¿Cómo puedo dar def formfield_for_manytomany una identificación de objeto editable?

Answer 1

Suponiendo que está buscando la instancia de Report editada por ReportAdmin , intente esto:

class ReportAdmin(admin.ModelAdmin):
def get_object(self, request, object_id):
# Hook obj for use in formfield_for_manytomany
self.obj = super(ReportAdmin, self).get_object(request, object_id)
print "Got object:", self.obj
return self.obj
def formfield_for_manytomany(self, db_field, request, **kwargs):
if db_field.name == "r_precursor" and getattr(self, ''obj'', None):
kwargs["queryset"] = Precursor.objects.filter(
ops_area=self.obj.ops_area)
return super(ReportAdmin, self).formfield_for_manytomany(
db_field, request, **kwargs)
