Posted 2021-05-16

Rails.application.routes.draw do

  root to: 'domains#index'

  resources :domains do
    collection { post :import }
  end

  <h3>Import Domains</h3>
  <%= form_tag import_domains_path, multipart: true do %>
    <%= file_field_tag :file %>
    <%= submit_tag "Upload Domains" %>
  <% end %>
</div>

def import
    Domain.import(params[:file])
    redirect_to root_url, notice: "Domains added successully."
  end

class Domain < ActiveRecord::Base
  belongs_to :creator, class_name: 'User', foreign_key: 'user_id'

  def self.import(file)
    CSV.foreach(file.path, headers: true) do |row|
      Domain.create! row.to_hash
    end
  end
  
end
