Rails - Mar 2011 - I'm failing to create an instance of an has_many-associated model

Hi,

I''m pretty much of a rails newbie and ss the title says I''m
failing at very
basic things.

Anyway. I have 2 models ''article'' and
''upload''. Article has_many :uploads
Now I''m trying to create an instance of upload in an article in my 
articles_controller like this:

class ArticlesController < ApplicationController

  def upload
    @article = Article.find(params[:id])
    @article.uploads.create(params[:file])
    render :nothing => true
  end

end

If I submit a file to articles/1/upload I get a NoMethodError

You have a nil object when you didn''t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.delete

app/controllers/articles_controller.rb:95:in `upload''

where line 95 is @article.uploads.create(params[:file])

Does anyone have an idea what''s wrong?

Thanks

Lukas

Ok, Hates_ from the IRC helped me. It was params[:file] that was nil
