Flask Flash Messages Blank

[Leaf]

View.py

@site.route('/dashboard/')
def dashboard():
    flash("flash test!!!!")
    flash("fladfasdfsaassh test!!!!")
    flash("asdfas asfsafs!!!!")
    return render_template("dashboard.html")

dashboard.html

  {% with messages = get_flashed_messages() %}
         {% if messages %}
         <p>
             Message was validated and flashed from view, check
             list to see if successful:
         </p>
         <ul>
             {% for messages in messages %}
                <li>{{ message }}</li>
             {% endfor %}
         </ul>
         {% endif %}
         {% endwith %}

This is what is printed:
Message was validated and flashed from view, check list to see if successful:

I first had the problem when I was trying to create a form using Form-WTF and Miguel Grinberg's tutorial. I thought maybe I was doing something wrong as the list was registering my flashes but printing them all blank, to test it I created dashboard.html and printed only flashes and received the same problem. I researched in as many different ways as I could flask/flash problems. But have not discovered the problem thus far.

Someone suggested it could be a server issue; but I'm new to python and don't know how to check for server issues, nor do I know how to change the server name since I didn't set it. I did go to __init__.py and type SERVER_NAME = app.localhost as I read someone else said that worked for them; but this did not work for me.


Note:
In the original code I had tested return redirect. As someone said return redirect was their problem, while another said (when I researched the problem), that the server was their issue; and so for the former using return render_template fixed it as opposed to: "return redirect('/index')" So I tried render_template, and when that rendered blank I was out of ideas for how to solve. (just adding that information to show I've tried multiple solutions that I can think of based on the search engine but still drawing up well...blanks)

didn't test it, but first fix line 8 in html file - you have messages twice. Should be {% for message in messages %}

Wow, something so simple; that fixed the problem; thank you so much!
