Question

在这种情况下，我可以将值插入Member表和Club表。但是:task表中有一个名为memberships的字段，我要向其提交值，并且在成员资格表member_id和club_id中由Rails自动插入。如何在下面的表单中加入task字段？提前谢谢。

查看/形式：

<%= form_for @member ,:url=>{:action =>"create"} do |f| %>
  <%= f.text_field :email %>
  <%= f.fields_for :clubs do |s| %>
    <%= s.text_field :name %>
  <% end %>
  <%= f.submit "submit" %>
<% end %>

模型

class Member < ActiveRecord::Base
  has_many :clubs ,:through=> :memberships
  has_many :memberships
  accepts_nested_attributes_for :clubs 
  attr_accessible :clubs_attributes
end

class Club < ActiveRecord::Base
  has_many :members ,:through=>:memberships
  has_many :memberships
end

class Memberships < ActiveRecord::Base
  belongs_to :Member
  belongs_to :Club
end

Answer 1

<%= f.fields_for :memberships do |m| %>
  <%= m.text_field :task %>
  <%= m.fields_for :clubs do |s| %>
    <%= s.text_field :name %>
  <% end %>
<% end %>
