Re: How to implement a form to update the quantity?

Hi!

You can use something like:

{% for item in garage.garagecar_set.all %}
              Car:      {{item.car.name}}              Price:    {{item.car.price}}               Quantity: {{item.quantity}}               ID:       {{item.car.id}}
              <form action="../update_q/{{item.pk}}/" method="post"/>
              {{form.q}}
              <input type="submit" value="update"/>
              </form>
 {% endfor %}

and view like

def update_q(request, garagecar_id):
      # get garagecar by id here, create form from request, set new value, save()


it to submit forms with ajax, to not reload entire page every time.


P.S.

it looks you are implementing Many-to-Many-Through relation. Django has support for it out of the box
