如何通過與太陽黑子協會進行搜索？

Question

我有2種型號：

class UserPrice < ActiveRecord::Base 
    attr_accessible :price, :product_name 
    belongs_to :user 
    belongs_to :product 

    searchable do 
    integer :product_id do 
     product.map(&:name) 
    end 
    end 

    # Associations on form like "choosing a category". 
    def product_name 
    product.name if product 
    end 

    def product_name=(name) 
    self.product = Product.find_or_create_by_name(name) unless name.blank? 
    end 
end 

--------------------------------------------------------------------------------- 
class Product < ActiveRecord::Base 
    attr_accessible :name 
    has_many :user_prices 
    has_many :users, :through => :user_prices 
end 

我想我UserPrice模型內搜索，而是由產品名稱進行搜索。這個塊在內部是如何完成的？

Answer 1

class UserPrice < ActiveRecord::Base 
    belongs_to :product 

    searchable do 
    text :product_name do 
     product.name 
    end 
    end 
end
