Rails - 简单形式Bootstrap - 显示内联错误全文(或任何地方)

问题描述:

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?

请粘贴您的表单。 – Sravan

添加表格上面 – Mel

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 ... 
... 

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。 –

+0

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 %>

请检查这个答案,随时问任何疑问。 – Sravan

但如果是这样的话,所有的道德领域将无法正常工作。 f.input在输入元素的部分伦理嵌套字段中工作正常。我无法找到一种方式来显示该形式的错误 – Mel

+0

道德领域无法正常工作,但错误消息可能无法显示。检查答案的最后部分。 – Sravan

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。 –
