我想让一个使用PostgreSQL的rails应用程序,但是发生了一些奇怪的事情。我的朋友能够安装PostgreSQL并执行:
sudo su
su postgres
createdb development
接着是
rails server
没有错误。但是,当我尝试这样做时,我得到一个奇怪的错误:
/Users/user/.rvm/gems/ruby-1.9.3-p194/gems/activerecord 3.2.5/lib/active_record/connection_adapters/postgresql_adapter.rb:1151:in `async_exec': PG::Error: ERROR: relation "reports" does not exist (ActiveRecord::StatementInvalid)
LINE 4: WHERE a.attrelid = '"reports"'::regclass
^
: SELECT a.attname, format_type(a.atttypid, a.atttypmod), d.adsrc, a.attnotnull
FROM pg_attribute a LEFT JOIN pg_attrdef d
ON a.attrelid = d.adrelid AND a.attnum = d.adnum
WHERE a.attrelid = '"reports"'::regclass
AND a.attnum > 0 AND NOT a.attisdropped
ORDER BY a.attnum
请注意,“reports”是应用程序中的模型。
对于它的价值,database.yml文件如下所示:
development:
adapter: postgresql
encoding: unicode
database: development
pool: 5
username: postgres
password: post
(我不知道哪个池意味着什么,但我已经设置了postgres密码才能发布)
答案 0 :(得分:2)
您运行rake db:migrate
吗?
答案 1 :(得分:0)
WHERE a.attrelid = '"reports"'::regclass ...
引用太多了。它应该是WHERE a.attrelid = 'reports'::regclass ...
