What happens when you run 'python manage.py runserver' inside a Django project?

Select the correct description of what the command python manage.py runserver does inside a Django project directory.

A Compiles Django templates into static HTML files.

B Starts a local web server to serve the Django application for development.

C Creates a new Django app inside the project.

D Deploys the Django project to a live production server.

💡 Hint

Think about what you need to do to see your Django site in a browser during development.

The 'runserver' command launches a lightweight web server on your local machine to test your Django app during development. It does not create apps, compile templates, or deploy to production.

🔧 Debug

Why does this command fail? django-admin startproject myproject .

You run the command django-admin startproject myproject . inside an existing directory but get an error. What is the most likely cause?

A The current directory is not empty, so Django refuses to create the project here.

B The dot (.) at the end is invalid syntax for this command.

C You must run the command outside any directory to create a project.

D The project name cannot be 'myproject' because it conflicts with a Python module.

💡 Hint

Django expects an empty directory or a new directory for the project files.

When you use a dot (.) to create the project in the current directory, Django requires that directory to be empty. If it contains files, the command fails to avoid overwriting.

❓ state_output

After creating a Django project, what files are generated inside the project directory?

You run django-admin startproject mysite. Which of the following lists the files and folders you will find inside the mysite directory?

A An apps folder with all Django apps pre-created

B Only a manage.py file and a templates folder

C A single mysite.py file with all settings and URLs

D manage.py file and a subdirectory named mysite containing __init__.py, settings.py, urls.py, and wsgi.py

💡 Hint

Think about the default structure Django creates for a new project.

Django creates a manage.py file at the root and a subdirectory named after the project containing core files like settings.py and urls.py.

🧠 Conceptual

What is the purpose of the 'manage.py' file in a Django project?

Choose the best explanation of what the manage.py file does in a Django project.

A It is a command-line utility that lets you interact with the Django project for tasks like running the server and migrations.

B It compiles static files like CSS and JavaScript for deployment.

C It stores the database configuration and credentials.

D It contains the main application logic and routes HTTP requests.

💡 Hint

Think about how you run commands like 'runserver' or 'migrate' in Django.

The manage.py file is a script that wraps Django commands to manage the project, such as starting the server, applying migrations, and creating apps.

1. What is the correct command to create a new Django project named mywebsite?

easy

A. django-admin startproject mywebsite

B. django startproject mywebsite

1. Step 1: Understand the Django project creation command

   The official command to create a new Django project is django-admin startproject projectname.

2. Step 2: Match the command with the project name

   Replacing projectname with mywebsite gives django-admin startproject mywebsite.

3. Final Answer:

   django-admin startproject mywebsite -> Option A

4. Quick Check:

   Correct command = django-admin startproject mywebsite [OK]

Hint: Use 'django-admin startproject' plus your project name [OK]

Common Mistakes:

• Using 'django startproject' instead of 'django-admin startproject'
• Using 'createproject' or 'newproject' which are invalid commands
• Forgetting to specify the project name

A. django-admin startproject blog

B. django-admin start project blog

C. django-admin startprojectblog

D. django-admin create project blog

2. Step 2: Identify the correct option

   django-admin startproject blog matches the correct syntax exactly: django-admin startproject blog.

3. Final Answer:

   django-admin startproject blog -> Option A

4. Quick Check:

3. After running django-admin startproject testsite, which folder structure will be created?

medium

A. A folder named testsite with only one file settings.py

B. A folder named testsite containing only manage.py file

C. A folder named testsite containing manage.py and urls.py only

D. A folder named testsite containing manage.py and a subfolder testsite with settings files

Solution

1. Step 1: Recall Django project folder structure

   Running django-admin startproject testsite creates a folder testsite with manage.py and a subfolder testsite containing settings.py, urls.py, asgi.py, and wsgi.py.

2. Step 2: Match the correct folder structure

   A folder named testsite containing manage.py and a subfolder testsite with settings files correctly describes this structure with manage.py and a subfolder testsite holding settings files.

3. Final Answer:

   Folder with manage.py and subfolder testsite with settings files -> Option D

4. Quick Check:

   Default Django project structure = A folder named testsite containing manage.py and a subfolder testsite with settings files [OK]

Hint: Remember: project folder has manage.py plus inner folder with settings [OK]

Common Mistakes:

• Expecting all files in one folder without subfolder
• Thinking only manage.py is created
• Confusing project folder and app folder structure

3. Final Answer:

   Django is not installed or not in your system PATH -> Option C

4. Quick Check:

   Command not found = Django missing or PATH issue [OK]

Hint: Check Django installation and PATH if 'command not found' error appears [OK]

Common Mistakes:

• Assuming project name typo causes command not found
• Trying to run command inside project folder before creating it
• Using wrong command syntax instead of fixing PATH

2. Step 2: Choose the correct folder navigation

   To create shop inside websites, first go into websites folder, then run django-admin startproject shop.

3. Final Answer:

   Navigate to websites folder, then run django-admin startproject shop -> Option B
