Hi,
I got a single form to create an object that can have file attached (I'm using attachment_fu). The problem is with create/update actions. Here's how stripped create action looks like:
def create @news = News.new(params[:news]) @news.asset = Asset.new(params[:asset]) if !params[:asset].blank? && !params[:asset][:uploaded_data].blank?
respond_to do |format| if @news.save format.html { redircet_to news_path } else format.html { render :action => "new" } end end end
In the form I check if @news.asset is not nil and then display a link to the asset (image). There are 2 problems: - if the validation of news object fails, the asset is not saved, but @news.asset is not nil anymore, so I got link displayed to non- existing image - if the validation of news object fails, the file upload fields are empty. If validation fails once again, the params[:asset] hash is empty - this forces user to select a file to upload every time validation fails
How to solve it? Should I save the asset even if validation of news object fails? If yes, how to automatically remove files that are not related to any news object (i.e. the image is saved, validation of news object fails and user simply closes the page without creating news object).
Thanks in advance for any tips
