我控制器代碼

class CommentsController < ApplicationController 
http_basic_authenticate_with :name => "test", :password => "test", :only => :destroy 
    def create 
    @post = Post.find(params[:post_id]) 
    @comment = @post.comments.create(params[:comment]) 
    redirect_to post_path(@post) 
    end 

    def destroy 
    @post = Post.find(params[:post_id]) 
    @comment = @post.comments.find(params[:id]) 
    @comment.destroy 
    redirect_to post_path(@post) 
    end 

end 

Answer 1

按照錯誤，您正在使用$end時，你應該使用end。但是，您向我們展示的代碼是正確的。所以，我相信您在heroku上的代碼與您的計算機中的代碼不同。

嘗試再次更新您的代碼github上，然後到Heroku上：

git add . 
git commit -m "update" 
git push 
git push heroko
