beginner question...really.


I want to create a select form and based on what the user chooses on
the select form, I want to connect to different tables and display the

I'm clueless on how to go about it.
Any pointers would be appreciated.

The select helper is your friend

i got the select option set up...but how would i get data from
diffrerent tables depending on user's choice?

Hi there,
I'm not sure if this is exactly what you want but it got me going down
the right path a while ago:

This will walk you through getting specific data into the select form
from a db table.

There's also a way to do this with AJAX auto_complete

Hope this helps!


Thanks...i dont think i was clear

im not looking to populate the select form from db table.
im looking to get data off different db tables depending on the choice
that the user makes from the select form.

You can get from different Table of you page form.

If you want create a User and in this page, you have a link to School.

You can made a select for all school that you have with

<%= select :school, school_id, School.find(:all).collect {|s| [, ] } %>

After you have the school_id good for creation and when you made the
creation, you have link to School.

Else, you can define the param as you want and use it like an other params.


if I understand correctly -- the visitor's selection will be available
for you in params hash in your controller. In the controller you can
have some case...when logic, accessing different models = different DB
tables. Is this what you are looking for?
