you need to use virtual attributes and callbacks to achieve this.  Read 
on
attr_accessor
and http://api.rubyonrails.org/classes/ActiveRecord/Ca...

Sorry Mas, I still don't get what you want.

Have you read on callbacks and virtual attributes?

First you need to determine which area is going wrong.
Firstly is the html that is being generated what you expect.  Have a
look at the html of the page (using View > Page Source or similar in
your browser).  Does that look ok?
Secondly perhaps the data is not being sent to the server correctly.
Look in log/development.log to check that the data is being passed and
the correct action is being called.
Thirdly perhaps there is an error in the action in the controller.
Have a look at the Rails Guide on Debugging and it will show you
techniques you can use to debug your code.

It is really better to only have one question at a time, otherwise the
answers will get confusing.

Colin

so, first i just need to get value from

"<%=select_tag :Status, options_for_select(%w{ Perempuan Laki-Laki})%>"

because my field(field status) in database, i config as Set that have 
two value "Perempuan" ,and "Laki-Laki". but when i just write that 
syntax rails look value from "<%=select_tag :Status, 
options_for_select(%w{ Perempuan Laki-Laki})%>" as null value.

-------------------------------------------------
for second problem i change my model file to be like this:

class Anggotum < ActiveRecord::Base
  set_table_name "anggota"
  attr_accessible :NP, :Nama, :Alamat, :TTL, :Telp, :Email, :Password, 
:Waktu_Daftar, :Posisi, :Jenis_Kelamin
  attr_accessor           :tempat, :tanggal, :as=> :TTL
end

and in my form.html.rb that connect to new.html.rb i add this syntax

<div class="field">
    <%= f.label :ttl %></td><td>
    <%= f.label :":" %></td><td>
    <%= f.text_field :tempat %>
    <tr>
  <td colspan="3" align="right">
    <%= select_date :tanggal %></td></tr>
  </div>

but it make this error
{:as=>:TTL} is not a symbol

can you help me?

Did you type that last line, or copy and paste from your code?

:Status

or

:status

???

Ruby variables are usually snake-case. Classes are camel-case. Which is 
this?

Walter

this one
:Status
i copy it from my code (_form.html.rb file)

i want to make like this

<div class="field">
    <%= f.label :status %></td><td>
    <%= f.label :":" %></td><td>
    <%= f.text_field :Status %>
  </div>

but i didn't want make input from text_field, i want to input from 
select so i change
    <%= f.text_field :Status %>
to
    <%=select_tag :Status, options_for_select(%w{ Perempuan Laki-Laki 
})%>

when i use text_field as input i got the value. but when i change it to 
select, rails say it nill value

i got the solution for my first problem.

but i haven't been got the solution for my second problem... how about 
to concate value form 2 field...

thanks for your help...

It is good practice to post the solution here so that others who find
the thread by searching will see the solution to the problem.

Just concatenate them in the controller, what is the problem?
