ActiveRecord :: StatementInvalid（SQLite3 :: ReadOnlyException：當使用postgres

我想在Ubuntu的數字海洋部署我的第一個rails應用程序，我不確定我是否做這個權利。測試和生產sqllite。在挫折中，我改變了所有我的數據庫postgres我更改database.yml。我不確定如果我做到了這一點正確但我有這個錯誤：ActiveRecord :: StatementInvalid（SQLite3 :: ReadOnlyException：是sqllite。我不知道是否必須告訴服務器切換到生產模式，或者如果它被配置爲使用sqllite。ActiveRecord :: StatementInvalid（SQLite3 :: ReadOnlyException：當使用postgres

我想要做的是使用postgres而不是sqllite。我使用nginx和我的數據庫是空白的，所以我不需要傳輸任何東西。我做了postgres da在postgres中，我只需要將我的應用程序指向該數據庫即可。（我不知道如果我需要做些別的事情

我已經使用這個database.yml的

development: 
    adapter: postgresql 
    encoding: unicode 
    host: localhost 
    database: blog_development 
    pool: 5 
    username: bob 
    password: password 

test: 
    adapter: postgresql 
    encoding: unicode 
    database: blog_test 
    host: localhost 
    pool: 5 
    username: bob 
    password: password 

production: 
    adapter: postgresql 
    encoding: unicode 
    host: localhost 
    database: blog_production 
    pool: 5 
    username: bob 
    password: password

在什麼情況下你會得到那個錯誤？當你嘗試啓動控制檯？運行服務器？ – Bryce

當我嘗試寫入應用程序（發表評論）時發生這種情況：http://104.236.51.180/blogs/10 – applejuiceteaching

您可以運行'rake db：drop db：create db：migrate'嗎？你能登錄到Rails控制檯並通過該接口創建一個Comment對象嗎？如果不是，那麼錯誤是什麼？ – Bryce

運行rake db:drop db:create db:drop放棄舊數據庫（一個或多個），然後重新創建新的Postgres裏。
