Have you read [this post](https://stackoverflow.com/q/44109/4744341)? I suppose it may contain the information you need. — natka_m, Jul 21 '19 at 20:26

From `field structure is dblookup combobox it means i want read it from database` it sounds like you might be looking for a `ForeignKey.limit_choices_to`? https://stackoverflow.com/a/252087/1101109 — pzrq, Jul 22 '19 at 01:19
