For people that wanna do the same thing, just change the "href" of the button on "base.html"

Example:
You wanna go to login page, so instead of "#" on the href, set it to "login"

You are Awesome Tim. You have the best tutorials and your way of explaining is great.

@Tech With Tim -- at @8:49 to resolve that issue with flash( f"...{user}..." ), just move the flash() to AFTER you complete the session.pop -- because that returns the value of who just got logged out, and thus you can pass that into your flash( f"...string..." ).

Thank you for your Flask Tutorial. Your video was literally the highlight of my life so far

@4:55 there is some audio artifact but other than that the vidoe and the whole series is very educational and enjoyable.

Great video!! if we want to display message as alert box, type like this in the block in html page




{% with messages = get_flashed_messages() %}
{% if messages %}
{% for msg in messages %}
<p id="p1" style="display: none;">{{msg}}</p>
{% endfor %}
{% endif %}
{% endwith %}
<script>
var
window.alert(m)
</script>

Great tutorial! Thanks.
I followed along and now I have question.
In the base.html I put 2 variables: content and name. And when I call render_template all is fine. But if use e.g. redirect(url_for("user")) then the places where the variables go into stay empty (of course ;-) ) - How to I tell the redirect(url_for()) to use these values as well?

the last error was working for me somehow n i have no idea what im doin lol

[deckplate]

Naming everything user and not changing it up even a little bit (usr, user_vari, etc) makes it very complicated Tim

[لنتسقطامةرسولهامحمدوصاحبهعمرال]

[thegaribovv]

I think you have to add requirements before tutorial, for example: 1) HTML, css, Js 2)Python dictionary 3)Python loops and etc

[omerg]

Great vids series Tim

B.T.W couldn't find the NavBar you're using in bootstrap
can you refer to it?

Thx

[NataliaRevenga]

do you really need to write the html block? My message gets flashed without it. Is this block only useful if one needs to display several messages?

[hejhej]

Really enjoying the series!
However, could you show us how to enter some values on one page, then get redirected to another page where a chart has been made based on those values.

[jayden]

Can you tell me how to modify the nav bar?

[ПерсіДжексон-жи]

I have a problem. When I make all this in "login.html", I become an error that 'get_flashed_massages' is undefined

[dhm]
