Question

我正在寻找一种管理表单中多个嵌入对象的方法。

找到了一个由bowsersenior开发的一种解决方案

Formtastic with Mongoid embedded_in relations

但我无法对simple_form

做同样的事情

formtastic：

= semantic_form_for @team do |form|
  = @team.players.each do |player|
    = form.inputs :for => [:players, player] do |player_form|
      = player_form.input :name

最好的问候

样品

class Team
  include Mongoid::Document
  field :name, :type => String
  embeds_many :players
end

class Player
  include Mongoid::Document
  embedded_in :team, :inverse_of => :players
  field :name, :type => String
  field :active, :type=> Boolean # checkboxes
end

Answer 1

不确定这是否有效，但你可能想尝试这样的事情：

= simple_form_for @team do |form|
  = f.input :name
  = f.simple_fields_for @team.players do |player_form|
    = player_form.input :name

请记住，在表单出现之前，您必须在团队中创建一个新玩家。在您的控制器（控制器）中：

def new
  @team = Team.new
  8.times { @team.players.new } #for 8 players
end

mongoid，embedy_many，simple_form
