Right Answer: Yes, I have customized the Django admin style by using custom CSS and JavaScript files, and by overriding admin templates to change the appearance and layout of the admin interface.
Right Answer: To set up a database in Django, follow these steps:
1. **Install Database Driver**: Install the appropriate database driver for your database (e.g., `psycopg2` for PostgreSQL, `mysqlclient` for MySQL).
2. **Configure Database Settings**: In your Django project's `settings.py` file, update the `DATABASES` setting with your database configuration. For example:
```python
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql', # or 'mysql', 'sqlite3', etc.
'NAME': 'your_database_name',
'USER': 'your_username',
'PASSWORD': 'your_password',
'HOST': 'localhost', # or your database host
'PORT': '5432', # or your database port
}
}
```
3. **Run Migrations**: Execute the following command to create the necessary database tables
Right Answer: To create a project in Django, follow these steps:
1. Install Django using pip: `pip install django`.
2. Open your terminal or command prompt.
3. Navigate to the directory where you want to create the project.
4. Run the command: `django-admin startproject projectname`, replacing `projectname` with your desired project name.
5. Navigate into the project directory: `cd projectname`.
6. Run the development server with: `python manage.py runserver`.
The continue is a jump in Python which moves the control to execute the next cycle in a loop leaving all the rest of the guidelines in the block unexecuted.
Right Answer: API versioning is the practice of managing changes to an API by assigning version numbers to different iterations of the API. It is important because it allows developers to introduce new features or make changes without breaking existing client applications that rely on older versions, ensuring backward compatibility and a smoother transition for users.
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.
Right Answer: The common status codes in HTTP responses are:
- **200**: OK
- **201**: Created
- **204**: No Content
- **400**: Bad Request
- **401**: Unauthorized
- **403**: Forbidden
- **404**: Not Found
- **500**: Internal Server Error
- **502**: Bad Gateway
- **503**: Service Unavailable
Right Answer: JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. In APIs, JSON is commonly used to format data exchanged between a client and a server, allowing for structured data representation in requests and responses.
Right Answer: An API Gateway acts as a single entry point for clients to access multiple microservices, handling requests, routing them to the appropriate services, managing authentication, rate limiting, and aggregating responses.
Right Answer: Cross-functional teams in Agile are important because they bring together all the necessary skills to complete work without dependencies on other teams. This leads to faster delivery, better problem-solving, and increased innovation. To foster collaboration, encourage open communication, shared understanding of goals, mutual respect, and a focus on collective ownership.
* **Individuals and interactions** over processes and tools.
* **Working software** over comprehensive documentation.
* **Customer collaboration** over contract negotiation.
* **Responding to change** over following a plan.

Right Answer: Scrum is an Agile framework for managing and completing complex projects.
Implementation involves:
1. **Roles:** Defining roles like Product Owner, Scrum Master, and Development Team.
2. **Sprints:** Working in short, time-boxed iterations (Sprints), typically 2-4 weeks.
3. **Artifacts:** Using artifacts like Product Backlog, Sprint Backlog, and Increment.
4. **Events:** Conducting events such as Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective.
5. **Continuous Improvement:** Regularly inspecting and adapting the process based on feedback.
Right Answer: Agile ceremonies are recurring meetings within a sprint to facilitate communication, planning, and continuous improvement.
* **Sprint Planning:** The team decides what work to complete in the upcoming sprint. They discuss user stories, estimate effort, and define the sprint goal.
* **Daily Stand-up:** A brief daily meeting where the team shares progress, identifies roadblocks, and coordinates efforts. Each member typically answers: What did I do yesterday? What will I do today? Are there any impediments?
* **Sprint Review:** The team demonstrates the completed work to stakeholders, gathering feedback and ensuring alignment with expectations.
* **Sprint Retrospective:** The team reflects on the past sprint, identifying what went well, what could be improved, and defining action items to enhance future performance.
Right Answer: The Scrum Master is a servant-leader who helps the Scrum Team follow the Scrum framework. They facilitate Scrum events (Sprint Planning, Daily Scrum, Sprint Review, Sprint Retrospective), remove impediments, protect the team from distractions, and coach the team on Agile principles and practices.
