Question

This is a Rails 3 application with HAML.
I have the following:

= f.fields_for :bar_memberships do |bar_membership_fields|
  = 'FIELD'

I have encapsulated the problem. This code prints:
FIELD
FIELD
FIELD
as expected.

But the following code:

= f.fields_for :bar_memberships do |bar_membership_fields|
  - if bar_membership_fields.object.new_record?
    = 'FIELD'

Renders a lot of HTML-escaped hidden inputs in the source code, and displays them on the page!

'<input id="person_bar_memberships_attributes_0_id" name="person[bar_memberships_attributes][0][id]" type="hidden" value="824" />
<input id="person_bar_memberships_attributes_1_id" name="person[bar_memberships_attributes][1][id]" type="hidden" value="825" />'
FIELD

Any idea?

Answer 1

I fixed the following code:

= f.fields_for :bar_memberships do |bar_membership_fields|
  - if bar_membership_fields.object.new_record?
    = 'FIELD'

By doing:

= f.fields_for :bar_memberships do |bar_membership_fields|
  = ""
  - if bar_membership_fields.object.new_record?
    = 'FIELD'

If anyone knows why please let me know.
