Newbie: undefined method

Ruby
1

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
