🚀 PROMO: Junior Developers Starter KIT 85%OFF

The package includes a rock-solid collection of premium assets (Kits & Dashboards) that can be used to build eye-catching portfolios and web apps in no time.

Base Requirements

• Install django-import-export package to import data form csv, xls and etc file to table.

$ pip install django-import-export

Then add this package to INSTALLED_APPS in settings.py. Now you can change the admin section of each model and add this feature. so you can easily import the data to your table. Please add this package in requirements.txt

REST API

How to use it

To use REST in Django, install djangorestframework: ‍‍‍

$ pip install djangorestframework djangorestframework-simplejwt

In settings.py add rest_framework in INSTALLED_APPS

INSTALLED_APPS = [
    ...
    'rest_framework',
]

Then add django rest framework config in settings.py:

REST_FRAMEWORK = {
    'PAGE_SIZE': 5,
    'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.LimitOffsetPagination',
    'COERCE_DECIMAL_TO_STRING': False,
}

Please add this package in requirements.txt

Database/table structure

Create two models to display the information in REST API, which includes Visit & Traffic:

from django.db import models

class Visit(models.Model):
    BOUNCE_RATE_TYPE_UP = 1
    BOUNCE_RATE_TYPE_DOWN = 2

    BOUNCE_RATE_TYPE_CHOICES = [
        (BOUNCE_RATE_TYPE_UP, 'up'),
        (BOUNCE_RATE_TYPE_DOWN, 'down')
    ]

    page_name        = models.CharField(max_length=255)
    visitors         = models.PositiveIntegerField()
    unique_users     = models.PositiveIntegerField()
    bounce_rate      = models.FloatField()
    bounce_rate_type = models.SmallIntegerField(choices=BOUNCE_RATE_TYPE_CHOICES)
    created_time     = models.DateTimeField(db_index=True)
    updated_time     = models.DateTimeField(auto_now=True)

    class Meta:
        verbose_name = 'visit'
        verbose_name_plural = 'visits'

class Traffic(models.Model):
    RATE_TYPE_UP = 1
    RATE_TYPE_DOWN = 2

    RATE_TYPE_CHOICES = [
        (RATE_TYPE_UP, 'up'),
        (RATE_TYPE_DOWN, 'down')
    ]

    referral     = models.CharField(max_length=50)
    visitors     = models.PositiveIntegerField()
    rate         = models.FloatField()
    rate_type    = models.SmallIntegerField(choices=RATE_TYPE_CHOICES)
    created_time = models.DateTimeField(db_index=True)
    updated_time = models.DateTimeField(auto_now=True)

    class Meta:
        verbose_name = 'traffic'
        verbose_name_plural = 'traffics'

Files (that implements the feature)

• Create serializers.py file. Then add serializers TrafficSerializer and VisitSerializer as follows:

from rest_framework import serializers
from app.models import Traffic, Visit

class TrafficSerializer(serializers.ModelSerializer):
    class Meta:
        model = Traffic
        fields = '__all__'

class VisitSerializer(serializers.ModelSerializer):
    class Meta:
        model = Visit
        fields = '__all__'

• In file views.py add the TrafficViewSet and VisitViewSet ViewSets.

from rest_framework.viewsets import ModelViewSet
from app.models import Traffic, Visit
from app.serializers import TrafficSerializer, VisitSerializer


class TrafficViewSet(ModelViewSet):
    serializer_class = TrafficSerializer
    queryset = Traffic.objects.all()
    http_method_names = ['get']


class VisitViewSet(ModelViewSet):
    serializer_class = VisitSerializer
    queryset = Visit.objects.all()
    http_method_names = ['get']

• In file urls.py, add the following urls:

from rest_framework import routers
from app.views import TrafficViewSet, VisitViewSet

router = routers.SimpleRouter()
router.register(r'api/v1/traffics', TrafficViewSet, basename="traffics")
router.register(r'api/v1/visits', VisitViewSet, basename="visits")

urlpatterns = router.urls + [
...
]

Now your REST APIs is ready. And you can use it.

API structure

The traffics and visits APIs structure follow the Django REST framework:

{
    "count": "Total Item count",
    "next": "Next Link",
    "previous": "Previous Link",
    "results": "Serialized information in the form of a list"
}

How to add data

In Django admin, you can import data for the Visits and Traffics sections. To do this just click on IMPORT button in each section, then select your csv, xls or etc file and submit it.

Download Visits and Traffics Sample data

How to consume API

• To use AIPs, you can import the sample POSTMAN

GraphQL API

How to use it

To use GraphQL in Django install graphene-django:

$ pip install graphene-django

In settings.py add graphene-django in INSTALLED_APPS

INSTALLED_APPS = [
    ...
    'graphene_django',
]

Please add this package in requirements.txt

Database/table structure

We created two models to display the information in GraphQL API, which includes Order & Sale:

from django.db import models

class Order(models.Model):
    count        = models.PositiveIntegerField()
    amount       = models.FloatField(db_index=True)
    product_name = models.CharField(max_length=40, db_index=True)
    created_time = models.DateTimeField(db_index=True)
    updated_time = models.DateTimeField(auto_now=True)

    class Meta:
        verbose_name = 'order'
        verbose_name_plural = 'orders'


class Sale(models.Model):
    amount       = models.FloatField(db_index=True)
    product_name = models.CharField(max_length=40, db_index=True)
    created_time = models.DateTimeField(db_index=True)
    updated_time = models.DateTimeField(auto_now=True)

    class Meta:
        verbose_name = 'sale'
        verbose_name_plural = 'sales'

Files (that implements the feature)

• Create the schema.py file in your app. Then add the following classes to make your own schema:

These classes include monthly reports on sales and orders.

import graphene
from django.db.models import Count, Sum
from django.db.models.functions import TruncMonth
from app.models import Order, Sale


class OrderMonthReportType(graphene.ObjectType):
    month = graphene.Int()
    total = graphene.Int(name='total')

class SalesMonthReportType(graphene.ObjectType):
    month = graphene.Int()
    total_amount = graphene.Float(name='total_amount')

class Query(graphene.ObjectType):
    orders_month_report = graphene.List(
        OrderMonthReportType,
        name='orders_month_report'
    )

    sales_month_report = graphene.List(
        SalesMonthReportType,
        name='sales_month_report'
    )

    def resolve_orders_month_report(self, info, **kwargs):
        queryset = Order.objects.annotate(
            date=TruncMonth('created_time')
        ).values('date').annotate(total=Count('id')).values('date', 'total').order_by('date')

        report = {month: 0 for month in range(1, 13)}
        for order_month in queryset:
            report[order_month['date'].month] += order_month['total']
        report = sorted(report.items())

        res = []
        for month, total in report:
            res.append({'month': month, 'total': total})

        return res

    def resolve_sales_month_report(self, info, **kwargs):
        queryset = Sale.objects.annotate(
            date=TruncMonth('created_time')
        ).values('date').annotate(total_amount=Sum('amount')).values('date', 'total_amount').order_by('date')

        report = {month: 0 for month in range(1, 13)}
        for order_month in queryset:
            report[order_month['date'].month] += round(order_month['total_amount'], 2)
        report = sorted(report.items())

        res = []
        for month, total_amount in report:
            res.append({'month': month, 'total_amount': total_amount})

        return res

• To receive data through any app, you need to create a schema.py file in the main app. In this project, the name of the main app is core. So in this part, I created a scheam.py:

import graphene
from app.schema import Query as app_query

class Query(app_query):
    pass

schema = graphene.Schema(query=Query)

• Then add the url in urls.py in main app:

from django.contrib import admin
from django.urls import path
from django.views.decorators.csrf import csrf_exempt
from graphene_django.views import GraphQLView
from core.schema import schema

urlpatterns = [
    path('admin/', admin.site.urls),
    
    # This is our GraphQL URL
    path('graphql/', csrf_exempt(GraphQLView.as_view(graphiql=True, schema=schema))),
]

We enabled ‍‍‍graphiql to run queries with graphiql=True

• Now you can open http://localhost:8000/graphql/ in your browser and run your queries.

Sample Query:

{
  orders_month_report{
    total
    month
  }
  sales_month_report{
    total_amount
    month
  }
}

API structure

The orders and sales APIs structure follow the Django GraphQL:

{
  "data": {
    "orders_month_report": [],
    "sales_month_report": []
  }
}

How to add data

In Django admin, you can import data for the Orders and Sales sections. To do this just click on IMPORT button in each section, then select your csv, xls or etc file and submit it.

Download Orders and Sales Sample data

How to consume API

• To use AIPs, you can import the sample POSTMAN

Charts Samples

For this part, we use GraphQL API and Jquery (AJAX) to fetch data and show.

Database/table structure

• In this section, we use the previous models, ie Order and Sale.

Files (that implements the feature)

• Create a new js file (anywhere you want). named dashboard.js and add it in the page you want to fetch and show.
• Run AJAX when the page loaded. for doing this I made a function then I call it anywhere:

function GraghQLAjax(params) {
    var query = JSON.stringify({
        query: `query {
            orders_month_report {
                month
                total
            }
            sales_month_report {
                month
                total_amount
            }
        }`
    });

    $.ajax({
        method: 'POST',
        url: '/graphql/',
        data: query,
        contentType: 'application/json',
        success: function (data) {
            var months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];

            // sales chart
            var sales_chart_data = [];
            $.each(data.data.sales_month_report, function (index, obj) {
                sales_chart_data.push(obj.total_amount);
            });
            SalesChart(sales_chart_data, months);

            // orders chart
            var orders_chart_data = [];
            $.each(data.data.orders_month_report, function (index, obj) {
                orders_chart_data.push(obj.total);
            });
            OrderChart(orders_chart_data, months);

        },
        error: function () {
            alert('Error occurred');
        }
    });
}

// charts function

// Line chart
function SalesChart(data, labels) {
    // Variables
    var $chart = $('#chartSales');

    var salesChart = new Chart($chart, {
        type: 'line',
        options: {
            scales: {
                yAxes: [{
                    gridLines: {
                        lineWidth: 1,
                        color: Charts.colors.gray[900],
                        zeroLineColor: Charts.colors.gray[900]
                    },
                    ticks: {
                        callback: function (value) {
                            if (!(value % 10)) {
                                return '$' + value;
                            }
                        }
                    }
                }]
            },
            tooltips: {
                callbacks: {
                    label: function (item, data) {
                        var label = data.datasets[item.datasetIndex].label || '';
                        var yLabel = item.yLabel;
                        var content = '';

                        if (data.datasets.length > 1) {
                            content += '<span class="popover-body-label mr-auto">' + label + '</span>';
                        }

                        content += '<span class="popover-body-value">$' + yLabel + '</span>';
                        return content;
                    }
                }
            }
        },
        data: {
            labels: labels,
            datasets: [{
                label: 'Performance',
                data: data
            }]
        }
    });

    // Save to jQuery object
    $chart.data('chart', salesChart);
}

// Bar chart
function OrderChart(data, labels) {
    var $chart = $('#chartOrders');

    var ordersChart = new Chart($chart, {
        type: 'bar',
        options: {
            scales: {
                yAxes: [{
                    gridLines: {
                        lineWidth: 1,
                        color: '#dfe2e6',
                        zeroLineColor: '#dfe2e6'
                    },
                    ticks: {
                        callback: function (value) {
                            if (!(value % 10)) {
                                //return '$' + value + 'k'
                                return value
                            }
                        }
                    }
                }]
            },
            tooltips: {
                callbacks: {
                    label: function (item, data) {
                        var label = data.datasets[item.datasetIndex].label || '';
                        var yLabel = item.yLabel;
                        var content = '';

                        if (data.datasets.length > 1) {
                            content += '<span class="popover-body-label mr-auto">' + label + '</span>';
                        }

                        content += '<span class="popover-body-value">' + yLabel + '</span>';

                        return content;
                    }
                }
            }
        },
        data: {
            labels: labels,
            datasets: [{
                label: 'Sales',
                data: data
            }]
        }
    });

    // Save to jQuery object
    $chart.data('chart', ordersChart);
}

Now call GraghQLAjax function whatever you want. In this example, after fetching data from GraphQL, the required params sent to the related function to show the data on charts.

DataTables (paginated information)

In this section, you can search, edit and delete the transactions. The added features of this datatable are:

• Paginated information (transaction page) with usable controls: PREV, 1,2,3., NEXT
• Search box to filter
• Delete row control
• edit cel data on double click and ENTER on confirm.

Database/table structure

Create the Transaction model to show data in the datatable:

from django.db import models

class Transaction(models.Model):
    bill_for = models.CharField(max_length=100)
    issue_date = models.DateField()
    due_date = models.DateField()
    total = models.DecimalField(max_digits=10, decimal_places=2)

    status = models.CharField(max_length=10)

    created_time = models.DateTimeField(auto_now_add=True)
    updated_time = models.DateTimeField(auto_now=True)

    class Meta:
        verbose_name = 'transaction'
        verbose_name_plural = 'transactions'

How to add data

In Django admin, you can import data for the Transaction sections. To do this just click on IMPORT button in each section, then select your csv, xls or etc file and submit it.

Download Transactions Sample data

Files (that implements the feature)

• In this section, create a view in view.py to implement CRUD (Create, Read, Update, Delete):

from django.views import View

class TransactionView(View):
    def get(self, request):
        pass

    def post(self, request):
        pass

    def put(self, request):
        pass

    def delete(self, request):
        pass

We use get to display items and forms, post to store a new item, put to update an item, and delete to remove an item.

• jQuery (AJAX) has been used to make changes in the datatable. Which is located in the app_js.js.

Social Login

Requirements

There is a convenient package to an integrated set of Django applications addressing authentication, registration, account management as well as 3rd party (social) account authentication that is very easy to use. The package is django-allauth‍ and you can read its doc to use it. and also recommend a youtube video for easier implementation.

Files (that implements the feature)

In this section, we selected Google and Github to implement.

• Added buttons in login.html and register.html.

Unitary Tests

• REST APIs test:

$ python manage.py test app.tests.RESTAPIsTest

• GraphQL test:

$ python manage.py test app.tests.GraphQLAPIsTest
