Troubleshooting Flask TemplateNotFound Error
Despite having a home.html file in your project, you may encounter a jinja2.exceptions.TemplateNotFound error when trying to render the template with Flask. This error indicates that Flask is unable to locate the template.
To resolve this issue, ensure that you have placed your template file in the appropriate location:
-
In the templates subdirectory:
myproject/ app.py templates/ home.html
-
In the package if your app is a package:
myproject/ mypackage/ __init__.py templates/ home.html
If you have placed your template file in a non-standard location, you can specify it using:
app = Flask(__name__, template_folder='template') # still relative to module
To debug the template search path, set EXPLAIN_TEMPLATE_LOADING to True:
app = Flask(__name__, template_folder='template', explain_template_loading=True)
This will provide detailed information about the template search process in your Flask app's logs.
For blueprints, they can register their own template directories, but the main app template directory is always searched first.
The above is the detailed content of Why is Flask Throwing a TemplateNotFound Error Even Though My home.html Exists?. For more information, please follow other related articles on the PHP Chinese website!
