from flask import Flask, redirect, url_for, request | |
app = Flask(__name__) | |
is_maintenance_mode = True | |
# Always throw a 503 during maintenance: http://is.gd/DksGDm | |
@app.before_request | |
def check_for_maintenance(): | |
if is_maintenance_mode and request.path != url_for('maintenance'): | |
return redirect(url_for('maintenance')) | |
# Or alternatively, dont redirect | |
# return 'Sorry, off for maintenance!', 503 | |
@app.route('/') | |
def index(): | |
return 'Hello!' | |
@app.route('/maintenance') | |
def maintenance(): | |
return 'Sorry, off for maintenance!', 503 | |
if __name__ == '__main__': | |
app.run() |
Better solution IMHO:
from flask import Flask, abort
import os
app = Flask(__name__)
@app.before_request
def check_under_maintenance():
if os.path.exists("maintenance"): # Check if a "maintenance" file exists (whatever it is empty or not)
abort(503) # No need to worry about the current URL, redirection, etc
@app.route('/')
def index():
return "This is Admiral Ackbar, over"
@app.errorhandler(503)
def error_503(error):
return "It's a trap!", 503
if __name__ == '__main__':
app.run()
@app.before_request
def check_for_maintenance():
rule = request.url_rule.rule
if is_maintenance_mode and 'maintenance' not in rule:
return redirect(url_for('maintenance'))
Also works

Nice solution!, thanks :)
"if is_maintenance_mode and request.path != url_for('maintenance') and not 'static' in request.path "
With that, the site still showing all the styles and does not show the site as plain text
Best regards and thanks again
