Here’s a function in my application that returns a number from a database and I’m trying to display it on my webpage using flask
def handler():
increment_visitor()
return retrieve_visitor_count()
@app.route('/')
def home():
handler()
return render_template("index.html", count=handler)
I assign the name count to handler and try displaying count in my index.html file like so:
<p>{{count}}</p>
When I load my webpage, here’s what the output is
<function handler at 0x7f8c70069a60>
When I print my handler function, it outputs the appropriate number, so how do I get that number to display on my webpage correctly?
>Solution :
count is handler, which is a function. Add parentheses to call it in the template like so:
{{count()}}
Looking at your logic though, I think you may want something like this:
@app.route('/')
def home():
result = handler()
return render_template("index.html", count=result)
Otherwise you would presumably increment the visitor count twice
