Rails: render doesn't work, still get `Template is missing`

Question

I am currently learning Rails Guides. I went through the steps but still encountered a mistake.

My Ruby version is ruby 2.1.1p76 and the Rails version is 4.0.4.

As the guide directed, I created an Article Controller.

class ArticlesController < ApplicationController   def new   end    def create     render plain: params[:article].inspect   end  end 

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]}.` 

Here is my related routes:

articles GET    /articles(.:format)          articles#index          POST   /articles(.:format)          articles#create

Update: render plain: is a new method introduced in Rails 4.1.0 referred to this issue.

Answer 1

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.

Refer to the discussion on this topic on Github: Introduce render :plain and render :html, make render :body as an alias to render :text

Now, for using the below mentioned syntax you would need to upgrade to Rails 4.1:

render plain: params[:article].inspect 

With your current version of Rails 4.0.4, you can go for:

render text: params[:article].inspect
