undefined method `empty?' for nil:NilClass #133

Closed balajibalasubramaniam closed 6 years ago

balajibalasubramaniam commented 7 years ago

Hi, I am trying to run filterrific in jruby rails environment. Initially, there was no errors and was able to run it succesffully. Few days after that I was working on different controller adding some other gems related with charts. When I came to student controller, now it is giving me this error, I have triple verified all the code and also did beyond compare with your demo app and mine. There was no changes in views, controller, model, js, db and config files, but suddenly I am getting this error "undefined method `empty?' for nil:NilClass" in the following line

    .form-group.chardin_box{ :'data-position' => 'top', :'data-intro' => 'Filter by country.' }
      %label Category
      = f.select :with_country_id,
                 @filterrific.select_options[:with_country_id],
                 { :include_blank => '- Any -' },
                 { :class => 'form-control' }

Can you please help?

when I print @filterrific.select_options, then in the console I get the following: {\"sorted_by\"=>[[\"Name (a-z)\", \"name_asc\"], [\"Commited date (newest first)\", \"created_at_desc\"], [\"Commited date (oldest first)\", \"created_at_asc\"], [\"Category (a-z)\", \"country_name_asc\"]], \"with_country_id\"=>[[\"Australia\", 3], [\"Canada\", 2], [\"Ireland\", 7], [\"New Zealand\", 5], [\"Puerto Rico\", 6], [\"South Africa\", 4], [\"United Kingdom\", 8], [\"United States\", 1]]}

@balajibalasubramaniam in the printout of .select_options, you can see that the Hash uses string keys. So in order to make this work, you need to change @filterrific.select_options[:with_country_id] to @filterrific.select_options["with_country_id"]. Notice the String hash key for "with_country_id".
