使用Django将多个相关对象添加到父模型

Question

I'm trying to add multiple related objects to a parent object with Django.
The error i get: int() argument must be a string or a number, not 'Tag'

My code looks like this:

def ask(request):

    form = AskQuestionForm

    if request.method == 'POST':

        form = AskQuestionForm(request.POST)

        if form.is_valid():

            tags = request.POST.getlist('tags')

            # Category
            qcat = Category.objects.filter(id=request.POST.get('category')).first()

            o = Question.objects.create(
                title = request.POST.get('title'),
                body = request.POST.get('body'),
                category = qcat,
                user = request.user
            )

            for t in tags:
                rt = Tag.objects.get_or_create(word=t)
                o.tags.add(rt)

            return redirect('questions.index')

    return render(request, 'questions/ask.html', {
        'form' : form
    })

I want to add tags to question object. What am I doing wrong?

Answer 1

get_or_create() returns a tuple of (object, created) . So change the tag creation to:

rt, _ = Tag.objects.get_or_create(word=t)
