#custom_arrows=(opts = {}) ⇒ Object
By default, Ransack displays sort order indicator arrows with HTML codes:
up_arrow: '▼'
down_arrow: '▲'
There is also a default arrow which is displayed if a column is not sorted. By default this is nil so nothing will be displayed.
Any of the defaults may be globally overridden in an initializer file like ‘config/initializers/ransack.rb` as follows:
Ransack.configure do |config|
# Globally set the up arrow to an icon, and the down and default arrows to unicode.
config.custom_arrows = {
up_arrow: '<i class="fa fa-long-arrow-up"></i>',
down_arrow: 'U+02193',
default_arrow: 'U+11047'
}
end

#hide_sort_order_indicators=(boolean) ⇒ Object
By default, Ransack displays sort order indicator arrows in sort links. The default may be globally overridden in an initializer file like ‘config/initializers/ransack.rb` as follows:
Ransack.configure do |config|
# Hide sort link order indicators globally across the application
config.hide_sort_order_indicators = true
end

# File 'lib/ransack/configuration.rb', line 153 def hide_sort_order_indicators=(boolean) self.[:hide_sort_order_indicators] = boolean end |
#ignore_unknown_conditions=(boolean) ⇒ Object
By default Ransack ignores errors if an unknown predicate, condition or attribute is passed into a search. The default may be overridden in an initializer file like ‘config/initializers/ransack.rb` as follows:
Ransack.configure do |config|
# Raise if an unknown predicate, condition or attribute is passed
config.ignore_unknown_conditions = false
end

# File 'lib/ransack/configuration.rb', line 98 def ignore_unknown_conditions=(boolean) self.[:ignore_unknown_conditions] = boolean end |
#sanitize_custom_scope_booleans=(boolean) ⇒ Object
Ransack sanitizes many values in your custom scopes into booleans.
- 1, ‘1’, ‘t’, ‘T’, ‘true’, ‘TRUE’
-
all evaluate to true.
- 0, ‘0’, ‘f’, ‘F’, ‘false’, ‘FALSE’
-
all evaluate to false.
This default may be globally overridden in an initializer file like ‘config/initializers/ransack.rb` as follows:
Ransack.configure do |config|
# Accept my custom scope values as what they are.
config.sanitize_custom_scope_booleans = false
end
140 141 142 |
# File 'lib/ransack/configuration.rb', line 140 def sanitize_custom_scope_booleans=(boolean) self.[:sanitize_scope_args] = 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 %>
