Rails i18n and yml structure for form labels
提问by rhardih
According to the ActionView documentation. Quote:
根据ActionView 文档。引用：
The text of label will default to the attribute name unless a translation is found in the current I18n locale (through views.labels.<modelname>.<attribute>) or you specify it explicitly.
标签文本将默认为属性名称，除非在当前 I18n 语言环境中找到翻译（通过 views.labels.<modelname>.<attribute>）或者您明确指定它。
I have a "user" model and a registration form. Here's a snippet of the relevant part:
我有一个“用户”模型和一个注册表单。这是相关部分的片段：
<% form_for(@user) do |f| %>
...
<p>
<%= f.label :username %>
<%= f.text_field :username, :class => 'full_width' %>
</p>
...
<% end %>
Dots hide unimportant code.
点隐藏了不重要的代码。
As I understand the documentation, if I provide a translation in my locale file, in this case :dk, my dk.yml looking like so:
据我了解文档，如果我在我的语言环境文件中提供翻译，在这种情况下：dk，我的 dk.yml 看起来像这样：
dk:
views:
labels:
user:
username:
"blahblah"
Rails should translate the label text and insert "blahblah" instead of "Username".
Rails 应该翻译标签文本并插入“blahblah”而不是“用户名”。
This is not happening, so I must have missed something. Any help appreciated.
这不会发生，所以我一定错过了什么。任何帮助表示赞赏。

In Rails 3.1 that is a little bit changed.
在 Rails 3.1 中，这有点改变。
<% form_for @post do |f| %>
<%= f.label :title %>
<%= f.text_field :title %>
<%= f.submit %>
<% end %>

helpers:
label:
post:
title: 'Customized title'

I think I found another solution here.
我想我在这里找到了另一个解决方案。
My app was version 2.3.5. I've now changed it to 2.3.8 and <%= f.label :username %>now uses the translation in:
我的应用程序是 2.3.5 版。我现在已将其更改为 2.3.8，<%= f.label :username %>现在使用以下翻译：
dk:
activerecord:
attributes:
user:
username:
I found the hint in this ticket:

That's because the labelmethod you are calling is not the one from ActionView::Helpers::FormHelperbut is in fact the label_tagmethod from ActionView::Helpers::FormTagHelper. The form_formethod is rewriting the code in the given block by adding _tagto the used form helpers. So you're not looking at the documentation for the right method!
那是因为label您调用的方法不是 fromActionView::Helpers::FormHelper的label_tag方法，但实际上是from的方法ActionView::Helpers::FormTagHelper。该form_for方法通过添加_tag到使用的表单助手来重写给定块中的代码。所以你不是在看正确方法的文档！
I've not yet used that method, as sometimes the label for a field can be different from multiple forms using the same model, so I've written my own helper.
我还没有使用过这种方法，因为有时一个字段的标签可能与使用相同模型的多个表单不同，所以我编写了自己的助手。
