Flask: current page in request variable
Using request.path doesn't seem to be a proper approach since you'll have to update the paths in case of changing URL rules or deploying your site under a subfolder.
Use request.url_rule.endpoint instead, it contains actual endpoint name independent of actual path:
(Pdb) request.url_rule.endpoint'myblueprint.client_pipeline'In a template:
<li {% if request.url_rule.endpoint == "myblueprint.client_pipeline" %}class="active"{% endif %}>Home</li>Good luck!
