Ho due tabelle in relazione uno a molti:
la seconda:
def self.up
t.timestamps
end
foreign_key(:categories, :sector_id, :sectors)
end
per le foreign keys ho creato un helper come aveva suggerito qualcuno
Sector(#70182185518660 ) expected, got String(#70182230246400 )
Mi sfugge qualcosa?

category.sector = 1
perchè lui si aspetta (come ti dice) un settore e non una stringa (che poi

hai inserito tanti dati, ma non quelli essenziali, tipo il traceback.

non sono iscritto alla ml da molto tempo, ma ti posso dire che in
