我正在开发一个遗留应用程序，我正在重构设置，我们有一个奇怪的数据库结构，但由于现有数据无法更改。
我遇到的问题如下，设置是使用 db:seed 这很好，但是，我不能进入表单并更新它们。
以下是我到目前为止所拥有的（文件长度缩短）
表单在索引中，所以我将所有内容移到了该方法中，并注解掉了所有遗留代码
控制器

作为一个测试，这是我尝试过的。
我补充说 @settings = Setting.new 索引给了我一个未定义的方法错误，所以在模型中我添加了以下内容

def company_name
  Setting.find_by(name: :company_name).value
end

它使用正确的公司名称呈现页面，但是，有135个设置，因此我需要一种方法来保存所有设置。

我建议您在模型上添加一个类方法：

def self.value_for(setting)
  Setting.find_by(name: setting).try(:value)
end

设定 value 字段上的属性：

f.text_field :company_name, value: Setting.value_for(:company_name)
f.number_field :quote_value, value: Setting.value_for(:quote_value)

它并不完美，但非常清晰易读，这在遗留代码中很重要
在控制器中，类似的操作应该完成以下工作：

def update
  # Do some checks if you want

  params[:settings].each do |setting, value|
    next if unallowed_setting(setting) # create unallowed_setting method if you need a filter, remove this line otherwise

    model = Setting.find_or_initialize_by(name: setting)
    model.value = value
    model.save!
  end

  redirect_to :index
end

编辑
另一种可能是保留旧代码并将@settings设置为openstruct示例，这样您就不必在视图中设置值，但我不能100%确定它是否有效：

def index
  settings = {
    id: nil # I think this would be needed
  }
  Setting.all.each do |setting|
    settings[setting.name] = setting.value
  end
  @settings = OpenStruct.new(settings)
end
