I'm trying to save news data for stocks from an api to my "Headline" database. But I think my controller params are wrong and so I can't populate an item to save to my table.

I've tried changing the @headline = Headline.new_from_lookup(params[:stock]) params to :ticker :symbol but nothing changes. Still getting undefined method `save' for nil:NilClass

Routes.rb

Rails.application.routes.draw do
# The priority is based upon order of creation: first created -> highest priority.
# See how all your routes lay out with "rake routes".

root 'headlines#new'

resources :headlines

end

headline.rb

class Headline < ActiveRecord::Base
require 'iex-ruby-client'

def self.new_from_lookup(symbol)
 begin
 looked_up_stock = IEX::Resources::Quote.get(symbol)
 looked_up_news = IEX::Resources::News.get(symbol)
 new(ticker: looked_up_stock.symbol, name: looked_up_stock.companyName, headline: looked_up_news.first.headline, summary: looked_up_news.first.summary, url: looked_up_news.first.url)
 rescue Exception => e
 return nil
 end
end

end

headline_controller.rb

class HeadlinesController < ApplicationController

def new
 @headline = Headline.new
end

def create
 # takes input from the search page then finds the stock info with the model headline.rb
 @headline = Headline.new_from_lookup(params[:symbol])

 @headline.save # saves the headline info to the database

 redirect_to headline_path(@headline) # directs the user to the show path
end

def show
 @headline = Headline.find(params[:id]) # shows the news from the database that was just entered
end

end

  Can you modify the post. It is hard to read, it would make it easier if you use the tools to insert code snippets.

Instead of

rescue Exception => e
 return nil
 end

write

rescue Exception => e
 puts e.message
 puts e.stacktrace.join("n")
 return nil
 end

at least you can see what error you have

plus in controller you need to check later if object is nil
