Installation

Run following command to install DjangoQtt :

pip install django-query-to-table

Example usage :

• Generate HTML table by SQL query:

from django_query_to_table import DjangoQtt
from django.http import HttpResponse

# view function in Django project
def listOfPersons(request):
  reportTitle = "Employee List"
  sqlQuery = "SELECT FirstName as 'First Name', LastName as 'Last Name', phone as 'Phone Number', salary as 'Salary' FROM persons"
  columnsToBeSummarized = ['Salary']
  fontName = "Arial"
  cssClasses = "reportTable container"
  headerRowBackgroundColor = '#ffeeee'
  evenRowsBackgroundColor = '#ffeeff'
  oddRowsBackgroundColor = '#ffffff'
  rowIndexVisibility = True
  table = DjangoQtt.generate_from_sql(reportTitle, sqlQuery, columnsToBeSummarized, cssClasses,
                                  "ltr", fontName, "Total Salary", rowIndexVisibility,
                                  headerRowBackgroundColor, evenRowsBackgroundColor, oddRowsBackgroundColor
                                  )
  
  # here the table is a string variable containing the html table showing the query result
  return HttpResponse(table)
   

Since Django 4.0.4 introduced a security fix that disallows spaces in aliases, you can use double underscores (__) as a substitute in your aliases. The table generator will automatically display them as spaces in the output. Here's an example:

• Generate HTML table from querset:

from django_query_to_table import DjangoQtt
from django.http import HttpResponse
from .models import Order
# view function in Django project
def listOfPersons(request):

  order_queryset = Order.objects.annotate(
      **{
         'Order__Number': F('order_number'),
         'Order__Item': F('order_item'),
         'Customer__Name': F('customer_name'),
         'Order__Date': F('order_date'),
         'Total__Amount': F('total_amount'),
      }
   ).values(
      'Order__Number',
      'Order__Item',
      'Customer__Name',
      'Order__Date',
      'Total__Amount'
   )

  table = DjangoQtt.generate_from_queryset(
                                       title = "Summmary Table",
                                       queryset = order_queryset,
                                       htmlClass = "summary",
                                       rowIndex = True,
                                       footerCols=['Total__Amount'],

                                    )
  
  return HttpResponse(table)
   

The table will be look like this:
