request.fullpath with no parameters

what about a simple split:

request.fullpath.split("?")[0]

Use path instead of fullpath.

Although not documented, request.path worked for me. I usually use my plugin rails_web_console for playing with the request object.

Update:

As noticed by turboladen, "[ActionDispatch::Request][2] inherits from [Rack::Request‌][3]​, where request.path is defined".

path is not documented there, but the source displays script_name + path_info.

regular expression

request.fullpath.gsub( /\?.*/, "" )

no need for splitting,

request.path_info

gives you just that
