mongoid、embedy_many、simple_form

Question

我正在寻找一种方法来管理表单中的多个嵌入对象。

找到了 bowsersenior 的 formtastic 解决方案

Formtastic with Mongoid embedded_in relations

但我无法对 simple_form 做同样的事情

形式:

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

此致

样本

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

不确定这是否可行，但您可能想尝试以下操作:

= 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，在表格出现之前，您必须在团队中创建一个新玩家。
在您的 Controller ( Controller )中:

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