Django，我无法将变量从视图传递到 html 模板

Question

Good day, I'm new to Django and following CS50Web. I've been having a headache for a couple of days trying to understand why this is not working. Basically we have a Flights model and a Passengers model with a many-to-many relationship. here is the views.py code:

def flight(request, flight_id):
    flight = Flight.objects.get(pk=flight_id)
    passengers = flight.passengers.all()
    print(passengers)
    return render(request, "flights/flight.html", {
        "flight": flight,   
        "passengers:": passengers
    })

and here is the html:

<h2> Passengers </h2>
    <ul>
        {% for passenger in passengers %}
            <li>{{ passenger }}</li>
        {% empty %}
            <li>No passengers.</li>
        {% endfor %}
    </ul>

I know the passengers variable is not empty, the print statement returns: "<QuerySet [<Passenger: Fidel Castro>, <Passenger: James Bond>, <Passenger: Larry Bird>]>"

Still, the rendered Html page always shows no passengers!

Could a good soul help me understand what I'm I doing wrong? Because I'm out of ideas at this point. Thank you in advance

Answer 1

Try to not use the same variables name as in your models fields or model name.

Answer 2

Remove the colon ":" at the end of "passengers:" in the context dictionary.
