Instance variables created in controller are nil in view

Rails
1

Hi all.

I’m new to RoR and trying to figure out instance variables. I’m trying
to put a string in one in the controller and
print it in the view. However I’m getting the following error:

NoMethodError in Say#hello

You have a nil object when you didn’t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.+

Apparently the @text variable remains nil, even though I assign a
string to it. Any ideas about what goes wrong?

This is my controller code:

class SayController < ApplicationController
def Hello
@text = ‘Hello world from the controller’
end
def Goodbye
end
end

This is my view:

Rails test (say)

Hello world!

<%= 'testje ' + @text %>

Have you tried:

testje <%= @text %>

3

It shows the text ‘testje’, but there’s no output for the @text
variable.

Change the method names to lower case.

It works! Thank you so much. I never would have thought about that.
