[英]passing dynamic params field
Im working with Rails 3.0.3 我正在使用Rails 3.0.3
I want to create bills in my App. 我想在我的应用程序中创建账单。 Each Bill has many entries (Material, how much of that and the Price)
每个法案都有很多条目(材料,数量和价格)
The Problem i have, is that i want to write the bill and the entries and then save both at the same time. 我的问题是我想写账单和分录,然后同时保存两者。 So when you click on save Bill, the Bill + each Entry should be created (saved in the db).
因此,当您单击保存帐单时,应创建帐单+每个条目(保存在数据库中)。
I can write the bill + each entry (with javascript), but i dont know how i could save both of them. 我可以写账单+每个条目(使用javascript),但我不知道如何保存它们。 Right now i can only save the bill it selft.
现在,我只能保存自己的账单。 Is it possible to pass a dynamic field via params so i can handle that in the bills controller to save?
是否可以通过参数传递动态字段,以便我可以在票据控制器中进行处理以进行保存? How would you implement this?
您将如何实施?
What you are looking for is called nested form, you have a main form for your bill and multiple forms that are dynamically generated as children of this general form using fields_for like this: 您要查找的内容称为嵌套表单,您有一个主表单用于帐单,还有多种表单,这些表单是使用fields_for作为该常规表单的子级动态生成的,如下所示:
<% form_for @bill do |f| %>
<%= f.error_messages %>
<p>
<%= f.label :name %><br />
<%= f.text_field :name %>
</p>
<% f.fields_for :entry do |builder| %>
<%= render "entry", :f => builder %>
<% end %>
<p><%= f.submit "Submit" %></p>
<% end %>
Of course you will need some js for the dynamic creation of the different entries, here you have a couple of railscasts that will be helpfull. 当然,您将需要一些js来动态创建不同的条目,在这里,您会遇到一些有用的railscasts。
