to_model delegated to attachment, but attachment is nil

Question

So I asked this question already here: previous question and didn\'t get much help, I looked for other questions similar to mine, but no resolution. So I\'ll ask the question ag

Answer 1

It seems that you don't have a banner image for the user. If your view layout breaks because the user has no banner so use conditional if in your code

image_tag url_for(@user.banner_image) if @user.banner_image.present?

Or you may want to have a fallback image to preserve the layout

image_tag url_for(@user.banner_image || '/public/fallback_banner_image.jpg')

The above line is an example but you will need to include an actual file image/path

Answer 2

ISSUE RESOLVED:

  # If you have extra params to permit, append them to the sanitizer.
  def configure_sign_up_params
    devise_parameter_sanitizer.permit(:sign_up, keys: [:firstname, :image])
  end

  # If you have extra params to permit, append them to the sanitizer.
  def configure_account_update_params
    devise_parameter_sanitizer.permit(:account_update, keys: [:firstname, :image])
  end

so the configure_account_update_params defenition was set to permit the :signup not :account_update. I changed it to :account_update and it worked!
