I am trying to serve a static html file, but returns a 500 error
(a copy of editor.html is on .py and templates directory)
This is all I have tried:
from flask import Flask
app = Flask(__name__, static_url_path='/templates')
#return 'Hello World1!' #this works correctly!
#return render_template(url_for('templates', filename='editor.html'))
#return app.send_static_file('editor.html') #404 error (Not Found)
return send_from_directory('templates', 'editor.html')
Title: 500 Internal Server Srror
Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.
Reducing this to the simplest method that'll work:
/static/to verify the file works
If you then still want to reuse a static file, use
current_app.send_static_file(), and do not use leading
from flask import Flask, current_app app = Flask(__name__) @app.route('/') def hello_world(): return current_app.send_static_file('editor.html')
This looks for the file
editor.html directly inside the
This presumes that you saved the above file in a folder that has a
static subfolder with a file
editor.html inside that subfolder.
Some further notes:
static_url_pathchanges the URL static files are available at, not the location on the filesystem used to load the data from.
render_template()assumes your file is a Jinja2 template; if it is really just a static file then that is overkill and can lead to errors if there is actual executable syntax in that file that has errors or is missing context.
