我正在努力弄清楚如何在 Rails 5 中使用简单的表单,以便我可以在我的表单中显示完整的错误消息。我得到的只是顶部的一个框,上面有一条消息:
Please review the problems below:
而不是问题列表或任何突出显示的表单字段 - 我没有得到任何东西。
我已遵循 this post 中的建议并将我的初始化程序中对错误的所有引用替换为“full_error”,但这只能解决父表单的问题 - 嵌套字段仍然只会收到不完整的错误消息。有谁知道如何识别简单形式的错误?

最佳答案
看起来您在错误显示代码中混淆了 haml 和 erb。
这个:
<% @proposal.errors.full_messages.each do |msg| %>
<%= li= msg %>
<% end %>
应该看起来更像这样:
<% if @proposal.errors.any? %>
<ul>
<% @proposal.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
<% end %>
我猜您正在使用 Cocoon,因此您需要正确设置它,但在使用 Rails 5 时会遇到问题。
您的模型中需要类似以下内容:
class Proposal < ApplicationRecord
has_many: :ethics, inverse_of: :proposal
accepts_nested_attributes_for :ethics ...
...
和
class Ethic < ApplicationRecord
belongs_to :proposal, inverse_of: :ethics
...
注意 has_many .. inverse_of 子句,它解决了 Rails 5 中的一个错误。
如果您正确设置了 accepts_nested_attributes_for 子句,我认为 @proposal.errors 应该包含表单的所有错误。
