Instance Method Details

#duplicate(name) ⇒ void

Note:

  • Only models of the same repository can be used in this way.

  • If the stored model cannot be found, the duplicate may not have the values you required.

  • Values defined before will be overwritten by the new values from the stored model.

  • Values defined after will overwrite the values of the new duplicate model.

This method returns an undefined value.

Duplicate a stored model.

This DSL method copies the attributes of a stored model, changes the name to that of the current model, and stores the duplicate as a new model in model’s repository.

Examples:

# Here the attributes of 'my_geometry' are used to create the
# new model 'my_other_geometry'.
Vedeu.geometry 'my_other_geometry' do
  duplicate('my_geometry')
end

def duplicate(name)
  duplicated      = model.repository.by_name(name).dup
  duplicated.name = model.name
  duplicated.store
end

#use(name) ⇒ void

Note:

  • Only models of the same repository can be used in this way.

  • If the stored model cannot be found, a ModelNotFound exception may be raised, or the request for an attribute may raise a NoMethodError exception.

This method returns an undefined value.

Use the attribute of stored model.

This DSL method provides access to a stored model by name. You can then request an attribute of that model for use within the current model.

Examples:

# Here the character used for 'my_border' is used in
# 'my_other_border'.
Vedeu.border 'my_other_border' do
  top_right use('my_border').top_right
end

Raises:

  • (ModelNotFound|NoMethodError) —

    The model or attribute cannot be found.
