How can I access obj in admin.py

[Mike Dewhirst]

I want to adjust inlines based on a property of the object.

class SubstanceAdmin(admin.ModelAdmin):

class SolidInline(admin.StackedInline):
pass
class LiquidInline(admin.StackedInline):
pass
class GasInline(admin.StackedInline):
pass

inlines = get_inlines

def get_inlines(self):
obj = how_do_I_get_this(?)
if obj.physical_state = None:
return ((SolidInline), (LiquidInline), (GasInline))
elif obj.physical_state = 1:
return ((SolidInline), )
elif obj.physical_state = 2:
return ((LiquidInline), )
elif obj.physical_state = 3:
return ((GasInline), )

Many thanks for a miracle :)

You want to override get_inline_instances: https://docs.djangoproject.com/en/1.11/ref/contrib/admin/#django.contrib.admin.ModelAdmin.get_inline_instances
