如何访问默认的Rails sqlite数据库? [英] How to access default Rails sqlite db?

问题描述

我想在使用Rails进行开发时查看我数据库中的数据(实际上这三个方面都是开发，测试和生产).我没有接触过配置，因此应该很容易，但是我找不到任何可用的信息.

I would like to view the data in my DB while developing with Rails (actually in all 3 of them development, test and production). I have not touched the configs, so it should be easy, but I was not able to find any usable info.

我不知道连接字符串可能是什么，或者在哪里输入连接字符串，因为Aptana(v.3)似乎缺少我从Eclipse知道的旧数据源资源管理器视图.有人可以指出我正确的方向吗?

I have no idea what the connection string could be or where to enter it, since Aptana (v.3) seems to lack the good old data source explorer view I know from Eclipse. Could someone point me into the right direction?

推荐答案

您忽略了所使用的操作系统.

You have neglected to mention the OS you are using.

一种方法是在终端中使用sqlite3命令.

One way is to use the sqlite3 command in your terminal.

sqlite3 db/development.sqlite3

但是，对于诸如检查行之类的事情，您最好使用Rails控制台.

However, for things like inspecting your rows, you would be better using a rails console.

rails c
> User.all # Where user is your model.

注意::请勿直接通过sqlite3更改数据库架构，如果您来自其他Web堆栈背景，可能会习惯这种做法.这是因为下次运行迁移时，状态将与Rails期望的状态不同.

NOTE: Do not change your DB schema directly through sqlite3, something you may be used to if you come from a different web stack background. This is because the next time you run the migrations, the state will be different to what rails expects.
