Question

我正在尝试将对代码进行的重大更改部署到heroku中。

当我运行heroku运行rails db：migrate时出现以下错误：

I, [2018-05-01T18:07:40.587276 #4]  INFO -- : Migrating to AddShopToListing (20180415173504)

PG::UndefinedTable: ERROR:  relation "shop" does not exist
: ALTER TABLE "listings" ADD CONSTRAINT "fk_rails_72ed4e1344"
FOREIGN KEY ("shop_id")
  REFERENCES "shop" ("id")

以下是违规的迁移文件：

class AddShopToListing < ActiveRecord::Migration[5.1]
  def change
    add_reference :listings, :shop, references: :shops, index: true
    add_foreign_key :listings, :shop, column: :shop_id
  end
end

我找不到导致此问题的原因 - 我唯一看到的是在我的heroku架构中我有以下几行：

  add_foreign_key "sellers", "users"
  add_foreign_key "shops", "listings"
  add_foreign_key "shops", "sellers"
  add_foreign_key "shops", "users"

当我在本地架构上时，我没有。

你能帮帮我吗？我尝试了所有方法，包括在我创建Shop模型的前一天在应用程序中回滚，但显然它没有推出数据库。

我还尝试在本地克隆它以处理代码，但它克隆了最近的提交，而不是当前在应用程序中活动的提交。

提前致谢！

问题出现在这里：

-- add_foreign_key(:listings, :shop, {:column=>:shop_id})
ALTER TABLE "listings" 
  ADD CONSTRAINT "fk_rails_72ed4e1344"
  FOREIGN KEY ("shop_id")
  REFERENCES "shop" ("id") -- <<<< HERE, it should be `shops` instead of `shop`

add_foreign_key的第二个参数应该是表的名称，在你的情况下：

add_foreign_key :listings, :shops, column: :shop_id
#                               ^ plural
