Disable link to edit object in django's admin (display list only)?

In Django's admin, I want disable the links provided on the "select item to change" page so that users cannot go anywhere to edit the item. (I am going to limit what the users can do with this list to a set of drop down actions - no actual editing of fields).

I see that Django has the ability to choose which fields display the link, however, I can't see how I can have none of them. 

class HitAdmin(admin.ModelAdmin):
    list_display = ('user','ip','user_agent','hitcount')
    search_fields = ('ip','user_agent')
    date_hierarchy = 'created'
    list_display_links = [] # doesn't work, goes to default

Any ideas how to get my object list without any links to edit?

I wanted a Log viewer as a list only.

I got it working like this:

class LogEntryAdmin(ModelAdmin):
    actions = None
    list_display = (
        'action_time', 'user',
        'content_type', 'object_repr', 
        'change_message')

    search_fields = ['=user__username', ]
    fieldsets = [
        (None, {'fields':()}), 
        ]

    def __init__(self, *args, **kwargs):
        super(LogEntryAdmin, self).__init__(*args, **kwargs)
        self.list_display_links = (None, )

It is kind of a mix between both answers.

If you just do self.list_display_links = () it will show the link, Anyway because the template-tag code (templatetags/admin_list.py) checks again to see if the list is empty.

just write list_display_links = None in your admin

In more "recent" versions of Django, since at least 1.9, it is possible to simple determine the add, change and delete permissions on the admin class. See the django admin documentation for reference. Here is an example:

@admin.register(Object)
class Admin(admin.ModelAdmin):

    def has_add_permission(self, request):
        return False

    def has_change_permission(self, request, obj=None):
        return False

    def has_delete_permission(self, request, obj=None):
        return False

I overrided get_list_display_links method and action to None.

class ChangeLogAdmin(admin.ModelAdmin):
    actions = None
    list_display = ('asset', 'field', 'before_value', 'after_value', 'operator', 'made_at')

    fieldsets = [
        (None, {'fields': ()}),
    ]

    def __init__(self, model, admin_site):
        super().__init__(model, admin_site)

    def get_list_display_links(self, request, list_display):
        super().get_list_display_links(request, list_display)
        return None

I build a mixin based on @simpleigh 's solution.

class DeactivatableChangeViewAdminMixin:
    """
    Mixin to be used in model admins to disable the detail page / change view.
    """
    enable_change_view = True

    def can_see_change_view(self, request) -> bool:
        """
        This method determines if the change view is disabled or visible.
        """
        return self.enable_change_view

    def get_list_display_links(self, request, list_display):
        """
        When we don't want to show the change view, there is no need for having a link to it
        """
        if not self.can_see_change_view(request=request):
            return None
        return super().get_list_display_links(request, list_display)

    def change_view(self, request, *args, **kwargs):
        """
        The 'change' admin view for this model.

        We override this to redirect back to the changelist unless the view is
        specifically enabled by the "enable_change_view" property.
        """
        if self.can_see_change_view(request=request):
            return super().change_view(request, *args, **kwargs)
        else:
            opts = self.model._meta
            url = reverse('admin:{app}_{model}_changelist'.format(
                app=opts.app_label,
                model=opts.model_name,
            ))
            return HttpResponseRedirect(url)

The benefit is that you can reuse it and you can furthermore make it conditional

Build for django 3.2.8.

To be used like this for a static approach:

class MyAdmin(DeactivatableChangeViewAdminMixin, admin.ModelAdmin):
  enable_change_view = False

And like this for a non-static one:

class MyAdmin(DeactivatableChangeViewAdminMixin, admin.ModelAdmin):  
    def can_see_change_view(self, request) -> bool:
        return request.user.my_condition
