从Rails控制台调用ActionController方法

Posted 2021-02-26

The 'request' and 'response' objects are chock full of useful info. But console can't usually access them. Here's how:
start the server with the -u option, insert a breakpoint where you would like to have access to the controllers/helpers/etc. When finished, just type 'cont' to continue execution

# terminal
script/server -u
 
# /some/view.erb
<% debugger %>
 
# open the url associated with that view, and switch over to the terminal to play with ActionController methods and objects
