Hi  
i have a 1-N Model: Company\<\>Division. everything is default. I want to  
have a Division/new partial in the Company/show view. so what i did was  
copying the new to \_new and render it with:  
Company/show:

**Title:** \<%=h @account.title %\>

.....

\<%= render :partial=\>‘contacts/new’, :local=\>@contact=Contact.new %\>

…

but now i dont know hoe to get the @acount\_id into the Division-Model as  
foreign key!?  
what do i need to do here?

thx

</div>

could you:

\<%= render\_partial ‘contacts/new’, nil, ‘contact’ =\> Contact.new,  
‘account’ =\> @account.id %\>

\<%= render :partial=\>‘contacts/new’, nil, :contact=\> Contact.new,  
:account=\> @account.id %\>

but this didnt work:  
compile error  
/var/www/railapps/TEST5/app/views/accounts/show.html.erb:8: syntax  
error, unexpected ‘,’, expecting tASSOC  
\_erbout.concat(( render :partial=\>‘contacts/new’, nil, :contact=\>  
Contact.new, :account=\> @account.id ).to\_s); \_erbout.concat “\n”

Any difference if you take that nil arg out of there?

If not, maybe this would work:

\<%= render :partial=\>‘contacts/new’, :contact =\> Contact.new(:account\_id  
=\> @account.id) %\>

?
