Powerful and Efficient reporting engine with Charting capabilities

Django Slick Reporting

A one stop reports engine with batteries included.

Features

• Effortlessly create Simple, Grouped, Time series and Crosstab reports in a handful of code lines.
• Create your Custom Calculation easily, which will be integrated with the above reports types
• Optimized for speed.
• Batteries included! Chart.js , DataTable.net & a Bootstrap form.

Installation

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

pip install django-slick-reporting

Usage

So you have a model that contains data, let's call it MySalesItems

You can simply use a code like this

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


# in views.py
from django.db.models import Sum
from slick_reporting.views import SlickReportView
from slick_reporting.fields import SlickReportField
from .models import MySalesItems

class TotalProductSales(SlickReportView):

    report_model = MySalesItems
    date_field = 'date_placed'
    group_by = 'product'
    columns = ['title',
                SlickReportField.create(Sum, 'quantity') ,
                SlickReportField.create(Sum, 'value', name='sum__value') ]

    chart_settings = [{
        'type': 'column',
        'data_source': ['sum__value'],
        'plot_total': False,
        'title_source': 'title',
        'title': _('Detailed Columns'),

    }, ]

To get something like this

You can do a monthly time series :

# in views.py
from slick_reporting.views import SlickReportView
from slick_reporting.fields import SlickReportField
from .models import MySalesItems

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

    # Analogy for time series
    time_series_pattern = 'monthly'
    time_series_columns = [SlickReportField.create(Sum, 'quantity', name='sum__quantity') ]

This would return 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 SlickReportView .

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}, ]
