Question

I’m using rack mini profiler in rails just fine, but during some coding sessions especially where I’m working on a lot of different client side code, it gets in the way. (mainly in my client side debugging tools network graphs, etc.)

I’m trying to turn it off with a before filter, that also serves to see if the user is authorized to see the profile anyway, but “deauthorize” doesn’t seem to do anything for me. Here’s my code called as a before filter:

def miniprofiler  
 off = true
 if off || !current_user
  Rack::MiniProfiler.deauthorize_request
  return
 elsif current_user.role_symbols.include?(:view_page_profiles)    
  Rack::MiniProfiler.authorize_request
  return
 end
 Rack::MiniProfiler.deauthorize_request
end

I also know there is a setting “Rack::MiniProfiler.config.authorization_mode” but I can’t find docs on what the possible settings are, and not seeing it used in the code? Right now its telling me :allow_all, but :allow_none doesn’t do anything either.

Even if I can just temporarily set a value in the dev environment file and restart the server, that would serve my purposes.

Get latest and type:

http://mysite.com?pp=disable

When you are done type

http://mysite.com?pp=enable

See ?pp=help for all the options:

Append the following to your query string:

  pp=help : display this screen
  pp=env : display the rack environment
  pp=skip : skip mini profiler for this request
  pp=no-backtrace : don't collect stack traces from all the SQL executed (sticky, use pp=normal-backtrace to enable)
  pp=normal-backtrace (*) : collect stack traces from all the SQL executed and filter normally
  pp=full-backtrace : enable full backtraces for SQL executed (use pp=normal-backtrace to disable) 
  pp=sample : sample stack traces and return a report isolating heavy usage (experimental works best with the stacktrace gem)
  pp=disable : disable profiling for this session 
  pp=enable : enable profiling for this session (if previously disabled)
  pp=profile-gc: perform gc profiling on this request, analyzes ObjectSpace generated by request (ruby 1.9.3 only)
  pp=profile-gc-time: perform built-in gc profiling on this request (ruby 1.9.3 only)
