Product Development Hiring Project

As part for a Product Development Hiring Project for BriteCore. This is a solution for the problem where the data model is pretty rigid. This solution is focus to insurers can define their own custom data model for their risk.

Backend

For Backend I used Django and Django REST framework with two models:

class Risk(models.Model):
    name = models.CharField(max_length=100)
    description = models.CharField(max_length=500, blank=True)

    def __str__(self):
        return self.name


class Field(models.Model):
    TYPE_CHOICES = (
        ('text', 'Text'),
        ('date', 'Date'),
        ('number', 'Number'),
    )
    name = models.CharField(max_length=100)
    type = models.CharField(max_length=10, choices=TYPE_CHOICES,
                            default='text')
    label = models.CharField(max_length=100)
    risk = models.ForeignKey(Risk, on_delete=models.CASCADE)

    def __str__(self):
        return self.name

Creating risks and fields

from risk.models import Risk, Field

Risk.objects.create(
    name='automobile', 
    description='Risk for automobile insurance')

automobile = Risk.objects.create(
    name='automobile',
    description='Risk for automobile insurance')

Field.objects.create(
    name='chassis',
    type='text',
    label='Chassis',
    risk=automobile)    

Field.objects.create(
    name='color',
    type='text',
    label='Color',
    risk=automobile)    

Field.objects.create(
    name='purchase_date',
    type='date',
    label='Purchase date',
    risk=automobile)            

Field.objects.create(
    name='commercial_value',
    type='number',
    label='Commercial value',
    risk=automobile)    

person = Risk.objects.create(
    name='person',
    description='Risk for life insurance')

Field.objects.create(
    name='first_name',
    type='text',
    label='First name',
    risk=person) 

Field.objects.create(
    name='last_name',
    type='text',
    label='Last name',
    risk=person) 

Field.objects.create(
    name='birth_date',
    type='date',
    label='Birth date',
    risk=person)     

Frontend

For Frontend I used Vue.js and Boostrap

Running the tests

You can run the unit tests using the following command

python manage.py test

Deployment

For Frontend I used Zappa

$ pip install zappa
$ zappa init
$ zappa deploy dev
Deploying..
Your application is now live at: https://itqbut4z6g.execute-api.us-east-1.amazonaws.com/dev/

Next you have to modify settings.py with credentials and host of AWS, then you can update your deploy:

$ zappa update dev

Built With

• Django - python Web framework
