У меня есть форма, где у меня есть таблица с флажками, чтобы выбирать строки и сохранять идентификаторы в моей БД.Сильные параметры: отсутствует хэш-пара или пустое значение
Но он бросает мне ошибку:
Param is missing or the value is empty: leadallocation"
Я пробовал разные способы, но все еще и не работают. Поэтому на данный момент я просто палочку, чтобы сохранить хэш в моем db. Благодарю.
# Never trust parameters from the scary internet, only allow the white list through.
def leadallocation_params
params.require(:leadallocation).permit(:campaign_id, :company_id, :user_id)
end
