I get “undefined method `name’ for #TSPProcess:0x38c7fc0” when I  
access the page with the template:

\<% @processes.each do |asd| %\>

 \<%= render(:inline =\> "#{process.name}")%\> \<% end %\>

The TSPProcess.rb is:

class TSPProcess  
@name = “Nothing”  
attr\_reader :name  
attr\_writer :name  
end

I tried defining name and name= and I get the same error.  
The controller:

require ‘TSPProcess’  
class ProcessesController \< ApplicationController  
def index  
@processes = Array.new  
a = TSPProcess.new  
@processes \<\< a  
end  
end

Any help for a beginner?

The template should read:  
\<% @processes.each do |process| %\>

 \<%= render(:inline =\> "#{process.name}")%\> \<% end %\>

The @name could be causing some problems. If you really want a  
default of “Nothing”, you should move it to the #initialize method.

def initialize  
@name = “Nothing”  
end

Try:

class TSPProcess  
attr\_accessor :name  
end

and in your template:

\<% @processes.each do |process| %\>

 \<%= render(:inline =\> "#{process.name or "Nothing"}")%\> \<% end %\>

> require ‘TSPProcess’

You should ruby’s convention for file-naming: require ‘tsp\_process’

> class ProcessesController \< ApplicationController  
> def index  
> @processes = Array.new  
> a = TSPProcess.new  
> @processes \<\< a  
> end  
> end

You could shorten this to:  
class ProcessesController \< ApplicationController  
def index  
@processes = [TSPProcess.new]  
end  
end
