------------------------------------------+-------------------------------
When using inlines in Django admin, it renders very poorly even when
creating a new element (so no data to load, database time always the
same).
And the higher the number in "extra" parameter, the longer it takes to
load the form.
{{{
class EffectModifierInline(admin.TabularInline):
model = EffectModifier
extra = 1
@admin.register(Effect)
class EffectAdmin(admin.ModelAdmin):
fieldsets = (
# Whatever
)
inlines = [EffectModifierInline]
# TODO:
list_display = ()
list_editable = ()
list_filter = ()
def get_queryset(self, request):
return super().get_queryset(request).prefetch_related('modifiers')
}}}
