如何更新记录在rails控制器

Question

上午使用stripe供用户订阅。从那里我收集条纹日期并保存在订阅模式。我为我的用户模型创建枚举以基于条带订阅ID分配不同的角色。 这里是我的用户模型看起来像

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 

和波纹管是我的用户控制器

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 

，当它达到更新的角色我得到

ArgumentError: wrong number of arguments (1 for 0) 

我怎么可以更新角色和我做错了什么？

你试过了吗：current_user.role = plan.id？

看起来您只是在curent_user对象上调用role()方法。
