Creating a To-Do List App with Django, DRF, Alpine.JS And Axios

Introduction

To-do List is a pretty basic example app that is often done as one of the first projects, today we will make it a little more interesting by using few interesting technologies.

As the backend we will use Django and Django Rest Framework, and Alpine.js + Axios to glue it all together easily on the frontend.

What is Alpine.js

A pretty new lightwave framework inspired by Vue.js created last year by Caleb Porzio it gives us reactivity and declarativity of React and Vue, while keeping it light, and in the DOM. It’s described as TailwindCSS for JS. And I pretty much agree with that, using it together with Tailwind is a great boost to productivity when doing front-end because you can stay in one HTML file, and keep writing HTML, CSS, and js.

Axios

It’s an asynchronous HTTP client for JS.

Here is a link to finished project GitHub repo

Starting the app

Let’s start by creating a new virtual environment for our project, and installing required packages, then create a new Django project, and a lists app

pip install Django 
pip install djangorestframework
django-adimn startproject todo_list
cd todo_list
django-admin startapp lists

Then go to settings.py and add lists and django rest framework app to INSTALLED_APPS

INSTALLED_APPS = [
    ...
    ‘rest_framework’,
    ‘lists’,
]

Creating App Models

Let’s create db models for our To-Do App. We are going to define 2 models, a List Model, and a Task model, Each user can create as many lists as he/she wants, and then add multiple tasks to each list.

from django.contrib.auth.models import User
from django.db import models

class List(models.Model):
    title = models.CharField(max_length=75)
    user = models.ForeignKey(User,
                             on_delete=models.CASCADE,
                             related_name=‘lists’)
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)

class Task(models.Model):
    parent_list = models.ForeignKey(List,
                                    on_delete=models.CASCADE,
                                    related_name=‘tasks’)
    title = models.CharField(max_length=75)
    completed = models.BooleanField(default=False, 
                                    blank=True)
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)

We created a List model with the title field and relation to the user who created the list.

The Task model, has a relation to List object, title, and boolean for the complete status of the task.

Also for both models also 2 DateTime fields for cerated and updated times.

Go to the admin.py file and register the models in the admin panel

from django.contrib import admin

from .models import List, Task

admin.site.register(List)
admin.site.register(Task)

Run the makemigrations and migrate commands.

python manage.py makemigrations
python manage.py migrateapi

Create API

Create Serializers

Inside the lists app create a new python package (new directory with an empty __init__.py file), and call it api. There create a file serializers.py, views.py, urls.py files inside. Go to serialziers.py and create serializers for the models.

from rest_framework import serializers

from ..models import List, Task

class TaskSerializer(serializers.ModelSerializer):
    class Meta:
        model = Task
        fields = (‘title’, ‘completed’, ‘parent_list’)

class ListSerializer(serializers.ModelSerializer):
    tasks = TaskSerializer(many=True, read_only=True)

    class Meta:
        model = List
        fields = (‘title’, ‘tasks’)

Create Viewsets

Now we will create viewsets, that will automatically provide us with Create, Read, Update, and Delete endpoints (CRUD), so we can avoid repetition and writing them for each model. In views.py file create viewsets.

from rest_framework import viewsets
from rest_framework.authentication import SessionAuthentication
from rest_framework.permissions import IsAuthenticated

from .serializers import TaskSerializer, ListSerializer
from ..models import Task, List

class ListViewSet(viewsets.ModelViewSet):
    queryset = Task.objects.all()
    serializer_class = ListSerializer
    authentication_classes = [SessionAuthentication]
    permission_classes = [IsAuthenticated]

    def get_queryset(self):
        user = self.request.user
        return List.objects.filter(user=user)

        def create(self, request, *args, **kwargs):
        serializer = ListSerializer(data=request.data)
        if serializer.is_valid():
            serializer.save(user=request.user)
            return Response(serializer.validated_data, status=status.HTTP_201_CREATED)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

class TaskViewSet(viewsets.ModelViewSet):
    queryset = Task.objects.all()
    serializer_class = TaskSerializer
    authentication_classes = [SessionAuthentication]
    permission_classes = [IsAuthenticated]

    def get_queryset(self):
        user = self.request.user
        return Task.objects.filter(parent_list__user=user)

Best Electric Bikes and Scooters for Rental Business or Campus Facility

The electric scooter revolution has caught on super-fast taking many cities across the globe by storm. eScooters, a renovated version of old-school scooters now turned into electric vehicles are an environmentally friendly solution to current on-demand commute problems. They work on engines, like cars, enabling short traveling distances without hassle. The result is that these groundbreaking electric machines can now provide faster transport for less — cheaper than Uber and faster than Metro.

Since they are durable, fast, easy to operate and maintain, and are more convenient to park compared to four-wheelers, the eScooters trend has and continues to spike interest as a promising growth area. Several companies and universities are increasingly setting up shop to provide eScooter services realizing a would-be profitable business model and a ready customer base that is university students or residents in need of faster and cheap travel going about their business in school, town, and other surrounding areas.

Electric Scooters Trends and Statistics

In many countries including the U.S., Canada, Mexico, U.K., Germany, France, China, Japan, India, Brazil and Mexico and more, a growing number of eScooter users both locals and tourists can now be seen effortlessly passing lines of drivers stuck in the endless and unmoving traffic.

A recent report by McKinsey revealed that the E-Scooter industry will be worth― $200 billion to $300 billion in the United States, $100 billion to $150 billion in Europe, and $30 billion to $50 billion in China in 2030. The e-Scooter revenue model will also spike and is projected to rise by more than 20% amounting to approximately $5 billion.

And, with a necessity to move people away from high carbon prints, traffic and congestion issues brought about by car-centric transport systems in cities, more and more city planners are developing more bike/scooter lanes and adopting zero-emission plans. This is the force behind the booming electric scooter market and the numbers will only go higher and higher.

Companies that have taken advantage of the growing eScooter trend develop an appthat allows them to provide efficient eScooter services. Such an app enables them to be able to locate bike pick-up and drop points through fully integrated google maps.

List of Best Electric Bikes for Rental Business or Campus Facility 2020:

It’s clear that e scooters will increasingly become more common and the e-scooter business model will continue to grab the attention of manufacturers, investors, entrepreneurs. All this should go ahead with a quest to know what are some of the best electric bikes in the market especially for anyone who would want to get started in the electric bikes/scooters rental business.

How to start an electric scooter facility/fleet in a university campus/IT park

Are you leading an organization that has a large campus, e.g., a large university? You are probably thinking of introducing an electric scooter/bicycle fleet on the campus, and why wouldn’t you?

Introducing micro-mobility in your campus with the help of such a fleet would help the people on the campus significantly. People would save money since they don’t need to use a car for a short distance. Your campus will see a drastic reduction in congestion, moreover, its carbon footprint will reduce.

Micro-mobility is relatively new though and you would need help. You would need to select an appropriate fleet of vehicles. The people on your campus would need to find electric scooters or electric bikes for commuting, and you need to provide a solution for this.

To be more specific, you need a short-term electric bike rental app. With such an app, you will be able to easily offer micro-mobility to the people on the campus. We at Devathon have built Autorent exactly for this.

What does Autorent do and how can it help you? How does it enable you to introduce micro-mobility on your campus? We explain these in this article, however, we will touch upon a few basics first.

Micro-mobility: What it is

micro-mobility

You are probably thinking about micro-mobility relatively recently, aren’t you? A few relevant insights about it could help you to better appreciate its importance.

Micro-mobility is a new trend in transportation, and it uses vehicles that are considerably smaller than cars. Electric scooters (e-scooters) and electric bikes (e-bikes) are the most popular forms of micro-mobility, however, there are also e-unicycles and e-skateboards.

You might have already seen e-scooters, which are kick scooters that come with a motor. Thanks to its motor, an e-scooter can achieve a speed of up to 20 km/h. On the other hand, e-bikes are popular in China and Japan, and they come with a motor, and you can reach a speed of 40 km/h.

You obviously can’t use these vehicles for very long commutes, however, what if you need to travel a short distance? Even if you have a reasonable public transport facility in the city, it might not cover the route you need to take. Take the example of a large university campus. Such a campus is often at a considerable distance from the central business district of the city where it’s located. While public transport facilities may serve the central business district, they wouldn’t serve this large campus. Currently, many people drive their cars even for short distances.

As you know, that brings its own set of challenges. Vehicular traffic adds significantly to pollution, moreover, finding a parking spot can be hard in crowded urban districts.

Well, you can reduce your carbon footprint if you use an electric car. However, electric cars are still new, and many countries are still building the necessary infrastructure for them. Your large campus might not have the necessary infrastructure for them either. Presently, electric cars don’t represent a viable option in most geographies.

As a result, you need to buy and maintain a car even if your commute is short. In addition to dealing with parking problems, you need to spend significantly on your car.

All of these factors have combined to make people sit up and think seriously about cars. Many people are now seriously considering whether a car is really the best option even if they have to commute only a short distance.

This is where micro-mobility enters the picture. When you commute a short distance regularly, e-scooters or e-bikes are viable options. You limit your carbon footprints and you cut costs!

Businesses have seen this shift in thinking, and e-scooter companies like Lime and Bird have entered this field in a big way. They let you rent e-scooters by the minute. On the other hand, start-ups like Jump and Lyft have entered the e-bike market.

Think of your campus now! The people there might need to travel short distances within the campus, and e-scooters can really help them.

How micro-mobility can benefit you

benefits-micromobility

What advantages can you get from micro-mobility? Let’s take a deeper look into this question.

Micro-mobility can offer several advantages to the people on your campus, e.g.:

Affordability: Shared e-scooters are cheaper than other mass transportation options. Remember that the people on your campus will use them on a shared basis, and they will pay for their short commutes only. Well, depending on your operating model, you might even let them use shared e-scooters or e-bikes for free!
Convenience: Users don’t need to worry about finding parking spots for shared e-scooters since these are small. They can easily travel from point A to point B on your campus with the help of these e-scooters.
Environmentally sustainable: Shared e-scooters reduce the carbon footprint, moreover, they decongest the roads. Statistics from the pilot programs in cities like Portland and Denver showimpressive gains around this key aspect.
Safety: This one’s obvious, isn’t it? When people on your campus use small e-scooters or e-bikes instead of cars, the problem of overspeeding will disappear. you will see fewer accidents.
