How to Perform Data Scraping in Rails by Processing CSV

Now let's delve into the process of implementing data scraping in Rails by processing CSV files.

Step 1: Setting Up your Rails Application

To begin, ensure that you have a functional Rails application set up on your system. If not, follow the official Rails documentation to create a new Rails project.

Step 2: Installing Necessary Gems

Next, install the required gems for data scraping and CSV processing in your Rails application. The most commonly used gems are 'nokogiri' and 'csv.'

Step 3: Collecting Data from CSV

Start by creating a model to handle the data collection process. Define the necessary model attributes, such as column names and data types, to structure the scraped data.

Step 4: Scraping Data from Websites

Utilize the 'nokogiri' gem to scrape data from the desired websites. Identify the HTML elements that contain the information you need and extract them using the appropriate methods and selectors.

Step 5: Processing CSV

After scraping the necessary data, process it by leveraging the 'csv' gem. Convert the scraped data into CSV format and save it in a file or database for further analysis or integration.

Step 6: Automating the Process

To ensure regular and efficient data scraping, consider implementing automation techniques, such as scheduled jobs or background processing using gems like 'sidekiq' or 'whenever.'
