Python/Django Question

Job ID: 36063220

Budget: $30 – $250 USD

We are looking for someone who is an expert in Python/Django to assist us.

We have a model, SaleItems.
In the model we have (department__department_name, category__category_name, item_total).

I need to display the 'item_total' sum for the department and then underneath it, each category_id in that department.

The departments are on the blue lines and the category colors are underneath.

We are looking to display the data just as shown here.
