Anyone can welp-me givin an exemple of Many to many nested form?
I have the situation
a model called contract and a model called parts,
a contract can have and be lrelated to many parts
i have the folowing Schema
Contract
→ title
→ start_date
→ due_date
→ file
Part
→ first_name
→ last_name
→ email
→ cpf
→ phone
ContractPart
→ contract_id
→ part_id
So how i can make a nested form to create those relationship between models?
exemple: i have a contract, A and a part B, C
so i want to related part B,C to contract A
but i havent any ideia how i can make a nested_form with a select to create this association
