我甲肝这在我的store_opening_stock形式更新2款一次与Ruby on Rails中相同的属性
<%= simple_form_for @store_opening_stock do |f| %>
<%= f.error_messages %>
<p>
<%= f.hidden_field :user_id, :value => current_user.id %>
<%= f.label :employee_id %>
<%= f.collection_select :employee_id, Employee.all, :id, :name, options ={:prompt => "-Select employee Name"}, :class => "employee name", :style=>'width:210px;'%><br />
<%= f.label :date %>
<%= f.datepicker :date, :dateFormat => 'dd MM, yy', :showOn => "both", :buttonImage => "/assets/calendar.gif", :buttonImageOnly => true, :changeMonth => true, :changeYear => true, :placeholder => "Click on the calender", :yearRange =>'1950:2042' %><br/>
<%= f.label :product_id %>
<%= f.collection_select :product_id, Product.all, :id, :title, options ={:prompt => "-Select Product Name"}, :class => "product name", :style=>'width:210px;'%><br />
<%= f.input :batch_no, :label => 'Batch No', :input_html => { :size => 30}%><br/>
<%= f.input :price, :label => 'price', :input_html => { :size => 30}, :placeholder =>'Enter Digits'%><br/>
<%= f.input :quantity, :label => 'quantity', :input_html => { :size => 30}, :placeholder =>'Enter Digits'%><br/>
<p><%= f.submit %></p>
<% end %>
,我有2个型号,一个是store_opening_stock.rb和stock.rb
class StoreOpeningStock < ActiveRecord::Base
attr_accessible :comments_attributes, :stocks_attributes
attr_accessible :user_id, :date ,:store_location_id, :product_id, :batch_no
attr_accessible :expiry_date, :price, :quantity, :comment_id, :employee_id
attr_accessible :goods_receipt_id
has_many :stocks
end
class Stock < ActiveRecord::Base
attr_accessible :date, :store_location_id, :product_id, :batch_no, :expiry_date, :price, :quantity, :goods_reciept_id
belongs_to :store_opening_stock, :foriegn_key => "store_opening_stock_id"
acts_as_store_opening_stock
accepts_nested_attributes_for :store_opening_stocks
end
end
有没有办法可以更新产品的价格,PRODUCT_ID,数量,批次号从store_opening_stocks尽快股票作为我点击提交在store_opening_stock形式?????我可以一次更新2个表格,因为我在轨道上按下提交Ruby? 在此先感谢
的NiMesh做到这一点我m是一有点困惑。抱歉,我对这个框架感兴趣,请问field的for如何帮助我更新这两个表中的'price',同时使用一种形式? – bharath
请参考上面的'fields_for'文档链接,并向下滚动到'一对多'部分,这是与您的要求最相似的部分。一旦你插入“股票”模型的价格输入字段表单,它们将自动在你的数据库保存store_opening_stock当创建 –
经历了,非常感谢的NiMesh。 – bharath
