Configuration¶

class_name_property

Default: :_classname

Which property should be used to determine the ActiveNode class to wrap the node in

If there is no value for this property on a node the node`s labels will be used to determine the ActiveNode class

transform_rel_type

Default: :upcase

Available values: :upcase, :downcase, :legacy, :none

Determines how relationship types as specified in associations are transformed when stored in the database. By default this is upper-case to match with Neo4j convention so if you specify an association of has_many :in, :posts, type: :has_post then the relationship type in the database will be HAS_POST

:legacy: Causes the type to be downcased and preceded by a #
:none: Uses the type as specified

module_handling

Default: :none

Available values: :demodulize, :none, proc

Determines what, if anything, should be done to module names when a model’s class is set. By default, there is a direct mapping of model name to label, so MyModule::MyClass results in a label with the same name.

The :demodulize option uses ActiveSupport’s method of the same name to strip off modules. If you use a proc, it will the class name as an argument and you should return a string that modifies it as you see fit.

association_model_namespace

Default: nil

Associations defined in node models will try to match association names to classes. For example, has_many :out, :student will look for a Student class. To avoid having to use model_class: ‘MyModule::Student’, this config option lets you specify the module that should be used globally for class name discovery.

Of course, even with this option set, you can always override it by calling model_class: ‘ClassName’.

logger

Default: nil (or Rails.logger in Rails)

A Ruby Logger object which is used to log Cypher queries (info level is used)
