Using nested controllers

Question

Since my site had an admin section and a normal (front-end user) section, I needed to structure the articles controller in such a way that it was RESTful.

So what I did was , have 2 articles controllers, 1 nested under the admin namespace (which would result in admin/articles) and the other one as a normal articles resource (/articles). (I followed this blog.)

Now I started facing issues such as

A copy of AuditObserver has been removed from the module tree but is still active!

2 questions .

1. Is this error really because of me using such a structure of nested resources?
2. Is it a good programming practice to use such a structure? If not, is there a better alternative?

Thanks!

The structure is perfectly fine, and your code will probably function just fine in production mode. The issue usually arises in development when modules or classes are not 'unloaded' after a first request. Without seeing the code it's hard to tell exactly which module or plugin might be causing this issue, but you might want to have a look at this blog post.

You can usually solve this issue by loading the offending module or class only once:

config.autoload_once_paths << '/path/to/class/or/module.rb'

or by reloading your plugins in development mode:

config.reload_plugins = true if Rails.env == 'development'
