为对象的动态部分名称 [英] Dynamic partial name for an object

问题描述

 渲染@some_object
 

将呈现 Rails.root /应用/视图/ some_objects / _some_object.html.erb

现在我要处理这部分将被渲染取决于其 DATA_TYPE 字段。例如：

 类SomeObject＆LT; AR :: Base的
  ＃一些难懂的方法至极我需要重写
  高清partial_name
    案例DATA_TYPE
    当字符串
      string_template
    在文本
      text_template
    其他
      blank_template
    结束
  结束
结束
 

我知道有 MODEL_NAME ， i18n_key 和一些其他国家，这是returnes型号名称，但哪一个是在我的渲染@object使用情况？

修改

现在我已经停在一个没有触及模式最简单的解决方案。我删除了所有这种逻辑到 _some_object.html.erb 部分，所以它呈现的部分我需要自身内部：

 ＆LT; D​​IV CLASS ='claim_template_field'＆GT​​;
  ＆其中;％=渲染/some_objects/#{f.object.data_type.downcase}_template，：F =＆GT; F％＆GT;
＆LT; / DIV＆GT;

render @some_object

will render Rails.root/app/views/some_objects/_some_object.html.erb

Now I want to handle which partial will be rendered depends on its data_type field. For example:

class SomeObject < AR::Base
  # some magick method wich I need to rewrite
  def partial_name
    case data_type
    when "String"
      "string_template"
    when "Text"
      "text_template"
    else
      "blank_template"
    end
  end
end

I know there is model_name, i18n_key and some others, which are returnes model name, but which one is used in my render @object case?

EDIT

Now I've stopped on the easiest solution that didn't touch models. I removed all this logic into _some_object.html.erb partial, so it renders partial I need inside of itself:

<div class='claim_template_field'>
  <%= render "/some_objects/#{f.object.data_type.downcase}_template", :f => f %>
</div>
