我有一个设置表单，在传递数据和保存数据时遇到了一些问题。
我有以下代码
路线

get 'settings', to: 'settings#index'
put 'settings', to: 'settings#update_all'

控制器

def index
end

def update_all
  params[:setting].keys.each do |index, value|
    setting = Setting.find_by(name: index)

    if setting
      setting.value = value
      setting.save
    end
  end
end

private

def setting_params
  params.permit(

数据库结构

错误：

NoMethodError at /settings
undefined method `model_name' for {"quote_format"=>"QU-%5n", "quote_value"=>1, "company_name"=>"Your Business Name", "company_address_1"=>"Address Line 1", "company_address_2"=>"Address Line 2", "company_address_3"=>"Address Line 3", "company_address_4"=>"Address Line 4", "company_postcode"=>"Postcode", "company_main_contact"=>"Your Name", "company_main_telephone"=>"Your Telephone Number", "company_main_fax"=>"Your Fax Number", "company_main_mail"=>"Your e-Mail", "company_accounts_contact"=>"", "company_accounts_telephone"=>"", "company_accounts_fax"=>"", "company_accounts_mail"=>"", "company_web_site"=>"Your Web Site", "company_incorporation_status"=>true, "company_registration_number"=>"", "company_corporation_tax_number"=>"", "company_paye_tax_number"=>"",

这是一个遗留应用程序，我刚刚重新构建了表单，并试图让它再次工作。db结构很奇怪，就我个人而言，我会正确地使用activerecord:：store来实现这一点，但由于我们无法更改db中的任何内容，这是不可能的。
如果有人有什么想法那就太好了。
编辑：经过上述更改后，我现在有以下内容

NoMethodError at /settings
undefined method `keys' for nil:NilClass

Hint: Something is `nil` when it probably shouldn't be.

在玩了几天的代码之后，以下是有效的方法。
形式

<%= form_with(model: setting, scope: :settings, method: :post, multipart: true) do |f| %>

控制器

def index
  settings = {}

  Setting.all.each do |setting|
    settings[setting.name] = setting.value
  end

  @settings = OpenStruct.new(settings)
end

def update
  @errors = []
  @error_list = []

  params[:settings].each do |name, value|
    setting = Setting.find_by(name: name)
    next unless setting.present?

    setting.update(value: value)
  end

  redirect_to settings_path, notice: 'Settings have been updated'
end

现在，让错误和其他字段正常工作。
