Rails 4 CSV Import and setting a value to a key value

Question

I\'m a complete Rails n00b and i\'m sure this is an easy thing to do but i\'m having trouble. I would like to take the value of a key in my URL and set it to the :category_i

Answer 1

if the class method import is called in the import controller action, you can pass params[:category_id] as the 2nd parameter.

class ManufacturersController < ApplicationController
  def import
    Manufacturer.import(params[:file], params[:category_id])
  end
end

class Manufacturer < ActiveRecord::Base
  def self.import(file, category_id)
    CSV.foreach(file.path, headers: true) do |row|
      record = Manufacturer.where(
        :category_id => category_id,
        :name => row[0]
      ).first_or_create
    end
  end
end
