Heroku上的Rails 4.0.1不能创建数据库 [英] Rails 4.0.1 on Heroku, can't create database

问题描述

我猜我没有使用postgres配置正确...但阅读关于heroku的文档并没有真正帮助，我不知道该怎么做。我不太了解heroku或postgres。

任何帮助或资源将不胜感激。

（另外，我使用的是设计，如果有的话）

当我运行 heroku运行rake db：migrate 我得到这个：

 运行`rake db：migrate`附加到终端... up，run.5077 
 PG :: UndefinedTable：ERROR：关系users不存在
 LINE 5：WHERE a。 attrelid ='users'：regclass 
 ^ 
：SELECT a.attname，format_type（a.atttypid，a.atttypmod），
 pg_get_expr（d.adbin，d.adrelid） ，a.attnotnull，a.atttypid，a.atttypmod 
 FROM pg_attribute a LEFT JOIN pg_attrdef d 
 ON a.attrelid = d.adrelid AND a.attnum = d.adnum 
 WHERE a。 attrelid ='users':: regclass 
 AND a.attnum> 0 AND NOT a.attisdropped 
 ORDER BY a.attnum 
 
 rake aborted！ 
 PG :: UndefinedTable：ERROR：关系users不存在
 LINE 5：WHERE a.attrelid ='users''：regclass 
 ^ 
：SELECT a .attname，format_type（a.atttypid，a.atttypmod），
 pg_get_expr（d.adbin，d.adrelid），a.attnotnull，a.atttypid，a.atttypmod 
 FROM pg_attribute a LEFT JOIN pg_attrdef d 
 ON a.attrelid = d.adrelid AND a.attnum = d.adnum 
 WHERE a.attrelid ='users''：regclass 
 AND a.attnum> 0 AND NOT a.attisdropped 
 ORDER BY a.attnum 
  

当我运行 heroku run rake db：setup 我得到这个：

  FATAL：数据库的权限被拒绝postgres
详细信息：用户没有CONNECT权限。 
 
 ...堆栈跟踪... 
 
无法为{adapter=>postgresql，username=>aqofwrwjifcqkx创建数据库，password=>7yqDAx1L_4HFhw7WV3PH7ZrKyM，port=> 5432，database=>d5dvi0pjk7dgr7，host=>ec2-23-21-94-137.compute-1。 amazonaws.com} 
  

后跟相同的PG :: UndefinedTable错误关系'users'不存在

解决方案 div>

我应该更仔细地阅读堆栈跟踪。我的factories.rb创建用户对象作为其他工厂的属性。将它们包装在一个块中修复它：

FactoryGirl拧up rake db：迁移进程

I can't get rake db:migrate to run on my rails 4.0.1 app on Heroku.

I'm guessing that I don't have postgres configured properly... but reading the docs on heroku hasn't really helped and I'm not sure what to do. I don't know too much about heroku or postgres.

Any help or resources would be greatly appreciated. Let me know if there's anything else I can post.

(Also, I'm using devise, if that matters)

When I run heroku run rake db:migrate I get this:

Running `rake db:migrate` attached to terminal... up, run.5077
PG::UndefinedTable: ERROR:  relation "users" does not exist
LINE 5:                WHERE a.attrelid = '"users"'::regclass
                                      ^
:               SELECT a.attname, format_type(a.atttypid, a.atttypmod),
                 pg_get_expr(d.adbin, d.adrelid), a.attnotnull, a.atttypid, a.atttypmod
            FROM pg_attribute a LEFT JOIN pg_attrdef d
              ON a.attrelid = d.adrelid AND a.attnum = d.adnum
           WHERE a.attrelid = '"users"'::regclass
             AND a.attnum > 0 AND NOT a.attisdropped
           ORDER BY a.attnum

rake aborted!

                                      ^
:               SELECT a.attname, format_type(a.atttypid, a.atttypmod),
                 pg_get_expr(d.adbin, d.adrelid), a.attnotnull, a.atttypid, a.atttypmod
            FROM pg_attribute a LEFT JOIN pg_attrdef d
              ON a.attrelid = d.adrelid AND a.attnum = d.adnum
           WHERE a.attrelid = '"users"'::regclass
             AND a.attnum > 0 AND NOT a.attisdropped
           ORDER BY a.attnum

When I run heroku run rake db:setup I get this:

FATAL:  permission denied for database "postgres"
DETAIL:  User does not have CONNECT privilege.

... stack trace ...

Couldn't create database for {"adapter"=>"postgresql", "username"=>"aqofwrwjifcqkx", "password"=>"7yqDAx1L_4HFhw7WV3PH7ZrKyM", "port"=>5432, "database"=>"d5dvi0pjk7dgr7", "host"=>"ec2-23-21-94-137.compute-1.amazonaws.com"}

followed by the same PG::UndefinedTable ERROR relation 'users' does not exist

database.yml :

development:
  adapter: sqlite3
  encoding: unicode
  database: chore_app_development
  pool: 5

test:
  adapter: sqlite3
  encoding: unicode
  database: chore_app_test
  pool: 5

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

Gemfile:

source 'https://rubygems.org'
ruby '2.0.0'

gem 'rails', '4.0.1'

# Database
group :production do
  gem 'pg'
end

group :development, :test do
  gem 'sqlite3'
end

# Assets
gem 'sass-rails', '~> 4.0.0'
gem 'uglifier', '>= 1.3.0'

# Heroku
gem 'rails_12factor', group: :production

# Application

# Testing

解决方案

I should've read the stack trace more closely. My factories.rb was creating user objects as attributes for other factories. Wrapping them in a block fixed it:

FactoryGirl screws up rake db:migrate process
