问题描述
我目前正在学习 Rails 指南.我按照步骤做了,但还是遇到了错误.
I am currently learning Rails Guides. I went through the steps but still encountered a mistake.
我的 Ruby 版本是 ruby 2.1.1p76
,Rails 版本是 4.0.4
.
My Ruby version is ruby 2.1.1p76
and the Rails version is 4.0.4
.
按照指南的指示,我创建了一个文章控制器
.
As the guide directed, I created an Article Controller
.
class ArticlesController < ApplicationController
def new
end
def create
render plain: params[:article].inspect
end
end
我应该得到 {"title"=>"First article!", "text"=>"This is my first article."}
但结果是 >
I should get {"title"=>"First article!", "text"=>"This is my first article."}
but the output turned out to be
Template is missing
Missing template articles/create, application/create with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :raw, :ruby, :jbuilder, :coffee]}.`
这是我的相关路线:
articles GET /articles(.:format) articles#index
POST /articles(.:format) articles#create
更新:render plain:
是 Rails 4.1.0
中引入的新方法,引用 这个问题.
Update: render plain:
is a new method introduced in Rails 4.1.0
referred to this issue.
推荐答案
在render
方法中,Rails 4.1
中增加了plain
选项并且您正在使用 Rails 4.0.4
.所以,rails 忽略了这个选项并开始寻找一个名为 articles/create
的模板,就像你在 ArticlesController#create
动作中一样.显然,模板不存在,因此您会收到错误Template is missing
.
In the render
method, plain
option was added in Rails 4.1
and you are using Rails 4.0.4
. So, rails ignored this option and started looking for a template named articles/create
as you are in ArticlesController#create
action. Obviously, the template doesn't exist so you get the error Template is missing
.
请参阅 Github:介绍 render :plain
和render :html
,让 render :body
作为 render :text
的别名
Refer to the discussion on this topic on Github: Introduce render :plain
and render :html
, make render :body
as an alias to render :text
现在,要使用下面提到的语法,您需要升级到 Rails 4.1
:
Now, for using the below mentioned syntax you would need to upgrade to Rails 4.1
:
render plain: params[:article].inspect
使用当前版本的 Rails 4.0.4
,您可以:
With your current version of Rails 4.0.4
, you can go for:
render text: params[:article].inspect
这篇关于Rails:渲染不起作用,仍然得到`模板丢失`的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
