我有以下嵌套形式:
<%= form_for @contrat,:url => backend_orders_update_report_url(@contrat) do |f| %>
<%= f.fields_for :contrat_lines do |fcl| %>
<%= fcl.object.inspect %>
<% end %>
<% end %>
输出如下:
nil
在嵌套表单中,我想显示一些元素,而不是作为表单,而是作为原始文本和一些作为表单字段。通常通过执行 f.object.name 以一种形式,我会访问该名称并能够根据需要显示它。但是,如果我在这里执行 fcl.object,则只有 nil。它应该显示对 contrat_line 对象的检查。
是否可以以嵌套形式访问数据?
编辑 :
控制器动作:
def show_report
@contrat = Contrat.find(params[:id])
end
以下是模型在开始时的关系:
对比线:
class ContratLine < ActiveRecord::Base
include Priceable
belongs_to :contrat
belongs_to :good
#a enlever ici et dans la base
attr_accessible :active_start,:active,:good_id,:pricing,:contrat
validates :active_start, :presence=> true,:if => "active"
validate :active_start_smaller_than_active_stop
validate :active_start_day_cannot_be_greater_than_28
has_one :pricing, :as => :priceable, :dependent => :delete
before_validation :convert_month_year_to_date
after_save :set_user_subscription_date
对比:
class Contrat < ActiveRecord::Base
has_many :contrat_lines, :dependent => :delete_all
belongs_to :user
attr_accessible :user_id,:pricing_id,:state,:adresse_id,:adresse,:payment,:adresse_attributes,:automatic,:start_date,:end_date
