I''ve just started working with Rails. And I can''t figure out
what
seems to be the easiest thing imaginable. I need to send @ferry.id
from a view in ferry_controller...
<%= link_to ''Add new schedule'', {:controller =>
''schedule'', :action =>
''new'', ferry_id => @ferry.id }%></d>
to a method in schedule_controller...
def new
@schedule = Schedule.new
end
and have that value survive into the ''new'' view where it will
be
returned in Schedule.new(params[:schedule]).
How is this done? I''m must be utterly simple but I can''t
figure it
out.

Re: Any programmer can answer this in 2 sec, but I''m stumped.
Hey Pat
Thanks for the quick reply. I''m still not sure how the @ferry_id
travels from my ferry_controller''s view to the schedule_controller.
Is it something like this:
<%= link_to ''Add new schedule'', {:controller =>
''schedule'', :action =>
''new'', ferry_id => @ferry.id }%>
then this:
def new(*args)
@schedule = Schedule.new :ferry_id => params[:ferry_id]
end
Something stills feels awkward about it.

That''s precisely it, except you''ll use :ferry_id in the link_to call of course. How does it feel awkward to you?

Re: Any programmer can answer this in 2 sec, but I''m stumped.
Hey! It works! I came from C# and .net and it seems to me that the syntax in Ruby and Rails is less clear. I''ve only been at it for a week though...probably just need more time to let it soak in. Thanks for the help, Pat.
