Mở đầu

Ở thời đại công nghệ phát triển như bây giờ, shopping online đang cực kỳ phát triển. Ta có thể khẳng định điều đó hơn nữa khi đại dịch covid-19 càn quét, khối tài sản của ông chủ amazone đã tăng thêm tới 70 tỷ đô. Lý do là mọi người mua sắm online nhiều hơn khi cách ly, mà mua sắm online thì cần có 1 cổng giao dịch đáng tin cậy thay vì ship COD có thể bị bùng đơn hàng gây mất thời gian và tiền bạc cho người kinh doanh. Sau đây mình xin giới thiệu về gem active_merchant sẽ giúp chúng ta thanh toán 1 cách đơn giản. Gem được support bởi nền tảng ecommerce cực kỳ lớn shopify, và nhà phát triển của CMS ecommerce cũng khá lớn đó là Spreedly.

1. Cài đặt

Mở cmd và tạo project nhé.

Tạo project

rails <span class="token keyword">new</span> <span class="token class-name">app</span> ecommerce_with_active_merchant

1 2	rails <span class="token keyword">new</span> <span class="token class-name">app</span> ecommerce_with_active_merchant

Cài đặt gem

cd ecommerce_with_active_merchant

gem install activemerchant

cd ecommerce_with_active_merchant

gem install activemerchant

Sau đó các bạn nhớ thêm vào gem file nhé

gem <span class="token string">'activemerchant'</span>

1 2	gem <span class="token string">'activemerchant'</span>

Tạo model

rails g scaffold order <span class="token keyword">new</span> cart_id<span class="token symbol">:integer</span> ip_address<span class="token symbol">:string</span> first_name<span class="token symbol">:string</span> last_name<span class="token symbol">:string</span> card_type<span class="token symbol">:string</span> card_expires_on<span class="token symbol">:date</span>

Ta thêm action xử lý create trong controller

<span class="token keyword">def</span> <span class="token method-definition"><span class="token function">create</span></span>
  <span class="token variable">@order</span> <span class="token operator">=</span> current_cart<span class="token punctuation">.</span>build_order<span class="token punctuation">(</span>params<span class="token punctuation">[</span><span class="token symbol">:order</span><span class="token punctuation">]</span><span class="token punctuation">)</span>

  <span class="token keyword">end</span>
<span class="token keyword">end</span>

def create

@order = current_cart.build_order(params[:order])

@order.ip_address = request.remote_ip

if @order.save

if @order.purchase

render :action => "success"

else

render :action => "failure"

end

else

render :action => 'new'

end

Tạo model cart.rb

rails g model cart

1 2	rails g model cart

Vì mỗi cart sẽ ứng với 1 order nên ta thêm relation

<span class="token keyword">class</span> <span class="token class-name">Cart</span> <span class="token operator">&lt;</span> <span class="token constant">ApplicationRecord</span>
  has_one <span class="token symbol">:order</span>

class Cart < ApplicationRecord

has_one :order

end
