Ruby on rails：意外的輸入結束，期待keyword_end

Question

我有一個像控制器中的主題一樣的問題。我有錯誤的期待功能結束。但正如你所看到的，我已經完成了這個功能的每一步。我是RoR的初學者。

class UsersController < ApplicationController 
before_filter :authenticate_user! 

    def show 
    @user = User.find(params[:id]) 
    @user_catalogs = @user.catalogs 
    @hash = Gmaps4rails.build_markers(@user.locations) do |location, marker| 
    marker.lat location.latitude 
    marker.lng location.longitude 
    marker.infowindow location.address 
    end 

    def index 
     @users = User.where.not("id = ?",current_user.id).order("created_at DESC") 
     @conversations = Conversation.involving(current_user).order("created_at DESC") 
    end 
end 

Answer 1

您在show方法錯過end。試試這個：

def show 
    @user = User.find(params[:id]) 
    @user_catalogs = @user.catalogs 
    @hash = Gmaps4rails.build_markers(@user.locations) do |location, marker| 
     marker.lat location.latitude 
     marker.lng location.longitude 
     marker.infowindow location.address 
    end 
    end 

Answer 2

發現

def show 
    @user = User.find(params[:id]) 
    @user_catalogs = @user.catalogs 
    @hash = Gmaps4rails.build_markers(@user.locations) do |location, marker| 
    marker.lat location.latitude 
    marker.lng location.longitude 
    marker.infowindow location.address 
    end <<<<< here! 
    end
