A one stop reports engine with batteries included.

• 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! Charts.js , DataTable.net & a Bootstrap form.

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

pip install django-slick-reporting

From high Level,

You can use SampleReportView which is an enhanced subclass of ``django.views.generic.FormView`` like this

# in views.py
from django.db.models import Sum
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'
    # date_field support traversing, you can
    # date_field = 'order__date_placed'

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

    # The columns you want to display , `quantity` and `value` are fields on `MySalesItem` model.
    columns = ['title', BaseReportField.create(Sum, 'quantity') , BaseReportField.create(Sum, 'value') ]

    # Another way making use of the built-in Report Fields which is identical to the above
    # 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

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__']

This would return a table looking something like this:

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}, ]

This is just a scratch, for more please visit the documentation

Slick Reporting comes with

• A Bootstrap Filter Form
• Charting support Charts.js
• Powerful tables datatables.net

A Preview:

Available on Read The Docs

This project is young and can use your support.

Some of the ideas / features that ought be added

• Support Other backends like SQL Alchemy & Pandas
• Support Grouping by non foreign key fields
• Support Time Series and Crosstab at the same time

Create a virtual environment (maybe with virtual slick_reports_test), activate it; Then ,

$ git clone git+git@github.com:ra-systems/django-slick-reporting.git
$ cd tests
$ python -m pip install -e ..

$ python runtests.py
#     Or for Coverage report
$ coverage run --include=../* runtests.py [-k]
$ coverage html

Please consider star the project to keep an eye on it. Your PRs, reviews are most welcome and needed.

We honor the well formulated Django's guidelines to serve as contribution guide here too.
