如何更新記錄在rails控制器

Question

上午使用stripe供用戶訂閱。從那裏我收集條紋日期並保存在訂閱模式。我爲我的用戶模型創建枚舉以基於條帶訂閱ID分配不同的角色。 這裏是我的用戶模型看起來像

class User < ApplicationRecord 
    enum role: [:user, :gold, :platinum, :diamond ] 
    has_one :subscription 
    has_one :shipping 
    extend FriendlyId 
friendly_id :firstname, use: [:slugged, :finders] 

    # Include default devise modules. Others available are: 
    # :confirmable, :lockable, :timeoutable and :omniauthable 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable, :validatable 

end 

和波紋管是我的用戶控制器

def subscription_checkout 
    user = current_user 
    plan_id = params[:plan_id] 
    plan = Stripe::Plan.retrieve(plan_id) 
    # This should be created on signup. 
    customer = Stripe::Customer.create(
     description: 'Customer for test@example.com', 
     source: params[:stripeToken], 
     email: 'test@example.com' 
    ) 
    # Save this in your DB and associate with the user;s email 
    stripe_subscription = customer.subscriptions.create(plan: plan.id) 
    @sub = Subscription.create(plan: stripe_subscription.plan.name, 
           stripeid: stripe_subscription.id, 
           user_id: current_user.id, 
           customer: stripe_subscription.customer, 
           subscriptionenddate: stripe_subscription.current_period_end) 
    if @sub.save 
     current_user.role plan.id 
     current_user.save 
     flash[:success] = 'sub created!' 
     redirect_to root_url 
    else 
     render 'new' 
    end 
end 

，當它達到更新的角色我得到

ArgumentError: wrong number of arguments (1 for 0) 

我怎麼可以更新角色和我做錯了什麼？

你試過了嗎：current_user.role = plan.id？

看起來您只是在curent_user對象上調用role()方法。
