Question

新手在这里。我正在尝试将我的应用程序推送到heroku，下载postgres并从我的gemfile中删除了gem'sqlite3'。我需要更新我的database.yml，并且不知道在“ my_database_development”前面放什么？这是我的问题。我如何设置

这是我的代码

default: &default
  adapter: postgresql
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
  timeout: 5000

development:
  <<: *default
  database: db/development.sqlite3

# 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:
  <<: *default
  database: db/test.sqlite3

production:
  <<: *default

  database: db/production.sqlite3

我正在努力实现以下目标

development:
  adapter: postgresql
  database: my_database_development
  pool: 5
  timeout: 5000
test:
  adapter: postgresql
  database: my_database_test
  pool: 5
  timeout: 5000

production:
  adapter: postgresql
  database: my_database_production
  pool: 5
  timeout: 5000

Answer 1

您所拥有的代码仍在引用sqlite

  database: db/production.sqlite3

使用您拥有的另一个块。另外，在您的sqlite中可能引用了Gemfile.lock，但是我认为部署时它会被覆盖。

这是到database.yml文件示例的链接，使您的文件看起来像Postgres的文件。

Answer 2

在将postgres添加到gemfile中时，就会发生这种情况，但是您要么：

未从gemfile中删除sqlite3
添加postgres并删除sqlite3后，您尚未运行bundle install

我正在尝试将我的应用程序推送到heroku，但是没有通过
