Rails - render partial collection as not working

I am trying to render a partial of a collection using a name different to that of the model:

<%= render "current_campaigns", collection: @current_campaigns, as: :current_campaign %>

The model is called Campaign but this is a subset of campaigns as defined in the controller action:

def index
  @current_campaigns = Campaign.where(status: :approved)
end

In the partial (which lives in the application directory not the campaigns directory):

<%= current_campaign.question %>

The resulting error:

undefined local variable or method `current_campaign' for #<#<Class:0x007fad3d5e5500>:0x007fad451976a8>

I was under the impression that as would make this work but apparently not. Any thoughts?

Try the following <%= render partial: 'path-relative-to-views/current_campaigns', collection: @current_campaigns, as: :current_campaign %> And the partial should name _current_campaign.html.erb for convention.

Try to rename campaigns/current_campaigns.html.erb template to campaigns/campaign.html.erb and render like that from campaigns/:

<%= render @current_campaigns %>

Otherwise you can specify name of directory where the partial is:

<%= render "other_folder_name/campaign", collection: @current_campaigns %>

The most simple way to pass attributes to the partial using a custom name is:

<%= render "current_campaigns", custom_name: @current_campaigns %>

doing this you will be able to use custom_name as a defined variable on your partial.
