[英]Error on Ruby on Rails tutorial
I try to do the Getting Started with Rails tutoriel and I have a problem I don't understand.. 我尝试做Rails入门教程,但有一个我不明白的问题。
I trying to do the part 5.10 Adding Some Validation with the update function but i have an error "We're sorry, but something went wrong." 我尝试执行第5.10部分 ,使用更新功能添加一些验证 ,但出现错误“很抱歉,出了点问题。” and nothing else...
没什么...
I'm sorry for all the code, but i'm a begginer and i realy don't know where is the error :/ 我为所有代码感到抱歉,但是我是一个初学者,我真的不知道错误在哪里:/
The controller : 控制器:
class ArticlesController < ApplicationController
def index
@articles = Article.all
end
def new
@article = Article.new()
end
def create
@article = Article.new(article_params)
if @article.save
redirect_to @article
else
render 'new'
end
end
def show
@article = Article.find(params[:id])
end
def edit
@article = Article.find(params[:id])
end
def update
@article = Article.find(params[:id])
if @article.update(article_params)
redirect_to @article
else
render 'edit'
end
end
private
def article_params
params.require(:article).permit(:title, :text)
end
And if i delete the if/else/end on the update function, it's work (put an other error but not only the sorry message) 如果我删除更新功能上的if / else / end,它就可以工作(输入其他错误,不仅是抱歉的消息)

I have read the log file and I think this line can help you :/ 我已经阅读了日志文件,并且我认为这一行可以为您提供帮助:/

You probably have an invisible control character in your text (perhaps from cut and paste). 您的文本中可能有一个不可见的控制字符(可能是剪切和粘贴)。 Try deleting the if/else statement and retype it by hand.
尝试删除if / else语句,然后手动重新输入。 I know this sounds strange but have seen this kind of thing happen many times.
我知道这听起来很奇怪,但已经多次看到这种事情发生。
