rails pagination for custom queries

Question

I have the following custom query:

@initial_matches = Listing.find_by_sql(["SELECT * FROM listings WHERE industry = ? AND years <= ? AND degree_type <= ?", current_user.industry, current_user.years, @highest_degree])

Any way to paginate the results?

Answer 1

Listing.where(:industry => current_user.industry).where(["years <= ?", current_user.years]).where(["degree_type <= ?", @highest_degree]).paginate

最好将此逻辑移到范围内，以使其看起来更漂亮或更短。

Answer 2

Will_paginate works fine with basic Arrays.

In your controller:

@stuffs = %w(1 2 3 4 5 6 7 8 9 10).paginate(:page => params[:page], :per_page => 4)

In your view:

<% @stuffs.each do |stuff| %>
 <%= stuff %>
<% end  %>
<%= will_paginate @stuffs %>
