Flask route handler that renders the user guide page for the document chat application.

Purpose

This function serves as a Flask view endpoint that displays the user guide documentation page to authenticated users. It is part of the docchat blueprint and requires user authentication via the login_required decorator. The function simply renders a static template containing user documentation and instructions for using the document chat system.

Source Code

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

Return Value

Returns a rendered HTML template (flask.Response object) containing the user guide page content from 'docchat/user_guide.html'. This is a standard Flask template response that will be sent to the client's browser.

Dependencies

• flask
• flask_login

Required Imports

from flask import render_template
from flask_login import login_required

Usage Example

from flask import Flask, render_template
from flask_login import login_required, LoginManager

app = Flask(__name__)
app.secret_key = 'your-secret-key'
login_manager = LoginManager()
login_manager.init_app(app)

# Register blueprint
from your_module import docchat_bp
app.register_blueprint(docchat_bp, url_prefix='/docchat')

# The route will be accessible at /docchat/user-guide
# Users must be authenticated to access this page
# When accessed, it renders the user_guide.html template

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

Best Practices

• Ensure the template file 'docchat/user_guide.html' exists in the Flask templates directory before deploying
• The login_required decorator must be applied after the route decorator to ensure proper authentication checking
• Consider adding error handling if the template file might be missing
• This function follows the Flask convention of returning rendered templates for GET requests
• The route is part of a blueprint (docchat_bp), so ensure the blueprint is properly registered with the Flask app
• Consider adding caching headers for this static content page to improve performance
