I have a list of 3 “report\_admins” in my database, and when I send an  
email I need to email to go to all 3 admins,

So in the controller I put…  
@report\_admins = ReportAdmin.find(:all)

Then I told ActionMailer this…  
@recipients = report\_admins.email

But when I try and send this email I get this error…  
undefined method `email’ for #Array:0x455e214

I have been told that I need to change this array into a string, but I  
don’t know how… How?

Hi you can try like this

@report\_admins = ReportAdmin.find(:all)

@recipients=[]

for report\_admin in @report\_admins  
@recipients \<\< report\_admin.email  
end

You can collect the email address of each admin in one line:

@recipients = @report\_admins.collect { |a| a.email }

This way does seem like a much more efficient way of getting and doing  
this, but both ways work.
