Solution 1 :

Both your routes are the same? I’m assuming lakas should be its own page so you should change @app.route(‘/’) to @app.route(‘/lakas’)

@app.route('/')
def home():
    template_table = {
        'title': "Home Control System"
    }
    return render_template('home.html', **template_table)

@app.route('/')
def lakas():
    return render_template('lakas.html')

Change the url in home.html to <a href="{{ url_for('lakas') }}">Lakás</a>

I think you might be having trouble understanding routes. An understanding of MVC might help.

Problem :

I’m new to html, i have researched a lot, but cannot solve this issue. I’m sure for you it is trivial, but I stuck.

So
I have a flask webserver. that is the code:
it is so simple, just loading the home.html and I guess the issue will be here somewhere, but I cannot find it.
all html docs are in the same folder, in the templates. the home.html loading nicely, but nothing other. I mean if I change in the return render_template the html it will be loaded, but not throug the webpage by clicking.

from flask import Flask, render_template


app = Flask(__name__, template_folder='templates')


@app.route('/')
def home():
    template_table = {
        'title': "Home Control System"
    }
    return render_template('home.html', **template_table)

@app.route('/')
def lakas():
    return render_template('lakas.html')


if __name__=='__main__':
    app.run(debug=True, host='0.0.0.0')

this is the home.html code:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>{{ title }}</title>
    <link rel="stylesheet" type="text/css" href="../static/css/style.css?version=15">
    <script type="text/javascript" src="../static/js/scripts.js?version=2"></script>
</head>
<body onload="renderTime()">
    <div class="wrapper">
        <div style="font-size: 1.5em", style="font-weight: bold">Menü</div>
        <div class="nested_1">
            <div align="right">Home Control System</div>
            <div id="clockDisplay" align="right"></div>
        </div>
        <div class="nested_2">
            <a href="overview.html" target="targetframe">Főoldal</a>
            <a href="lakas.html" target="targetframe">Lakás</a>
            <a href="garazs.html" target="targetframe">Garázs</a>
        </div>
        <iframe src="overview.html" name="targetframe" allowTransparency="true" scrolling="no" frameborder="0"></iframe>
    </div>
</body>
</html>

the folder structure is:

main
   static
   templates
       home.html
       lakas.html
       garazs.html

and if I simple open the home.html everything works perfectly, I can click on the buttons(Főoldal, Lakás, Garázs)

but, when I run the flask app and I reach that through the IP I have the home page, but 404 for the rest of them. I attach picture about the ok screen and the 404.
Not found screen
OK screen
What should I change? Could you help me please?
