How to flashing a message with link using Flask flash?

Question

I\'m creating a web app using Flask to deal with GoogleOpenID, these codes are almost finished, except the flashing message contains a link:

@oid.after_login
def

You need to render a template after calling flash() which should then get the message using get_flashed_messages(). You need to adjust your code to call a template after calling flash(). flash sends the message to next request which can be extracted by the template. The template can look something like:

{% with messages = get_flashed_messages() %}
    {% if messages %}
    

    {% for message in messages %}
        
{{ message | safe }}
    {% endfor %}
    
  {% endif %}
{% endwith %}

In your view code, I would add a render_template right after the flash() call. Something like:

flash('success')
return render_template('whatever.html')
