View.py
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)
