Flask page not found after a post request

Question

I'm creating this online simple webbapp, into i need to know what user voted. In the home page, I can see the list of "surveys", with two options in a radiobutton, and a submit button, as you can see in the following code

{% for element in range(1,datas.count()+1) %}
    {% if datas.filter_by(id=element).first().user_name != user.name  %}
    <form action="post">
        <fieldset style="border:{% if user.name in datas.filter_by(id=element).first().voters %}#f00 solid 2px {% else %}#00f solid 2px{% endif %};" class="fild"> 
            <legend>{{ datas.filter_by(id=element).first().question }}</legend>
            <br><br>
            {{ datas.filter_by(id=element).first().fAnsw }} <input type="radio" name="opt" value="fa"/>
            {% if user.name in datas.filter_by(id=element).first().voters %}
            <progress value="0" max="100"></progress>
            {% endif %}
            {{ datas.filter_by(id=element).first().sAnsw }}<input type="radio" name="opt" value="sa"/>
            {% if user.name in datas.filter_by(id=element).first().voters %}
            <progress value="0" max="100"></progress>
            {% endif %}
            <br><br>
            {% if user.name not in datas.filter_by(id=element).first().voters %}
            <button type="submit" id="ans">Conferma</button>
            {% endif %}
        </fieldset>
    </form>
    {% endif %}
{% endfor %}

Now, I want to put on the vote on the database, based on what the users chose. So, I wrote the following code in Flask

@views.route("/", methods=["GET", "POST"])
@views.route("/home", methods=["GET", "POST"])
@login_required
def home():
    if request.method =="POST":
        selected = request.form.getlist('opt')
        print(selected)
    return render_template("home.html", user=current_user, datas=Refs.query)

Then, after a lot of resarch, I haven't found out why, when I press a submit button it redirect me to a page with the following link:

http://127.0.0.1:5000/post?opt=fa

and so it gaves me a 404. I would like to know why it doesn't redirect me to the same page, so I can handle it via the Flask code. And after that, how can I pass the survey that user touched? I have some issues. Please help
