How to save results into the database? - ruby-on-rails

Question

I created a web scraper.
I'm struggling to save the results into the model's columns.
How do I push the results of the scrapped results into the columns?
Do you map it? Would like to understand it so I can eventually post to index perhaps ... or show previous saved results, etc ...
Schema
ActiveRecord::Schema.define(version: 20170308223314) do
# These are extensions that must be enabled in order to support this database
enable_extension "plpgsql"
create_table "links", force: :cascade do |t|
t.string "link_info"
t.string "date"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
end
The two columns that I'm trying to save to are the ones you see in the schema above: link_info and date ...
Current Controller
class LinksController < ApplicationController
def craigslist_scrape
require 'open-uri'
url = "https://losangeles.craigslist.org/search/web"
page = Nokogiri::HTML(open(url))
#craigslist_info = page.css("ul.rows")
#link_info = page.css("li.result-row p.result-info a.result-title.hdrlnk")
#date = page.css("li.result-row p.result-info time.result-date")
end
end
craiglist_scrape.html.erb
<% #link_info.each_with_index do |link, index| %>
<h2><%= "Title of the job: #{link.text}" %></h2>
<p><%= "Date: #{#date[index].text}" %></p>
<% end %>
routes
Rails.application.routes.draw do
root 'links#craigslist_scrape'
end
model
class Link < ApplicationRecord
end

Answer 1

In the controller you can add:
def craigslist_scrape
require 'open-uri'
url = "https://losangeles.craigslist.org/search/web"
page = Nokogiri::HTML(open(url))
#craigslist_info = page.css("ul.rows")
#link_info = page.css("li.result-row p.result-info a.result-title.hdrlnk")
#date = page.css("li.result-row p.result-info time.result-date")
#link_info.each_with_index do |link, index|
Link.new(:link => link.text, :date => #date[index].text).save
end
end

I'm rather new to Ruby and don't know much about Rails but what I always do when I'm trying to save something into a "database" is I create a hash. For example:
database = {}
puts "What is your name?"
input = gets.chomp
puts "What's your age?"
input_2 = Integer(gets.chomp)
database[input.to_sym] = input_2
In the example above I create a hash called "database" and I ask the user for their name and age. Storing the user's name as the string value for database and their age as an integer value. I don't know if this helps at all, like I said I'm fairly new to Ruby.
