Update single field

Question

I have a Customer class which has a representative field....this field is initially blank but when the user opens up the details page of the chosen customer, they'll be given the open of representing this customer by clicking on a link. The template layout I was thinking of is this:

<strong>Representative: </strong>
{% if customer.representative %}
   {{ customer.representative }}
{% else %}
   <a href="{% url representCustomer customer.id %}">Represent this customer.</a>
{% endif %}

All that remains is the view to effect this...this is where I'm stuck.

Answer 1

Just take the representative that the user belongs to and assign it to the representative field of the relevant customer model, then save.

Answer 2

You need to figure out customer from url and you can get current user from request, then it's merely two lines of view code:

customer = Customer.objects.get(pk=1)
customer.representative = Representative.objects.get(user=request.user)
customer.save()

That said, changing data by GET request is not recommended technique.
