How do I use url_for if my method has multiple route annotations?

Question

So I have a method that is accessible by multiple routes:

@app.route(\"/canonical/path/\")
@app.route(\"/alternate/path/\")
def foo():
    return \"hi!\"

Additionally, for those using a catch all route constructed with variables: Flask will correctly create the url path if url_for is passed a dictionary containing the variables.

For example...

app.py:

app.route('/')
app.route('//')
def catch_all(pattern1, pattern2=None):
    return render_template('template.html', p1=pattern1, p2=pattern2)

app.route('/test')
def test_routing:
    args = {'pattern1': 'Posts', 'pattern2': 'create'}
    return render_template('test.html', args=args)

test.html:

click here

When you click on the 'click here' link, you will be directed to the 'Posts/create' route.
