So far the website I created, there is no error handling. First of all, I implemented 404 page, which is used in case there is no page(or files) found for the requested directory.
Output Example:
– Default 404 page … This page does serve the what it’s supposed to (to inform the user there is no file found), but I like it to be more unique.
– Customized 404 page … I pasted a image so that it looks more distinctive. At this moment, it’s not responsive at all, and the image size is fixed.
Here is the changes I made (for full history you can check my github repository):
– This is 404 page html template.
{% extends "base.html" %}
{% block content %}
<h1>File Not Found</h1>
<img src="https://s3.amazonaws.com/your-bucket/your-404-image.jpg" alt="404 image"/>
<p><a href="{{ url_for('index') }}">Back</a></p>
{% endblock %}– This is error handling module. I used separate module rather than using existing routes module.
from flask import render_template
from app import app
@app.errorhandler(404)
def not_found_error(error):
return render_template('404.html'), 404– This is init file to include newly created error routing.
from flask import Flask from config import Config app = Flask(__name__) app.config.from_object(Config) from app import routes, errors
