In a code example there is no open single quotes `shop/product/detail.html',`:

```python
def product_detail(request, id, slug):
 product = get_object_or_404(
 Product, id=id, slug=slug, available=True
 )
 return render(
 request,
 shop/product/detail.html', # <<<<<<
 {'product': product}
 )
```
