Accessing the models fields DetailView

Question

The problem i am having is I can't access a model's fields in the html {{ profile.slug }}. In the template I can access the model, let me show you.

I have 2 models Profile, and Oferto. In Detail view on the Oferto Model, I want to link to the user's profile who created the Oferto. the Oferto Model has a field user,

I am trying to lookup the profile.slug that coresponds to the Oferto.user

The following is seen in the browser from a test

[<Profile: Red>]
Name: oFFER

User: Red

Description:

Time:    9

Stelo:   None

Requirements:9

and the template is as follows

{% block content %}
<a>{{ profile }}</a>

    <p>Name:        {{ oferto.name }}</p>
    <p>User:        {{ oferto.user }}</p>



    <p>Description: {{ oferto.descripion }}</p>
    <p>Time:        {{ oferto.time }}</p>
    <p>Stelo:       {{ oferto.stelo }}</p>
    <p>Requirements:{{ oferto.requirements }}</p>
                <hr>
    <p>Location:    {{ oferto.location }}</p>
    <p>tags:        {{ oferto.tags }}</p>
    <p>{{ PROJECT_URL }} / {{ STATIC_URL }}{{ oferto.image }}</p>


{% endblock %}

if i try to use profile.slug it just comes up blank and is not in the html

views.py

class OfertoDetailView(ExtraContextMixin,DetailView):
    model = Oferto

    def extra(self):
        profile = Profile.objects.all()
        return dict(profile = profile)

class ExtraContextMixin(object):

    def get_context_data(self, **kwargs):
        context = super(ExtraContextMixin, self).get_context_data(**kwargs)
        context.update(self.extra())
        return context

    def extra(self):
        return dict()

if your wondering why I am using a mixin see an answer from django - DetailView how to display two models at same time

Answer 1

profile is a queryset, not an instance. Querysets don't have a slug attribute.

You either need to get a specific instance of Profile in your extra method, or iterate through the profiles in your template.

Answer 2

The fact that [<Profile: Red>] is visible in the test output indicates that you are passing Profile instance to the template correctly.

Therefore the problem lies within profile.slug. Are you sure that you have slug field on your Profile class?
