Rails 5.1.1 Ruby 2.4.1
创建新组织时，联系信息应保存到联系人表中，但事实并非如此。我对 rails 仍然相对较新，并且已经浏览了其他带有强大参数的帖子，但没有运气。我想我已经包含了所有必要的部分，如果不让我知道，谢谢！

在字段前放置一个f.
= f.fields_for :contact_attributes do |ff|
.field.form-group
= ff.label :Contact_Name, for: :contact_name
= ff.text_field :name, class: 'form-control'
= ff.label :Email, for: :contact_email

.actions = f.submit class: 'btn btn-outline-primary'
如果你看一下参数的形状，你会发现organization和contact_attributes是兄弟姐妹，而不是父嵌套的。这与你的fields_for有关。在我的头顶上，你必须这样做：
= fields_for 'organization[contact_attributes]' do |ff|
或某种形式的：
= fields_for organization.contact do |ff|
尽管在这种情况下，您显然必须确保它不是零。
或者检查@Ramon的答案，我认为他做到了。
您的contact_attributes不是嵌套在组织内部，而是嵌套在organization_params中，您希望contact_attributes嵌套。修复视图，使contact_attributes嵌套在组织中。
在视图中对contract_attributes进行以下更改
f.fields_for :contract do |ff|
