Question

我在尝试登录生产URL的admin / login部分后运行heroku logs时出现以下错误：

ActiveRecord::StatementInvalid (PG::UndefinedTable: ERROR:  relation “admin_users"  does not exist

我已经尝试过这个帖子：https://github.com/gregbell/active_admin/issues/753，特别是以下建议步骤（建议在“新安装”上执行，我不清楚这意味着什么！）

rails g active_admin：devise
rails g active_admin：install
（如果由于＃2414导致安装失败，请从路径文件中删除重复的ActiveAdmin.routes（self），然后运行rails g active_admin：assets）删除add_devise_to_admin_users迁移文件
rake db：migrate

我已经完成了上述步骤，没有遵守“新安装”部分，但仍然遇到同样的错误。

以下是我的database.yml文件的副本：

# SQLite version 3.x
#   gem install sqlite3
#
#   Ensure the SQLite 3 gem is defined in your Gemfile  
#   gem 'sqlite3'
development:
  adapter: postgresql
  database: myapp_development
  pool: 5
  timeout: 5000
  password:

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: postgresql
  encoding: unicode
  database: myapp_test
  pool: 5
  timeout: 5000
  password:

production:
  adapter: postgresql
  database: myapp_production
  username: 
  password: 
  pool: 5
  timeout: 5000

这是我的Gemfile的副本

source 'https://rubygems.org'
ruby "2.1.1"

gem 'rails', '4.0.4'



gem 'sass-rails', '~> 4.0.2'


gem 'uglifier', '>= 1.3.0'

gem 'coffee-rails', '~> 4.0.0'

gem 'jquery-rails'


gem 'turbolinks'

# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 1.2'

group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc', require: false
end


gem 'activeadmin', github: 'gregbell/active_admin'

group :production do
  gem 'pg'
  gem 'rails_12factor'
end

通过git将代码推送到Heroku后，切换到项目根目录并运行：

$ heroku run rake db:migrate

这将在您的生产服务器上运行rake db:migrate。

PG：错误：关系“admin_users”不存在
