耙资产:预编译RAILS_ENV =生产错误 [英] rake assets:precompile RAILS_ENV=production Error

问题描述

我想将一个狂欢应用程序部署到heroku，为此，我需要在本地预编译资产 我做了

I want to deploy a spree app to heroku and in order to do that I need to precompile my assets locally I did

heroku addons:create heroku-postgresql 

然后我添加了config/application.rb

then I added config/application.rb

config.assets.initialize_on_precompile = false

我的database.yaml文件是

my database.yaml file is

default: &default
  adapter: postgresql
  encoding: unicode
  pool: 5

development:
  <<: *default
  host: localhost
  database: anzels_development
  username: anzels
  password: 1234

test:
  <<: *default
  host: localhost
  database: anzels_test
  username: anzels
  password: 1234


production:
  adapter: postgresql
  encoding: unicode
  database: anzels_production
  pool: 5
  password:

以及我每次跑步

sumeet@sumi-pc:~/anzels$ rake assets:precompile RAILS_ENV=production

我收到一个错误 耙子中止了！

I get an error rake aborted!

ActiveRecord::NoDatabaseError: FATAL:  role "sumeet" does not exist
/home/sumeet/anzels/config/environment.rb:5:in `<top (required)>'
PG::ConnectionBad: FATAL:  role "sumeet" does not exist
/home/sumeet/anzels/config/environment.rb:5:in `<top (required)>'
Tasks: TOP => environment
(See full trace by running task with --trace)

config/enviormenr.rb

# Load the Rails application.
require File.expand_path('../application', __FILE__)

# Initialize the Rails application.
Rails.application.initialize!

请帮助

推荐答案

在本地计算机上，您尝试运行

In local computer you are trying to run

rake资产:预编译RAILS_ENV =生产

rake assets:precompile RAILS_ENV=production

但这需要您的本地计算机具有config/database.yml，并带有@ thieu-nguyen提到的配置

but this requires your local compute to have config/database.yml with the config mentioned by @thieu-nguyen

因此请在以下内容中添加

so add the following in

用户名:$ PRODUCTION_DB_USER

username: $PRODUCTION_DB_USER

密码:$ PRODUCTION_DB_PASS

password: $PRODUCTION_DB_PASS

正在生产中 config/database.yml

然后为您的本地计算机添加环境

then add the environment for you local computer as

PRODUCTION_DB_USER = anzels

PRODUCTION_DB_USER=anzels

PRODUCTION_DB_PASS = 1234

PRODUCTION_DB_PASS=1234

，对于heroku，

PRODUCTION_DB_USER =用户

PRODUCTION_DB_USER=user

PRODUCTION_DB_PASS ="" (空)

PRODUCTION_DB_PASS="" (empty)

另一种简便方法

ANOTHER EASIER WAY IS

用户名:anzels

username: anzels

密码:1234

config/database.yml 中的生产 **仅在进行预编译之前** 然后运行命令

to production in config/database.yml **JUST BEFORE assests precompilation ** then run command

git checkout config/database.yml

git checkout config/database.yml

在执行GIT COMMIT命令之前 想法是不要提交用户名和密码，而是临时编辑它，以仅用于预编译目的

JUST BEFORE GIT COMMIT command the idea is to not to commit the username and password but temporarily edit it for assests precompilation purpose only
