Flask route handler that renders and displays the user guide page for the application.

File:
/tf/active/vicechatdev/docchat/app.py
Lines:
824 - 826
Complexity:
simple

Purpose

This function serves as a web endpoint to display the user guide documentation to authenticated users. It is protected by the login_required decorator, ensuring only authenticated users can access the guide. The function simply renders the 'user_guide.html' template without any dynamic data processing.

Source Code

def user_guide():
    """User guide page"""
    return render_template('user_guide.html')

Return Value

Returns a rendered HTML template (user_guide.html) as a Flask Response object. The template is rendered using Flask's render_template function and contains the user guide documentation content.

Dependencies

  • flask

Required Imports

from flask import render_template

Usage Example

from flask import Flask, render_template
from functools import wraps

app = Flask(__name__)

# Example login_required decorator (simplified)
def login_required(f):
    @wraps(f)
    def decorated_function(*args, **kwargs):
        # Check if user is authenticated
        if not session.get('user_id'):
            return redirect(url_for('login'))
        return f(*args, **kwargs)
    return decorated_function

@app.route('/user-guide')
@login_required
def user_guide():
    """User guide page"""
    return render_template('user_guide.html')

if __name__ == '__main__':
    app.run(debug=True)

Best Practices

  • Ensure the 'user_guide.html' template exists in the templates directory before deploying
  • The login_required decorator should be placed after the route decorator to ensure proper authentication checking
  • Consider adding error handling for missing template files in production environments
  • The template should be designed to be responsive and accessible to all users
  • Consider adding caching headers for static documentation content to improve performance
  • If the user guide content is extensive, consider implementing pagination or a table of contents
  • Ensure the authentication system properly handles session management and redirects unauthenticated users
