Implementing pagination for orders in a Ruby on Rails Shopify app

Hey folks, I’m new to Ruby and I’m working on a Shopify app using Ruby on Rails. I have an orders table that currently lists every order, which is overwhelming. I need a solution that only loads a limited set of orders per page without fetching them all at once.

I tried a JavaScript approach initially, but it ended up loading every order anyway. I am now looking for a native Ruby solution that can implement efficient pagination.

Here’s an example of what I have so far:

class OrdersController < ApplicationController
  def index
    @orders = ShopifyAPI::Order.all
  end
end

This example loads all orders. I need a way to limit the dataset and provide page navigation. Any advice on how to set up efficient pagination in Ruby on Rails?

As someone who’s worked extensively with Shopify APIs and Rails, I can offer some insights. The key here is to leverage Shopify’s pagination system directly. Instead of fetching all orders at once, you should use the limit and since_id parameters.

Here’s a basic implementation:

class OrdersController < ApplicationController
  def index
    @page = params[:page].to_i || 1
    @limit = 50
    @orders = ShopifyAPI::Order.find(:all, params: {
      limit: @limit,
      page: @page
    })
    @next_page = @page + 1 if @orders.next_page?
  end
end

This approach fetches orders in batches of 50 (adjust as needed). It’s much more efficient as it only retrieves the necessary data for each page.

In your view, you can then add simple navigation:

<%= link_to 'Next Page', orders_path(page: @next_page) if @next_page %>

Remember to handle edge cases like empty result sets. This method has served me well in several Shopify projects, balancing performance and usability.
