Here are some of the choices that I made during development

• Decoupling the sensitive credentials

  • Option 1: Use os.getenv('env_name') or os.environ['env_name']
  • Option 2: Use Python decouple
  • My choice: I went with python decouple as it help in discoverability of .env files. Config can be declared in .env or .ini file and it provided inbuilt support for type casting

• Validating the data received for the front end

  • Option 1: Pass each value to the validator function and raise validation error accordingly
  • Option 2: Use Django forms respective FormField and take benefit of inbuilt validation
  • My choice: I went with using the second option as better to use Django's inbuilt form fields and take the benefits of the validation provided by them

• Using form in django template

  • Option 1: Using custom html/css to build the from

    •   <form action="." method="post">
            <label for="id_from_date">From date:</label>
      
            <input type="date" id="id_from_date" name="from_date"
                   value="2022-01-01"
                   min="2018-01-01" max="2022-12-31">
            <label for="id_to_date">To date:</label>
      
            <input type="date" id="id_to_date" name="to_date"
                   value="2022-01-31"
                   min="2018-01-01" max="2022-12-31">
            <input type="submit" value="Filter">
        </form>

  • Option 2: Using django form to render the form in html

    • <form action="." method="post">
        {% csrf_token %}
        {{form.as_p}}
        <input type="submit" value="Filter">
      </form>
          

  • My choice : I went with option 2 as it is more readable and major logic and validation can be controlled from backend.
