Class is converting fixnum to array!?!

ruby-talk

Hi all

I have made a class to return a value of either 1 or 0 depending on
conditions, however once it returns the fixnum is converted to an Array?

user = 0

puts user.class # -> fixnum
user = My_class.test(name)
puts user.class # -> Array

class My_class

   self.test(name)
     if name == name then
       return 1
     else
       return 0
      end

   end

end

this is an example and not the true code, the principle is there, the
basics are that when a value is returned it converts user to an
Array???

Thanks all

Stuart

Hello !

user = 0

puts user.class # → fixnum
user = My_class.test(name)
puts user.class # → Array

class My_class

self.test(name)
if name == name then
return 1
else
return 0
end

end

end

There are few things missing in you code, as is, it doesn’t run. It tried to modify it, and then I get the expected results (not the ones you point out).

Could you please provide us with a minimum working example ?

Cheers !

That's exactly the reason why we cannot possibly help you here. The code above clearly does not return an array. Try using "p" to print out the result of calling "test" to get an idea what goes wrong.

this is the full class and code to call it, it out puts fixnum then
array

class Ldap

  def self.auth(name)

    ldap= Net::LDAP.new :host => '172.16.1.1', :port => 389, :auth =>
{:method => :simple,:username => "ldapquery@example.com",:password =>
"password"}
    filter = Net::LDAP::Filter.eq( "samaccountname", "#{name}" )
     treebase = "ou=accounts,dc=example,dc=com"

     ldap.search( :base => treebase, :filter => filter ) do |entry|

      if "#{entry["samaccountname"]}" == "#{name}" then
      return 1
      else
      return 0
      end

    end

  end
end

address = "user@example.com"

username = "#{address}".sub(/@.*/, '')
    puts user.class
    user = Ldap.auth(username)
    puts user.class

What if you never enter that block, because ldap.search never found anything?

Then the result of ldap.search will be returned, probably an empty array.
