太阳黑子可以在阵列内搜索吗? [英] Can sunspot search inside array?

问题描述

我有下一个带有数组字段的模型:

I have the next model with a array field:

Class Invitation
 include Mongoid::Document
 include Mongoid::Timestamps::Created
 include Sunspot::Mongo

 field :recipients, :type => Array
 attr_accessible :recipients

 searchable do
  text :recipients do
  recipients.map { |recipient| recipient }
  end
 end

end

我的控制器中有:

def recipients

 @invitation = Invitation.find(params[:id])
 @search = Invitation.search do |s|
 s.fulltext params[:search]
 s.with(:recipients, @invitation.recipients)
 end

@recipients = @search.results
  respond_to do |format|
   format.html
  end

end

这个当我重新索引时没有显示错误但是:

This when I reindex not show error but:

这对我来说不太好.我在日志中收到下一个错误:

This not works fine for me. I get the next error in log:

Sunspot::UnrecognizedFieldError(没有为名为收件人"的邀请配置字段):

Sunspot::UnrecognizedFieldError (No field configured for Invitation with name 'recipients'):

我也试过了:

string :recipients do
  recipients.map { |recipient| recipient }
end

但是当我重新索引时出现下一个错误:

But I get the next error when I reindex:

recipients is not a multiple-value field, so it cannot index values []

我能解决这个问题吗?

推荐答案

Invitation 模型与 recipients 有一个 has_many 关联.这意味着一个 invitation 可以有多个 recipients.

The Invitation model has a has_many association with recipients. This means an invitation can have multiple recipients.

所以，试试这个:

string :recipients, :multiple => true do
  recipients.map { |recipient| recipient }
end
