Hi,
When updating a ReferralProgram object that has nested Pages in it I
get the error in the subject line.
Rails generates parameters that look like this:
{"pages_attributes"=>{"0"=>{"body"=>"blabla",
"subject"=>"blabla",
"id"=>"1"}}}
When the id parameter is removed like this:
{"pages_attributes"=>{"0"=>{"body"=>"blabla"}}}
The exception is not raised. Any ideas on this?
The relevant part that 'crashes' the form:
form.html.haml
---
- form.inputs :name => I18n.translate("strings.pages") do
- form.semantic_fields_for :pages do |pages|
%h3= pages.object.title
%div.page_description= pages.label :description, pages.object.description
= pages.input :subject unless pages.object.name.eql?("thankyou_page")
= pages.input :body
Example console session:
ru...@user-laptop:~/rails/1referralprogram$ script/console
Loading development environment (Rails 2.3.8)
h = {"pages_attributes"=>{"0"=>{"body"=>"blabla",
"subject"=>"blabla",
"id"=>"1"}}}>> h = {"pages_attributes"=>{"0"=>{"body"=>"blabla",
?> "subject"=>"blabla",
?> "id"=>"1"}}}
=> {"pages_attributes"=>{"0"=>{"body"=>"blabla", "id"=>"1",
"subject"=>"blabla"}}}
>> r = ReferralProgram.new(h)
