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
