Insert select statements from different database

i want to insert a select field into my form.
The fields of the select-field should come from a database that is
created in a different modell in the same project.
I don´t need relations simply the content from one field in the table
that should populate the select-field.
How can i do this?
The selected item from the select-field will then be saved amoung other
fields in a second database
tia for a hint!

Thanks, i know the helper method, but i do not know how to reference to
the database…
assume i am in the model “a” in the view “”
how do i implement the creation of the object in the controller of “a”
to access the datas from model “b”
So as i am a beginner, there seems to be a lack in the knowledge of
so any help would be useful.

Hi Einar,

If I understand your question correctly, you are looking for the
collection_select helper. Here is an example I have in my current
<%= f.collection_select(:user_id, @users, :id, :name) %>

This helper method provides the opportunity to present parameters from
an unrelated object to the user for selection. Be sure to create the
object in the controller method.

Hope this helps.

I see. Again, assuming I understand your question, in your controller
you have a method “def new”. In that method you probably have a
statement something like this:
@a =
You would add a second line:
@b = b.find(:all)
This will create an object of the b model class, which can then be
used in the a/new.html.erb view.

Hope this helps.
