語法錯誤，意外的'）'，期待keyword_then或';'或'\ n'

Question

這個錯誤與什麼有關？我找不到它的代碼不正確？

用戶 Index.html.erb

<%= @events.all.each do |event| %> 
    <%= if current_user.activities.include?(event.activity) %> 
    <%= event.activity %> 
    <%= event.description %> 
    <%= event.start_time %> 
    <%= event.end_time %> 
    <%= event.num_attendees_requested %> 
    <%= event.location_name %> 
    <%= event.street_address %> 
    <%= event.city %> 
    <%= event.state %> 
    <% end %> 
<% end %> 

用戶控制器

class UsersController < ApplicationController 
    def index 
    @users = User.all 
    @activities = Activity.all 
    @events = Event.all 
    end 

    def show 
    @user = current_user 
    @events = Event.all 
    @activities = Activity.all 
    end 

Answer 1

<%= if current_user.activities.include?(event.activity) %> 

到

<% if current_user.activities.include?(event.activity) %>
