我如何了解Actionpack并使用Rails对其进行调试

Question

When i reading the source code,I was just not concept or not way to debuging. To be exact ,I wouldn't know where to begin.

My understanding is:

First I need to read is the routing. But i don't know where is initialization Routes when starting the service. I tried to start with Rake understanding. But I don't know how to correlate them. It is important, I don't know how they interact . I only know superficial concept, ... What should I do next?

Thank you for your time.

Answer 1

The routes are usually defined in config/routes.rb and you can test that they're working correctly by running rake routes to see how they're interpreted.

If you keep your routing table simple, which is best done by following a strict REST-ful approach, then you'll have entries like:

resources :users

If you diverge from the REST-ful approach, which is sometimes necessary, be aware that it will complicate your routing file, so be cautious before doing this.

rake is a general utility used by Rails and other Ruby applications to perform utility functions. In the Rails world it's primarily used for executing rake test and rake routes as most of the other functions are handled by the rails command itself.

I would start with reading some Rails Guides ( http://guides.rubyonrails.org/ )

Debugging Rails Applications would be a good start http://guides.rubyonrails.org/debugging_rails_applications.html
