and is communicating to an external database so there are no models in this application. I have been suggested to use Open Struct to get around this issue. However, I am wondering does anyone know of a quicker fix? The form is picking up the data in the database though!

推荐答案

问题在于我没有模型.我需要使用帮助我模拟对象的 OpenStruct 数据结构.您可以阅读有关它的更多信息 这里

The issue was with the fact that I had no model. I needed to use the OpenStruct data structure which helped me to simulate objects. You can read more about it here
