data_store['key'] = 'value'

# To retrieve data
value = data_store.get('key')
```

Python Django

Ques:- How to get all logged-in user list or count

Asked In :- TetraSoft, Tecnotree, Deep Compute, Enbraun, Centillion Networks, transunion, zaloni, open source, incorta, zendrive,

Right Answer:
To get the count of all logged-in users in Django, you can use the `Session` model to filter sessions that are currently active. Here's a simple way to do it:

```python
from django.contrib.sessions.models import Session
from django.utils import timezone

# Get all active sessions
active_sessions = Session.objects.filter(expire_date__gte=timezone.now())

# Count of logged-in users
logged_in_user_count = active_sessions.count()
```

To get a list of logged-in users, you can extract the user IDs from the sessions:

```python
logged_in_users = [session.get_decoded().get('_auth_user_id') for session in active_sessions]
```

Python Django

Ques:- what is signals and how to use it? What are two important parameter in signals?

Asked In :- Klick Health, Net-Square Solutions, ATOS Syntel, speridian technologies, comparethemarket.com, appnovation technologies, lera technologies, monocept, cubet techno labs, wissen technology,

Right Answer:
In Django, signals are a way to allow certain senders to notify a set of receivers when some action has taken place. They are used to decouple applications by allowing different parts of an application to communicate without being tightly coupled.

To use signals, you typically connect a receiver function to a signal using the `@receiver` decorator or the `connect()` method.

Two important parameters in signals are:
1. `sender`: The model class that sends the signal.
2. `instance`: The actual instance of the model that triggered the signal.

Python Django

Ques:- Django group_by query

Asked In :- FUTURISM TECHNOLOGIES PVT, AppItSimple Infotek Pvt Lmt, Talencia LLC, JustDial, ColorTokens, Thryve Digital, MRI Software, Akasa Labs, Casa Systems, KPIT Technologies,

Right Answer:
In Django, you can use the `annotate()` and `values()` methods to perform a group by query. Here's an example:

```python
from django.db.models import Count
from your_app.models import YourModel

result = YourModel.objects.values('field_to_group_by').annotate(count=Count('id'))
```

This will group the records by `field_to_group_by` and count the number of occurrences for each group.

Python Django

Ques:- how you will write django complex query?

Asked In :- Incise Infotech, Propel, Visteon, Tagit Pte, ION Group, Embibe, TP1, Anova Data, CodeQuotient, Softserve Global,

Right Answer:
To write a complex query in Django, you can use the `Q` objects for complex lookups and chaining filters. For example:

```python
from django.db.models import Q
from myapp.models import MyModel

# Example of a complex query
results = MyModel.objects.filter(
Q(field1__icontains='value1') | Q(field2__gte=10)
).exclude(field3='value2').order_by('-field4')
```

This query filters `MyModel` instances where `field1` contains 'value1' or `field2` is greater than or equal to 10, excludes those with `field3` equal to 'value2', and orders the results by `field4` in descending order.

Python Django

Ques:- how you used session ? How can we handle session expire time ?

Asked In :- Recodem, Ascentx Software Development Services, Kyro, Data Patterns, ACS IT SOLUTIONS, Algorithmic Trading Strategies Pty, C-Edge Technologies, Ergo Group, The Daffodil, SSB Software Solutions,

Right Answer:
In Django, you can use sessions by accessing the `request.session` dictionary to store and retrieve data. To handle session expiration time, you can set the `SESSION_COOKIE_AGE` setting in your `settings.py` file, which defines the duration (in seconds) before a session expires. For example, to set a session to expire after 30 minutes, you would use:

```python
SESSION_COOKIE_AGE = 1800 # 30 minutes
```

Python Django

Ques:- what are all middleware you used and whats the purpose ot it?

Asked In :- rapidera technologies, Girmiti Software, Gainers Infotech, RTRT, NAB - National Australia Bank, PromptCloud, MindNerves Technologies, Valuefy Solutions, Able Design Engineering Services, infiniX (India),

Right Answer:
Some common middleware used in Django include:

1. **SecurityMiddleware**: Adds security-related headers to responses.
2. **SessionMiddleware**: Manages user sessions across requests.
3. **AuthenticationMiddleware**: Associates users with requests, enabling user authentication.
4. **MessageMiddleware**: Enables temporary message storage for user notifications.
5. **CommonMiddleware**: Provides various utilities, such as URL normalization and handling of empty GET/POST data.
6. **CsrfViewMiddleware**: Protects against Cross-Site Request Forgery attacks by adding CSRF tokens.

Each middleware serves a specific purpose in processing requests and responses in a Django application.

Python Django

Ques:- how you will add extra function/feature in admin part

Asked In :- Pennant Technologies, Kcloud Technologies, iauro systems, eBay Classifieds, Aptus Data Labs, Telesoft Labs, QualiTLabs, OX SoftwareS, Vantage Systech, Smart Sight Innovations,

Right Answer:
To add an extra function or feature in the Django admin, you can override the `ModelAdmin` class for your model. You can define custom methods and add them as actions, or you can customize the admin form by using `form` attribute in your `ModelAdmin`. Additionally, you can use `list_display`, `search_fields`, and `list_filter` to enhance the admin interface. Finally, register your model with the customized `ModelAdmin` class using `admin.site.register()`.

Python Django

Ques:- What is the use of manage.py

Asked In :- Technonix Infosystem, rapidera technologies, Ginni Systems, Jeevan Technologies, LAP, NRSC National Remote Sensing Centre, TMR, Streebo Solutions, Cloud Analogy, Peocit,

Right Answer:
`manage.py` is a command-line utility in Django that allows you to interact with your Django project. It helps you run server commands, manage database migrations, create applications, and perform various administrative tasks.

Python Django

Ques:- what is __init__.py inisde application folder?

Asked In :- Innominds Software (P), Mundrisoft Solutions LLP, Falcon Autotech, Nuware Systems, Dassault Systemes, Posist Technologies, CloudKaptan, SpeedLabs, Winjit Technologies, copart,

Right Answer:
`__init__.py` is a special Python file that indicates to Python that the directory it is in should be treated as a package. In a Django application folder, it allows the application to be recognized as a module, enabling the import of its components.

Python Django

Ques:- How django works (work flow)

Asked In :- iROID Technologies, Talent Smart Soft Solutions (OPC), Aptroid, Amiti Software Technologies, FACTENTRY DATA SOLUTIONS, ApMoSys Technologies, Atypon Systems, AcuityAds, Intello Labs, Cittabase Solutions,

Right Answer:
Django works through the following workflow:

1. **Request**: A user makes a request to the Django server via a URL.
2. **URL Routing**: Django uses the URL dispatcher to match the request URL to a specific view function.
3. **View Processing**: The matched view function processes the request, interacts with the database if needed, and prepares a response.
4. **Template Rendering**: If the view returns HTML, Django uses templates to render the final HTML response.
5. **Response**: Django sends the generated response back to the user's browser.

This cycle continues for each request made to the server.

Python Django

Ques:- Explain the architecture of Django?

Asked In :- Siam Computing, Tecnotree, BluePi, Access Research, epam systems, one advanced, first derivatives, capillary technologies, confirmit, wheels up,

Right Answer:
Django follows the Model-View-Template (MVT) architecture:

1. **Model**: Defines the data structure and interacts with the database. It represents the data layer of the application.
2. **View**: Contains the business logic and handles user requests. It retrieves data from the model and passes it to the template.
3. **Template**: Manages the presentation layer. It defines how the data is displayed to the user.

Django also includes a URL dispatcher that maps URLs to views, and it follows the "Don't Repeat Yourself" (DRY) principle to promote code reusability.

Python Django

Asked In :- Hidden Brains InfoTech, Spark Infosys, Sify Technologies, Rightpoint India Digital, Bristlecone India, Scadea Solutions, Gaian Solutions India, NoBroker, Celebal, Audax Labs,

Right Answer:
Django is a high-level Python web framework that simplifies the development of web applications by providing built-in features such as an ORM (Object-Relational Mapping), an admin interface, and tools for handling user authentication, URL routing, and form processing. It follows the MVC (Model-View-Controller) architectural pattern and promotes rapid development and clean, pragmatic design.
