向ActiveAdmin添加数值范围过滤 [英] Adding Numeric Range Filtering to ActiveAdmin

问题描述

2015年问候与节日快乐-

Greetings and Happy Holidays 2015 --

我尝试根据 Boris Stall的出色博客文章添加数值范围过滤.

我正在跑步:

• 导轨4.2.4
• Ruby 2.2.3
• ActiveAdmin 1.0.0pre2

我一直遇到此错误:

找不到输入类NumericRangeInput

Unable to find input class NumericRangeInput

这是我的config/initializers/active_admin/filter_numeric_range_input.rb

Here is my config/initializers/active_admin/filter_numeric_range_input.rb

module ActiveAdmin
  module Inputs
    class FilterNumericRangeInput < ::Formtastic::Inputs::StringInput # Add filter module wrapper
      include ActiveAdmin::Inputs::Filters::Base

      def to_html
        input_wrapping do
          [ label_html,
            builder.text_field(gt_input_name, input_html_options(gt_input_name)),
            template.content_tag(:span, "-", :class => "seperator"),
            builder.text_field(lt_input_name, input_html_options(lt_input_name)),
          ].join("\n").html_safe
        end
      end

      def gt_input_name
        "#{method}_gteq"
      end
      alias :input_name :gt_input_name

      def lt_input_name
        "#{method}_lteq"
      end

      def input_html_options(input_name = gt_input_name)
        current_value = @object.send(input_name)
         { :size => 10, :id => "#{input_name}_numeric" , :value => current_value }
      end
    end
  end
end

我只是在尝试:

filter :id, as: :numeric_range

我已经研究了集成AA，Ransack，Formtastic等的潜在问题，但是我还没有足够的能力去知道从这里出发的去向.任何帮助将不胜感激.

I've researched the potential issues integrating AA, Ransack, Formtastic, etc., but I'm not advanced enough to know where to go from here. Any help is greatly appreciated.

推荐答案

看来，较新版本的ActiveAdmin可能有不同的策略来加载或命名输入模块中的其他类.我注意到文件中的类名称称为FilterNumericRangeInput.因此，AA必须采取一些措施来转换名称，我们只需要弄清楚要正确转换的符号即可.因此，作为实验，我尝试将app/admin/test.rb中的符号重命名为:

It seems newer versions of ActiveAdmin might have a different strategy for loading or naming other classes in the input module. I noticed that the class name in the file is called FilterNumericRangeInput. So AA must be doing something to convert the name, we just need to figure out which symbol to give to convert properly. So as an experiment, I tried to rename the symbol in app/admin/test.rb to:

filter :id, as: :numeric_range_2

我得到了错误:

Unable to find input class NumericRange2Input

因此，根据这个提示，我尝试将符号名称更改为:

So with that hint I tried changing the symbol name to:

filter :id, as: :filter_numeric_range

它奏效了.
