这是代码，它仍然提交事务，一切似乎都很好

// controller
def avatar_create
  Current.user.avatar.attach(params[:avatar])
  if Current.user.avatar.attached?
    redirect_to root_path
  else
    flash[:alert] = "some thing was wrong"
    render :avatar_new, status: :unprocessable_entity
  end
end

//erb
<%= form_with model: Current.user, url: avatar_path, method: :post do |form|%>
  <%= form.file_field :avatar%>
  <%= form.submit "post"%>
<%end%>
