python - Add dynamic field to django admin model form

I need to add the field with link to the model view on my site to the django admin view. When I add field name to the list_display and define method for rendering this url:

class SetAdmin(admin.ModelAdmin):
    list_display = ['many other fields', 'show_set_url']

    def show_set_url(self, obj):
            return '<a href="#">Set</a>' # render depends on other fields

It shows in Sets list in django admin, but not in model form. How can I fix this and add link to the Sets Form in django admin?

I've tried also to create custom form for this model:

from core.models import Set
from django import forms

class SetAdminForm(forms.Form):
    class Meta:
        model = Set

    def __init__(self, *args, **kwargs):
        super(SetAdminForm, self).__init__(*args, **kwargs)
        self.fields['foo'] = forms.IntegerField(label=u"Link")

But there is now visible effect in form.

You can accomplish what you're trying by overriding ModelAdmin but you also need to override ModelAdmin.get_fieldsets. This answer might help you out. The OP in the link has a similar problem as well.

Edit: If you don't want an editable field you can try overriding ModelAdmin.get_readonly_fields. Also check here for more attributes to override.
