Re: Filtering fields in http response data from http request url ?

[Sam Chaffy]

Using django rest framework, create a serializer class and specify the
right field you want to display at the end.

Please check this link

https://www.django-rest-framework.org/api-guide/serializers/

Re: unable Integrating Djongo 1.3.1 with django 2.2.10

[Sam Chaffy]

Install pymongo package by > pip install pymongo


or, better practice

make a virtual environment directory where all your dependencies will be 
installed.


> python -m venv  myvenv (assuming you name it myvenv)

If you are in Windows 

activate virtual environment with:

> cd in directory where you created virtual environment

> myvenv\Scripts\activate

Make sure you have pip installed

> pip install pymongo

then you won't have this error.
