Django Slick Reporting

A one stop reports engine with batteries included.

What it does:

Given a model that contains some data (ex: an OrderLine Model); Slick Reporting allows you to compute any kind of stats (Sum, AVG, etc.. ) over any field using simple and intuitive analogy. It also allow you to use those computation units in a time series and cross tab.

Features

  • Preform Different computation grouping over the foreign keys.

  • Those computation can also be calculated on Time Series report like monthly, with custom dates ability.

  • Computation can be used on Cross tab reports

  • Create your Custom Calculation

  • Optimized for speed !

  • … and much more

Installation

Use the package manager pip to install django-slick-reporting.

pip install django-slick-reporting

Usage

From high Level,

You can use SampleReportView which is a subclass of django.views.generic.FormView like this

# in views.py
from slick_reporting.views import SampleReportView
from .models import MySalesItems

class TotalProductSales(SampleReportView):

    # The model where you have the data
    report_model = MySalesItems

    # the main date to use if date filter is needed
    date_field = 'date_placed' # or 'order__date_placed'
    # date_field support traversing,
    # date_field = 'order__date_placed'

    # A foreign key to group calculation on
    group_by = 'product'

    # The columns you want to display
    columns = ['title', '__total_quantity__', '__total__']

# in your urls.py
path('url-to-report', TotalProductSales.as_view())

This will return a page, with a table looking like

Product

Total Quantity

Total Value

Product 1

8

120

Product 2

13

240

You can also do a monthly time series :

# in views.py
from slick_reporting.views import SampleReportView
from .models import MySalesItems

class MonthlyProductSales(SampleReportView):
    report_model = MySalesItems
    date_field = 'date_placed'
    group_by = 'product'
    columns = ['name', 'sku']

    # Analogy for time series
    time_series_pattern = 'monthly'
    time_series_columns = ['__total_quantity__']

hook it into your urls.py , and it would return a page with a table looking something like this:

Product Name

SKU

Total Quantity in Jan 20

Total Quantity in Feb 20

Total Quantity in …

Total Quantity in December 20

Product 1

<from product model>

10

15

14

Product 2

<from product model>

11

12

12

Product 3

<from product model>

17

12

17

This example code assumes your “MySalesItems” model contains the fields `product` as foreign key, `quantity` as number and `date_placed` as a date field. It also assumes your `Product` model has an SKU field.. Change those to better suit your structure.

On a low level

You can interact with the ReportGenerator using same syntax as used with the SampleReportView .

from slick_reporting.generator import ReportGenerator
from . models import MySalesModel

report = ReportGenerator(report_model=MySalesModel,
                        group_by='product',
                        columns=['title', '__total__']
)
report.get_report_data() #-> [{'title':'Product 1', '__total__: 56}, {'title':'Product 2', '__total__: 43}, ]
