Question

Having a problem with a Paperclip upload in Rails 4 - failing on ForbiddenAttributesError (strong parameters validation). Have the latest paperclip gem and latest rails 4 g

Answer 1

It looks like your first one should have worked. This is what I use for my projects.

class GalleriesController < ApplicationController

  def new
    @gallery = Gallery.new
  end

  def create
    @user.galleries.new(gallery_params)
  end

  private

  #note cover_image is the name of paperclips attachment filetype(s)
  def gallery_params
    params.require(:gallery).permit(:cover_image)
  end
end

Answer 2

I understand what happened here now - and will leave this up in the hope it helps someone else. I was porting code from a rails 3 project and missed the line that created the image:

@image = current_user.images.new(params[:image])

In rails 4 this is incorrect (I beleive). I updated to

@image = current_user.images.new(image_params)

and that solved my problem.
