Ignoring endpoints, Frozen-Flask MissingURLGeneratorWarning?

Question

Previous question about choosing only specific files to freeze.

I have been working on trying to get Frozen-Flask that I want to ignore certain endpoints to keep those URLs dynamic and not static in this app. Is there a way to make a list of endpoints for Frozen-Flask to ignore.

#imports
app = Flask(__name__)
freezer = Freezer(with_no_argument_rules = False, log_url_for = False, app = app)
app.config['FREEZER_DESTINATION'] = 'build'

#app-bluprint1 (Want to keep this one dynamic)
@app.route('/app1/')
@app.route('/app1/<path:path>/')
def app1(path):
    ...
    return render_template(template, page = page)

#app-bluprint2
@app.route('/app2/', defaults = {'path': ''})
@app.route('/app2/<path:path>')
def app2(path):
    template = 'app2/index.html'
    page = 'home'
    if path != '':
        template = '/app2/%s.html' %path[-1]
        page = path[:-1]
    return render_template(template, page = page)

@freezer.register_generator
def handle_route():
    print "Generating Static Files Links"
    appDir = os.listdir('templates/app2')
    for filenames in appDir:
        if filenames == 'index.html':
            yield {'path': ''}
        elif filenames != 'base.html':
            yield {'path': '%s/' % filenames[:-5]}

#app-bluprint3 (Want to keep this dynamic)
@app.route('/app3/', defaults = {'path': ''})
@app.route('/app3/<path:path>')
def app3(path):
    ...
    return render_template(template, page = page)

if __name__ == '__main__':
    freezer.freeze()
    app.run(debug=app.config['DEBUG'], port=app.config['PORT_NUMBER'])

I am getting an error "MissingURLGeneratorWarning: Nothing frozen for endpoints app1, app2. However, I do not want to freeze anything for these endpoints. Is there a way to turn this warning off?

Answer 1

Yes, there are a couple:

1. Run Python with the -W flag:

   python -W ignore:'.*':flask_frozen.MissingURLGeneratorWarning
   

2. Filter such warnings in your __main__ entry:

   if __name__ == '__main__':
       from warnings import simplefilter as filter_warnings
       filter_warnings('ignore', 'flask_frozen.MissingURLGeneratorWarning')
