Error: 'QuerySet' object has no attribute, even if the attribute exist

Question

I have the following code:

  company = Company.objects.filter(account=self.account).only('slug')
        if company:
            return redirect(reverse_lazy('company:detail_a', kwargs={'slug': company.slug}))

I get the error:

'QuerySet' object has no attribute 'slug'

The slug attribute definitely exist(checked in model/database). I tried to access it like in a template.

So I tried with other attributes, 'name', because appears when I print the QuerySet.

So I think the QuerySet is not evaluated or something like that, but I don't know how to force to do it.

A QuerySet is a collection of instances. The collection doesn't have any of those attributes; only the individual instances do.

If you want to get an individual instance, use get instead of filter.

filter will return a query set not a model object if you want a single object not a queryset try filter with first

  company = Company.objects.filter(account=self.account).only('slug').first()
  if company:
      return redirect(reverse_lazy('company:detail_a', kwargs={'slug': company.slug}))

OR

company = Company.objects.only('slug').get(account=self.account)
  if company:
      return redirect(reverse_lazy('company:detail_a', kwargs={'slug': company.slug}))

if you try to use it on a detail-page try this:

 <a href="{{ object.get_add_to_cart_url }}" class="cart-btn">Add to cart</a>

instead of:

    <a href="{{ item.get_add_to_cart_url }}" class="cart-btn">Add to cart</a>
