The thing is that I want to let the user delete an image he might have uploaded before he presses the submit button. Is that possible? For what I've read, the way to delete the image is to set projecte.image=nil before a project.save (which is done when the form is submitted). How could I let the user do that before the submit? Any ideas would be appreciated!
I generally put a checkbox on the form (a normal checkbox not tied to the model or anything. I.E.
<%= check_box_tag 'remove_image' %>
Then in my "update" action I put the following:
@project = Project.find params[:id] @project.attributes = params[:project] @project.image = nil if params[:remove_image] if @project.save flash[:notice] = "Project #{@project} sucessfully updated" redirect_to projects_path else render :action => 'edit end
So basically we just have an extra param to flag the image for removal.
