Raptor in Rails?

comments_controller.rb

class CommentsController < ApplicationController

  def create
    @article = Article.find(params[:article_id])
    @comment = @article.comments.build(params[:comment])
    @comment.save # etc
  end

end

# I simply want this

class CommentsController < ApplicationController

  def create(article, comment)
    comment.article = article
    comment.save # etc
  end

end

# Maybe Raptor + Rails can do it?

You could theoretically use Raptor's injector in a controller base class that your controllers inherit from. But fighting Rails is usually a bad idea...

Do you think this is really fighting Rails?

It already has a hook just for that.

I'm pretty sure Rails likes fighting... ;)

I don't know; I have little experience with this myself. But the idea of trying to hook into ActionController::Base makes me tired.
