Describe your issue

When we added the package django-axes and tried to open a detail view from one of their model objects, we get this error:
AttributeError: 'AccessLogAdmin' object has no attribute 'compressed_fields'

There are 2 places in templatetags.unfold where adminform.model_admin.compressed_fields is accessed.

The issue is, that we have to create custom ModelAdmin classes with unfold and unless you do that, you'll get this error.

My suggestion is:
a) add a check for this attribute (+ maybe a log warning, that it's recommended to use unfold.admin.ModelAdmin)
b) add a more precise error message

Regarding a)
adminform.model_admin.compressed_fields -> hasattr(adminform.model_admin, "compressed_fields") and adminform.model_admin.compressed_fields
This way the detail page is at least working.

Regarding b)

if not hasattr(adminform.model_admin, "compressed_fields"):
    raise Exception(f"{adminform.model_admin} has no compressed_fields attribute. Please ensure that the model admin class is inheriting from unfold.admin.ModelAdmin")
