PG :: ConnectionBad FATAL：角色“Myname”不存在 [英] PG::ConnectionBad FATAL: role "Myname" does not exist

问题描述

我正在尝试使用PostgreSQL，以便我可以部署到Heroku。但是我不能再运行localhost为什么？我收到以下消息：

I am trying to use PostgreSQL so that I can deploy to Heroku. However I cannot run localhost anymore why? I get the following message:

PG::ConnectionBad
FATAL: role "Myname" does not exist

这是我的databse.yml

Here is my databse.yml

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 

这是我的gemfile：

似乎pg需要我创建用户或数据库，但是我无法或不愿意不知道如何。无法找到任何适用于我的命令（我在Windows btw上）

It seems that pg needs me to create a user or databse however I am unable to or don't know how. Couldn't find any commands that worked for me(I'm on a windows btw)

我能做什么？

推荐答案

我必须进入我的PG管理仪表板并在那里创建一个数据库/用户。不幸的是，它位于与在线教程不同的子目录中（可能更新了目录目的地的最新更新）。幸运的是，我能够找到它并在那里创建表格/用户，更新我的database.yml文件，然后我的应用程序就可以工作了！

I had to go into my PG admin dashboard and create a db/user there. Unfrotunately it was in a subdirectory different from what the tutorials online said(probably updated directory destination last update). Fortunately I was able to find it and create the table/user there, update my database.yml file and then my app was able to work!
