Hi there, I posted this issue <https://groups.google.com/forum/?hl=de#!topic/carrierwave/ergk9LaO68k>at the carrierwave-group, but I'm beginning to think this rather is a rails-issue than a problem with carrierwave. The problem's this:
I have 2 models, 'article' and 'upload'. article has_many :uploads. In my article_controller i have an action named upload: def upload @article = Article.find(params[:id]) @article.uploads.create(params[:file]) render :nothing => true end this should save a file-upload to article.uploads. I'm using carrierwave to save uploads in the upload-model, but that's probably not the problem. Before I created the has_many-association I saved the upload directly in the article-model using params[:file] in that exact same action and that worked great. Now that I created the association there seems to be a problem with params[:file]. I keep getting 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]) if I remove the parameter no errors get thrown. But the console tells me params[:file] DOES exists and has proper values. Also params[:file] worked great before I used the has_many association. I have no clue what the problem could be. Can anyone give me a hint? Thanks, Lukas -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
