User roles and permissions in No-Code - Mini Project: Build & Apply

User Roles and Permissions

📖 Scenario: You are managing a small online community. You want to organize users by their roles and decide what each role can do.

🎯 Goal: Create a simple structure that lists users with their roles, define what each role can do, and then assign permissions based on roles.

📋 What You'll Learn

Create a list of users with their assigned roles

Define a dictionary of roles with their permissions

Match users to their permissions using their roles

Show the final list of users with their permissions

💡 Why This Matters

🌍 Real World

Managing user access in websites, apps, or online communities to control what actions users can perform.

💼 Career

Understanding roles and permissions is essential for jobs in IT, software development, and system administration to keep systems secure and organized.

1

Create the list of users with roles

Create a list called users with these exact entries: {'name': 'Alice', 'role': 'admin'}, {'name': 'Bob', 'role': 'editor'}, and {'name': 'Charlie', 'role': 'viewer'}.

No-Code

# Create the list of users with their roles
# Your code here

Need a hint?

Use a list of dictionaries where each dictionary has keys 'name' and 'role'.

2

Define roles with permissions

Create a dictionary called roles with these exact entries: 'admin': ['add', 'edit', 'delete'], 'editor': ['add', 'edit'], and 'viewer': ['view'].

No-Code

users = [
    {'name': 'Alice', 'role': 'admin'},
    {'name': 'Bob', 'role': 'editor'},
    {'name': 'Charlie', 'role': 'viewer'}
]
# Create the roles dictionary with permissions
# Your code here

Need a hint?

Use a dictionary where keys are role names and values are lists of permissions.

3

Assign permissions to users based on roles

Create a new list called users_with_permissions that contains dictionaries for each user with keys 'name' and 'permissions'. Use a for loop with variables user to go through users and assign permissions from roles[user['role']].

No-Code

users = [
    {'name': 'Alice', 'role': 'admin'},
    {'name': 'Bob', 'role': 'editor'},
    {'name': 'Charlie', 'role': 'viewer'}
]
roles = {
    'admin': ['add', 'edit', 'delete'],
    'editor': ['add', 'edit'],
    'viewer': ['view']
}
# Create users_with_permissions list using a for loop
# Your code here

Need a hint?

Use a loop to create a new list where each user has their permissions from the roles dictionary.

4

Complete the user permissions structure

Add a final line that creates a variable called final_structure and assigns it the value of users_with_permissions.

No-Code

users = [
    {'name': 'Alice', 'role': 'admin'},
    {'name': 'Bob', 'role': 'editor'},
    {'name': 'Charlie', 'role': 'viewer'}
]
roles = {
    'admin': ['add', 'edit', 'delete'],
    'editor': ['add', 'edit'],
    'viewer': ['view']
}
users_with_permissions = []
for user in users:
    users_with_permissions.append({'name': user['name'], 'permissions': roles[user['role']]})
# Assign final_structure to users_with_permissions
# Your code here

Need a hint?

Just assign the list with permissions to a new variable for clarity.
