Wie speichere ich Json Array in HTML-Format in Rails?

Question

Hallo Ruby-Benutzer i JSON-Array-Format

[ 
"Can also work with any bluetooth-enabled smartphones and\ntablets", 
"For calls and music, Hands-free", 
"Very stylish design and lightweight", 
"Function:Bluetooth,Noise Cancelling,Microphone", 
"Compatible:For Any Device With Bluetooth Function", 
"Chipset: CSR4.0", "Bluetooth Version:Bluetooth 4.0", 
"Transmission Distance:10 Meters" 
] 

ich formal dieses Array in HTML mit dem HTML-Format, das unten speichern möchten.

<ul> 
    <li>Can also work with any bluetooth-enabled smartphones and\ntablets</li> 
    <li>For calls and music, Hands-free</li> 
    <li>Very stylish design and lightweight</li> 
    <li>Function:Bluetooth,Noise Cancelling,Microphone</li> 
    <li>Compatible:For Any Device With Bluetooth Function</li> 
    <li>Chipset: CSR4.0</li> 
    <li>Bluetooth Version:Bluetooth 4.0</li> 
    <li>Transmission Distance:10 Meters</li> 
</ul> 

Dies ist meine aktuellen Code, der richtig funktioniert, wenn ich es nur um das Array zu speichern haben aber ich brauche diese HTML-Format zu sein, so Benutzer es leicht

result = JSON.parse(jsonparse) 

result["mods"]["listItems"].each do |result| 
    @item = Item.new 
    @item.item_details = result["description"] 

    @item.save 
end 

Unter meinem Vorherige lesen der Versuch, wie dies

result = JSON.parse(jsonparse) 

result["mods"]["listItems"].each do |result| 
    @item = Item.new 

    item_list = result["description"] 
    item_list.each do |list| 
     @item.item_details = "<li>"+list+"</li>" 
    end 

    @item.save 
end 

Dies zu lösen nur eine der Array speichern und keine <ul> Kopf

herer der ursprüngliche Code

namespace :scraper do 
    desc "Scrape Website" 
    task somesite: :environment do 

    require 'open-uri' 
    require 'nokogiri' 
    require 'json' 

     url = "url here!" 
     page = Nokogiri::HTML(open(url)) 
     script = page.search('head script')[2] 

     jsonparse = script.content[/\{\"[a-zA-Z0-9\"\:\-\,\ \=\(\)\.\_\D\/\[\]\}]+/i] 

     result = JSON.parse(jsonparse) 

     result["mods"]["listItems"].each do |result| 
      @item = Item.new 


      item_details = result["description"].each {|list| "<li>#{list}</li>" } 
      puts item_details 

      @item.item_old_price = result["originalPrice"] 
      @item.item_final_price = result["price"] 

      @item.save 
     end 
    end 
end 

Die Idee ist es, das Array in der Datenbank mit dem HTML-Format zu speichern.

<ul> 
    <li>content 1</li> 
    <li>content 2</li> 
    <li>content and soon</li> 
    </ul> 

Dank

Ich bin mir nicht sicher, was Sie zu tun versucht.

Bitte überprüfen Sie die folgenden Codes und geben Sie mir eine Rückmeldung. Happy coding :)

<!-- language: ruby --> 
require 'json' 

class MyJsonParser 
    def initialize 
    @items = [] 
    end 

    def parse(json) 
    result = JSON.parse(json) 
    generate_items(result) 

    items 
    end 

    private 

    attr_reader :items 

    def generate_items(result) 
    result['mods']['listItems'].each {|item_detail| items << Item.new(item_detail)} 
    end 
end 

class Item 
    attr_reader :details 

    def initialize(detail='') 
    @details = '' 
    before_initialize 
    details << detail 
    after_initialize 
    end 

    private 

    def before_initialize 
    details << '<li>' 
    end 

    def after_initialize 
    details << '</li>' 
    end 
end 

json_str = '{ 
    "mods": { 
    "listItems": 
     [ 
     "Can also work with any bluetooth-enabled smartphones and\ntablets", 
     "For calls and music, Hands-free", 
     "Very stylish design and lightweight", 
     "Function:Bluetooth,Noise Cancelling,Microphone", 
     "Compatible:For Any Device With Bluetooth Function", 
     "Chipset: CSR4.0", 
     "Bluetooth Version:Bluetooth 4.0", 
     "Transmission Distance:10 Meters" 
     ] 
    } 
}' 

result = MyJsonParser.new.parse(json_str) 
result.each do |i| 
    p i.details 
end
