请帮助解决问题。
我创建了一个网站。我用的是sqlite3。 database.yml的:
default: &default
adapter: sqlite3
pool: 5
timeout: 5000
development:
<<: *default
database: db/development.sqlite3
test:
<<: *default
database: db/test.sqlite3
production:
<<: *default
database: db/production.sqlite3
的Gemfile:
source 'https://rubygems.org'
gem 'rails', '4.2.1'
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc
gem 'bootstrap-sass', '3.2.0.0'
gem 'bcrypt', '~> 3.1.7'
gem 'populate'
gem 'faker'
gem 'russian', '~> 0.6.0'
gem 'will_paginate'
gem 'paperclip'
gem 'fancybox2-rails', '~> 0.2.8'
gem 'rspec-rails'
gem 'factory_girl'
gem 'database_cleaner'
group :development do
gem 'sqlite3'
end
group :production do
gem 'pg'
gem 'rails_12factor'
end
group :development, :test do
gem 'byebug'
gem 'web-console', '~> 2.0'
gem 'spring'
end
在正在运行的本地服务器上。我把它上传到了heroku。收到以下错误消息的结果:
500内部服务器错误
heroku使用postgresql。那就是问题所在。请帮忙设置配置
答案 0 :(得分:0)
正如它所说:你需要添加pg
gem。在Gemfile中包含以下行
gem 'pg', group: :production
您在 config / database.yml 文件中,可以编写以下代码并进行适当的修改:
development:
adapter: postgresql
encoding: unicode
database: myapp_development
pool: 5
username: myapp
password: password1
test:
adapter: postgresql
encoding: unicode
database: myapp_test
pool: 5
username: myapp
password: password1
production:
adapter: postgresql
encoding: unicode
database: myapp_prouduction
pool: 5
username: myapp
password: password1
