Hi  
I have to collect mail addresses like below

Contact.find\_by\_id(problem.reported\_by\_id).contact\_email\_addresses.find(:all,  
:conditions =\> [‘contact\_email\_address\_type\_id=?’,2])

Executing above what i am getting is two objects of class  
ContactEmailAddress and in that an email field is there. For example  
removed\_email\_address@domain.invalid and removed\_email\_address@domain.invalid  
So how can I collect this to an array ? I tried like

EmailArray \<\<  
Contact.find\_by\_id(problem.reported\_by\_id).contact\_email\_addresses.find(:all,  
:conditions =\> [‘contact\_email\_address\_type\_id=?’,2]).collect { |mail|  
mail.email}

```
  But is not working.Could you please tell me how I can achieve

```

this?The above is clearly problem.reported\_by\_id (ie MailIds of  
ReportedBy person) My code continues like

Contact.find\_by\_id(problem.analyst\_id).contact\_email\_addresses.find(:all,  
:conditions =\> [‘contact\_email\_address\_type\_id=?’,2])  
Please note analyst\_id above…I have to do the same thing to this  
also ie to collect mails of Analyst also like above to the same  
EmailArray…Like that

Thanks in advance  
Sijo

Hi  
Here I tried like  
email\_array = Contact.get\_email\_ids\_of\_contacts(problem.reported\_by\_id)  
unless problem.reported\_by\_id.empty?  
It worked and I got the two mailIDs But when I add the next line  
like  
email\_array = email\_array +  
Contact.get\_email\_ids\_of\_contacts(problem.analyst\_id) unless  
problem.analyst\_id.empty?

```
 Now it is not working What might be the cause.Please help

```

Note:  
In get\_email\_ids\_of\_contacts of Contact model just wrote  
return  
Contact.find\_by\_id(contact\_id).contact\_email\_addresses.find(:all,  
:conditions =\> [‘contact\_email\_address\_type\_id=?’,2]).collect { |mail|  
mail.email}
