Rails-启动服务器后没有命令提示符？

Question

total n00b question here but I can't seem to find the answer searching around here or the web.

I have Ruby v1.8.7 (2009-06-12 patchlevel 174) and Rails v.2.3.5 installed on my Mac (10.6.8). I have no problem generating a Rails directory and starting the Ruby server, but what happens is that once the server is started I have no prompt and no code I type seems to execute.

to be specific - here is the terminal code from a session:

bvb:new bennettvonbennett$ ruby script/server
=> Booting Mongrel
=> Rails 2.3.5 application starting on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

after this point there is no prompt and no command I type seems to produce a result.

what am I doing wrong?

Answer 1

This is the correct behavior. You're not doing anything wrong.

The server runs in the foreground so that you can see the log output on every page load without having to open a specific log file. It's very helpful for debugging and staying aware of what the code you write does to the application and the database.

To return to a normal command prompt, you can send an end-of-text character (usually ctrl-c) to stop the server. Most of us Rails-folk work with multiple terminal windows open - server running in one, and others for other functions, such as the rails console, started with

ruby script/console

which will let you experiment with other Rails controller functions, much like irb for standard Ruby.

Answer 2

With ruby script/server you launch the webserver. Run ruby script/console if you want to execute commands against your current Rails application.

Answer 3

You're loooking for:

script/console

If you want to play with your project in a console.
