Hi there, it''s kind of a weird problem. I have a Person model and
Person controller. In the new method in my controller I try to retrieve
a collection of nationalities. The nationalities are stored in a
different table. So retrieving those should be like:
def new
@person = Person.new
@person.name = Name.new
@person.birthday = Date.today
@person.nationality = Nationality.new
nationalities = Nationality.find( :all )
end
Unfortunately when Rails try to access the array in the new.rhtml it''s
nil. Here, I create a selection list, as follows:
<p>
<% form_for :gender do |form| %>
<%= form.select( :gender, @genders ) %>
<% end %>
</p>
The weird thing happens when I retrieve the array inside new.rhtml.
It''s working here.
<p>
<% form_for :nationality do |form| %>
<% @nationalities = Nationality.find( :all )
form.select( :nationality, @nationalities )
%>
<% end %>
</p>
As stated in the new Web Development book those code should normally
reside in the controller.
Am I missing something?
Thanks ahead,
Christian

Try using an instance variable (@nationalities) in the controller instead of a local variable (nationalities). Instance variables are available in the views, but local variables created in the controller method are not.

Thanks Jason, I''m coming from C++ and though I''m probably more used to C++ way of compiler errors. If an variables is not accessible in the current scope why not just state that. But I guess Ruby is on a lot of ways different to C++. Anyway thanks, that was the solution.
