Thanks! This works much better. I didn’t realize link_to had a
:controller property.

Marcus,
When I try your facilities link_to I get a link like:
http://localhost:3000/facilities/../facilities/list?post=true
Which does result in @facilities being nil for me.
You might try rewriting the link as
<%= link_to ‘Return to facilities’, { :controller => ‘facilities’,
:action => ‘list’ }, :post => true %>
The bit that makes the link url itself in the middle should be enclosed
in {} so that rails knows where the hash begins and ends. :post is an
option, not part of the link hash.

Here is my code example:
Fyi - in this example "facility" is the parent table to the
“permits”
table.
Page A (facility) links to page B (permits) using this code, and
it
works fine.
<%= link_to ‘Permits’, { :action => ‘…\permits\list’,
:facilityid =>
facility}, :post => true %>
Page B (permits) then links back to page A(facility), but this
does not
work.
<%= link_to ‘Return to facilities’, :action =>
‘…/facilities/list’,
:post => true %>
The error I get when going from page B -> A, is in this code in
the
facility/list.rhtml:
<% for facility in @facilities %>
The message is that @facilities is nil. "@facilities" gets
initialized
by the controller’s ‘list’ property.
Any thoughts? Should the controller run each time the page is
accessed?
Is there a better way to accomplish what I am trying to do?
Thanks,
Marcus

If you send through some code samples someone might be able to
help.
cheers,
