Rails monkey patch initializer

By default in production we attempt to set the authorization mode to :whitelist meaning that end user will only be able to see requests where somewhere Rack::MiniProfiler.

Various aspects of rack-mini-profiler's behavior can be configured when your app boots. This probably won't ever break your application, but it can cause some unexpected behavior.

For example, in a Rails app, calls to stale? MemoryStore is the default otherwise. MemoryStore stores results in a processes heap - something that does not work well in a multi process environment.

FileStore stores results in the file system - something that may not work well in a multi machine environment. MiniProfiler will attempt to keep all user results isolated, out-of-the-box the user provider uses the ip address:. You can override something that is very important in a multi-machine production setup :. The string this function returns should be unique for each user on the system for anonymous you may need to fall back to ip address.

You can increase the granularity of profiling by measuring the performance of specific methods. Add methods of interest to an initializer.

It is also possible to profile any arbitrary block of code by passing a block to Rack::MiniProfiler. Single page applications built using Ember, Angular or other frameworks need some special care, as routes often change without a full page load.

To be precise, I am trying to add parameter wrapping to devise controllers. It works great when the application starts, but when I modify one of my controller classes, the parameter wrapping stops working immediately.

As if the controller class was reloaded without the above patch. I had a similar issue before with trying to monkeypatch code that is lazy loaded in rails. I was able to fix it by wrapping my patch in a module then extending the module in the class you are editing. I may have a devise class name wrong, it should match whatever you are trying to monkeypatch. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
