Preamble

In the era of technological development like now, online shopping is extremely developed. We can confirm that even further when the covid-19 pandemic swept, the amazone boss’s fortune has increased by 70 billion dollars. The reason is that people shop more online when isolated, but online shopping needs a reliable trading port instead of ship COD can be flipped orders can cause time and money for business people. Here I would like to introduce about gem active_merchant will help us pay a simple way. Gem is supported by shopify, an extremely large ecommerce platform, and the large developer of ecommerce CMS is Spreedly.

1. Install

Open cmd and create the project.

Create 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

Install gem

cd ecommerce_with_active_merchant

gem install activemerchant

cd ecommerce_with_active_merchant

gem install activemerchant

Then you remember to add the gem file offline

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

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

Create a 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>

We add the action to create in the 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">if</span> <span class="token variable">@order</span> <span class="token punctuation">.</span> save
    <span class="token keyword">if</span> <span class="token variable">@order</span> <span class="token punctuation">.</span> purchase
      render <span class="token symbol">:action</span> <span class="token operator">=</span> <span class="token operator">&gt;</span> <span class="token string">"success"</span>
    <span class="token keyword">else</span>
      render <span class="token symbol">:action</span> <span class="token operator">=</span> <span class="token operator">&gt;</span> <span class="token string">"failure"</span>

    render <span class="token symbol">:action</span> <span class="token operator">=</span> <span class="token operator">&gt;</span> <span class="token string">'new'</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

Create model cart.rb

rails g model cart

1 2	rails g model cart

Because each cart will correspond to an order, we add 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>

has_one :order

end
