如何在Django中“添加到购物车”模型对象

Question

I'm trying to work out how to use a very simple bit of "shopping cart" functionality, but I'm no good at this.

Let's say I have a simple queryset, "objectos" that comes from:

# models.py:
class ObjectModel(models.Model):
    title = models.CharField(max_length=30)
    ...
    content = models.TextField()


# views.py
def product_list(request):
    objectos = ObjectModel.objects.all()
    return render(request, 'frontpage/object_list.html', {'objectos':objectos})

..And let's say I need to insert a simple button in the template that grabs an object from the queryset and puts the object in another queryset. This is what I can't figure out; how to do that secondary queryset..

Anyway, here's a simplified look at what I'm trying to do in the template:

<!-- template -->
{% for obj in objectos %}
  {{ obj.title }}
  {{ obj.content }}
  <a href="#">
    <button type="button">add to other qs!</button>
  </a>
{% endfor %}

How could this be done in a simple fashion?

I'm considering building a shopping cart, only a lot simpler, but I'm not sure that's the right way to approach it. If you coulddirect me to a good shopping cart tutorial or similar that I could look at, I'd be most grateful :)

Answer 1

There are a lot of ways you can do this, but the best way would be to follow a tutorial which has easy steps to follow and explains throughout the way. I did some research, and this looks like a great tutorial which has multiple pages, each one explaining a different part of building a simple shopping cart.
