Instance Method Details

#each {|The| ... } ⇒ Enumerable

Executes the given code block with this model and every model that is a child of this model. Exact order of model tree traversal is not guaranteed beyond the first model traversed, which will be the model that called this method. If no block is provided, an ‘Enumerator` is returned instead.

Examples:

model.each
model.each { |model| puts model.inspect }

Yield Parameters:

  • The (Model) —

    current model being visited

Returns:

  • (Enumerable) —

    if no block is given
