Paginate your Ruby on Rails projects with ease: learn how to do it with a step-by-step example.
Ruby On Rails Pagination
Pagination is a common way to display a large number of records in a single page. In Ruby On Rails, it is very easy to implement pagination with the help of the will_paginate gem.
Adding the Gem
Adding the gem to your Gemfile is the first step in implementing pagination.
gem 'will_paginate', '~> 3.1.0'
Controller Setup
Once the gem is added, you need to add the pagination setup in the controller. This can be done by adding the following code:
def index
@products = Product.paginate(page: params[:page], per_page: 10)
end
In the code above, we are setting the number of products to be displayed per page to 10.
View Setup
In the view, you can use the
will_paginate method to create the pagination links.
<%= will_paginate @products %>
The
will_paginate method will generate the pagination links for you. You can customize the look of the pagination links using the
bootstrap-will_paginate gem.
Routes Setup
The last step is to set up the routes. This can be done using the following code:
resources :products do
get 'page/:page', action: :index, on: :collection
end
The code above will create a route for each page of the pagination. This allows the pagination to work properly.
The above steps are all that is needed to implement pagination in a Ruby On Rails application. Pagination allows you to display a large number of records in a single page, which makes it easier for users to view and navigate the data.
