    }

In model,

include HTTParty

In controller

def index  
  require 'httparty'
  @category = HTTParty.get(
    'http://codekyt.in/froodle-wp/wp-json/data/v2/projects?client_key=12345',
    :headers =>{'Content-Type' => 'application/json'}
  )
end

In gemfile,

gem 'httparty'
gem 'json'

In view,

<%@category.each do |category|%>
<%=category["restaurant_name"]%>
<%=category["country"]%>
<%=category["currency"]%>
<%=category["usd"]%>
<%=category["client_key"]%>
<%=category["client_name"]%>
<%=category["client_email"]%>
<%=category["client_phone"]%>
<%=category["product_tier"]%>
<%=category["brand_logo_large"]%>
<%end%>

Answer 1

HTTParty.get returns an encapsulated response type of class HTTParty::Response , you need to retrieve the parsed response from that by:

response = HTTParty.get(
  'http://codekyt.in/froodle-wp/wp-json/data/v2/projects?client_key=12345',
  :headers =>{'Content-Type' => 'application/json'}
)
@category = response.parsed_response # this will return the json.

Also you do not need to iterate on @category in your case, the json object is singular and you can directly use it:

<%=@category["restaurant_name"]%>
<%=@category["country"]%>
<%=@category["currency"]%>
<%=@category["usd"]%>
<%=@category["client_key"]%>
<%=@category["client_name"]%>
<%=@category["client_email"]%>
<%=@category["client_phone"]%>
<%=@category["product_tier"]%>
<%=@category["brand_logo_large"]%>
