該錯誤明確引用了表單,而您沒有發佈它? – sevenseacat

@卡羅爾哎喲對不起,它是.. – js111

您需要確保您的模型:occasions嵌套的屬性:

class User ActiveRecord::Base 
    has_many :occasions 
    accepts_nested_attributes_for :occasions 
end 

否則表單生成器不沒怎麼使用Occasion對象,你正在構建在控制器中,所以它會只使用:occasions符號作爲「對象」,給你這個錯誤。

我討厭挑剔,但它'recep_nested_attributes_for'而不是'accept_nested_attributes_for' – J3RN
