HI all,
I have 2 tables: groups and items. The relation is 1-* (each group has
many items). In reality each groups should have at least 4 items.
How can I implement an input form so I can input 4 items at the same
time?
And how can I validate the input to ensure that each group must have >=4
items?
Thank you so much for replies.
