如何以这种方式对太阳黑子进行分页？
我有以下模型关联：
class Product < ActiveRecord::Base
has_many :prices
class Price < ActiveRecord::Base
belongs_to :product
这是我的控制器
class SearchController < ApplicationController
# Using Sunspot here.
def index
@search = Product.search do
fulltext params[:search]
paginate(:per_page => 5, :page => params[:page])
end
@products = @search.results
end
end
，然后是我的视图：
<%= will_paginate @products %>
<% @products.each do |product| %>
<%= product.name %>
<% prices.each do |price| %>
<%= price.price %>
<% end %>
<% end %>
假设我有 10 个产品，每个产品有 20 个不同的价格。我的目标是每页显示 5 个产品，但如果页面上的价格数量一次超过 25 个，则价格会转到下一页。
这是我想要它做什么的两个不同的例子：
Product 1, 2, 3, 4 + 5 Prices each = same page
Product 5 + 6 Prices = this Product with Prices on next page
或者
Product 1 + 23 prices = same page
Product 2 + 20 prices = next page with Product and prices
我怎样才能实现这个？
I have the following model associations:
class Product < ActiveRecord::Base
has_many :prices
class Price < ActiveRecord::Base
belongs_to :product
Here is my controller
class SearchController < ApplicationController
# Using Sunspot here.
def index
@search = Product.search do
fulltext params[:search]
paginate(:per_page => 5, :page => params[:page])
end
@products = @search.results
end
end
and then my view:
<%= will_paginate @products %>
<% @products.each do |product| %>
<%= product.name %>
<% prices.each do |price| %>
<%= price.price %>
<% end %>
<% end %>
Lets say I have 10 Products that each have 20 different Prices. My goal is to show 5 Products per page but have the Prices run over to the next page if the amount of Prices on a page exceeds a maximum of 25 at a time.
Here is two different examples of what I want it to do:
Product 1, 2, 3, 4 + 5 Prices each = same page
Product 5 + 6 Prices = this Product with Prices on next page
Or
Product 1 + 23 prices = same page
Product 2 + 20 prices = next page with Product and prices
How can I achieve this?

我想到的第一件事是查询价格模型：
并且为了让您的视图更容易：
prices.map！ { |p| p.产品}The first thing that comes to my mind is to query over the Price model:
And to make things easier for your views:
prices.map! { |p| p.product }
