How to bind django sql queries to a view and send the result to the template?

Question

Django

There is a method

def main_rospis(request):
    pred = Rospisanie.objects.raw('Select full_name as den, vremy as nachalo, nazvanie as gruppa, name as predmet, surname as prepod from DniNedeli_dninedeli INNER JOIN rospisanie_rospisanie ON DniNedeli_dninedeli.id = rospisanie_rospisanie.kod_dny_r_id INNER JOIN urok_urok ON urok_urok.id = rospisanie_rospisanie.urok_r_id INNER JOIN gruppa_gruppa ON gruppa_gruppa.id = rospisanie_rospisanie.gruppa_r_id INNER JOIN predmet_predmet ON predmet_predmet.id = rospisanie_rospisanie.predmet_r_id INNER JOIN prepod_prepodavatel ON prepod_prepodavatel.id = rospisanie_rospisanie.prepod_r_id')

    return render(request, 'papka/list.html', {'preds':pred})

in the template (list.html) is not displayed. How can I fix it?
in general I need to execute this query and get the result.
the request itself is correct.
