I can't really test this right now but here's a thought:
- If you create a new ReferralProgram with new Pages there shouldn't
be a Page ID in the params because these Pages don't exist yet (If you
assign existing pages double check if a Page with that ID exists).
- If I remember this correctly multiple nested objects have to be in
an array in the params like:
"pages_attributes" => [ {"body"=>"blabla", "subject"=>"blabla"},
{"body" => "blublu", "subject"=>"blublu"} ]
Hope this helps a little!
