I have a couple of resources, a grant\_application, and a household  
which are related with a has\_one

class GrantApplication \< ActiveRecord::Base  
has\_one :household, :dependent =\> :destroy  
end

class Household \< ActiveRecord::Base  
belongs\_to :grant\_application  
end

…and I also use the following route…

map.resources :grant\_applications do |grant|  
grant.resource :household  
end

However, I am having real problems when trying to create the form for /  
grant\_applications/1/household/new

Using

\<% form\_for([:grant, @household]) do |f| %\>

returns an error:

undefined method ‘grant\_households\_path’ for #\<ActionView::Base:  
0x23eda44\>

Any ideas?

Hi

```
I think you can do do like

```

\<% form\_for @household, :url =\>  
grant\_application\_household\_path(@grant\_application) do |f| %\>

OR

\<% form\_for [@grant\_application, :household] do |f| %\>

> undefined method ‘grant\_households\_path’ for #\<ActionView::Base:

Yes expects helper grant\_application\_household\_path(:id)
