Code Example: Building a Simple Blog with Ruby on Rails
Here is an example of how to build a simple blog using Ruby on Rails:
# models/user.rb
class User < ApplicationRecord
validates :name, presence: true
validates :email, uniqueness: true
end
# controllers/user_controller.rb
class UsersController < ApplicationController
def index
@users = User.all
end
def show
@user = User.find(params[:id])
end
def create
@user = User.new(user_params)
if @user.save
redirect_to @user, notice: 'User created successfully'
else
render :new
end
end
private
def user_params
params.require(:user).permit(:name, :email)
end
end
# views/users/index.html.erb
<h1>Users</h1>

</tr>
</thead>
<tbody>
<% @users.each do |user| %>
<tr>
<td><%= user.name %></td>

</tr>
<% end %>
</tbody>
</table>
<%= form_for(@user) do |form| %>
<%= form.text_field :name %>
<%= form.text_field :email %>
<%= form.submit %>
