數據傳遞

Question

當我提交表單：

Parameters: {"authenticity_token"=>"LJ/ZME2lHZ7VwCDgPKX6OFe326fXSXo5UB4M0cPwbCE=", "project_id"=>"second", "utf8"=>"✓", "commit"=>"Add Todo", "esthour"=>{"rfp_id"=>"2", "cms_est_hours"=>"", "modul1hours_attributes"=>{"0"=>{"module_est_hours"=>"11", "modul1_id"=>"3"}, "1"=>{"module_est_hours"=>"111", "modul1_id"=>"4"}}, "designpages_est_hours"=>"", "ecommerce_est_hours"=>""}} 

模型

class Esthour < ActiveRecord::Base 
    has_many :modul1hours 
    accepts_nested_attributes_for :modul1hours 
end 

class Modul1hour < ActiveRecord::Base 
    belongs_to :esthour 
    attr_accessible :module_est_hours,:module_act_hours,:modul1_id,:esthour_id 
end 

視圖

<% @m1.map(&:id).each do |id|%> 

    <%= b.fields_for :modul1hours, @esthour.modul1hours.build do |f| %> 

    <%= f.hidden_field :modul1_id, :value => id %> 

    <%= f.text_field :module_est_hours, :size => 30 %> 
    </tr> 
    <% end %> 

<% end %> 

控制器

def new 
    @esthour = Esthour.new 
    @project = params[:project_id] 
    respond_to do |format| 
    format.html # new.html.erb 
    format.json { render :json => @esthour } 
    end 
end 

你可以看到我前面的問題就this。

我在等待有價值的回覆。謝謝。

你應該在你Esthour模型添加：

attr_accessible :modul1hours_attributes
