Class Method Details

.extract_info(symbol_or_string) ⇒ Object

Deduct the information from Node instance name: will try to get:

name: compulsary
approach: optional

Returns array containing name and approach

Example:

# no apprach
["users", nil]

# ratio apprach
["users", "ratio"]

  [symbol_or_string.to_s.singularize, approach]
end

.valid_structure?(structure) ⇒ Boolean

Method validating structure for Node operations. It will only accepts a structure if it is a Hash object, with one key only. In any other case a false value will be returned

Returns:

#after_initialize ⇒ Object

Just in case Fixturer requires anything to be done after the node initialization

# File 'lib/cockroach/base/node.rb', line 70

def after_initialize
end

#amount ⇒ Object

Keeps the number, that represents the amount of the records that will created for this node. This will be the final number of the records that are going to be created. In case there was a ratio specified, that method will randomly get a number within the provided range and keep it.
