Creating a global digital voting application in Ruby involves several components, including user authentication, a voting mechanism, and possibly a way to verify votes while ensuring security and privacy. Below is a simplified version of how such an application could be structured using Ruby on Rails, a popular web application framework.
This example doesn't include all possible security measures or features, which are crucial in a real-world voting application.
### Step-by-Step Guide to Create a Basic Voting Application
#### 1. **Set Up Your Environment**
First, ensure you have Ruby and Rails installed on your machine. If you haven’t already, you can install Rails by running:
```bash
gem install rails
```
Then create a new Rails application:
```bash
rails new GlobalVotingApp
cd GlobalVotingApp
```
#### 2. **Generate Models**
You’ll need models to represent Users and Votes. For simplicity, assume each user can vote on a single topic.
```bash
rails generate model User name:string email:string:uniq
rails generate model Vote user:references topic:string choice:string
rake db:migrate
```
#### 3. **Set Up Associations**
Open the generated model files and establish relationships:
**app/models/user.rb**
```ruby
class User < ApplicationRecord
has_many :votes
validates :email, presence: true, uniqueness: true
end
```
**app/models/vote.rb**
```ruby
class Vote < ApplicationRecord
belongs_to :user
validates :topic, presence: true
validates :choice, presence: true
end
```
#### 4. **Controller Creation**
You will need a controller to handle voting.
```bash
rails generate controller Votes
```
**app/controllers/votes_controller.rb**
```ruby
class VotesController < ApplicationController
before_action :set_vote, only: [:show, :update]
def index
@votes = Vote.all
end
def create
@vote = Vote.new(vote_params)
@vote.user = current_user # Assuming you have user authentication
if @vote.save
redirect_to votes_path, notice: 'Vote was successfully cast.'
else
render :new
end
end
private
def set_vote
@vote = Vote.find(params[:id])
end
def vote_params
params.require(:vote).permit(:topic, :choice)
end
end
```
#### 5. **User Authentication**
While this example doesn’t include a full-blown user authentication system, you can use Devise or similar libraries to manage user sign-ups and logins.
Add Devise to your Gemfile:
```ruby
gem 'devise'
```
Run the installation script:
```bash
rails generate devise:install
rails generate devise User
rake db:migrate
```
With Devise set up, you can manage users.
#### 6. **Create Views**
Create simple forms to allow users to cast their votes.
**app/views/votes/new.html.erb**
```erb
<h1>Cast Your Vote</h1>
<%= form_with model: @vote, local: true do |form| %>
<div>
<%= form.label :topic %>
<%= form.text_field :topic %>
</div>
<div>
<%= form.label :choice %>
<%= form.text_field :choice %>
</div>
<div>
<%= form.submit "Vote" %>
</div>
<% end %>
```
**app/views/votes/index.html.erb**
```erb
<h1>All Votes</h1>
<table>
<thead>
<tr>
<th>User</th>
<th>Topic</th>
<th>Choice</th>
</tr>
</thead>
<tbody>
<% @votes.each do |vote| %>
<tr>
<td><%= vote.user.name %></td>
<td><%= vote.topic %></td>
<td><%= vote.choice %></td>
</tr>
<% end %>
</tbody>
</table>
```
#### 7. **Routes**
Configure your routes in `config/routes.rb`:
```ruby
Rails.application.routes.draw do
devise_for :users
resources :votes
root 'votes#index'
end
```
#### 8. **Run Your Application**
Start your Rails server:
```bash
rails server
```
You can visit `http://localhost:3000` and test your application.
### Important Considerations
- **Security**: This example lacks important security features such as data encryption, vote verification, and protection against unauthorized voting. In a real-world scenario, you would need to implement these measures.
- **Scalability**: A global voting app must be scalable and able to handle a large number of users and votes efficiently.
- **Privacy**: Ensure the anonymity of voters if required.
- **Auditability**: Consider implementing an audit trail for votes, so they can be verified and contested if necessary.
### Conclusion
This is a very basic structure for a voting app, and it's vital to incorporate security, privacy, and data integrity considerations before deploying an application intended for real-world voting. Using technologies such as blockchain could also enhance the security and transparency of votes in a global digital voting system. Additionally, consulting with legal and cybersecurity experts would be essential when building such an application.
