This article is about How to do simple ruby web scraping by processing CSV.

In this article, we will create a Ruby on Rails application to scrap the link uploaded from a CSV file and find the occurrence of the link on a particular page.

In the below Ruby on Rails application development, the user needs to pass a CSV file and list of the user’s email to whom the parsed CSV will be sent.

In the CSV file, there will be 2 columns

1. referal_link
2. home_link

Let’s start creating a Rails Application

• Run the below command to create a new rails application

$ rails new scrape_csv_data

$ cd scrape_csv_data

• Then, we will generate an Upload CSV module. Run the below command.

$ rails g scaffold UploadCsv generated_csv:string
csv_file:string

This will create all the required models, controllers, and migrations for csv_file. Run the migration using the below command.
