To configure any of these variables you can do the following:
config/application.rb or one of the environment configurations (e.g.
config/environments/development.rb) you can set
config.neo4j.variable_name = value where variable_name and value are as described below.
Other Ruby apps¶
You can set configuration variables directly in the Neo4j configuration class like so:
Neo4j::Config[:variable_name] = value where variable_name and value are as described below.
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
ActiveRelobjects, should there be a root in the JSON of the model name.
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_postthen the relationship type in the database will be
- Causes the type to be downcased and preceded by a #
- Uses the type as specified
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.
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’.
Loggerobject which is used to log Cypher queries (info level is used)
If true, format outputted queries with newlines and colors to be more easily readable by humans
A Rails-inspired configuration to manage inclusion of the Timestamps module. If set to true, all ActiveNode and ActiveRel models will include the Timestamps module and have
This method returns the specified default type for the
:updated_attimestamps. You can also specify another type (e.g.
