如何根据字段的权重对字段（在模板中）进行排序？

Question

我使用thinking_sphinx进行搜索，并且我正在尝试获取输出表，其中字段根据权重进行分组（来自set_property：field_weights）

此define_block

  define_index do
    indexes status, title, content, manager, note, start_date, end_date
    has created_at, updated_at, parent_id, organization_id

    has user_id, :as => :user_id, :type => :integer

    has '7', :as => :model_order, :type => :integer

    set_property :field_weights => {
      :title => 1,
      :start_date => 2,
      :user_id => 7
    }

    set_property :delta => true
  end

我不确定我是否理解问题，但似乎您正在尝试从视图中读取 field_weights 的配置...
我不知道 Thinking_sphinx 是否有方法可以做到这一点，但我要做的就是保存该配置并在需要的地方使用它...

class YourModel
    FieldWeights = {
        :title => 1,
        :start_date => 2,
        :user_id => 7
    }
  # more code here....

  define_index do
    indexes status, title, content, manager, note, start_date, end_date
    has created_at, updated_at, parent_id, organization_id

    has user_id, :as => :user_id, :type => :integer

    has '7', :as => :model_order, :type => :integer

    set_property :field_weights => YourModel::FieldWeights

    set_property :delta => true
  end
end

然后在您看来，您可以使用 YourModel::FieldWeights 显示中的字段它们的权重顺序，例如：

YourModel::FieldWeight.invert.sort
