See: ActiveRecord::Base (search
“serialize”) …If you want to be able to be able to select by that
field you’ll need a custom serializer and PostgreSQL so you can use
Hstore (you can also use JSON datatype in PostgreSQL 9.2 but that
requires even more work because JSON is still a new feature so it
doesn’t have the same select support that Hstore has.)

i edit 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
serialize :TTL
string “tempat”
date “tanggal”
#{’:TTL’} << #{‘tempat’] + #{‘tanggal’}
end

and change the field in _form.html.rb file to be like this:
…

<%= f.label :ttl %> <%= f.label :":" %> <%= f.text_field 'tempat' %> <%= date_select 'tanggal', 'tanggal', {:start_year => 1950, :order => [:month, :day, :year]} %> ........

rails say this error

"NoMethodError in AnggotaController#index

undefined method `key?’ for nil:NilClass"

so, did you mean. i must 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
serialize :TTL
#{’:TTL’} << #{’:tempat’] + #{’:tanggal’}
end

Have a good look at the Rails Guide on Debugging. It will show you
how to debug your code.

Also I suggest that you work right through a good tutorial on Rails,
such as railstutorial.org, which is free to use online. Then you will
get a better understanding of how Rails works.

I told you to read on virtual attributes and callbacks. To give you a
clue on what you need to do, you need to create 2 virtual atteibutes:
one for the text field and one for the date select. Then use a before
validation callback to concatenate them. Or just as colin suggested,
concatenate them in the controller but i’d like to so these things in
the model.

You are right of course Jim, I was just trying to make it easier for
the guy to understand, but yes, Mas B. it is better to put such code
in the model.
