Ruby on rails ActiveRecord关系：在ActiveRecord:：Relation对象内追加对象

我有以下型号：

#models/location.rb
class Location < ActiveRecord::Base
    scope :partner_locations, ->{where(partner: true)}
    scope :education_locations, ->{where(education: true)}
end

#models/location.rb
类位置{where（合作伙伴：true）}
经营范围：教育地点，->{where（教育：true）}
结束

然后我有以下代码：

locations = Location.none
if true
  #append onto that locations activerecord::relation object those locations that are partner locations
  locations << Location.partner_locations
end
if true
  #append onto that locations activerecord::relation object those locations that are education locations
  locations << Location.education_locations
end
return locations

locations=Location.none
如果是真的
#将作为合作伙伴位置的位置附加到该位置activerecord:：relation对象
位置如果有人有更好的方法，我很想知道

我通过将它附加到一个常规数组来完成我想做的事情，然后在返回它之前，我将它转换成一个activerecord:：relation，这样我就可以对它使用activerecord方法。如果我能用同一个activerecord:：object完成整个过程，那就太好了：

locations = []
if true
  #append onto that locations array all the location objects that are partner locations
  locations = locations + Location.partner_locations
end
if true
  #append onto that locations array all those location objects those locations that are education locations
  locations = locations + Location.education_locations
end
return Location.where(id: locations.map(&:id)).order(:name)

请尝试以下操作：

@locations = Location.order(:name)
@locations = @locations.partner_locations if # what ever logic 
@locations = @locations. education_locations if # what ever logic 
@locations

您能否放置调试器或绑定并验证Location.partner\u locations和Location.education\u locations的输出内容？您还可以发布locations=Location.none的其余代码（如父方法），如果为true。。。。。似乎可以确保什么都不会被退回。您可以使用不同的基本作用域，并且只有在没有其他条件匹配的情况下才附加none。
