I got the same “undefined method `url_for’ for nil:NilClass”.

Ttried to add “include ActionView::Helpers::UrlHelper” and “include ActionController::UrlWriter” as Dave suggested but no luck(undefined method ‘include’), I changed “include” to “require” but rails complains “can’t convert Module into String”.

Besides, I need also to use some functions defined in application_helper.rb in the model, how can I do that?

Thanks.

Did you ever figure this problem out? I am running into the same error (undefined method `url_for’ for nil:NilClass) when using link_to in my partial.

Thanks

It looks as though if you add:
include ActionView::Helpers::UrlHelper
include ActionController::UrlWriter
The nil / noMethodEroor gets resolved.

I wanted to use similar technique to render :update. But it gave me an error:

NoMethodError: You have a nil object when you didn’t expect it!
The error occurred while evaluating nil.with_output_buffer

Not sure if I need to include any modules.

I take it link_to/url_for would fit into the situation Joe Goggins mentions above?

I’m trying to render a partial with some links to nested resources and I keep getting this error:

The error occurred while evaluating nil.url_for

I tried out Joe’s sample code as well, still no dice. Anyone have any thoughts?
