Ruby on rails 为什么可以'；从SQLite迁移后，我的应用程序是否会修改开发postgresql数据库？,ruby-on-rails,windows,sqlite,migration,rails-postgresql,Ruby On Rails,Windows,Sqlite,Migration,Rails Postgresql,我将开发数据库从SQLite切换到postgresql。我的应用程序在开发和生产（Heroku，postgresql）中都能工作，但现在我无法在新的postgresql开发数据库中修改、删除或创建记录。用户只能正确登录、查看其个人资料信息和注销创建用户时出错： ActiveRecord::StatementInvalid in Devise::RegistrationsController#create Errno::EBADF: Bad file descriptor - rb_threa

我将开发数据库从SQLite切换到postgresql。我的应用程序在开发和生产（Heroku，postgresql）中都能工作，但现在我无法在新的postgresql开发数据库中修改、删除或创建记录。用户只能正确登录、查看其个人资料信息和注销

创建用户时出错：

ActiveRecord::StatementInvalid in Devise::RegistrationsController#create

Errno::EBADF: Bad file descriptor - rb_thread_select(): INSERT INTO "users" ("field1", "field2", "field3", ...etc continues through..., "Field28") VALUES ($1, $2, $3, $4, $5, $6, $7, $8, $9, $10, $11, $12, $13, $14, $15, $16, $17, $18, $19, $20, $21, $22, $23, $24, $25, $26, $27, $28) RETURNING "id"

删除用户时出错：

ActiveRecord::StatementInvalid in Devise::RegistrationsController#destroy

Errno::EBADF: Bad file descriptor - rb_thread_select(): DELETE FROM "users" WHERE "users"."id" = $1

这一切在生产中都是正确的

我在Windows 7上使用Cygwin，并使用pgAdmin Windows包安装postgresql

我使用以下方法创建了新数据库4次，所有这些方法都产生了上述相同的结果

在pgAdmin中创建了一个空数据库，并使用

rake db:migrate

正确创建了字段，但应用程序无法创建记录

在pgAdmin中创建了一个空数据库，然后使用与#1结果相同的

db:schema:load

在pgAdmin中创建了一个空数据库。使用

pgbackups

从我的生产应用程序创建一个

.dump

文件，然后使用

pgrestore

进入新的空数据库。所有字段和记录看起来都不错，但仍然无法修改、删除或创建。只能登录并查看用户配置文件

按照从4:40开始的描述，使用所有步骤，包括轻敲宝石。所有字段和记录看起来都很好，但行为与#3相同

我可以通过pgAdmin GUI或

psql mydatabase

命令行直接与数据库交互

database.yml

development:
  adapter: postgresql
  encoding: unicode
  database: devdatabase
  pool: 5
  username: postgres
  password: 'password'

test:
  adapter: postgresql
  encoding: unicode
  database: testdatabase
  pool: 5
  username: postgress
  password: 'password'

我的postgresql日志显示成功连接到数据库：

为什么我不能从新创建的开发数据库中获得全部功能，而在生产中一切都正常工作？我从研究中了解到，在开发和生产中拥有相同的数据库是很重要的

我是新手，正在学习ruby、rails、数据库和postgresql。stackoverflow非常有用

我可以通过pgAdmin GUI或psql>mydatabase命令行直接与数据库交互

那么，为什么还要继续摆弄数据库呢？这不是给你带来麻烦的部分

这：

EBADF:错误的文件描述符

表示连接有问题，甚至可能是数据库连接库本身有问题

在PostgreSQL中打开连接日志记录。在应用程序中打开日志记录。在进一步查看之前，请确保您可以连接
