我有一类项目和组别成员与控制人员之间的单向关系,更新功能如下:
@project = Project.find(params[:id])
@project.update_attributes(params[:project])
现在,我想确定一些领域,在储蓄发生之前,这些领域没有为一些小组成员规定。 我不能像现在这样利用最新情况。
这样做的最佳方式是什么?
Thanks, Nicolas.

我将研究<代码>accepts_nested_attributes_for功能。 也许有这样的东西:
class Project < ActiveRecord::Base
has_one :team
accepts_nested_attributes_for :team
# also this will be useful
validates_associated :team
end
您将使用<代码>-for方法确定你的属性。 这可能看上去:
<% form_for(@project) do |p| %>
<%= p.error_messages %>
<!-- Project name -->
<%= p.text_field :name %>
<% f.fields_for(@project.team) do |t| %>
<!-- Team Name -->
<%= t.text_field :name %>
<% end %>
<%= f.submit Create Project %>
<% end %>
当您提交表格时,您将可打电话@project.update_attributes(params [:project]
,并将工作。 还可raise params.inspect
,以了解如何封条。
希望这一帮助。
