Carrierwave upload with nested forms?

Question

Not sure what\'s going on here, but I think my nested form partials are causing a problem for CarrierWave.

When I update a field with an uploaded file, nothing happe

Some possible solutions:

• It looks like you have, but just to make sure - have you got accepts_nested_attributes on the household model?
• Also, have you tried it without the partial to localise the problem?
• Have you got Rmagick or minimagick on the PictureUploader model?

And also you'll want to note of the known issue with Carrierwave and nested forms as detailed on the Carrierwave Wiki.

The workaround is to add the method below:

class Image < ActiveRecord::Base
  mount_uploader :image, ImageUploader

  def image=(val)
    if !val.is_a?(String) && valid?
      image_will_change!
      super
    end
  end

end
class Person < ActiveRecord::Base
  has_many :images
  accepts_nested_attributes_for :images
end
