Display link to full change form for object in dja

问题:

Because nested inlines are not yet supported, I am wondering how to display a link to the related object as an alternative. I came across a question the other day with a link to an app, but I can't seem to find it again.

Here is what I am looking at doing:
I have a manager model that contains name, address etc.

I have a property model that has inlines and is related to the manager model.

I am wanting the manager model to be able to display a link in the change form for each of the properties that are related to it.

Is this something that can be done?

Sure, you can just overwrite your change view. http://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.change_view

Copy the template from the real admin template directory and place it anywhere you like (since you can point at it with change_form_template, and add in some extra stuff to display.

I do this pretty commonly.

class MyModelAdmin(admin.ModelAdmin):
    change_form_template = 'myapp/new_change_form.html'

    def change_view(self, request, object_id, extra_context=None):
        properties = Manager.objects.get(id=object_id).property_set.all()
        extra_context = { 'properties':properties }
        super(MyModelAdmin, self).change_view(request, object_id, extra_context)

Find a place in the admin template to add some of your own HTML.

<ul>
{% for property in properties %}
    <li>
        <a href="{% url admin:myapp_manager_change property.id %}">Edit {{ property }}</a>
    </li>
{% endfor %}
</ul>
