Constructor Details

#initialize(options = {}, &block) ⇒ Profile

Initialization of Input objects follows that of the parent Term class. The interface attribute of self is set to :drop_down by default if a list of choices is defined using the choices attribute. Otherwise the interface attribute is set to :test_box, but can be manually configured if required.

#amee_ivd ⇒ Object

Return the AMEE::Admin::ItemValueDefinition object associated with self.

def amee_ivd
  parent.amee_ivds.detect{|x|x.path==path}
end

#compulsory?(usage = nil) ⇒ Boolean

Return true if the value of self is required before the parent calculation can be calculated. Otherwise, return false.

If no argument is provided, compulsory status is determined according to the current usage of the parent calculation. Compulsory status can be determined for a specific usage by passing in the usage path as an argument

Returns:

  • (Boolean)

def compulsory?(usage=nil)
  usage||=parent.current_usage
  usage ? amee_ivd.compulsory?(usage) : super()
end

#in_use?(usage) ⇒ Boolean

Return true if the value of self is either compulsory OR optional in the owning calculation, i.e. is NOT forbidden.

If no argument is provided, the optional/compulsory status is defined according to the current usage of the parent caluclation. Otherwise, optional/compulsory status is determined on the basis of the usage whose AMEE platform path matches usage

Returns:

  • (Boolean)

def in_use?(usage)
  compulsory?(usage)||optional?(usage)
end

#optional?(usage = nil) ⇒ Boolean

Return true if the value of self is NOT required before the parent calculation can be calculated. Otherwise, return false.

If no argument is provided, optional status is determined according to the current usage of the parent calculation. Optionality can be determined for a specific usage by passing in the usage path as an argument

Returns:

  • (Boolean)

  usage||=parent.current_usage
  usage ? amee_ivd.optional?(usage) : super()
end

#out_of_use?(usage) ⇒ Boolean

Return true if the value of self is neither compulsory OR optional in the owning calculation, i.e. is forbidden.

If no argument is provided, forbbiden status is defined according to the current usage of the parent caluclation. Otherwise, it is determined on the basis of the usage whose AMEE platform path matches usage

Returns:

  • (Boolean)

  !in_use?(usage)
end

#valid? ⇒ Boolean

Returns true if the value set for self is valid. If self contains neither a custom validation pattern nor any defined choices, true is returned. Otherwise, validity depends on the custom validation being successful (if present) and the the value of self matching one of the entries in the choices attribute (if defined). Otherwise, returns false.

Returns:

  • (Boolean)
