If I upload a file to my flask script and I don't like it, I set filename to "None" so it shows a default image. Then, in my Flask template, I want to test to see if filename is "None"; if so, show the default. Else, show the file. Here is my template code, which does not work:
<!doctype html>
<title>Hello from Flask</title>
{% if {{filename}} is "None" %}:
<h1>some text<img src="{{filename}}"> more text!</h1>
{% else %}
<h1>Impossible file: here is tha default so<img src="MB.png"> boi</h1>
{% endif %}
I think the problem lies in the string compare. I cannot figure out how to properly compare strings, I think.
Thanks!

What about this?
{% if filename == "None" %}
You don't need double brackets inside {% %}
