ruby on rails项目中的多个嵌套窗体

Question

我尝试在一个表单中使用多个嵌套属性，尽管似乎只出现了第一组属性。

下面是HAML模板

.mdl-cell.mdl-cell--10-col.mdl-cell--1-offset
  %h3.mdl-typography--display-1= t('.account_title')
  = form.fields_for :address do |address_fields|
    .mdl-grid
      .mdl-textfield.mdl-js-textfield.mdl-textfield--floating-label.mdl-cell.mdl-cell--6-col
        = address_fields.text_field :first_name, class: 'mdl-textfield__input'
        = address_fields.label :first_name, class: 'mdl-textfield__label'
      .mdl-textfield.mdl-js-textfield.mdl-textfield--floating-label.mdl-cell.mdl-cell--6-col
        = address_fields.text_field :last_name, class: 'mdl-textfield__input'
        = address_fields.label :last_name, class: 'mdl-textfield__label'
      .mdl-textfield.mdl-js-textfield.mdl-textfield--floating-label.mdl-cell.mdl-cell--6-col
        = form.text_field :name, class: 'mdl-textfield__input'
        = form.label :name, class: 'mdl-textfield__label'
      .mdl-textfield.mdl-js-textfield.mdl-textfield--floating-label.mdl-cell.mdl-cell--6-col
        = form.email_field :email, class: 'mdl-textfield__input'
        = form.label :email, class: 'mdl-textfield__label'
  %h3.mdl-typography--display-1= t('.bank_title')
  = form.fields_for :account do |account_fields|
    .mdl-grid
      .mdl-textfield.mdl-js-textfield.mdl-textfield--floating-label.mdl-cell.mdl-cell--6-col
        = account_fields.text_field :bsb, class: 'mdl-textfield__input'
        = account_fields.label :bsb, class: 'mdl-textfield__label'
      .mdl-textfield.mdl-js-textfield.mdl-textfield--floating-label.mdl-cell.mdl-cell--6-col
        = account_fields.text_field :account_number, class: 'mdl-textfield__input'
        = account_fields.label :account_number, class: 'mdl-textfield__label'
      .mdl-textfield.mdl-js-textfield.mdl-textfield--floating-label.mdl-cell.mdl-cell--12-col
        = account_fields.text_field :account_name, class: 'mdl-textfield__input'
        = account_fields.label :account_name, class: 'mdl-textfield__label'

模型中的定义

accepts_nested_attributes_for :address, reject_if: proc { |attributes| attributes['address1'].blank? }
  accepts_nested_attributes_for :trading_hours
  accepts_nested_attributes_for :phones, :reject_if => lambda { |t| ( t['display_number'].gsub(/\D+/, '').blank?) }
  accepts_nested_attributes_for :account

Answer 1

在父表单上，您需要为表单构建每个附加属性(这是一个新表单，我相信您可以在def new ...下的控制器中完成此操作)

def new
  @parent.address.build
  @parent.trading_hours.build
  @parent.phones.build
  @parent.account.build
end

如果你不想做一个新的表单，请让我知道并更新问题
