def ignore_unknown_conditions=(boolean)
  self.options[:ignore_unknown_conditions] = boolean
end

#search_key=(name) ⇒ Object

The default ‘search_key` name is `:q`. The default key may be overridden in an initializer file like `config/initializers/ransack.rb` as follows:

Ransack.configure do |config|

# Name the search_key `:query` instead of the default `:q`
config.search_key = :query

end

Sometimes there are situations when the default search parameter name cannot be used, for instance if there were two searches on one page. Another name can be set using the ‘search_key` option with Ransack `ransack`, `search` and `@search_form_for` methods in controllers & views.

In the controller: In the view: <%= f.search_form_for @search, as: :log_search %>
