Rails - Sep 2008 - Using the collect method to collect to a 2 dimensional array

Hi
   I am trying to collect name and email of a person to an array (Or
hash?) like
[[name1,emailid],[name2,emailid].......] But I dont know how to do that.
I tried like

email_array Contact.get_email_id_and_name_of_contacts(problem.reported_by_id)
unless
problem.reported_by_id.blank?

And in Contact class

def self.get_email_ids_of_contacts(contact_id)
  return  Contact.find_by_id(contact_id).name,
Contact.find_by_id(contact_id).contact_email_addresses.find(:all,
:conditions =>
[''contact_email_address_type_id=?'',2]).collect { |mail|
mail.email}
end

      Here I tried to return two value at a time .But not suceeded .How
can I do that?Please help

Sijo

Collect just bungs whatever your block evaluates to in an array. If  
that block evaluates to an array then you''ll get an array of arrays  
back.

Sijo,

not sure, but looking at your code it seems you may want to do something 
like the following

def self.get_email_ids_of_contacts(contact_id)
  contact = Contact.find_by_id(contact_id)

  contact.contact_email_addresses.find(:all, :conditions => []).map do 
|mail|
    [contact.name, mail.email]
  end
end

Hi
    Lots of thanks for your great reply.This is what i needed.Now it 
works. But I have one more problem. I have to find group managers name 
and email like above and I tried like below
name_and_email_managers=Group.get_managers_name_and_emails(problem.primary_assignee_group_id)
unless problem.primary_assignee_group_id.blank?

And now in Group class
def self.get_managers_name_and_emails(grp_id)
    managers=Group.find_by_id(grp_id).contacts.find(:all,:conditions => 
[''group_user_type_id = ?'',4])
    managers.each do |manager|
      manager.contact_email_addresses.find(:all, :conditions => 
[''contact_email_address_type_id=?'',2]).map do |mail|
        [manager.name,mail.email]
      end
    end
end
        But this does not give array like above?Could you please tell me 
where is the fault?A group may have more than one manager and each 
manager has more than one email addresses of the above type.That is why 
I wrote code like above  Groups and Contacts are connected through user 
groups (has_many :through relation)

You''re generating these arrays using map but then you''re just
throwing
them away (each returns the collection it iterated over. Perhaps you
mean that to be map or inject instead to concatenate the various
arrays produced?
