in Django, multiple select input just returns a single value?

I have a very simple form with a "select" field. For each user in the app it creates an option field, that works fine:

<select name="users" id="users" multiple>
        <option value="{{admin.id}}" selected>{{ admin.username }}</option>
        <!-- can I delete the admin from this list? -->
        {% for user in users %}
            <option value="{{user.id}}">{{ user.username }}</option>
        {% endfor %}
</select>

Now when I try to retrieve the values of "users", even if they are all selected I always just get a single value...:

 if request.method == "POST":
        title = request.POST["title"]
        admin = request.user
        project_users = request.POST["users"]

        print(project_users)

I just get "1" or "2" but not a list? How can I retrieve all of the values from this multiple select?

If you subscript request.POST you get the last value that was matched with the given key, even if there are multiple.

You can make use of .getlist(…) [Django-doc] to obtain a list of values. The list will be empty in case no values match with the given key:

if request.method == 'POST':
    title = request.POST['title']
    admin = request.user
    project_users = request.POST.getlist('users')

    print(project_users)

It might however be more convenient to work with forms [Django-doc] to validate and clean the request data.
