问题描述

我正在使用RailsAdmin,这是我在RailsAdmin中单击我的模型 CategoryProduct 时遇到的错误。

这些是我的类别产品& category_product models:



Category.rb

 #==架构信息

#表名称:类别

# id:integer不为null,主键
#name:string(255)
#created_at:datetime不为空
#updated_at:datetime不为空


class Category< ActiveRecord :: Base
attr_accessible:name
has_many:category_products do
def with_products
包含(:product)
end
end

has_many:products,:through => :category_products

def top_products(number)
category_products.with_products.order(purchases_count DESC)。limit(number).map {| c | c.product}#含产品
结束

结束

Product.rb

 #==模式信息

#表名:产品

#id:integer不为null,主键
#name:string(255)
#description:string(255)
#price:float

#updated_at:datetime not null
#image:string(255)


class产品< ActiveRecord :: Base
attr_accessible:name,:description,:price,:vendor_id,:image,:category_ids
mount_uploader:image,ImageUploader

elongs_to:vendor
has_many:category_products do
def with_categories
包含(:category)
end
end
$ b has_many:categories,:through => :category_products

def top_categories(number)
category_products.with_categories.order(purchases_count DESC)。limit(number).map {| c | c.category}#包含的类别
结束

结束

Category_Product

 #==模式信息

#表名:category_products

#id:整数不为空,主键
#product_id:整数
#category_id:整数
#purchases_count:整数缺省值(0)
#created_at:datetime not null
#updated_at:datetime not null


class CategoryProduct< ActiveRecord :: Base
attr_accessible:product_id,:category_id,:purchases_count
$ b belongs_to:产品
belongs_to:类别

validates_uniqueness_of:product_id,:scope = > :category_id
end

有什么想法可能导致这种情况?



谢谢。

解决方案

原来问题出在Heroku身上(我认为) / p>

我对代码库进行了另一次更新,这个问题似乎消失了。


I am using RailsAdmin and this is the error I get when I click on my model CategoryProduct within RailsAdmin.

This is what the error looks like:

These are my category, product & category_product models:

Category.rb

       end

  has_many :products, :through => :category_products

  def top_products(number)
    category_products.with_products.order("purchases_count DESC").limit(number).map {|c| c.product} # product included
  end

end

    has_many :category_products do

             includes(:category)
           end
    end

    has_many :categories, :through => :category_products

  def top_categories(number)
    category_products.with_categories.order("purchases_count DESC").limit(number).map {|c| c.category} # category included
  end

end

Category_Product

#

class CategoryProduct < ActiveRecord::Base
  attr_accessible :product_id, :category_id, :purchases_count

    belongs_to :product
  belongs_to :category

  validates_uniqueness_of :product_id, :scope => :category_id
end

Any ideas what may be causing this?

Thanks.

解决方案

Turns out the problem was on Heroku's side (I assume).

I did another push with a different update to the codebase and this problem seemed to go away.
