Rails 5: Why isn't will paginate working?

Question

I've added the gem, restarted the server.

In my index action I have:

def index
  @listings = Listing.paginate(page: params[:page])
end

I reload my view. It works.

I then drop in the pagination links:

<%= will_paginate @listings %>

I get an error:

ActionView::Template::Error (wrong number of arguments (given 0, expected 1)):
    12: 
    13: <%= render 'shared/subscribe' %>
    14: 
    15: <%= will_paginate @listings %>
    16: <div class="content listings">
    17:   <h1>Latest<span class="meta">updated <%= time_ago_in_words(@listings.first.updated_at) %> ago</span></h1>
    18:   <% @listings.each do |listing| %>

app/views/listings/index.html.erb:15:in `_app_views_listings_index_html_erb___4466103937708592830_70228331044140'

For some reason <%= will_paginate @listings %> isn't working.

In the error console, I can see that the error originates from:

Listing.paginate(page: params[:page])

The full error is:

ArgumentError: wrong number of arguments (given 0, expected 1)

Can anyone see what is going on? I'm completely confused. What is causing the error?

Answer 1

I was using an outdated version of will_paginate .

The problem went away after upgrading to 3.1.7 .

Answer 2

Updating the will_paginate gem to 3.1.7 for Rails 5.2 removed that error mentioned.
