Right Answer:
To create APIs in Django, you can use Django REST Framework (DRF). Here are the steps:
1. **Install Django REST Framework**:
```bash
pip install djangorestframework
```
2. **Add 'rest_framework' to your `INSTALLED_APPS` in `settings.py`**:
```python
INSTALLED_APPS = [
...
'rest_framework',
]
```
3. **Create a Django model** (if you don't have one):
```python
from django.db import models
class Item(models.Model):
name = models.CharField(max_length=100)
description = models.TextField()
```
4. **Create a serializer for the model**:
```python
from rest_framework import serializers
class ItemSerializer(serializers.ModelSerializer):
class Meta:
model = Item
fields = '__all__'
```
5. **Create views for

Ques:- What is MVT and MVC, and how is it related to Django?
Asked In :-
Trigent Software, Infiniti Software Solutions, AppSquadz, Addverb Technologies, EvolveWare, Paktolus, Perceptive Analytics, Gibots, Vofox Solutions, WDS,
Right Answer:
MVT stands for Model-View-Template, and MVC stands for Model-View-Controller. In Django, MVT is a variation of MVC where:
– Model: Represents the data and business logic.
– View: Handles the logic and interacts with the model to retrieve data.
– Template: Manages the presentation layer, rendering the data to the user.
Django uses MVT to separate concerns, similar to how MVC organizes code, but with a focus on templates for rendering HTML.
Ques:- What is rate limiting in APIs and how is it implemented
Asked In :-
Vinove Software & Services Pvt Ltd, Object Frontier Software, Hidden Brains InfoTech, Netaxis IT Solutions (p), Rock Solid Solutions, Shipco IT, Walkover Web Solutions, Solace Infotech, Infinity Labs LLP, TNQ Technologies,
Right Answer:
Rate limiting in APIs is a technique used to control the number of requests a user can make to an API within a specific time period. It is implemented by setting thresholds (e.g., requests per minute) and using mechanisms like tokens, counters, or IP address tracking to monitor and restrict access when the limit is exceeded.

Ques:- What is API documentation and why is it necessary
Asked In :-
Vinove Software & Services Pvt Ltd, KRIOS Info Solutions, Queppelin Technology Solutions, Codiant Software Technologies, Born Commerce, Dhruvsoft Services, Oodles Technologies, CakeSoft Technologies, Webvillee Technology, Recodem,
Right Answer:
API documentation is a technical manual that explains how to use an API, including its endpoints, request and response formats, authentication methods, and examples. It is necessary because it helps developers understand how to integrate and interact with the API effectively, ensuring proper usage and reducing errors.
