django - 如何在 Django View 中使用 get 参数重定向？

Question

我想在 Django View 中使用 GET 参数重定向。由于某些原因，我想使用 GET 参数，而不是 url 参数。

def product_new(request):
    group = request.GET.get('group')
    if group == None:
        product = Product.objects.create()
        return redirect('cms:product_list_edit')
    else:
        product = Product.objects.create(group=group)
        rreturn redirect('cms:product_list_edit') # I want to redirect this url with GET parameter.

对于python3及以上:

def redirect_with_params(viewname, **kwargs):
    """
    Redirect a view with params
    """
    rev = reverse(viewname)

    params = urllib.parse.urlencode(kwargs)
    if params:
        rev = '{}?{}'.format(rev, params)

    return HttpResponseRedirect(rev)

使用:

redirect_with_params('main-domain:index', param1='value1', param2='value2')
