With nested object collection in Update

[dinatih]

Hello,

That is my code:

I have a Company and a Position Models,
Company has many :positions and they have both a {Model}Translation Model.

When I create a Company and position in a multiple nested form:
<% form_for @Company do | company_form |%>
<% company_form.field_for :positions do | position_form |%>
<position_form.text_field :name>
<% end %>
<% end %>

Position#name is a translated attribute , all works, but when a i try to update the company and his position names the position name don't update.

And I got a "WARNING: Can't mass-assign these protected attributes: id"

Have you a idea of why that doesn't work please ?

P.S :

i have the same problems using nested attributes but i don't get the mass-assign warning. the translation table gets no update. any ideas?

[dinatih]

This works if we change a non translated attribute at the same time of the translated attributes. So I think this is due to update_attribute method which not update attribute if no non-translated attributes has changed

I see the same happening for me as well. I get the warning, data is written though. I use form_for
