heroku上的应用程序错误

Question

我今天上传了一个应用程序到Heroku上，看到这个错误：应用程序错误

应用程序发生错误，您的页面无法送达。请稍后重试。

如果您是应用程序所有者，请查看您的日志以了解详细信息。

这个应用程序在当地工作。这是我的日志。任何人有任何想法？

我控制器代码

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

按照错误，您正在使用$end时，你应该使用end。但是，您向我们展示的代码是正确的。所以，我相信您在heroku上的代码与您的计算机中的代码不同。

尝试再次更新您的代码github上，然后到Heroku上：

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