**当我做" heroku db:push sqlite://mydatabase.db"我有Ruby + Sinatra + Sqlite3 + Heroku的问题:
当我这样做时:" heroku db:push sqlite://anotador.db"
控制台日志:
2013-01-21T12:37:11+00:00 app[web.1]: Errno::ENOENT - No such file or directory - /app/views/home.erb:
2013-01-21T12:37:11+00:00 app[web.1]: /app/vendor/bundle/ruby/1.9.1/gems/sinatra-1.3.3/lib/sinatra/base.rb:572:in `erb'
我的anotador.rb:
require 'rubygems'
require 'sinatra'
require 'data_mapper'
DataMapper::setup(:default, ENV['DATABASE_URL'] || "sqlite3://#{Dir.pwd}/anotador.db")
class Nota
include DataMapper::Resource
property :id, Serial
property :content, Text, :required => true
property :complete, Boolean, :required => true, :default => false
property :created_at, DateTime
property :updated_at, DateTime
end
DataMapper.finalize.auto_upgrade!
我的GemFile:
source :rubygems
gem 'sinatra'
gem 'data_mapper'
gem 'rack-flash'
gem 'sinatra-redirect-with-flash'
gem 'builder'
gem 'dm-postgres-adapter', :group => :production
gem 'dm-sqlite-adapter', :group => :development
gem 'thin'
group :development, :test do
gem 'sqlite3'
end
group :production do
gem 'pg'
end
在命令行中:
$ bundle
$ git init
$ git add .
$ git commit -m "comentario"
$ heroku create nombreAPP --stack cedar
$ git push heroku master
$ heroku addons:add heroku-postgresql:dev
$ heroku pg:promote <DATABASE_URL>
$ heroku db:push sqlite://anotador.db
我知道Heroku使用的是Postgres和SQLite
但是Heroku能够移动数据库并使用SQLite到Postgres这个链接中举例说明:
https://devcenter.heroku.com/articles/ruby #using-a-sql-database
我在开发和生产中使用sqlite3使用Postgres
在GemFile中:
group :development, :test do
gem 'sqlite3'
end
group :production do
gem 'pg'
end

答案 0 :(得分:1)
据我所知,你不能在Heroku上使用SQLite3。您可以使用Postgres或Mysql数据库。
所以当你说
时heroku db:push sqlite://mydatabase.db
你不应该这样做。它不起作用,因为Herite上没有SQLite Gem。什么是db:push
?这是一些佣金任务吗?我想你仍然需要将它指定给Heroku。
