小编use*_*203的帖子

我创建了一个提供搜索条件的表单:

    = search_form_for @q do |f|
  %h3
    Search:
  = f.label :category_id
  %br
  = f.collection_select :category_id_eq, Category.all, :id, :name, :include_blank => true
  %br
  = f.label "Sub-Category"
  %br
  = f.collection_select :subcategory_id_eq, Subcategory.all, :id, :name, :include_blank => true, :prompt => "select category!"
  %br
  = f.label "Contains"
  %br
  = f.text_field :title_or_details_cont
  %br
  = f.submit

我希望能够根据Rails Geocoder gem的"Near"功能进行搜索.有没有人知道如何合并现有的范围,或者特别是如何在Meta Search或Ransack中使用"近"范围？

到目前为止,我的所有尝试都是徒劳的.
