Rails - 简单形式Bootstrap - 显示内联错误全文(或任何地方)
我很想弄清楚如何在rails 5中使用简单形式,以便在窗体中显示完整的错误消息。我得到的是在与消息顶部,上面写着一个盒子:Rails - 简单形式Bootstrap - 显示内联错误全文(或任何地方)
Please review the problems below:
相反的问题的列表或任何突出显示的表单字段 - 我什么也得不到。
我按照this post的建议,用'full_error'替换了我的初始化程序中的所有错误引用,但这只能解决父窗体的问题 - 嵌套字段仍然只是得到一个不完整的错误消息。有谁知道如何识别简单形式的错误?

它看起来像你得到HAML和再培训局在错误显示的代码混淆。
此:
<% @proposal.errors.full_messages.each do |msg| %>
<%= li= msg %>
<% end %>
应该看起来更像是这样的:
<% if @proposal.errors.any? %>
<ul>
<% @proposal.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
</ul>
<% end %>
我猜你使用的蚕茧,所以你需要正确设置了,但有一个疑难杂症时使用Rails 5.
您的模型中需要如下内容:
class Proposal < ApplicationRecord
has_many: :ethics, inverse_of: :proposal
accepts_nested_attributes_for :ethics ...
...
和
class Ethic < ApplicationRecord
belongs_to :proposal, inverse_of: :ethics
...
注意的has_many .. inverse_of条款,工作轮在导轨5的错误。
如果您正确设置了accepts_nested_attributes_for子句,我认为@project.errors应包含表单的所有错误。
你对伦理模型的反面的东西是正确的 - 这使得错误消失了,但是我如何打印错误中的道德属性伦理形式的嵌套部分?他们在表格顶部列出了错误提案列表,但是当我向下滚动到道德属性时,我得到的所有信息都是红色方框,请回顾下面的问题,然后再列出没有列表。 – Mel
我不认为有一种明显的方式来分裂父母和孩子的错误。我会从simple_fields_for块中移除“”行,并依靠simple_form生成错误消息。顺便说一句,Sravan说你的simple_fields_for块需要一个不同的变量。 –
但它实际上工作正常与f:f - 我不知道我确实需要它。这些属性是使用f创建的(与提议相同)。 – Mel
我在你的代码中发现的第一个错误是,在你的嵌套字段,你已经采取了相同的变量f
该参数可能会受到母体参数的影响10之三f
所以,
嵌套会,
<%= f.simple_fields_for :ethics do |ff| %>
<%= ff.error_notification %>
<%= render 'package/ethics/ethics_fields', f: f %>
<% end %>
现在的形式,
<%= simple_form_for(@proposal) do |f| %>
<%= f.error_notification %>
<% @proposal.errors.full_messages.each do |msg| %>
<%= li= msg %>
<% end %>
<div class="form-inputs" style="margin-bottom: 50px">
<!-- General Organisation details -->
<div class="row">
<div class="col-md-12">
<%= f.input :title, :label => "Title" %>
</div>
</div>
<div class="row">
<div class="col-md-12">
<%= f.input :byline, :label => "Tagline" %>
</div>
</div>
<div class="row">
<div class="col-md-12">
<%= f.input :description, as: :text, :label => "Outline your proposal", input_html: { rows: 15 } %>
</div>
</div>
<!-- Package: :ethics considerations -->
<div class="row">
<div class="col-md-12">
<div class="form_title">Research Ethics</div>
</div>
</div>
<div class="row">
<div class="col-md-12">
<%= f.simple_fields_for :ethics do |ff| %>
<%= ff.error_notification %>
<%= render 'package/ethics/ethics_fields', f: ff %>
<% end %>
<%= link_to_add_association 'Add another ethics issue', f, :ethics, partial: 'package/ethics/ethics_fields' %>
</div>
</div>
</div>
<div class="row">
<div class="col-md-10 col-md-offset-1" style="margin-top: 50px">
<div class="form-actions">
<%= f.button :submit %>
</div>
</div>
</div>
<% end %>
<%= f.simple_fields_for :ethics do |ff| %>
<%= ff.error_notification %>
<%= render 'package/ethics/ethics_fields', f: ff %>
<% @proposal.ethics.errors.full_messages.each do |msg| %>
<%= li= msg %>
<% end %>
<% end %>
编辑:即使上面没有解决问题,
尝试从获取ethics object
中的错误可变
所以,
<%= f.simple_fields_for :ethics do |ff| %>
<%= ff.error_notification %>
<% @proposal.ethics.errors.full_messages.each do |msg| %>
<%= li= msg %>
<% end %>
<%= render 'package/ethics/ethics_fields', f: f %>
<% end %>
另一种选择是直接在现场显示错误消息。
<%= f.input :title, :label => "Title", id:"title" %>
<%= f.error :title, :id => "title_error" %>
这将显示标题字段旁标题的错误信息。您可以将f.error方法添加到表单中的每个字段,而不是在表单上方显示<ul>
,或者在表单上方显示<ul>
。
对于nested_form_fields,尝试将validates_associated :assoc_model_name
添加到主模型中。这也会为关联的模型运行验证。
这应该会使用simple_form gem自动发生。它甚至包括相关字段所需的错误。 –
请粘贴您的表单。 – Sravan
添加表格上面 – Mel
