Show children inline in Django admin

In Django 1.11, I have 2 models, Foo and Bar:
class Foo(models.Model):
name = models.CharField()
class Bar(models.Model):
name = models.CharField()
foo = models.ForeignKey(Foo)
When I visit the Foo page in the Django admin, I want to be able to see a list of its Bars underneath it. So I do this in admin.py:
class BarInline(admin.StackedInline):
model = Bar
@admin.register(Foo)
class FooAdmin(admin.ModelAdmin):
list_display = ('name')
fields = ('name')
inlines = [BarInline]
But what I really want is a list of clickable links to a separate page where I can edit each Bar (as well as a Add button to add a new Bar to this Foo). I.e. I don't want the entire inline form. How is this possible in Django?

You can create a callable readonly field which will return the reversed admin url of each relation wrapped in the relevant html code.
This will result in something like:
"your readonly field": link1, link2, link3

@GluePear Reverse relations are called with<model_name>_setunless you set arelated_name. On error, this callable will fail silently, I think. Try:>>> p = Foo.objects.first()and then>>>dir(p)to see how you can call the relatedBar. Otherwise, installipdband try to setimport pdb; pdb.set_trace() # XXX BREAKPOINTbeforereturnto get a debugging prompt.

@GluePear There is also a gotcha in theadmin:yourapp_bar_change.yourappis the name of the application your modelBarlies in.yourproject/yourapp/models.py. You can also find it in the admin url when you change an instance of the modelBar: Something likehttp://127.0.0.1/admin/yourapp/bar/1/change/. I changedyourappto{{ app_label }}as in the docs.

You can make all the fields readonly in BarInline.
class BarInline(admin.StackedInline):
model = Bar
readonly_fields = ('id', 'name', 'foo')
extra = 0
And for the Add functionality you can modify the inline template or more easy probably, add a custom field in FooAdmin, something like:
class FooAdmin(admin.ModelAdmin):
list_display = ('name')
fields = ('name', 'custom_add_bar')
inlines = [BarInline]
def custom_add_bar(self, obj):
add_url = reverse('admin:appname_bar_add')
return mark_safe(f'<a href="{add_url}">Add Bar</a>')
