config.filter_parameters doesn't affect debug(params)
Reported by greg (at araelium) | September 18th, 2010 @ 07:06 AM
Seems to me that <%= debug(params) %> should be modified by config.filter_parameters
It's not unprecedented -- I used a language (Lasso) for many years which this similar ability of config.filter_parameters, and whenever the equivalent of params was displayed, that list was filtered to prevent display of identified values, though it still displayed the names of course.

I don't think so imho. Debug is for debugging and you don't want to filter any parameters at that time. You shouldn't be developing with the production database any way so you shouldn't be looking at any important params. It's main job is to filter sensitive params from the logs.
Anybody else have an opinion on this?

Mmm, I can see where that logic might arise, and I'll attempt a counter thought with "if it's sensitive, it's sensitive" and the framework shouldn't be making any assumptions as to when it is or isn't suitable to be displayed. config.filter_parameters allows me to decide that I don't want certain things to show accidently outside my app code, so the framework should make that as universally applicable as possible. I can use other methods to override that if I need to from removing it, to using environments (I think), to something as barbaric as re-assigning to another var name to output if I really need to see it.
Anyway, I guess that's my 4¢. Just something to consider.

I totally agree with Rohit.
There will always be a way to somehow disclose filtered params in development. A silly example:
class SessionsController < ApplicationController def create raise params[:password] # oh no, security breach! end end
You chose to display what's in params while in the development environment - that's your responsibility. Besides, as Rohit said, of course you're not working with sensitive data in development.
IMHO, this should just be marked
wontfix
