The "render text:" in #show does not work. I get the error message: "Missing template pages/show". Why is it still looking for a template although we are using "render text"?
This is the code snippet:
def show
render text: params[:id]
end

Courses Plus Student 9,868 PointsI think the issue has to do with the version of rails one is running -- I'm locally (localhost) running 5.1.1 and I got the same error. Switching out render text with render plain worked.
However, render text works fine in my remote environment which is using rails 4.2.5.
If Jay was using rails 5 when this video was made, maybe the latest version of rail's (5.1.1)caused the issue...?

Treehouse Teacheryvesramos I'll update the teacher's notes to mention plain.
Both text and plain work in Rails 5.0, which is the recommended version for this course. It's important to use the recommended versions of libraries when following along with tutorials. This is just one example of the incompatibilities that can happen when the versions differ.
You can install Rails 5.0 with this command:
gem install rails --version 5.0.0
As I write, this installs Rails 5.0.4, which is okay because (unlike 5.1.2) its API is still fully compatible with 5.0.0.
rails new uses the newest version of Rails installed on your system by default. If you already have a more recent version of Rails (such as 5.1) installed on your system, and you don't want to uninstall it, you'll need to ensure that you're using 5.0.0 when generating a new app. Use this command:
rails _5.0.0_ new blog
Once you change into your app's directory, as long as you're running commands using bin/rails (which is what we suggest in the course), it should use the version of Rails that the app was generated with.

12,816 PointsThanks, Zia Khan. It worked with plain:. For those having the same issue and wonder why we can not use text: it is because is deprecated. This link might help(https://apidock.com/rails/ActionController/Base/render). I am not sure, but I think they removed it in rails 4.2. Jay, you should test it and add it in the teacher notes.

9,291 PointsWith Rails 5.1.4 I have used:
def show
@page = Page.find(params[:id])
render plain: @page.title
end
or you can use render text: @page.title, but you should create app/views/pages/show.html.erb if you don't want to get 'Template is missing' error :)

Treehouse TeacherThat's strange; I would expect it to work. I wonder if your routes are set up correctly, or if there's another problem.
Can you go to your terminal, clear all text (or hit Enter a few times to mark so there's a gap after the existing text), make another browser request for
localhost:3000/pages/4, and then copy and paste all new text that appears in the Rails log here?
