I try to update a nested model (version) and get this error. any tips
would be great!

my models: location has_many :versions

# view

<% form_for location do |location_form| %>
<ul class="location">
<li><%= location_form.label location.section %></li>
<li><%= location_form.label location.sub_section %></li>
<li><%= location_form.label location.place_holder %></li>
</ul>

<div class="content-area">
<% location.versions.each do |version| %>
<div class="content" >
<% location_form.fields_for version do |version_form| %>
<%= version_form.label version.environment %>
<%= version_form.text_area :content %>
<% end %>
</div>
<% end %>
<%= submit_tag %>
</div>

<% end %>

#controller

def update
@location = Location.find(params[:id])
@location.update_attributes(params[:location]) #error: unknown
attribute: version
redirect_to( locations_path )
end

# the params

Hi Oren,

Try this "accepts_nested_attributes_for :versions" in the location.rb
file.

Cheers!

I already have this:

has_many :versions, :dependent => :destroy
accepts_nested_attributes_for :versions

[oren]

I use version and not :vorsion here: (since i believe i need to
provide an object)
location_form.fields_for version do |version_form|

could it be related to the issue?

[Nicolas Iensen]

This is how I did my nested forms (actually I have 3 forms nested):

<% form_for [@resource, @validity] do |f| %>
<% f.fields_for :timesheets do |t| %>
<% t.fields_for :values do |v| %>
R$ <%= v.text_field :value, :maxlength=>10 %>
<% end %>
<% end %>
<%= f.submit "Save" %>
<% end %>

resource has_many validities
validity has_many timesheets
timesheet has_many values

[oren]

It works now. I had 2 loops and had to remove the external one:

<% location.versions.each do |version| %>

fields_for already create a loop on the children, so there is no need
for another loop.

thanks!
