Rails I18n 翻译范围

Cyr*_*ris 5 ruby scope ruby-on-rails erb rails-i18n

编写一个完全翻译的应用程序可能会变得乏味。有没有办法为当前上下文设置默认翻译范围?

示例:我在我的show.html.erb操作中的部分_deadlines.html.erb中写入ProjectsController

现在,因为我正在努力成为一名优秀的程序员,所以我正在确定我所有的翻译。我想生成以下树

projects:
  deadlines:
    now: "Hurry the deadline is today !"
    ....

我怎样才能让它比每次写全范围更不乏味?

项目/show.html.erb

...
<%= render 'projects/deadlines', project: @project %>
...

show.html.erb调用的projects/ _deadlines.html.erb

<p>Deadline : <%= t(:now, scope: [:projects, :deadlines]) %></p>

有没有办法为当前上下文设置默认范围(这里是整个_deadlines.html.erb文件)?

编辑

有些人建议使用 Rails Lazy lookup,但这不会产生我正在寻找的范围。就我而言,我想跳过action默认范围(显示、索引等...)并为我正在渲染的当前部分添加一个范围(在我的情况下为 _deadlines.html.erb)

Rails 懒惰查找:

t('.now')
<=> t(:now, scope: [:projects, :show]

但我想要:

t('.now')
<=> t(:now, scope: [:projects, :deadlines]

Rails 实现了一种在视图中查找语言环境的便捷方法。当您有以下字典时:

es:
  projects:
    index:  # in 'index.html.erb' template file
      title: "Título"
    deadlines:  # in '_deadlines.html.erb' partial file
      title: "Fecha límite"

您可以按如下方式查找这些值:

# app/views/projects/index.html.erb
<%= t '.title' %>  # => "Título"

# app/views/projects/_deadlines.html.erb
<%= t '.title' %>  # => "Fecha límite"

好吧,我实际上对此仍然不满意。当你想在不同的地方翻译相同的东西时,这个默认的“惰性查找”范围完全是错误的。假设我有两个不同的部分,其中包含处理同一模型的信息。使用惰性查找,我需要在 yml 文件中进行两次相同的翻译。

这里有一小段代码,您可以将其放入应用程序助手中。它基本上是默认 I18n.t 的覆盖,将范围设置为@t_scope定义时的范围,您无需再担心范围

我的代码添加

助手/application_helper.rb

def t(*args)
  # If there is just one param and we have defined a translation scope in the view
  # only using symbols right now, need extended version to handle strings
  if args.size == 1 and args.first.is_a?(Symbol) and @t_scope
    super(args.shift, @t_scope)
  else
    super(*args)
  end
end

def set_t_scope(scope)
  push_t_scope(@t_scope ||= {})
  replace_t_scope(scope)
end
alias :t_scope :set_t_scope

def replace_t_scope(scope)
  @t_scope = {scope: scope}
end

def push_t_scope(scope)
  (@tscope_stack ||= []) << scope
end

def pop_t_scope
  @t_scope = @tscope_stack.pop
end

你可以用它做什么

项目/show.html.erb

<%= t_scope([:projects, :deadlines]) %>
<fieldset>
  <legend>Deadlines</legend>
  <% if Time.now > @project.deadline.expected_finish_date %>
  <p><%= t(:hurry) %></p>
  <% else %>
  <p><%= t(:you_have_time) %>
</fieldset>
<fieldset>
  <legend>Deadlines</legend>
  <%= render 'tasks', tasks: @project.tasks %>

视图/项目/_tasks.html.erb

<%= t_scope([:projects, :tasks]) %>
  <% tasks.each do | task| %>
  <h2><%= t(:person_in_charge) %></h2>
  ...
<% pop_t_scope %>

en.yml

en:
  projects:
    deadlines:
      hurry: "Hurry man !"
      you_have_time: "Relax, there's still time"
    tasks:
      person_in_charge: 'The Boss is %{name}'

现在我看到的唯一问题是,当从视图渲染多个部分时,@t_scope 将被传输,并可能导致问题。不过,在每个文件的开头将 @t_scope 设置为 nil 不会有问题
