AttributeError: 'str' object has no attribute 'days'

when I try to add an item to a vendor it calls the POST method when this *view is called it shows an error that 'str' object has no attribute 'days'. if you want any other files to tell I hope someone will fix this issue.

class AddBaseproductToStore(AdminOnlyMixin, generic.TemplateView):
template_name = 'vendor-admin/add-product-to-store.html'

def get_context_data(self, **kwargs):
    # Call the base implementation first to get a context
    context = super().get_context_data(**kwargs)
    context['prod_id'] = self.kwargs['pk']
    context['vendor'] = self.kwargs['vendor']
    return context

def get(self, request, *args, **kwargs):
    product = BaseProduct.objects.get(id=self.kwargs['pk'])
    vendor_id = self.kwargs['vendor']
    base_cat = BaseCategory.objects.all()
    return render(request, self.template_name, {"product": product, "base_cat": base_cat, 'vendor': vendor_id})

this the continuation of above code

    def post(self, request, *args, **kwargs):
    base_product = BaseProduct.objects.get(id=self.kwargs['pk'])
    vendor_id = self.kwargs['vendor']
    base_category = BaseCategory.objects.get(id=request.POST.get('category'))
    try:
        p = Product.objects.get(base_product=base_product,
                                category=Category.objects.get(vendor_id=vendor_id, base_category=base_category))
    except ObjectDoesNotExist:
        product = Product()
        product.category = Category.objects.get(vendor_id=vendor_id, base_category=base_category)
        product.base_product = base_product
        product.name = request.POST.get('name')
        product.ar_name = request.POST.get('ar_name')
        product.sort_order = request.POST.get('sort-order')

        product.dryclean = request.POST.get('dryclean', '') == 'on'
        product.normal_dryclean_price = request.POST.get('dryclean_price')
        product.normal_dryclean_buffer_time = request.POST.get('dryclean_buffer')

        product.wash_and_pressing = request.POST.get('wash-press', '') == 'on'
        product.normal_wash_and_pressing_price = request.POST.get('wash-press-price')
        product.normal_wash_and_pressing_buffer_time = request.POST.get('wash-press-buffer')

        product.pressing = request.POST.get('press', '') == 'on'
        product.normal_pressing_price = request.POST.get('press-price')
        product.normal_pressing_buffer_time = request.POST.get('press-buffer')

        product.express_dryclean = request.POST.get('exp-dryclean', '') == 'on'
        product.express_dryclean_price = request.POST.get('exp-dryclean-price')
        product.express_dryclean_buffer_time = request.POST.get('exp-dryclean-buffer')

        product.express_wash_and_pressing = request.POST.get('exp-wash-press', '') == 'on'
        product.express_wash_and_pressing_price = request.POST.get('exp-wash-press-price')
        product.express_wash_and_pressing_buffer_time = request.POST.get('exp-wash-press-buffer')

        product.express_pressing = request.POST.get('exp-press', '') == 'on'
        product.express_pressing_price = request.POST.get('exp-press-price')
        product.express_pressing_buffer_time = request.POST.get('exp-press-buffer')

        product.save()
        if product.express_pressing == True or product.express_dryclean == True or product.express_wash_and_pressing_price == True:
            product.express = True
        else:
            product.express = False
        product.save()

    return redirect('admins:vendor_items', pk=vendor_id)

this is the error showing

\lib\site-packages\django\utils\duration.py", line 44, in duration_microseconds
    return (24 * 60 * 60 * delta.days + delta.seconds) * 1000000 + delta.microseconds
AttributeError: 'str' object has no attribute 'days'

Try the command py manage.py showmigrations. It gives out lists of migrations that has been applied and yet to be applied.

It looks something like this:

[X] 0012_alter_task_start_subtask_delete_calc
 [X] 0013_subtask_sub_duration
 [ ] 0014_alter_subtask_sub_duration
 [ ] 0015_alter_subtask_sub_duration

**check out the last migrated file.**In my case the problem was with the 13th file

class Migration(migrations.Migration):

    dependencies = [
        ('times', '0012_alter_task_start_subtask_delete_calc'),
    ]

    operations = [
        migrations.AddField(
            model_name='subtask',
            name='sub_duration',
            field=models.DurationField(default="00:10:00"),
            preserve_default=False,
        ),
    ]

In my case I had defined a string as default value for duration field which should be a datetime object instead. so replace it with default=datetime.timedelta()

convert all your times field to timedelta by parse_duration() method

eg:

from django.utils.dateparse import parse_duration
product.normal_dryclean_buffer_time = parse_duation(request.POST.get('dryclean_buffer'))

do it for all fields.
