Heroku – ActionView :: Template :: Error（PG ::错误：错误：列category_products.desc不存在
我正在使用RailsAdmin，这是我在RailsAdmin中单击我的模型CategoryProduct时出现的错误。
这就是错误的样子：
Started GET "/admin/category_product" for 67.230.41.62 at 2012-12-21 23:20:07 +0000 2012-12-21T23:20:07+00:00 app[web.1]: 2012-12-21T23:20:07+00:00 app[web.1]: ActionView::Template::Error (PG::Error: ERROR: column category_products.desc does not exist 2012-12-21T23:20:07+00:00 app[web.1]: LINE 1: ...ry_products".* FROM "category_products" ORDER BY category_p... 2012-12-21T23:20:07+00:00 app[web.1]: ^ 2012-12-21T23:20:07+00:00 app[web.1]: : SELECT "category_products".* FROM "category_products" ORDER BY category_products. desc LIMIT 20 OFFSET 0): 2012-12-21T23:20:07+00:00 app[web.1]: 120: %tbody 2012-12-21T23:20:07+00:00 app[web.1]: 121: - @objects.each do |object| 2012-12-21T23:20:07+00:00 app[web.1]: 122: %tr 2012-12-21T23:20:07+00:00 app[web.1]: 123: %td 2012-12-21T23:20:07+00:00 app[web.1]: 124: = check_box_tag "bulk_ids[]", object.id, false 2012-12-21T23:20:07+00:00 app[web.1]: 125: - if @other_left_link ||= other_left && index_path(params.except('set').merge(params[:set].to_i != 1 ? {:set => (params[:set].to_i - 1)} : {})) 2012-12-21T23:20:07+00:00 app[web.1]: 126: %td.other.left= link_to "...", @other_left_link, :class => 'pjax'^
这些是我的category ， product和category_product型号：
Category.rb
# == Schema Information # # Table name: categories # # id :integer not null, primary key # name :string(255) # created_at :datetime not null # updated_at :datetime not null # class Category :category_products def top_products(number) category_products.with_products.order("purchases_count DESC").limit(number).map {|c| c.product} # product included end end
Product.rb
# == Schema Information # # Table name: products # # id :integer not null, primary key # name :string(255) # description :string(255) # price :float # vendor_id :integer # created_at :datetime not null # updated_at :datetime not null # image :string(255) # class Product :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
# == Schema Information # # Table name: category_products # # id :integer not null, primary key # product_id :integer # category_id :integer # purchases_count :integer default(0) # created_at :datetime not null # updated_at :datetime not null # class CategoryProduct :category_id end
可能导致这种情况的任何想法？
谢谢。
事实certificate问题出在Heroku的一边（我猜）。
我用代码库的不同更新做了另一次推送，这个问题似乎消失了。
