Hi, I’ve created a business form and an address form using scaffolding  
and I am trying to get the business form to display some information  
from the address form, but I keep getting an “You have a nil object  
when you didn’t expect it! You might have expected an instance of  
Array. The error occurred while evaluating nil.each” error.

17:   
18:  
19: \<% for business in @businesses %\>  
20: \<% for address in @addresses %\>  
21:  
22:

  
23: \<%=h business.address\_id %\>

This is my business index.html form:

# Listing businesses

\<% for business in @businesses %\>  
\<% for address in @addresses %\>

\<% end %\> \<% end %\>

| Address | Business name | Business email | Business telephone | City |
| --- | --- | --- | --- | --- |
| \<%=h business.address\_id %\> | \<%=h business.business\_name %\> | \<%=h business.business\_email %\> | \<%=h business.business\_telephone %\> | \<%=h address.city %\> | \<%= link\_to 'Show', business %\> | \<%= link\_to 'Edit', edit\_business\_path(business) %\> | \<%= link\_to 'Destroy', business, :confirm =\> 'Are you sure?', :method =\> :delete %\> |

  

\<%= link\_to ‘New business’, new\_business\_path %\>

This is my business controller form:

def index  
@businesses = Business.search(params[:search])

```
respond_to do |format|
  format.html # index.html.erb
  format.xml { render :xml => @businesses }
end

```

end

def show  
@business = Business.find(params[:id])  
respond\_to do |format|  
format.html # show.html.erb  
format.xml { render :xml =\> @business }  
end  
end

What have I missed?

Errm… I guess you’ve missed the fact that you haven’t actually loaded  
or assigned @addresses in your controller?

Cheers,

Hi,

You are looping through the addresses this way  
\<% for address in @addresses %\>  
but your controller misses @addresses  
Please mention that in your controller.

Bye!!

it looks that error coming in yours show.html.erb

create a test data fisrt in new.html.erb  
then GoTo show.html.erb

or in show.html.erb Put

\<%= if @object.nil? %\>

\<% there are No data in records %\>

\<%else%\>

yours code

\<% end %\>

ok if works then tell and if not then must reply…
