我正在尝试使用传递给控制器的参数来完成简单的排序。我正在关注有关搜索和搜索的文档。在思考 Sphinx 网站时，我遇到了以下错误。我做错了什么？

以下@places对象是think Sphinx类的实例。

 @places = Place.search(params[:q], :order => :created_at)

ThinkingSphinx::SphinxError (index place_core: sort-by attribute 'created_at' not found):

I'm trying to accomplish a simple sort using parameters passed to my controller. I'm following the documentation on the Searching & Thinking Sphinx website and I'm met with the following error. What am I doing wrong?

The following @places object is an instance of the think Sphinx class.

 @places = Place.search(params[:q], :order => :created_at)

ThinkingSphinx::SphinxError (index place_core: sort-by attribute 'created_at' not found):

您需要添加要搜索的字段。然后，要按字段排序，您需要在模型中将其标记为可排序，或者需要在 define_index 方法中添加一个属性，如此处解释。

对于您的模型，如下所示：

class Place < ActiveRecord::Base
  # ...

  define_index do
    # fields
    indexes subject, :sortable => true
    indexes content
    indexes author.name, :as => :author, :sortable => true

    # attributes
    has created_at
  end

  # ...
end

在该示例中，主题、作者和created_at 是可排序的。

You need to add fields on which you want to search. Then to sort by a field you need to mark it as sortable in your model, or you need to add an attribute in the define_index method as explained here.

For your model, something like this:

class Place < ActiveRecord::Base
  # ...

  define_index do
    # fields
    indexes subject, :sortable => true
    indexes content
    indexes author.name, :as => :author, :sortable => true

    # attributes
    has created_at
  end

  # ...
end

In that example, subject, author and created_at are sortable.
