I have used this code, to collect the names by checking the condition in the model

<%=  select_tag "name", options_for_select([["select" , "0" ]] + @names.collect{|p| [p.gatherName(p),p.id]}) %>

if condition fails value returns blank, in that case the otpions are ordered like this,

  <option value='1'></option> 
  <option value='2'>lamrin</option> 
  <option value='3'></option>

while listing the box option 1 is balnk, option 2 has value, and option 3 is blank.

so please help me how to avoid the blank options in the collect

thanks

    Try select or reject in addition to collect, e.g.

    <%=  select_tag "name", options_for_select([["select" , "0" ]] + @names.reject{|p|p.gatherName(p).blank?}.collect{|p| [p.gatherName(p),p.id]}) %>

    I also have to ask why gatherName takes a parameter that is the same as the object it is called on?

    Edit: Doh, too slow I see.
